Description

内容数据下载和解析***及方法技术领域 Content data downloading and parsing system and method

本发明涉及内容数据下载***和方法。特别是实现诸如播放内容数据及电子节目指南之类的服务信息的下载和解析的***及方法。背景技术 The present invention relates to a content data download system and method. In particular, systems and methods are implemented for downloading and parsing service information such as content data and electronic program guides. Background technique

在广播电视领域中，随着数字电视的飞速发展以及用户要求的不断提高，电子节目指南（EPG) 业务逐渐成为当前模拟电视以及未来数字电视（DVB) 的一个重要组成部分。在模拟电视时代，由于频道数目有限，人们可以通过简单的遥控器遍历方法搜索自己喜爱的电视节目。.然而，随着数字时代的到来，频道数目急剧增加，频道数从几十个变为几百个，这样一来，简单的遍历将成为一种负担，而且很容易错过用户希望观看的节目。 EPG 业务基于类似因特网的业务交互，能及时提供丰富的、最新的节目预告信息，并能供用户简洁而快速地进行节目内容检索，从而极大推动电视传播业务的发展。 In the field of broadcast television, with the rapid development of digital TV and the increasing demands of users, the Electronic Program Guide (EPG) service has gradually become an important part of current analog TV and future digital television (DVB). In the analog TV era, due to the limited number of channels, people can search their favorite TV programs through a simple remote control traversal method. However, with the advent of the digital age, the number of channels has increased dramatically, and the number of channels has changed from dozens to hundreds, so that simple traversal will become a burden, and it is easy to miss the programs that users want to watch. The EPG service is based on Internet-like business interactions, providing rich and up-to-date program preview information in a timely manner, and allowing users to easily and quickly retrieve program content, thus greatly promoting the development of TV communication business.

所谓电子节目指南（EPG， Electronic Program Guide) 实际就是一种应用于电视观看的实时节目报表，该节目报表可以随时调阅、约定节目。目前 EPG两个主要的使用方式是：节目预定和节目浏览。对于节目预定来说，其基本功能是利用 EPG提供的信息对未来播出的节目进行安排，包括节目录制、节目提醒等等，用户可以根据 EPG 提供的信息预先设定自己期望观看的节目，那么，在希望的时间就会自动切换到设定的频道进行节目观看或是节目录制。对于节目浏览来说，其基本功能是利用 EPG提供的信息对未来播出的节目掌握播出时间，了解节目内容概要，类似于目前用户翻阅电视节目报纸。 The so-called Electronic Program Guide (EPG) is actually a real-time program report for TV viewing. The program report can be read and agreed at any time. At present, the two main uses of EPG are: program reservation and program browsing. For the program reservation, its basic function is to use the information provided by the EPG to arrange the programs to be broadcasted in the future, including program recording, program reminder, etc., the user can pre-set the program that he or she desires to watch according to the information provided by the EPG, then At the desired time, it will automatically switch to the set channel for program viewing or program recording. For program browsing, the basic function is to use the information provided by the EPG to master the broadcast time of the programs broadcasted in the future, and to understand the summary of the program content, similar to the current user flipping through the TV program newspaper.

可以看出， EPG—方面可以为用户查找和定位电视节目提供实时的帮助，另一方面可以为用户提供更多的电视节目以外的内容信息，比如：査看节目名称、节目送播时间（段）、节目的演员信息、节目的内容简介甚至节目预告片段、利用所提供的节目单信息检索定位自己所喜欢的节目。有了时间、简介等信息，用户可以实现个性化的定时录制服务，例如：按照特定频道设定的定时录制、按照节目时间设定的定时录制以及按照节目内容简介设定的定时录制等等。总之， EPG 能够为用户提供丰富的节目信息，满足用户多样的需求。目前， EPG业务***采用两种不同的方式向用户提供 EPG节目指南信息：一种方式是通过诸如以太网或无线网络之类的网络向用户下载，也称之为在线 EPG (Online EPG)。这种方式下的 EPG信息一般为可扩展标记语言（Extended Mark Language) XML 格式、或文本格式（TXT, Text ), 各自有具体的字段定义，这种方式对模拟电视或数字电视均适用。另外一种方式是集成于数字电视（DVB-C) 视频***流（Video System Streaming) 中，可称之为文字电视广播 EPG (Teletext EPG)。该方法将 EPG等服务 / 用户信息（SI， Service/Subscriber Information) 基于 MPEG2_System标准，通过特殊的打包器（Packager) 打包成基本信息包流（EPS, Elementary Packet Stream) 或传输流（TS， Transformation Stream),然后通过 DVB- C传输标准从发送前端（Head- end) 传输到终端用户设备上，该方式只适用于数字电视节目播放***和接收设备中。 It can be seen that the EPG-side can provide real-time help for users to find and locate TV programs, and on the other hand can provide users with more content information than TV programs, such as: View program name, program delivery time (segment ), the actor information of the program, the content profile of the program, and even the program preview segment, and use the provided program listing information to retrieve and locate the program that they like. With time, profile and other information, users can implement personalized timed recording services, such as: timed recording according to specific channel settings, timed recording according to program time setting, and timed recording according to program content profile. In short, EPG can provide users with rich program information to meet the diverse needs of users. Currently, the EPG service system provides EPG program guide information to users in two different ways: One way is to download to users via a network such as Ethernet or wireless network, also known as Online EPG (Online EPG). The EPG information in this way is generally an Extended Mark Language (XML) format, or a text format (TXT, Text), each having a specific field definition, which is applicable to both analog television and digital television. Another way is to integrate it into a digital television (DVB-C) video system stream (Video System Streaming), which can be called a teletext EPG (Teletext EPG). The method packs service/subscriber information (SI, Service/Subscriber Information) such as EPG into a basic packet stream (EPS, Elementary Packet Stream) or transport stream (TS, Transformation Stream) based on the MPEG2_System standard through a special packager (Packager). ), and then transmitted from the transmitting front-end (Head-end) to the end-user device through the DVB-C transmission standard, which is only applicable to the digital television program broadcasting system and the receiving device.

目前在模拟电视和数字电视上广泛使用的 EPG业务主要为 Online EPG方式，也就是终端设备需要直接连接以太网或通过无线方式连接进入以太网，从而从特定的 EPG 服务器上下载所需的 XML格式或 TXT格式的 EPG节目单，在终端设备上解析后，按相应字段信息来获取相应的节目信息。 Currently, the EPG service widely used in analog TV and digital TV is mainly the Online EPG mode, that is, the terminal device needs to directly connect to the Ethernet or wirelessly connect to the Ethernet to download the required XML format from the specific EPG server. Or the EPG program list in the TXT format, after parsing on the terminal device, obtain corresponding program information according to the corresponding field information.

参见图 1所示，现有 EPG业务信息制作及发送***包括以下几部分。 Referring to FIG. 1, the existing EPG service information creation and transmission system includes the following parts.

节目源***，用于提供节目单信息，包括节目单服务部分、节目单编辑部分、节目单文件转换部分三个部分。其中，节目单编辑部分将节目的基本信息以及附属信息进行编排，以 XML格式输出成节目单。节目单文件转换部分主要用于将 TXT格式的节目单转换为 XML格式的节目单。节目单服务部分用于接收来自节目单编辑部分或节目单文件转换部分输出的 XML格式的节目单，进行格式校验，并在校验成功后输入信息数据库。 The program source system is configured to provide program order information, including a program list service part, a program list editing part, and a program order file conversion part. The program part editing section arranges the basic information of the program and the subsidiary information, and outputs the program list in an XML format. The program file conversion section is mainly used to convert a program list in the TXT format into a program list in an XML format. The program list service portion is configured to receive a program list in an XML format outputted from the program list editing portion or the program file conversion portion, perform format verification, and input the information database after the verification is successful.

***管理部分，主要完成网络信息、传输流信息、 SI业务信息以及条件接收（CA， Condition Access)***配置的管理，同时也包括对程序服务信息 /服务信息（PSI/SI， Program Service Information/Service Information) 的配置管理。 The system management part mainly completes the management of network information, transport stream information, SI service information, and conditional access (CA, Condition Access) system configuration, and also includes program service information/service information (PSI/SI, Program Service Information/Service). Configuration management of Information).

PSI/SI生成器，主要用于生成 PSI/SI信息表格，该信息表格以节目段（Section) 和 TS的形式依据 DVB-C/MPEG II标准生成，其标准字段地描述如图 2所示，其中的 vl、 v2表示 DVB标准中对应标准描述符的不同版本信息。根据这些 PSI/SI信息，用户终端可以解析出很多信息，比如：网络运营商名称（ Network—Name )、卫星传送 ( Satellite_Delivery ) 或线缆传送（ Cable_Delivery )、 CA 条件接收标识 (CA_Identifier) 等等信息，便于终端用户更好地使用和接收，同时，在该 PSI/SI 生成器中网络运营商也可以依据自己的运营状况开发并提供给用户一些个性化的应用服务。 The PSI/SI generator is mainly used to generate a PSI/SI information table, which is generated in the form of a section and a TS according to the DVB-C/MPEG II standard, and its standard fields are described in FIG. 2, Among them, vl and v2 represent different version information of corresponding standard descriptors in the DVB standard. Based on these PSI/SI information, the user terminal can parse a lot of information, such as: network operator name (Network_Name), satellite transmission (Satellite_Delivery) or cable transmission (Cable_Delivery), CA conditional reception identifier (CA_Identifier), etc. , for the end user to better use and receive, at the same time, in the PSI / SI The network operator in the generator can also develop and provide users with personalized application services based on their own operating conditions.

事件信息配置部分，主要完成节目信息以及节目本身同步播出的调度和协调，主要考虑的对象为 PSI/SI播出控制，以便于可以同步接收到电视节目、节目的对应 EPG 信息以及 PSI/SI信息。 The event information configuration part mainly completes the scheduling and coordination of the program information and the synchronous broadcast of the program itself, and the main consideration is PSI/SI broadcast control, so that the corresponding EPG information of the television program, the program, and the PSI/SI can be synchronously received. information.

数据服务协调部分，主要实现向上层提供统一的接口，以屏蔽掉不同硬件平台和配置所带来的对上层***的影响，同时将所需要传送的 EPG信息和 SI信息输送至本地播出前端进行放送。另外，该部分控制节目的播出以及节目信息的播出。 The data service coordination part mainly provides a unified interface to the upper layer to shield the impact on the upper layer system caused by different hardware platforms and configurations, and delivers the EPG information and SI information to be transmitted to the local broadcast front end. Delivery. In addition, the portion controls the broadcast of the program and the broadcast of the program information.

图 1为 EPG业务信息数据的生成***。该***是位于 EPG服务器之上的一级***，而所述 EPG服务器主要用于发布该***生成后的 EPG信息数据，图 1中的本地播出前端相当于 EPG服务器。 Figure 1 shows the generation system of EPG service information data. The system is a primary system located on the EPG server, and the EPG server is mainly used to release the EPG information data generated by the system. The local broadcast front end in FIG. 1 is equivalent to the EPG server.

在实际应用中，用户终端设备可以是家电化 PC (EPC) 或个人视频录像机（PVR) 等消费电子设备。用户终端设备要获得 EPG节目单信息时，以有线方式或是无线方式通过网络与 EPG服务器连接。目前，对于 Online EPG方式，比较常见的 EPG节目单解析方法是开发用户终端设备的应用软件在本地解析 EPG格式的数据。但现有技术中存在以下问题。 In practical applications, the user terminal device may be a consumer electronic device such as a home appliance PC (EPC) or a personal video recorder (PVR). When the user terminal device obtains the EPG program information, it connects to the EPG server through the network by wire or wirelessly. Currently, for the Online EPG mode, the more common EPG program listing method is to develop the user terminal device application software to parse the EPG format data locally. However, the following problems exist in the prior art.

1 ) 由于 EPG标准在不断地升级，其内容信息也逐步在丰富，同时第三方的有线电视运营商从业务的角度考虑，也会***一些个性化的服务信息提供给用户。这样， EPG服务器就会不断更新，而一旦 EPG服务器端的***升级，将不可避免的导致所有的用户终端设备都需要升级相应的 EPG解析部分的应用软件，如此会给用户带来极大地不便，而且造成较大的商业损失。另外，不同的 EPG提供商一般都采用自己的 EPG 标准格式，通过自己的 EPG服务器提供相应的 EPG信息，那么，在用户终端侧就需要安装与该 EPG标准格式对应的 EPG解析部分来接收和解析 EPG信息，这就存在 EPG解析部分与 EPG服务器绑定不灵活，兼容性较差的问题。 1) As the EPG standard is continuously upgraded, its content information is gradually enriched. At the same time, third-party cable TV operators will insert some personalized service information to users from the perspective of business. In this way, the EPG server will be continuously updated, and once the system of the EPG server is upgraded, it will inevitably cause all the user terminal devices to upgrade the corresponding EPG parsing part of the application software, which will bring great inconvenience to the user, and Caused a large commercial loss. In addition, different EPG providers generally use their own EPG standard format to provide corresponding EPG information through their own EPG server. Then, on the user terminal side, the EPG parsing part corresponding to the EPG standard format needs to be installed to receive and parse. EPG information, which has the problem that the EPG parsing part is inflexible and has poor compatibility with the EPG server.

2) 由于目前 EPG的标准提供商均存在对自身技术方案保护和保密的问题，如果 EPG标准格式比如 XML格式的数据在用户端设备有备份，就可能出现 EPG标准格式被破解，进而造成标准泄漏的情况，但是要实现 EPG信息的解析， EPG标准提供商又必须要将其 EPG特定的解析算法公开给第三方，如此，就使每个 EPG标准和服务提供商都面临这样两难的境地。 2) Since the current EPG standard providers have problems in protecting and keeping their own technical solutions, if the EPG standard format, such as XML format data, is backed up on the client device, the EPG standard format may be cracked, resulting in a standard leak. In the case of EPG information, EPG standard providers must disclose their EPG-specific parsing algorithms to third parties, thus making each EPG standard and service provider face such a dilemma.

作为另外一种情况，随着目前多媒体向便携式设备的发展，有很多设备已经提供了 MP3下载服务，例如：苹果公司的便携式 MP3播放器 IPod，该播放器依赖 PC端匹配的音乐终端管理软件 ITime完成从网络下载 MP3歌曲的服务。一般来说，对于不同的便携式多媒体设备，所有匹配的音乐管理软件都是通过随机附送光盘软件的方式来进行安装的，一方面成本比较高；另一方面，由于通常用户不会随身携带承载音乐管理软件的光盘，那么，一旦用户想在任意的 PC终端上随时使用该下载 MP3服务时，就会出现因为未携带需要安装的音乐管理软件而无法下载的问题。 As another case, with the development of multimedia to portable devices, many devices have been provided. The MP3 download service, for example: Apple's portable MP3 player IPod, the player relies on the PC-matched music terminal management software ITime to complete the download of MP3 songs from the network. In general, for different portable multimedia devices, all matching music management software is installed by means of the accompanying optical disc software, which is relatively expensive; on the other hand, since the user usually does not carry the music with him or her The CD of the management software, then, once the user wants to use the downloaded MP3 service at any time on any PC terminal, there is a problem that the music management software that needs to be installed cannot be downloaded.

另外，随着便携式多媒体设备的广泛应用以及用户使用需求的提高，有些用户希望在通过 MP3播放器听歌曲时或通过 MP3播放器学习英语听力时，能够边听边看到同步播放的歌词或英文听力文本，这种功能对于用户来说将是非常方便也是非常具有吸引力的。但目前只有少数多媒体终端播放器支持音乐 MP3的下载服务，而支持歌词下载业务的消费电子类多媒体设备现在还没有。发明内容 In addition, with the wide application of portable multimedia devices and the increasing user demand, some users hope to see the synchronized lyrics or English while listening to songs through an MP3 player or learning English listening through an MP3 player. Listening text, this feature will be very convenient and very attractive for the user. However, only a few multimedia terminal players support the download service of music MP3, and consumer electronic multimedia devices that support the lyrics download service are not available yet. Summary of the invention

如图 3所示，根据实施例 1的 EPG信息下载和解析的***包括： EPG信息插件，放置于 EPG服务器侧并提供给用户终端下载，用于确定是否需要更新插件以及下载并解析 EPG信息。该 EPG信息插件包括两个部分，一部分是 EPG插件下载 /更新单元，主要用于与 EPG服务器进行通信交互，以确认是否有更新的 EPG信息插件可以使用。如果有，则负责下载相应的 EPG信息插件到用户终端的指定目录，以保证当前用户终端所使用的 EPG信息插件与 EPG服务器上的版本一致。另一部分是 EPG信息下载 /解析单元，主要用于按照主动式或被动式更新的方式从 EPG服务器上下载所需要的 EPG信息，并解析所下载的 EPG信息的内容。另外，通过与终端应用单元约定的 EPG信息交互接口将解析出的 EPG信息传递给终端应用单元，以实现用户终端侧 EPG信息的更新。 As shown in FIG. 3, the system for downloading and parsing EPG information according to Embodiment 1 includes: an EPG information plug-in, placed on the EPG server side and provided to the user terminal for downloading, for determining whether the plug-in needs to be updated, and downloading and parsing the EPG information. The EPG information plugin consists of two parts, one part is the EPG plugin download/update unit, which is mainly used for communication interaction with the EPG server to confirm whether an updated EPG information plugin can be used. If so, it is responsible for downloading the corresponding EPG information plug-in to the specified directory of the user terminal to ensure that the EPG information plug-in used by the current user terminal is consistent with the version on the EPG server. The other part is the EPG information download/analysis unit, which is mainly used to download the required EPG information from the EPG server in a proactive or passive update manner, and parse the content of the downloaded EPG information. In addition, the parsed EPG information is transmitted to the terminal application unit through the EPG information interaction interface agreed with the terminal application unit, so as to implement the update of the EPG information on the user terminal side.

EPG信息下载 /解析单元还处理用户终端的注册 /登录。这里， EPG信息插件的接口满足 EPG信息插件与终端应用单元之间协商确定的交互接口协议，即相互传输的请求、响应等消息以及传输的数据符合一定的格式协议。例如，如果 EPG信息插件由一个或多个动态链接库组成，那么，终端应用单元可以通过调用的方式与 EPG信息插件进行交互，基于 EPG信息插件与终端应用单元的配合，可实现 EPG信息的传递和交付。 The EPG information download/parsing unit also processes the registration/login of the user terminal. Here, the interface of the EPG information plug-in satisfies the interactive interface protocol negotiated between the EPG information plug-in and the terminal application unit, that is, the mutual transmission request, the response, and the like, and the transmitted data conform to a certain format protocol. For example, if the EPG information plug-in is composed of one or more dynamic link libraries, the terminal application unit can interact with the EPG information plug-in by calling, and the EPG information can be transmitted based on the cooperation between the EPG information plug-in and the terminal application unit. And delivery.

在本实施例中， EPG信息插件是一个功能实体，只是接收用户终端中终端应用单元的请求，返回终端应用单元所需的信息，能够保证 EPG标准的安全可靠性，对用户是透明。一个用户终端中可以同时下载对应不同 EPG服务器的多个不同的 EPG信息插件，每个 EPG信息插件与不同的 EPG服务器一一对应。可以通过标志位来区分不同 EPG 信息插件与不同 EPG服务器的对应关系。以下仅以一个 EPG信息插件与对应的 EPG服务器进行交互，以及一个 EPG信息插件与终端应用单元进行交互为例，其它 EPG信息插件的组成与处理过程是完全相同的。 In this embodiment, the EPG information plug-in is a functional entity, which only receives the request of the terminal application unit in the user terminal, and returns the information required by the terminal application unit, thereby ensuring the security and reliability of the EPG standard and being transparent to the user. A plurality of different EPG information plugs corresponding to different EPG servers can be simultaneously downloaded in one user terminal, and each EPG information plug-in corresponds to a different EPG server. The correspondence between different EPG information plugins and different EPG servers can be distinguished by flag bits. In the following, only one EPG information plug-in interacts with the corresponding EPG server, and an EPG information plug-in interacts with the terminal application unit. The composition and processing of other EPG information plug-ins are identical.

终端应用单元设置于用户终端内部，用于接收并存储下载的 EPG信息并控制 EPG 信息的使用。终端应用单元包括： EPG信息接收单元，用于与 EPG信息插件中的 EPG 信息下载 /更新单元进行交互，提交 EPG信息下载请求，并接收解析后 EPG信息。 EPG 信息接收单元同时还负责通过检测本地注册表中的特定注册表项是否存在来判断是否有插件安装，从而确定是否需要下载 EPG信插件。另外，终端应用单元还包括电视节目接收和播放单元，用于对电视卡硬件解调出来的电视信号进行解码，以播放电视视频信号，同时实现例如延时播放等控制功能。此外，终端应用单元还包括应用功能单元，包括例如利用硬盘保护分区（HPA， Hard Disk Protected Area) 进行 EPG业务用户的用户名和密码存储管理模块、基于 EPG信息的预约录制模块等其他功能实现单元。终端应用单元可以通过网络如以太网与 EPG服务器相连，也可以与 EPG服务器直接相连。 The terminal application unit is disposed inside the user terminal for receiving and storing the downloaded EPG information and controlling the use of the EPG information. The terminal application unit includes: an EPG information receiving unit, configured to interact with an EPG information download/update unit in the EPG information plug-in, submit an EPG information download request, and receive the parsed EPG information. The EPG information receiving unit is also responsible for determining whether a plug-in is installed by detecting the presence or absence of a specific registry key in the local registry, thereby determining whether the EPG plug-in needs to be downloaded. In addition, the terminal application unit also includes a television The program receiving and playing unit is configured to decode the television signal demodulated by the television card hardware to play the television video signal, and at the same time realize a control function such as delay playing. In addition, the terminal application unit further includes an application function unit, including, for example, a user name and password storage management module of the EPG service user, a reservation recording module based on the EPG information, and the like, using a hard disk protected area (HPA). The terminal application unit can be connected to the EPG server via a network such as Ethernet, or directly to the EPG server.

用户接口（UI， User Interface ) 向用户提供使用应用程序的入口，包括用户浏览 EPG信息、更新某个频道的 EPG信息、依据 EPG信息设定预约录制任务以及进行电视节目播放控制等等。用户终端通过用户接口接收用户输入的控制命令，送至终端应用单元的应用功能单元进行处理。 The User Interface (UI, User Interface) provides users with access to the application, including user browsing EPG information, updating EPG information for a channel, setting up scheduled recording tasks based on EPG information, and controlling TV program playback. The user terminal receives the control command input by the user through the user interface, and sends the control command to the application function unit of the terminal application unit for processing.

图 4 示出了根据本发明第一实施例下载和解析电子节目指南信息的方法的流程图。如图 4所示，该方法包括以下步骤： Fig. 4 is a flow chart showing a method of downloading and parsing electronic program guide information according to the first embodiment of the present invention. As shown in Figure 4, the method includes the following steps:

步骤 40广 402: 用户终端开启并确认已与网络如以太网连接后，用户终端中的终端应用单元的 EPG信息接收单元判断本地是否已安装 EPG信息插件，如果已安装，则采用当前已安装的 EPG信息插件，并执行步骤 403; 如果未安装，则执行步骤 404。 Step 40: 402: After the user terminal is turned on and confirmed that the network is connected to the network, such as Ethernet, the EPG information receiving unit of the terminal application unit in the user terminal determines whether the EPG information plug-in is installed locally, and if it is installed, the currently installed one is used. The EPG information plugin, and step 403 is performed; if not installed, step 404 is performed.

这里，可通过检测***注册表中的特定表项（KEY ) 是否存在来判断插件是否安装。如果检测到特定表项存在，则说明已安装 EPG信息插件。否则，说明未安装 EPG 信息插件。 Here, it can be judged whether the plug-in is installed by detecting the existence of a specific entry (KEY) in the system registry. If a specific entry is detected, the EPG information plugin is installed. Otherwise, the EPG information plugin is not installed.

步骤 403: EPG信息插件的 EPG插件下载 /更新单元判断 EPG服务器是否有可用的插件需要更新。如果是，则执行步骤 404; 否则，执行步骤 408。 Step 403: The EPG plug-in download/update unit of the EPG information plug-in determines whether the EPG server has a plug-in that needs to be updated. If yes, go to step 404; otherwise, go to step 408.

'这里，判断是否需要更新 EPG信息插件是通过比较插件版本号的方式确定的，比较用户终端当前已下载的 EPG信息插件的版本号和 EPG服务器中 EPG信息插件的版本号是否相同，如果不同，则需要更新。 'Here, determine whether the EPG information plug-in needs to be updated by comparing the plug-in version number. Compare the version number of the EPG information plug-in currently downloaded by the user terminal and the version number of the EPG information plug-in in the EPG server. If they are different, Then you need to update.

步骤 404〜407：用户终端中终端应用单元的 EPG信息接收单元以例如 HTTP报文方式发送插件下载请求至 EPG服务器，并按照 EPG服务器约定的路径下载 EPG信息插件。插件下载结束后，由终端应用单元的应用功能单元控制在后台安装、运行。其中，路径可用 HTTP/URL表示。 Steps 404 to 407: The EPG information receiving unit of the terminal application unit in the user terminal transmits the plug-in download request to the EPG server in, for example, an HTTP message mode, and downloads the EPG information plug-in according to the path agreed by the EPG server. After the plug-in download is completed, the application function unit of the terminal application unit controls the installation and operation in the background. Among them, the path can be represented by HTTP/URL.

如果 EPG信息插件是第一次安装，则在 EPG信息插件安装完毕后，进入用户登录流程，并在用户登录后记录用户标识（ID) 和密码（PWD)。然后，执行步骤 411。如果 EPG信息插件不是第一次安装，则执行步骤 408。步骤 408~410: EPG信息插件的 EPG信息下载 /解析单元检查用户终端是否保存有用户 ID和 PWD，如果没有保存，说明用户未登录过，则提示用户登录到网络中，并在用户登录后记录用户 ID和 PWD，再执行步骤 411。如果已保存了用户 ID和 PWD， EPG 信息插件的 EPG信息下载 /解析单元则读取用户 ID和 PWD，以 HTTP方式将用户 ID和 PWD发送至 EPG服务器，完成后台的用户登录。 If the EPG information plug-in is installed for the first time, after the EPG information plug-in is installed, the user login process is entered, and the user identification (ID) and password (PWD) are recorded after the user logs in. Then, step 411 is performed. If the EPG information plugin is not installed for the first time, step 408 is performed. Steps 408~410: The EPG information downloading/parsing unit of the EPG information plug-in checks whether the user terminal stores the user ID and the PWD. If not, the user is not logged in, and the user is prompted to log in to the network and record after the user logs in. Step 411 is performed again with the user ID and PWD. If the user ID and PWD have been saved, the EPG information download/parsing unit of the EPG information plug-in reads the user ID and PWD, and sends the user ID and PWD to the EPG server in HTTP mode to complete the user login in the background.

这种方式可以最大程度地减小用户使用的复杂度。也就是说，对于合法用户，不需要在每次使用 EPG业务时都要求输入用户 ID和 PWD进行验证。 This approach minimizes the complexity of user usage. In other words, for legitimate users, it is not necessary to enter the user ID and PWD for verification each time the EPG service is used.

步骤 41广 412: EPG信息插件的 EPG信息下载 /解析单元将当前用户终端中 EPG信息对应的时间戳与 EPG服务器中当前可用 EPG信息对应的时间戳进行比较，并判断当前 EPG信息是否需要更新。如果需要更新，则执行步骤 413; 否则，执行步骤 417。 Step 41: 412: The EPG information downloading/parsing unit of the EPG information plug-in compares the timestamp corresponding to the EPG information in the current user terminal with the timestamp corresponding to the currently available EPG information in the EPG server, and determines whether the current EPG information needs to be updated. If an update is required, step 413 is performed; otherwise, step 417 is performed.

这里，所述时间戳用于标识 EPG信息的生成时间，如果用户终端中 EPG信息的时间戳与 EPG服务器中 EPG信息的时间戳不一致，说明用户终端中的 EPG信息已经不是最新的 EPG信息，则需要进行更新。 Here, the timestamp is used to identify the generation time of the EPG information. If the timestamp of the EPG information in the user terminal is different from the timestamp of the EPG information in the EPG server, indicating that the EPG information in the user terminal is not the latest EPG information, Need to update.

步骤 413: EPG信息插件的 EPG插件下载 /更新单元以 HTTP报文方式向 EPG服务器发送 EPG信息下载请求， EPG服务器将最新的 EPG信息用自身的 EPG标准格式发送给 EPG信息插件的 EPG插件下载 /更新单元。 EPG信息插件的 EPG插件下载 /更新单元接收并解析 EPG信息的字段内容。然后，缓存解析后的最新 EPG信息。这里所述的缓存可以通过例如在用户终端的硬盘上开辟一段存储空间暂存解析出的 EPG 信息来执行。 Step 413: The EPG plug-in download/update unit of the EPG information plug-in sends an EPG information download request to the EPG server in an HTTP message manner, and the EPG server sends the latest EPG information to the EPG plug-in of the EPG information plug-in in its own EPG standard format. Update the unit. The EPG plug-in download/update unit of the EPG information plug-in receives and parses the field contents of the EPG information. Then, cache the latest EPG information after parsing. The cache described herein can be executed, for example, by opening up a piece of storage space to temporarily parse the parsed EPG information on the hard disk of the user terminal.

步骤 414~416： EPG信息插件的 EPG插件下载 /更新单元向终端应用单元的 EPG信息接收单元发送 EPG信息更新通知， EPG信息接收单元确认 EPG信息更新通知后， EPG 插件下载 /更新单元按照双方协商的交互格式将解析后的最新的 EPG信息发送给 EPG信息接收单元， EPG信息接收单元用接收的最新 EPG信息来更新用户终端数据库中的 EPG Steps 414~416: The EPG plug-in download/update unit of the EPG information plug-in sends an EPG information update notification to the EPG information receiving unit of the terminal application unit, and after the EPG information receiving unit confirms the EPG information update notification, the EPG plug-in download/update unit negotiates according to the two parties. The interactive format sends the parsed latest EPG information to the EPG information receiving unit, and the EPG information receiving unit updates the EPG in the user terminal database with the latest EPG information received.

In息。 In interest.

步骤 417: 用户正常进行 EPG信息的应用。 Step 417: The user normally applies the EPG information.

实际上，在用户登录后， EPG信息的更新可以通过两种方式来实现，分别参见图 5和图 6。其中，图 5为主动下载 EPG信息的流程图；图 6为被动下载 EPG信息的流程图。实际上，图 4中的步骤 411a、 41广 417就是主动下载的处理过程。 In fact, after the user logs in, the update of the EPG information can be implemented in two ways, as shown in Figure 5 and Figure 6, respectively. Figure 5 is a flow chart for actively downloading EPG information; Figure 6 is a flow chart for passively downloading EPG information. In fact, steps 411a, 41 in Figure 4 are the process of active download.

如图 5所示， EPG信息主动更新的实现过程包括以下步骤： As shown in FIG. 5, the implementation process of the active update of the EPG information includes the following steps:

步骤 50广 502: EPG服务器发送 EPG信息更新广播消息；处于在线状态的用户终端，通过下载的 EPG信息插件接收到 EPG服务器的更新广播消息后，向 EPG服务器回复更新广播响应消息。 Step 50: 502: EPG server sends EPG information to update broadcast message; user end in online state After receiving the update broadcast message of the EPG server through the downloaded EPG information plugin, the EPG server replies with an update broadcast response message.

步骤 503~504： EPG信息插件比较本地 EPG信息对应的 EPG时间戳和 EPG服务器中 EPG信息对应的 EPG时间戳。如果二者不同， EPG信息插件以 HTTP报文方式向 EPG 服务器发送请求，请求下载更新的 EPG信息。 EPG服务器收到该请求后，将最新的 EPG 信息以 EPG标准格式发送给 EPG信息插件。 EPG信息插件收到更新的 EPG信息后进行解析，并将解析后的数据存储于 EPG信息插件自身的数据库中。 Steps 503~504: The EPG information plug-in compares the EPG timestamp corresponding to the local EPG information with the EPG timestamp corresponding to the EPG information in the EPG server. If the two are different, the EPG information plugin sends a request to the EPG server in HTTP message requesting to download the updated EPG information. After receiving the request, the EPG server sends the latest EPG information to the EPG information plugin in the EPG standard format. The EPG information plug-in receives the updated EPG information and parses it, and stores the parsed data in the database of the EPG information plug-in itself.

步骤 505~506： EPG信息插件向终端应用单元的 EPG信息接收单元发送 EPG信息更新通知。 EPG信息接收单元收到通知后返回响应消息，并发送确认请求，确认需要更新 EPG信息。这里，可以通过一条消息发送响应和确认请求。 Steps 505~506: The EPG information plug-in sends an EPG information update notification to the EPG information receiving unit of the terminal application unit. The EPG information receiving unit returns a response message after receiving the notification, and sends a confirmation request to confirm that the EPG information needs to be updated. Here, the response and confirmation request can be sent by a message.

步骤 507〜508： EPG信息插件调用与终端应用单元协商好的接口函数，按频道名称参数来传送每个频道对应的 EPG信息。当然，也可以以其它参数为索引传送更新的 EPG信息。终端应用单元的 EPG信息接收单元收到更新的 EPG信息后，根据频道名称参数将相应频道的 EPG信息更新到用户终端设备的本地数据库中，即更新用户终端设备本地数据库中的 EPG信息内容。 Steps 507~508: The EPG information plug-in invokes an interface function negotiated with the terminal application unit, and transmits the EPG information corresponding to each channel according to the channel name parameter. Of course, the updated EPG information can also be transmitted with other parameters as an index. After receiving the updated EPG information, the EPG information receiving unit of the terminal application unit updates the EPG information of the corresponding channel to the local database of the user terminal device according to the channel name parameter, that is, updates the EPG information content in the local database of the user terminal device.

图 6示出了 EPG信息被动更新的实现过程。该过程包括： Figure 6 shows the implementation of passive update of EPG information. The process includes:

步骤 60广 602 : 当用户输入更新命令时，例如，通过 UI 点击某一频道的 "更新 EPG "选项或是直接点击 "更新所有 EPG "选项时，终端应用单元的 EPG信息接收单元向 EPG信息插件的 EPG信息下载 /解析单元发送获取更新 EPG信息请求，该请求中包括需要更新哪些频道的 EPG信息等参数。 Step 60: 602: When the user inputs an update command, for example, by clicking the "Update EPG" option of a certain channel through the UI or directly clicking the "Update All EPG" option, the EPG information receiving unit of the terminal application unit goes to the EPG information plugin. The EPG information downloading/parsing unit sends a request for obtaining an updated EPG information, which includes parameters such as EPG information of which channels need to be updated.

步骤 603~604： EPG信息插件的 EPG信息下载 /解析单元收到获取 EPG更新信息的请求后响应该请求，并以 HTTP报文方式向 EPG服务器发送下载 EPG信.息更新请求。该请求中携带有频道名称参数、当前 EPG信息对应的 EPG时间戳。这里，频道名称、 EPG 时间戳等都属于 EPG相关信息的特征参数。 Steps 603~604: The EPG information downloading/parsing unit of the EPG information plug-in responds to the request after receiving the request for acquiring the EPG update information, and sends an EPG information update request to the EPG server in an HTTP message manner. The request carries the channel name parameter and the EPG timestamp corresponding to the current EPG information. Here, the channel name, EPG timestamp, etc. all belong to the characteristic parameters of the EPG related information.

步骤 605~608： EPG服务器根据频道名称和 EPG时间戳参数，判断该频道是否有可更新的 EPG信息。如果没有，则向 EPG信息插件返回无更新确认， EPG信息插件向终端应用单元返回无更新响应；如果有，则 EPG信息插件的 EPG信息下载 /解析单元下载并解析相应频道对应的 EPG信息。然后， EPG信息插件调用与终端应用单元协商好的接口函数，按频道名称参数来传送每个频道对应的 EPG信息给终端应用单元的 EPG 信息接收单元，终端应用单元的 EPG信息接收单元收到更新的 EPG信息后，根据频道名称参数对用户终端设备本地数据库中相应频道的 EPG信息内容进行更新。 Steps 605~608: The EPG server determines whether the channel has updateable EPG information according to the channel name and the EPG timestamp parameter. If not, the EPG information plug-in returns no update confirmation, and the EPG information plug-in returns a no-update response to the terminal application unit; if so, the EPG information download/parsing unit of the EPG information plug-in downloads and parses the EPG information corresponding to the corresponding channel. Then, the EPG information plug-in invokes an interface function negotiated with the terminal application unit, and transmits the EPG information corresponding to each channel to the EPG information receiving unit of the terminal application unit according to the channel name parameter, and the EPG information receiving unit of the terminal application unit receives the update. After the EPG information, according to the channel The name parameter updates the EPG information content of the corresponding channel in the local database of the user terminal device.

无论是主动还是被动的更新方式， EPG信息插件和用户终端的终端应用单元之间 EPG信息的通信均采用更新通知（Notification) 和响应确认（Confirmed) 的方式。 Regardless of whether it is an active or passive update method, the EPG information communication between the EPG information plug-in and the terminal application unit of the user terminal adopts a notification notification and a confirmation confirmation.

基于图 7所示的***架构，下面以播放内容服务器为歌词下载服务器，用户终端设备为 MP3播放器为例，具体说明歌词下载服务的实现过程。这里，内容数据下载服务插件为歌词下载服务插件，歌词下载服务的实现由管理单元控制歌词下载服务插件完成歌词的管理、下载、分类、检索等不同功能，根据第二实施例的内容数据下载方法的流程如图 8所示，包括以下步骤。 Based on the system architecture shown in FIG. 7, the following is to download the content server as the lyrics download server, and the user terminal device is an MP3 player as an example to specify the implementation process of the lyrics download service. Here, the content data download service plug-in is a lyrics download service plug-in, and the lyrics download service is implemented by the management unit to control the lyrics download service plug-in to complete different functions of management, download, classification, retrieval, etc. of the lyrics, and the content data download method according to the second embodiment The process shown in Figure 8 includes the following steps.

步骤 20广 202: MP3播放器启动后， MP3播放器中管理单元的设备监测单元检测并判断本地是否已安装歌词下载服务插件。如果已安装下载服务插件，则采用当前已安装的歌词下载服务插件，并执行步骤 203;如果未安装下载服务插件，则执行步骤 204。 Step 20: 202: After the MP3 player is started, the device monitoring unit of the management unit in the MP3 player detects and determines whether the lyrics download service plug-in is installed locally. If the download service plug-in is already installed, the currently installed lyrics download service plug-in is used, and step 203 is performed; if the download service plug-in is not installed, step 204 is performed.

这里，可通过检测***注册表中的特定表项（KEY) 是否存在来判断插件是否安装，具体过程与第一实施例中的相同，在此省略对其的描述。 Here, whether or not the plug-in is installed can be determined by detecting whether a specific entry (KEY) in the system registry exists, and the specific procedure is the same as that in the first embodiment, and a description thereof will be omitted herein.

步骤 203: 判断歌词下载服务器是否有可用的插件需要更新，如果是，则执行步骤 204; 否则，执行步骤 208。 Step 203: Determine whether the lyrics download server has an available plug-in that needs to be updated. If yes, execute step 204; otherwise, go to step 208.

这里，所述判断是否需要更新插件可以通过比较歌词下载服务插件版本号的方式确定，比较 MP3播放器当前己下载的歌词下载服务插件的版本号和歌词下载服务器中歌词下载服务插件的版本号是否相同，如果不同，则需要更新。 Here, the determining whether the update plugin needs to be updated may be determined by comparing the lyrics downloading the service plugin version number, comparing the version number of the lyrics download service plugin currently downloaded by the MP3 player and the version number of the lyrics download service plugin in the lyrics download server. The same, if different, you need to update.

步骤 204~207： MP3播放器中管理单元的内容更新检测单元以 HTTP报文方式发送插件下载请求至歌词下载服务器，并按照歌词下载服务器约定的路径下载歌词下载服务插件。插件下载完毕后，由管理单元的信息管理单元控制安装、运行。其中，路径可用 HTTP/URL表示。 Steps 204 to 207: The content update detecting unit of the management unit in the MP3 player sends the plug-in download request to the lyrics download server in an HTTP message manner, and downloads the lyrics download service plug-in according to the path agreed by the lyrics download server. After the plug-in is downloaded, it is controlled and installed by the information management unit of the management unit. Where the path can be represented by HTTP/URL.

如果歌词下载服务插件是第一次安装，则在歌词下载服务插件安装完毕后，进入用户登录流程，并在用户登录后记录用户标识（ID) 和密码（PWD)。然后，执行步骤 211。如果歌词下载服务插件不是第一次安装，则执行步骤 208。 If the lyrics download service plugin is installed for the first time, after the lyrics download service plugin is installed, the user login process is entered, and the user identification (ID) and password (PWD) are recorded after the user logs in. Then, step 211 is performed. If the lyrics download service plugin is not installed for the first time, then step 208 is performed.

步骤 208〜210：歌词下载服务插件的用户注册 /登录单元检查本地即 MP3播放器是否保存有用户 ID和 PWD。如果没有保存，说明用户未登录过，则提示用户登录到网络中，并在用户登录后记录用户 ID和 PWD，再执行步骤 211 ; 如果已保存，则歌词下载服务插件的用户注册 /登录单元读取用户 ID和 PWD，以 HTTP方式将用户 ID和 PWD发送至歌词下载服务器，完成后台的用户登录。 Steps 208 to 210: The user registration/login unit of the lyrics download service plug-in checks whether the local or MP3 player stores the user ID and PWD. If it is not saved, the user is not logged in, the user is prompted to log in to the network, and the user ID and PWD are recorded after the user logs in, and then step 211 is performed; if it is saved, the user registration/login unit of the lyrics download service plug-in is read. Take the user ID and PWD, send the user ID and PWD in HTTP mode. Send to the lyrics download server to complete the user login in the background.

这种方式可以最大程度的减小用户使用的复杂度。也就是说，对于合法用户，不需要在每次使用歌词下载服务时都要求输入用户 ID和 PWD进行验证。 This approach minimizes the complexity of user usage. In other words, for legitimate users, it is not necessary to enter the user ID and PWD for verification each time the lyrics download service is used.

步骤 21广 212: MP3播放器中管理单元的内容更新检测单元遍历当前本地音乐库中的歌曲，判断是否有歌曲没有相匹配的歌词，如果没有，则执行步骤 217; 否则，执行步骤 213。 Step 21: 212: The content update detecting unit of the management unit in the MP3 player traverses the songs in the current local music library to determine whether there is a song with no matching lyrics. If not, step 217 is performed; otherwise, step 213 is performed.

步骤 213: 管理单元的内容更新检测单元发送歌词搜索请求到歌词下载服务插件的内容搜索单元，以实现歌词搜索。歌词搜索请求中携带有所需下载歌词对应的歌曲名称，指示内容搜索单元按照给定的名称进行搜索且内容数据下载单元按照给定的名称下载相应的歌词。 Step 213: The content update detecting unit of the management unit sends a lyric search request to the content search unit of the lyrics download service plug-in to implement the lyric search. The lyric search request carries the song name corresponding to the desired download lyrics, instructs the content search unit to search according to the given name, and the content data downloading unit downloads the corresponding lyrics according to the given name.

步骤 21Γ216: 歌词下载服务插件的内容数据下载单元将歌曲名称参数发送给歌词下载服务器，请求下载与歌曲名称相匹配的歌词。歌词下载服务器根据歌曲名称检索与之匹配的歌词，然后将检索到的歌词以 HTTP方式发送给歌词下载服务插件的内容数据下载单元。内容数据下载单元接收歌词文件，并发送给管理单元的内容更新检测单元。内容更新检测单元根据歌词与歌曲的关联关系将下载的歌词保存到本地的歌词库中。 Step 21: 216: The content data downloading unit of the lyrics download service plug-in sends the song name parameter to the song download server, requesting to download the lyrics matching the song name. The lyrics download server retrieves the matching lyrics according to the song name, and then sends the retrieved lyrics to the content data downloading unit of the lyrics download service plug-in by HTTP. The content data downloading unit receives the lyrics file and transmits it to the content update detecting unit of the management unit. The content update detecting unit saves the downloaded lyrics to the local lyrics library according to the association relationship between the lyrics and the song.

在本地，可以建立不同的数据库分别用来存储歌曲和歌词。同时，要建立每首歌曲和歌词之间的关联关系，例如，通过歌曲名称进行关联。 Locally, different databases can be created to store songs and lyrics. At the same time, the relationship between each song and the lyrics is established, for example, by the name of the song.

步骤 217: 用户正常进行本地的 MP3播放器应用。 Step 217: The user normally performs a local MP3 player application.

同样，在用户登录后，歌词的下载如图 2所示，可以通过两种方式实现：一种是主动下载，如图 8中步骤 21广 216所示。在主动下载模式，本地管理单元依据本地音乐库的更新状态，遍历本地的音乐文件，检查哪些歌曲还没有与之相关联的歌词文件。然后，以歌曲的名称为参数，调用相应歌词下载服务插件中的接口函数，将歌曲名称参数传递给歌词下载服务器，歌词下载服务器按照该歌曲名称参数在服务器自身的歌词库中进行检索，将匹配的歌词反馈给用户终端设备上的歌词下载服务插件，歌词下载服务插件再依据约定的交互方式将所下载的歌词文件交给管理单元，管理单元按照歌词与歌曲的关联关系将该歌词进行存储。 Similarly, after the user logs in, the download of the lyrics is as shown in FIG. 2, which can be implemented in two ways: One is active download, as shown in step 21 of FIG. In the active download mode, the local management unit traverses the local music files according to the update status of the local music library, and checks which songs have not been associated with the lyrics file. Then, using the name of the song as a parameter, the interface function in the corresponding lyrics download service plug-in is called, and the song name parameter is passed to the lyrics download server, and the lyrics download server searches in the lyrics database of the server according to the song name parameter, and will match The lyrics are fed back to the lyrics download service plug-in on the user terminal device, and the lyrics download service plug-in then delivers the downloaded lyrics file to the management unit according to the agreed interaction mode, and the management unit stores the lyrics according to the association relationship between the lyrics and the song.

另一种是被动下载模式，包括两种情况。一种情况是，当用户利用用户接口输入命令，例如用户输入歌曲名称，点击 "下载歌词" 的选项时，发起歌词下载请求并完成歌词下载，如图 8中的步骤 212b以及 213~216所示；或者，用户在播放一首歌曲时，由管理单元在后台自动查找发现本地没有与该歌曲相匹配的歌词文件，此时发起歌词下载请求并完成歌词下载，如图 8中步骤 212a以及 213〜216所示。对于这两种情况，管理单元调用相关的歌词下载服务插件中的功能单元。管理单元的内容更新检测单元发送需要下载歌词的歌曲名称给歌词下载服务插件，歌词下载服务插件接收到该信息之后，向歌词下载服务器以 HTTP报文方式发送下载请求。歌词下载服务器依据该歌曲名称参数在自身的歌词库中进行检索，将匹配的歌词传递给终端设备上的歌词下载服务插件，歌词下载服务插件再依据约定的交互方式将歌词文件交给管理单元，管理单元按照歌词与歌曲的关联关系将该歌词进行存储。 The other is the passive download mode, which includes two cases. In one case, when the user inputs a command using the user interface, for example, the user inputs the song name and clicks the "download lyrics" option, the lyrics download request is initiated and the lyrics download is completed, as shown in steps 212b and 213-216 of FIG. Or, when the user plays a song, The management unit automatically finds in the background that the local lyrics file does not match the song. At this time, the lyrics download request is initiated and the lyrics download is completed, as shown in steps 212a and 213-216 of FIG. For both cases, the snap-in calls the functional unit in the relevant lyrics download service plugin. The content update detecting unit of the management unit sends the name of the song that needs to download the lyrics to the lyrics download service plug-in. After receiving the information, the lyrics download service plug-in sends the download request to the lyrics download server in the form of an HTTP message. The lyrics download server searches the lyrics library according to the song name parameter, and transmits the matched lyrics to the lyrics download service plug-in on the terminal device, and the lyrics download service plug-in delivers the lyrics file to the management unit according to the agreed interaction mode. The management unit stores the lyrics according to the association relationship between the lyrics and the song.

基于图 7所示的***结构，第二实施例的内容数据下载***同时还具备本地的音频播放和管理功能，以实现对 MP3播放器或其它便携式多媒体终端设备中音频文件的管理。为了实现管理单元与便携式多媒体终端设备的结合，以便所述多媒体终端设备在任何一个 PC终端设备上都能进行内容服务的下载，而无需利用光盘进行安装，本发明可将管理单元内嵌于便携式多媒体终端设备中，管理单元自动运行，其实现过程如图 9所示。这种情况下，管理单元可以是需要安装的应用程序，也可以直接发布成可执行程序（. exe)。程序大小完全可以依据功能的多少和界面元素的资源进行调整，可以控制在 5MB〜20MB大小之间。这对于具有 512MB以上存储空间的 MP3播放器或便携式媒体中心（PMC， Portable Media Center) 等便携式消费电子设备而言，是完全能够承受且占用的存储空间并不大。 Based on the system configuration shown in Fig. 7, the content data downloading system of the second embodiment also has local audio playback and management functions for realizing management of audio files in an MP3 player or other portable multimedia terminal device. In order to realize the combination of the management unit and the portable multimedia terminal device, so that the multimedia terminal device can download the content service on any one of the PC terminal devices without installing using the optical disk, the present invention can embed the management unit in the portable device. In the multimedia terminal device, the management unit automatically runs, and the implementation process thereof is as shown in FIG. 9. In this case, the snap-in can be an application that needs to be installed, or it can be directly published as an executable (.exe). The size of the program can be adjusted according to the number of functions and the resources of the interface elements, and can be controlled between 5MB and 20MB. For portable consumer electronic devices such as MP3 players with more than 512MB of storage space or Portable Media Center (PMC), it is completely affordable and consumes little storage space.

在实际应用中，便携式多媒体终端设备的存储介质（Flash/HDD) 中包括两部分：设备监测单元和可执行的音频管理软件，设备监测单元是一个可安装的文件，所述设备监测单元和可执行的音频管理软件的组合就相当于管理单元。那么，管理单元自动运行的实现过程包括以下步骤：便携式多媒体终端设备通过 USB接口接入 PC或其它支持 USB的设备中。以接入 PC为例， PC的操作***发现所接入的多媒体终端设备后，配置相应的设备驱动，并读取设备 ID，在 PC上显示多媒体终端设备的设备标识符；用户可以通过点击设备标识符安装多媒体终端设备存储介质中的设备监测单元到 PC 上；设备监测单元自动运行；设备监测单元检测该便携式多媒体终端设备固件中特殊字段的设备 ID字符值，如果 ID字符值符合要求，就负责调用存储于便携式多媒体终端设备上的可执行音频管理软件。音频管理软件从 PC的***中读取该多媒体终端设备的设备描述符，利用与音频管理软件相配合的歌词下载服务插件实现歌词下载服务、音频文件管理等功能。一般来说， Windows操作***完全可以实现将 USB模拟成光盘设备的自动运行，这样就无需通过设备监控单元来检测并调用音频管理软件，但由于 PC设备上所安装的操作***可能是 Windows, 也可以是 Linux或 Mac OS等其它非 Windows操作***，所以不能保证在所有的 PC设备上都可以实现 Windows情形下的自动运行，故此，在本实施例中，要求第一次通过 USB接口接入便携式多媒体终端设备时，用户需要点击*** 所发现的 USB设备名称，以安装设备监测单元，之后，该设备监测单元就可以常驻系统，负责在任何时刻检测 USB设备是否为符合其支持要求的设备，以实现调用音频管理软件，并进行歌词的下载服务。 In practical applications, the storage medium (Flash/HDD) of the portable multimedia terminal device comprises two parts: a device monitoring unit and an executable audio management software, the device monitoring unit is an installable file, the device monitoring unit and the device The combination of the implemented audio management software is equivalent to the management unit.
