Description

数字电视节目相关信息搜索方法及数字电视接收终端技术领域 Digital television program related information search method and digital television receiving terminal

本发明涉及数字电视技术，尤其涉及一种数字电视节目相关信息的搜索方法及一种数字电视接收终端。背景技术 The present invention relates to digital television technology, and more particularly to a method for searching for information related to digital television programs and a digital television receiving terminal. Background technique

数字电视与互联网络电视在全球的普及给人们的生活带来更好的视听享受。同时，电视节目数字化网络化后，除了视频及音频信号，数字电视信号中还可同时传输更多信息。 The popularity of digital TV and Internet TV has brought better audio and video enjoyment to people's lives. At the same time, after the digitalization of the television program, in addition to the video and audio signals, more information can be transmitted simultaneously in the digital television signal.

在数字电视中，所有视频、音频、文字、图片等经数字化处理后都变成了数据，并按照动态图像专家组压缩标准 2 ( MPEG-2 )打包，形成固定长度（ 188个字节）的传送包，然后将这些数据包进行复用，形成传送码流（Transport Stream, TS ) 。通常由多个节目及业务复用组成的一个 In digital TV, all video, audio, text, pictures, etc. are digitized and converted into data, and packaged according to Motion Picture Experts Group Compression Standard 2 (MPEG-2) to form a fixed length (188 bytes). The packets are transmitted, and then these packets are multiplexed to form a transport stream (Transport Stream, TS). Usually composed of multiple programs and services

TS , 每个 TS对应一个 8MHz带宽的频道。 TS, each TS corresponds to an 8MHz bandwidth channel.

数字电视接收终端为了找到需要的码流，识别不同的业务信息，在 The digital television receiving terminal identifies different service information in order to find the required code stream,

TS流中必须加入一些引导信息，为此，在 MPEG-2标准中，专门定义了程序专用信息（ Program Specific Information, PSI ) , 其作用是从一个携带多个节目的某一个 TS流中正确找到特定的节目。 Some guidance information must be added to the TS stream. For this reason, in the MPEG-2 standard, Program Specific Information (PSI) is defined, which is correctly found from a TS stream carrying multiple programs. Specific program.

在 MPEG-2标准中定义的 PSI表，是对单一 TS流的描述。由于数字电视***通常存在多个 TS流，为了引导数字电视用户能在 TS流中快速地找出自己需要的业务，数字视频广播（ Digital Video Broadcasting, DVB ) 标准对 MPEG-2的 PSI进行了扩充，在 PSI四个表的基础上再增加了九个表，形成 SI ( Service Information ) 。 SI是对整个***所有 TS流的描述，在符合 MPEG-2 标准的 TS 传输流中*** DVB 标准定义的业务信息 ( Service Information, SI ) , 使数字电视接收终端的综合接收解码器可以从 TS流中提取出节目提供商播出节目的列表和播出参数，以电子节目指南（ Electronic Program Guide, EPG )的形式显示给数字电视用户，使得用户可以方便地接收、选择数字电视节目。 The PSI table defined in the MPEG-2 standard is a description of a single TS stream. Since digital TV systems usually have multiple TS streams, in order to guide digital TV users to quickly find the services they need in the TS stream, the Digital Video Broadcasting (DVB) standard extends the PSI of MPEG-2. , added nine more based on the PSI four tables. Table, form SI (Service Information). SI is a description of all TS streams of the entire system. The service information (SI) defined by the DVB standard is inserted in the TS transport stream conforming to the MPEG-2 standard, so that the integrated receiving decoder of the digital television receiving terminal can be streamed from the TS. The list and broadcast parameters of the program broadcast program are extracted and displayed to the digital TV user in the form of an Electronic Program Guide (EPG), so that the user can conveniently receive and select the digital television program.

然而现有的 EPG只能显示节目名称、播放时间、节目截图等筒单信息，当数字电视用户想进一步了解与节目相关的其他信息时，目前的数字电视仍然无能为力。发明内容 However, the existing EPG can only display the program information such as the program name, playing time, and screenshots of the program. When the digital TV user wants to know more about other information related to the program, the current digital TV still cannot do anything. Summary of the invention

为更进一步阐述本发明为实现预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明提出的数字电视节目相关信息的搜索方法及数字电视终端的具体实施方式、结构、特征及其功效，详细说明如后。第一实施例 In order to further explain the technical means and functions of the present invention for achieving the intended purpose of the invention, the following describes the method for searching for digital television program related information and the specific implementation of the digital television terminal according to the present invention with reference to the accompanying drawings and preferred embodiments. The method, structure, characteristics and efficacy are described in detail later. First embodiment

请参阅图 1 , 其为第一实施例提供的数字电视节目相关信息的搜索方法的流程图，上述方法包括依次进行： Referring to FIG. 1, which is a flowchart of a method for searching for digital television program related information provided by the first embodiment, the method includes:

步骤 1 , 获取数字电视节目的服务信息； Step 1 : Obtain service information of the digital television program;

步骤 2、解析服务信息并生成相应的业务群关联表；步骤 3、以所述多个字段的内容为索引从互联网上获取进一步的相关信息并相应在所述业务群关联表中形成扩展字段； Step 2: parse the service information and generate a corresponding service group association table; Step 3: Obtain further related information from the Internet by using the content of the multiple fields as an index, and form an extended field in the service group association table correspondingly;

步骤 4、在业务关联表中进行检索以得到检索结果； Step 4. Perform a search in the business association table to obtain a search result;

步骤 5、以预定的格式显示检索结果给用户；以及 Step 5. Display the search result to the user in a predetermined format;

步骤 6、将检索结果分享到互联网 Step 6. Share the search results to the Internet

上述方法的执行主体例如是一个数字电视接收终端如数字电视机、数字电视机顶盒等等。 The subject of the above method is, for example, a digital television receiving terminal such as a digital television set, a digital television set top box or the like.

步骤 1中，服务信息可以是直接从数字电视信号中获取的。具体地，以现有的有线电视网络为例，其采用同轴电缆连接，传输的是高频信号。而数字电视接收终端中会包括调谐器，负责将高频信号解调成数字信号传送码流（ Transport Stream, TS ) , 而数字电视接收终端的频道解调器负责将 TS还原成数字基带信号。数字基带信号可直接经由软件根据数字视频广播（Digital Video Broadcasting, DVB ) 标准进行解析处理以得到服务信息。 In step 1, the service information may be obtained directly from the digital television signal. Specifically, taking the existing cable television network as an example, it is connected by a coaxial cable, and transmits a high frequency signal. The digital television receiving terminal may include a tuner for demodulating the high frequency signal into a digital signal transport stream (TS), and the channel demodulator of the digital television receiving terminal is responsible for restoring the TS to a digital baseband signal. The digital baseband signal can be parsed directly via software according to the Digital Video Broadcasting (DVB) standard to obtain service information.

此外，可以理解，当数字电视接收终端是基于互联网传输信号，即数字电视接收终端是互联网电视时，基于互联网的灵活性，服务信息并不限于打包在 TS中，而可以单独传送，甚至数字电视信号本身与服务信息可分别由不同的来源提供。此时，步骤 1中，根据预定的路径，直接采用互联网协议获取服务信息即可，相比于传统的有线电视网络，更加可以减少调制 /解调操作。 In addition, it can be understood that when the digital television receiving terminal transmits signals based on the Internet, that is, the digital television receiving terminal is an Internet television, based on the flexibility of the Internet, the service information is not limited to being packaged in the TS, but can be transmitted separately, or even digital television. The signal itself and the service information can be provided separately from different sources. At this time, in step 1, according to the predetermined path, the service information can be directly obtained by using the internet protocol, and the modulation/demodulation operation can be further reduced compared with the conventional cable television network.

步骤 2 中，业务群关联表内包含与所述数字电视节目相关的多个字段。上述多个字段例如可包括：节目频道号、节目类型、节目名称、节目筒介、制作单位 /公司、节目分类状态、演员信息、导演信息等。相对来说，这些字段属于较固定的内容，只要节目一旦确定，这些相关的信息也就确定。因此，这些信息适合直接嵌入数字电视的服务信息中去。然而在实际应用中，还有许多其他的相关信息，例如其他用户的最新评论，演员 /导演的最新状态等等用户想要了解。然而由于这些信息在保持更新状态，而且来源多样化，比较难于直接嵌入数字电视信号的服务信息中。 In step 2, the service group association table contains a plurality of fields related to the digital television program. The plurality of fields may include, for example, a program channel number, a program type, a program name, a program guide, a production unit/company, a program classification status, cast information, director information, and the like. Relatively speaking, these fields belong to more fixed content, and as long as the program is determined, the relevant information is determined. Therefore, this information is suitable for direct embedding in the service information of digital television. However in In practice, there are many other related information, such as the latest comments from other users, the latest status of the actor/director, etc. Users want to know. However, since the information is kept up-to-date and the sources are diversified, it is more difficult to directly embed the service information of the digital television signal.

因此，本实施例的数字电视节目相关信息的搜索方法还包括步骤 3 , 以从互联网上获取这些不易于直接嵌入数字电视信号的服务信息。步骤 3 中，例如可以采用数字电视节目名称为索引从特定的信息提供商处直接获取相关信息，或者采用数字电视节目名称为关键字在互联网上进行检索并相应抓取相关信息。 Therefore, the method for searching for digital television program related information of this embodiment further includes step 3 of obtaining service information that is not easily embedded directly into the digital television signal from the Internet. In step 3, for example, the digital television program name may be used as an index to obtain relevant information directly from a specific information provider, or the digital television program name may be used as a keyword to search on the Internet and corresponding information is captured.

步骤 3可以是由数字电视接收终端在后台自动进行，并不需要用户的干预。例如，数字电视接收终端在完成开机后，例如完成 EPG显示之后，即可在后台进行步骤 3的扩展操作。此时，扩展操作可以是针对业务群关联表内的所有条目。然而，可以理解，当前数字电视节目众多，逐一完成相对来说需要较多时间，可以优先针对用户最常观看的节目先进行步骤 3 的扩展操作，亦即，步骤 3中形成扩展字段时，针对不同的电视节目是以用户观看电视同节目的频率从高到低进行的。而用户最常观看的节目可以从用户收藏或者预订的节目单中读取。次之，还可进一步依据用户的观看统计进行预测用户可能喜欢的节目，当最常观看的节目扩展操作完成后，即可针对可能喜欢的节目进行步骤 3的扩展操作。 Step 3 can be performed automatically by the digital television receiving terminal in the background without the intervention of the user. For example, after the digital television receiving terminal completes the power-on, for example, after completing the EPG display, the expansion operation of step 3 can be performed in the background. At this point, the extension operation can be for all entries in the business group association table. However, it can be understood that there are a large number of current digital television programs, and it takes relatively time to complete one by one. The expansion operation of step 3 can be performed first for the program most frequently viewed by the user, that is, when the extended field is formed in step 3, Different TV programs are performed from high to low in frequency at which the user watches the TV and the program. The programs most frequently viewed by the user can be read from the user's favorite or booked program list. Secondly, the program that the user may like is further predicted according to the user's viewing statistics. When the most frequently viewed program expansion operation is completed, the expansion operation of step 3 can be performed for the program that may be preferred.

此外，进行步骤 3的时间并不限于在开机后。例如，在用户切换频道并保持当前频道一段时间例如 10秒后，则意味着用户 4艮可能继续保持观看当前节目，此时，可以在后台自动针对当前节目进行步骤 3的扩展操作。 In addition, the time for performing step 3 is not limited to after the power is turned on. For example, after the user switches channels and keeps the current channel for a period of time, for example, 10 seconds, it means that the user may continue to watch the current program. At this time, the extended operation of step 3 can be automatically performed for the current program in the background.

可以理解，上述进行步骤 3的时机均是出于最大程度提升用户使用体验的考虑，尽可能的使用户在想查阅相关信息时即可直接从业务群关联表中读取，而无需要再等待网络返回结果。 It can be understood that the timing of performing the above step 3 is for the purpose of maximizing the user experience, and the user can read the relevant information directly from the service group association table, without waiting for the information. The network returns the result.

扩展字段中存储的可以是直接内容或者间接内容。直接内容是指可以直接显示的内容例如文字介绍、图片、或者视频等，而间接内容是指需要进行加载或解析才能显示的内容，例如链接，链接所指向的内容需要加载之后才能进行显示。 The content stored in the extension field can be direct content or indirect content. Direct content means you can Directly displayed content such as text introduction, picture, or video, etc., and indirect content refers to content that needs to be loaded or parsed to be displayed, such as a link, and the content pointed to by the link needs to be loaded before being displayed.

当扩展字段为直接内容时，其使用方法与业务群关联表中的其他字段相同，而扩展字段为间接内容时，检索操作仍然没有变化，数字电视接收终端可得知具有相关的信息，然而，在显示时需要实时从外部数据源加载或者经过进一步的解析或者转换。步骤 4中，检索动作可以是自动进行的，或者由用户发起。例如，数字电视接收终端提供在某些条件下，如切换频道或者在 EPG中浏览频道时自动搜索并显示相关信息的选项。当这些选项被选择时，即可在条件触发时（用户切换频道或者在 EPG中浏览频道），数字电视接收终端即可以在后自动进行检索操作。由用户发起例如是指用户按下了遥控器上的某个按键。一般来说，可以采用当前节目（正在播放或者在 EPG中浏览的节目）的名称作为关键字在业务群关联表中进行检索。如果精确检索无法得到匹配结果，还可以进行模糊匹配以尽可能找到更多的相关节目的信息。 When the extension field is direct content, the usage method is the same as other fields in the service group association table, and when the extension field is indirect content, the retrieval operation remains unchanged, and the digital television receiving terminal can learn to have relevant information, however, It needs to be loaded from an external data source in real time or further parsed or converted during display. In step 4, the retrieval action may be automatic or initiated by the user. For example, a digital television receiving terminal provides an option to automatically search for and display relevant information under certain conditions, such as switching channels or browsing channels in an EPG. When these options are selected, the digital TV receiving terminal can automatically perform the retrieval operation after the condition is triggered (the user switches channels or browses the channel in the EPG). Initiating by the user, for example, means that the user has pressed a button on the remote control. In general, the name of the current program (the program being played or viewed in the EPG) can be retrieved in the business group association table using the name of the program. If the exact search does not result in a match, you can also perform a fuzzy match to find as much information about the relevant program as possible.

步骤 5中，显示检索结果可以采用预定的显示方式显示，上述显示方式例如可包括画中画（ Picture in Picture, PIP )画夕卜画（ Picture Out Picture, POP ) 或者其组合。 In step 5, the display search result may be displayed in a predetermined display manner, and the display mode may include, for example, a Picture in Picture (PIP) Picture Out Picture (POP) or a combination thereof.

具体地，如图 2所示， PIP是指在主画面 21 (当前画面）中显示一个或多个字画面 22, 在字画面中显示检索结果。检索结果可以包括直接内容或者间接内容，直接内容是指可以直接显示的内容如文字介绍、图片、或者视频等，而间接内容例如是指一个链接，只有在用户点击相应的链接后再加载相应的内容以显示。字画面 22可以在显示预定时间后自动消隐，或者在用户按下遥控器时显示 /隐藏。 Specifically, as shown in Fig. 2, PIP means that one or more word screens 22 are displayed on the main screen 21 (current screen), and the search results are displayed on the word screen. The search result may include direct content or indirect content, and the direct content refers to a content that can be directly displayed, such as a text introduction, a picture, or a video, and the indirect content refers to, for example, a link, and the corresponding content is loaded only after the user clicks the corresponding link. Content to display. The word screen 22 can be automatically blanked after a predetermined time is displayed, or displayed/hidden when the user presses the remote controller.

请参阅图 3 , POP是指在主画面 31 (当前画面）外部显示一个或多个副画面 32, 在副画面 32中显示检索结果。当采用 POP时，为了增加动感效果，还可以采用跑马灯的形式，即多个副画面 32以顺时针或者逆时针的方向滚动。 Referring to FIG. 3, POP means that one or more are displayed outside the main screen 31 (current screen). The sub-screen 32 displays the search result on the sub-screen 32. When POP is used, in order to increase the dynamic effect, a form of a marquee may be employed, that is, a plurality of sub-pictures 32 are scrolled in a clockwise or counterclockwise direction.

可以理解，上述 POP与 PIP还可以组合使用。例如，用户在观看数字电视节目时对当前节目的其他相关信息感兴趣，其可以按下遥控器上的预定按键，以 POP的形式在副画面 32a中显示多个链接（参见图 4 ) , 每个链接可以指向业务群关联表中的一个或多个字段。此时，副画面 32a 处于激活状态，用户可以采用遥控器中的方向键（上、下、左、右）切换当前激活的链接。副画面 32b用于显示副画面 32a中活动链接所指向内容的摘要、提示信息等内容。 It can be understood that the above POP and PIP can also be used in combination. For example, when watching a digital television program, the user is interested in other related information of the current program, and can press a predetermined button on the remote controller to display multiple links in the sub-screen 32a in the form of POP (see FIG. 4). Links can point to one or more fields in a business group association table. At this time, the sub-picture 32a is activated, and the user can use the direction keys (up, down, left, and right) in the remote control to switch the currently activated link. The sub-screen 32b is for displaying contents such as a digest, a cue information, and the like of the content pointed to by the active link in the sub-screen 32a.

例如在图 4中，针对最新评论的链接显示一条最新的评论，并提示确认之后会具有更多的详细内容，此时，字画面 22可以是隐藏状态。在用户按下确认键后，如图 4所示，以 PIP形式在字画面 22中显示链接 "最新评论"所指向的内容。此时，副画面仍然可以处于激活状态以方便用户在不同的链接之中切换。 For example, in Figure 4, a link to the latest comment displays a recent comment and prompts for more detailed content after confirmation, at which point the word screen 22 can be hidden. After the user presses the enter key, as shown in FIG. 4, the content pointed to by the link "newest comment" is displayed in the word screen 22 in the form of PIP. At this point, the sub-picture can still be active to allow the user to switch between different links.

此外，为了突出显示效果，在用户按下链接后，还可以采用全屏的方式显示相关信息，当然用户可以按下退出键返回按下链接之前的屏幕。或者，将相关信息作为一个图层直接叠加在当前播放的电视画面上显示。显示相关信息的图层可以是不透明或者不透明的。这种方式可以最大程度的减少对当前画面产生影响。 In addition, in order to highlight the effect, after the user presses the link, the related information can also be displayed in a full screen manner. Of course, the user can press the exit key to return to the screen before the link is pressed. Or, the related information is directly superimposed as a layer on the currently playing TV screen. The layer displaying the relevant information can be opaque or opaque. This method minimizes the impact on the current picture.

步骤 6例如可以是由用户主动发起的。分享至互联网例如可以是指将检索结果发送至专门的资源分享站以供其他用户使用，或者社交网站的个人页面中以给对此感兴趣的用户查看。还可以是将当前的节目推荐给其他用户。 Step 6 can be initiated, for example, by the user. Sharing to the Internet, for example, may refer to sending the search results to a dedicated resource sharing station for use by other users, or in a personal page of the social networking site to view the interested users. It is also possible to recommend the current program to other users.
