具体实施方式detailed description

应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

本发明的核心思想为通过节目标识字符串以标识电子节目菜单EPG中同一个系列节目中的每一集，从而达到准确完整的自动预约录制同一个系列节目的目的。本发明的核心思想适用于任何具有EPG的终端设备的节目录制，本发明具体以数字电视机进行举例。The core idea of the present invention is to identify each of the same series of programs in the electronic program menu EPG by the program identification string, thereby achieving the purpose of accurately and completely recording the same series of automatic reservations. The core idea of the present invention is applicable to program recording of any terminal device having an EPG, and the present invention is specifically exemplified by a digital television set.

参照图1，图1为数字电视机节目录制流程示例图。数字电视机包括节目接收装置2、EPG数据库3和节目录制装置4。其中，节目接收装置2用于接收并解析广播端1发送过来的节目信息；EPG数据库3用于保存节目接收装置2解析的节目信息；节目录制装置4用于从EPG数据库3中获取节目信息以及进行节目的预约录制。Referring to FIG. 1, FIG. 1 is a diagram showing an example of a digital television program recording process. The digital television set includes a program receiving device 2, an EPG database 3, and a program recording device 4. The program receiving device 2 is configured to receive and parse program information transmitted by the broadcast terminal 1; the EPG database 3 is configured to store program information parsed by the program receiving device 2; and the program recording device 4 is configured to acquire program information from the EPG database 3 and Make an appointment recording of the program.

在数字电视***中，EIT表（Event Information Table，事件信息表）携带每个节目的基本信息，例如节目名称、开始时间、持续时间等，EIT表中可以嵌入一些描述符来携带更多的节目信息。CID（content identifier descriptor，内容描述符）是一种允许使用者自定义类型，并且也允许嵌入到EIT表中。CID描述符内容分为cid type和cid string两部分，本发明将cid type设定为一个固定数值，例如0x21，来表示其后跟随的cid string为标识系列节目的字符串，这个cid type是必须的，因为其他用途的CID描述符也可能被***到EIT表中。通过查找设定cid type，从而可以获取标识系列节目的字符串。本发明就是利用CID描述符的特点，令其携带自定义类型的字符串并关联到相应的节目表中，以此来标识一个系列节目中的每一集，从而达到准确完整预约录制一个系列节目的目的。cid string的规则定义为series+ series event name+series event number+episode number，例如要标识《brave heart》电视剧第一集，按照cid string的规则为series.brave heart.12345.1，一个系列节目的每一集都携带相同规则的CID描述符，只是集数不同，这样每个系列节目就具有唯一性的标识字符串。In the digital TV system, the EIT table (Event Information Table, event information table) carries basic information of each program, such as program name, start time, duration, etc., and some descriptors can be embedded in the EIT table to carry more program information. CID (content The identifier descriptor (content descriptor) is a type that allows the user to customize the type and also allows embedding into the EIT table. CID descriptor content is divided into cid type and cid Two parts of the string, the present invention sets the cid type to a fixed value, such as 0x21, to indicate that the cid string that follows is a string identifying the series, this cid Type is required because CID descriptors for other purposes may also be inserted into the EIT table. Set cid by looking up Type, which allows you to get a string that identifies the series. The invention utilizes the characteristics of the CID descriptor, so that it carries a string of a custom type and is associated with the corresponding program list, thereby identifying each episode of a series of programs, thereby achieving accurate and complete reservation recording of a series of programs. the goal of. Cid The rule for string is defined as series+ series event name+series event number+episode Number, for example to identify the first episode of "brave heart" TV series, follow the rules of cid string for series.brave Heart.12345.1, each episode of a series of programs carries the same rule CID descriptor, but the set number is different, so each series has a unique identification string.

广播端1在打包传输流的EPG信息时，需要按照上述规则将CID描述符打包到EIT表中，从而数字电视的节目接收装置2通过解析EIT表来提取EPG信息，在解析出节目基本信息的同时，也要提取出标识系列节目的CID描述符。然后根据前面定义的cid type值将标识系列节目的CID区分出来，而标识系列节目的字符串就在cid string之后的域中。最后将得到标识系列节目的字符串后与其他基本信息一起存储到EPG数据库3中。节目录制装置4从EPG数据库3中获取节目信息后即可进行系列节目的预约与录制。When the broadcast end 1 packs the EPG information of the transport stream, the CID descriptor needs to be packaged into the EIT table according to the above rules, so that the program receiving apparatus 2 of the digital television extracts the EPG information by parsing the EIT table, and parses the basic information of the program. At the same time, the CID descriptor of the identification series program is also extracted. Then according to the cid defined earlier The type value distinguishes the CID identifying the series, and the string identifying the series is in cid The domain after the string. Finally, the character string identifying the series program will be stored in the EPG database 3 together with other basic information. The program recording device 4 can acquire and record a series of programs after acquiring the program information from the EPG database 3.

参照图2，图2为本发明节目录制方法第一实施例的流程示意图。本实施例中本发明节目录制方法包括：Referring to FIG. 2, FIG. 2 is a schematic flowchart of a first embodiment of a program recording method according to the present invention. The program recording method of the present invention in this embodiment includes:

步骤S10，获取预约节目指令，所述预约节目指令包括节目信息；Step S10, acquiring a reserved program instruction, where the reserved program instruction includes program information;

预约节目指令为用户录制节目前设定，所述预约节目指令包括节目信息，例如节目名称、节目开始时间、节目结束时间等。The reserved program command is set before the user records the program, and the reserved program command includes program information such as a program name, a program start time, a program end time, and the like.

步骤S20，根据所述预约节目指令，从所述电子节目菜单EPG数据库中获取与所述节目信息匹配的EPG信息，并从该匹配的EPG信息中获取所述预约节目的节目标识字符串；Step S20, acquiring EPG information matching the program information from the electronic program menu EPG database according to the reserved program instruction, and acquiring a program identification character string of the reserved program from the matched EPG information;

在数字电视***中，为了能有效地从众多的数据包中定位查找信息，而使用了很多的标识。如ON ID（Original_network_id，原始网络标识）、TS ID（Transport_stream_id，传输流标识）、Service ID (业务标识)、Event ID (事件标识)。预约节目时会得到ON ID，TS ID，Service ID，Event ID等标识信息以标识一个唯一的节目，从而通过这些标识信息，可以到EPG数据库中提取该节目的EPG信息。所述EPG信息包括节目名称、节目开始时间、节目结束时间、节目频道、节目类型、节目简介以及节目标识字符串等。同时也可以进一步从该节目的EPG信息中获取到该节目的节目标识字符串。例如，用户预约的节目为《Prison Break》整个连续剧，同时根据预约节目指令从EPG数据库中获取某一频道《Prison Break》的EPG信息，所述《Prison Break》的EPG信息中包含有该节目的节目标识字符串，例如该EPG信息中播放的《Prison Break》为第三集，则其节目标识字符串为：series.Prison Break.0112.3。节目标识字符串具体规则以实际数字电视***中的为准，此处仅用于解释。In the digital television system, in order to effectively locate the search information from a plurality of data packets, a lot of logos are used. Such as ON ID (Original_network_id, original network ID), TS ID (Transport_stream_id, transport stream ID), Service ID (Business ID), Event ID (Event ID). When you reserve a program, you will get an ON ID, TS ID, Service ID, Event. The ID and the like identify information to identify a unique program, so that the EPG information of the program can be extracted into the EPG database through the identification information. The EPG information includes a program name, a program start time, a program end time, a program channel, a program type, a program profile, and a program identification string. At the same time, the program identification string of the program can be further obtained from the EPG information of the program. For example, the program reserved by the user is "Prison" Break" the whole series, and at the same time, obtain EPG information of a channel "Prison Break" from the EPG database according to the reserved program instruction, said "Prison" The EPG information of Break contains the program identification string of the program, for example, "Prison" played in the EPG information. Break is the third episode, and its program identification string is: series.Prison Break.0112.3. The specific rules of the program identification string are based on the actual digital television system and are used here for explanation only.

步骤S30，根据所述预约节目的节目标识字符串，从所述EPG数据库中获取与所述预约节目的节目标识字符串匹配的节目信息；Step S30: Obtain, according to the program identification string of the reserved program, program information that matches the program identification string of the reserved program from the EPG database;

录制同一系列节目的其他集数，需要先获取其他集数的节目标识字符串信息。根据步骤S20中获取到的该系列节目的节目标识字符串，在EPG数据库中查找其他频道中同该节目的节目标识字符串匹配的节目信息。获取具有同该节目的节目标识字符串匹配的节目信息。例如，预约节目的节目标识字符串为series.Prison Break.0112.3，则可以将预约节目的节目标识字符串中相同部分字符串作为查找条件，例如以“series.Prison Break”或者“series.Prison Break.0112”作为匹配查找条件，通过查找EPG数据库，得到与预约节目的节目标识字符串为series.Prison Break.0112.3匹配的其他节目标识字符串为series.Prison Break.0112.6，则获取节目标识字符串为series.Prison Break.0112.6的节目信息。节目标识字符串具体规则以实际数字电视***中的为准，此处仅用于解释。To record the other episodes of the same series, you need to obtain the program identification string information of other episodes. According to the program identification string of the series of programs acquired in step S20, the program information matching the program identification string of the program in other channels is searched in the EPG database. Program information having a program identification string matching the program is obtained. For example, the program identification string of the reserved program is series.Prison Break.0112.3, you can use the same part of the string in the program identification string of the reserved program as the search condition, for example, "series.Prison" Break" or "series.Prison Break.0112" as a matching search condition, by looking up the EPG database, the program identification string obtained with the reserved program is series.Prison The other program identification string matched by Break.0112.3 is series.Prison Break.0112.6, then the program identification string is series.Prison Program information of Break.0112.6. The specific rules of the program identification string are based on the actual digital television system and are used here for explanation only.

由于不同频道的节目信息并不统一，各频道之间可能会播放相同的节目，或者在同一时间播放同一系列节目，因此，需要对获取到同一系列节目的节目信息进行筛选。新添加到预约录制列表中的节目信息不能同原有录制列表中的节目信息冲突，所述录制冲突包括录制时间冲突和录制内容冲突。例如，原有录制列表中的节目录制时间为7：00~9:00，则新添加的节目信息不能在7：00~9:00之间进行录制，也即同一时间只能录制一个节目。不过，如果录制设备的硬件可以实现多个节目的同时录制，则不存在录制时间的冲突。因此，对于节目录制筛选规则的确定，具体可以参照录制设备而定。在本实施例中，录制设备优选为同一时间只能录制一个节目。录制内容冲突是指同样的节目内容只需录制一次，具体情况可以根据用户需求而设置，本实施例优选为同样的节目内容只录制一次。Since the program information of different channels is not uniform, the same program may be played between the channels, or the same series of programs may be played at the same time. Therefore, it is necessary to filter the program information of the same series of programs. The program information newly added to the reserved recording list cannot collide with the program information in the original recording list, and the recording conflict includes a recording time conflict and a recording content conflict. For example, if the program recording time in the original recording list is from 7:00 to 9:00, the newly added program information cannot be recorded between 7:00 and 9:00, that is, only one program can be recorded at the same time. However, if the hardware of the recording device can simultaneously record multiple programs, there is no conflict in recording time. Therefore, the determination of the program recording screening rule can be specifically determined by referring to the recording device. In this embodiment, the recording device preferably only records one program at a time. The recording content conflict means that the same program content only needs to be recorded once, and the specific situation can be set according to the user's needs. In this embodiment, the same program content is preferably recorded only once.

步骤S402，当获取到的与所述预约节目的节目标识字符串匹配的节目信息同所述预约录制列表中的节目信息不存在录制冲突时，判断获取到的与所述预约节目的节目标识字符串匹配的节目信息是否存在至少两个；Step S402, when the obtained program information matching the program identification string of the reserved program does not have a recording conflict with the program information in the reserved recording list, determining the acquired program identification character of the reserved program. Whether there are at least two pieces of program information matched by the string;

当所匹配的节目信息同所述预约录制列表中的节目信息不存在录制冲突时，判断所匹配的节目信息是否存在至少两个。如果在不存在录制冲突的前提下，仍然具有多个符合条件的节目信息，则对各节目再做进一步地筛选。When there is no recording conflict between the matched program information and the program information in the reserved recording list, it is determined whether there are at least two matching program information. If there are still multiple eligible program information in the absence of a recording conflict, then each program is further filtered.

步骤S403，当获取到的与所述预约节目的节目标识字符串匹配的节目信息存在至少两个时，将获取到的与所述预约节目的节目标识字符串匹配的节目信息中播放起始时间最早的节目信息添加到所述预约录制列表。Step S403, when there are at least two pieces of program information that match the program identification string of the reserved program, the playback start time of the acquired program information matching the program identification string of the reserved program The earliest program information is added to the reserved recording list.

进一步筛选的规则可以由用户选择设定，也可以由数字电视机默认设定。例如按画质、播放时间、频道等进行进一步地筛选。本实施例中优选播放时间最早的节目信息作为进一步地筛选条件。The rules for further screening can be set by the user or set by default on the digital TV. For example, further screening is performed according to image quality, play time, channel, and the like. In the present embodiment, the program information with the earliest playback time is preferred as a further screening condition.

本实施例中，通过对获取到的同一系列节目的其他节目信息进行筛选，将符合录制要求的节目信息添加到预约录制列表中，从而剔除了对节目录制产生影响的节目信息，例如重复录制、时间冲突等，同时，进一步地优选出播放时间最早的节目，提高整个预约录制的录制效率。In this embodiment, by filtering other acquired program information of the same series of programs, the program information meeting the recording requirement is added to the reserved recording list, thereby eliminating program information that affects the recording of the program, such as repeated recording, Time conflicts and the like, and at the same time, the program with the earliest playing time is further optimized, and the recording efficiency of the entire scheduled recording is improved.
