Background Art An ESG (Electronic Service Guide) or an electronic program guide is a multimedia broadcast service information navigation system. Through ESG information, users can learn about mobile multimedia broadcast services (including service name, play time, content and gram, price, etc.), and realize fast retrieval, preview, and access to services; it watches TV programs for users. And enjoy the information service provides a good navigation mechanism, so that users can quickly and easily find the program they care about, and view the additional information of the program.
ESG 所具备的这些功能使得其客户端成为用户观看节目的重要途径和 工具， 以致使得在 ESG上提供增值业务是十分必要的， 以便充分利用 ESG 的用户群， 为运营商创造丰厚的收入。 随着 ESG信息量的丰富，有效地组织和调度 ESG信息就成为一个比较 重要的课题。 通常， ESG待广播发送的数据信息（即， ESG广播数据）， 通过特定的 信道复用帧发送。 而用户观看的各个节目频道则一般在多个业务信道复用帧 中传送。 ESG传送的信道复用帧与业务频道的信道复用帧一般不同。 而另一方面， 为了满足终端节电， 终端接收时， 只是接收某一个指定信 道复用帧。 这样， 就需要一种更新检测方法， 在用户业务信道观看节目时， 向终端提示 ESG的更新， 以使终端可以进行相关处理。 然而目前尚未实现能 够满足终端节电特性的 ESG更新检测方法。 发明内容 考虑到相关技术中存在的上述问题而提出本发明 , 为此， 本发明旨在提 供一种移动多媒体广播电子业务指南的更新检测方法。 在该方法中，在业务复用桢的复用帧头中设置用于表示电子业务指南即 ESG是否更新的 ESG更新序号。 其中， ESG 更新序号占用四个比特的字段， 且循环使用四个比特的所 表示的比特值。 当 ESG更新时， ESG更新序号加 1。 另夕卜， 该 ESG更新序号表示基本描述表的当前更新序号。 这样， 可以通过检测业务复用帧的复用帧头中的 ESG更新序号， 来判 断 ESG是否更新。 当 ESG更新序号表示 ESG更新时，从传送 ESG数据信息的数据单元中 接收更新的 ESG数据信息， 其中， 传送 ESG数据信息的数据单元的数据单 元类型为 0。 通过本发明， 可以实现在用户观看节目过程中， 终端也能便捷地检测到 ESG的更新， 并可以进行相应的 ESG更新操作， 同时， 本发明还能满足终 端节电特性。 本发明的其它特征和优点将在随后的说明书中阐述， 并且， 部分地从说 明书中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本 发明的实施例一起用于解释本发明， 并不构成对本发明的限制。 在附图中： 图 1是根据相关技术的多媒体广播信道帧结构示意图; 图 2是根据本发明实施例的移动多媒体 ESG更新检测方法中的移动多 媒体广播复用帧头的结构示意图； 以及 图 3 是根据本发明实施例的移动多媒体广播业务复用子帧结构的示意 图。 具体实施方式 以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述 的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。 如图 1所示，移动多媒体广播的广播信道桢由若干复用帧组成。每个复 用帧又由复用帧头、 复用帧净荷、 填充部分組成。 复用帧净荷由一个或多个 复用子帧组成， 业务复用帧的复用子帧由子帧头、 视频段、 音频段、 和数据 段组成。 数据段由数据段头与多个数据单元组成， 数据段头描述了各个数据 单元的参数。其中，数据单元类型为 0时表示该数据单元传送的是 ESG数据 信息。 另外， 填充部分使用 OxFF填充。 These features of ESG make its clients an important way and tool for users to watch programs, so that it is necessary to provide value-added services on ESG in order to make full use of ESG's user base and generate rich revenue for operators. With the rich amount of ESG information, effectively organizing and scheduling ESG information has become an important issue. Generally, the data information to be broadcasted by the ESG (ie, ESG broadcast data) is transmitted through a specific channel multiplexing frame. The individual program channels viewed by the user are typically transmitted in multiple traffic channel multiplex frames. The channel multiplexed frame transmitted by the ESG is generally different from the channel multiplexed frame of the service channel. On the other hand, in order to satisfy the terminal power saving, when the terminal receives, it only receives a certain channel multiplexing frame. Thus, there is a need for an update detection method that prompts the terminal to update the ESG when the user traffic channel views the program, so that the terminal can perform related processing. However, an ESG update detection method capable of satisfying the power saving characteristics of the terminal has not been realized yet. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems in the related art, and an object of the present invention is to provide an update detecting method for a mobile multimedia broadcast electronic service guide. In this method, an ESG update sequence number indicating whether the electronic service guide, that is, the ESG is updated, is set in the multiplex frame header of the service multiplexer. The ESG update sequence number occupies a four-bit field, and the four-bit represented bit value is used cyclically. When the ESG is updated, the ESG update sequence number is incremented by 1. In addition, the ESG update sequence number indicates the current update sequence number of the basic description table. In this way, whether the ESG is updated can be determined by detecting the ESG update sequence number in the multiplex frame header of the service multiplex frame. When the ESG update sequence number indicates the ESG update, the updated ESG data information is received from the data unit transmitting the ESG data information, wherein the data unit type of the data unit transmitting the ESG data information is 0. Through the invention, the terminal can also conveniently detect the update of the ESG during the user watching the program, and can perform the corresponding ESG update operation, and at the same time, the invention can also satisfy the power saving characteristic of the terminal. Other features and advantages of the invention will be set forth in the description which follows, and The objectives and other advantages of the invention will be realized and attained by the <RTI The drawings are intended to provide a further understanding of the invention, and are intended to be a part of the description of the invention. 1 is a schematic structural diagram of a multimedia broadcast channel frame according to the related art; FIG. 2 is a schematic structural diagram of a mobile multimedia broadcast multiplexing frame header in a mobile multimedia ESG update detecting method according to an embodiment of the present invention; FIG. 3 is a schematic diagram of a structure of a mobile multimedia broadcast service multiplexing subframe according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention are described with reference to the accompanying drawings. As shown in FIG. 1, the broadcast channel of the mobile multimedia broadcast is composed of a number of multiplexed frames. Each multiplex frame is composed of a multiplexed frame header, a multiplexed frame payload, and a padding portion. The multiplexed frame payload is composed of one or more multiplexed subframes, and the multiplexed subframe of the service multiplexed frame is composed of a subframe header, a video segment, an audio segment, and a data segment. The data segment consists of a data segment header and a plurality of data units, and the data segment header describes the parameters of each data unit. Wherein, when the data unit type is 0, it indicates that the data unit transmits ESG data information. In addition, the fill portion is filled with OxFF.
ESG 广播数据和业务频道数据均通过各自业务复用帧净荷的不同类型 的复用子帧来传输。每个复用帧由 MF—ID唯一标识， MF—ID取值范围为 0 ~ 39, 其中， MF_ID 0的复用帧用于承载控制信息， 其它的复用帧用于承载 业务。 即， MF— ID― 0的复用帧， 用于承载控制信息（简称为控制复用帧）， 使用控制逻辑信道传送， 此时将一个控制信息表作为一个复用子帧； MF_ID != 0的复用帧， 用于承载业务（简称为业务复用帧）， 一个业务对应 一个复用子帧。 本发明实施例中涉及的复用系统采用基于频点、 分时复用方式。 例如， 确定 1秒钟为复用周期， 如果划分为 40份时间段（时隙：)， 则复用单元就是 25ms。 逻辑上的复用帧和时隙映射由系统配置决定。 如图 2所示， 在才艮据本发明实施例的 ESG更新检测方法中， 在业务复 用帧的复用帧头中包含 ESG更新序号， 用于表示 ESG是否更新。 其中， 该 ESG更新序号表示基本描述表的当前更新序号。 在如图 2所示的帧结构中， ESG更新序号占用四个比特的字段， 且循 环使用四个比特的所表示的比特值（即， 0000〜1111 ), 即， 在 0 ~ 15范围内 循环取值。 当 ESG更新时， 即， 当 ESG广播数据的信息发生变化时， ESG 更新序号加 1 , 例如， 如果增加到 1111 , 则重新从 0000开始取值。 不管是承载音视频的业务复用子桢，还是 ESG数据信息的复用子帧（数 据段）， 都使用该结构的复用帧头。 即携带有 ESG更新序号。 这样， 通过检 测业务复用帧的复用帧头即可判断 ESG是否更新。 另外， 图 3示出了移动多媒体广播业务复用子帧的逻辑结构。 如上所述， 业务复用帧的复用子帧由子帧头、 视频段、 音频段、 和数据 段组成。 数据段由数据段头与多个数据单元组成， 数据段头描迷了各个数据 单元的参数。其中，数据单元类型为 0时表示该数据单元传送的是 ESG数据 信息。 Both ESG broadcast data and traffic channel data are transmitted through different types of multiplex subframes of the respective service multiplexed frame payloads. Each multiplex frame is uniquely identified by the MF-ID, and the MF-ID is in the range of 0 to 39. The multiplex frame of the MF_ID 0 is used to carry control information, and the other multiplex frames are used to carry services. That is, the multiplex frame of MF_ID "0" is used to carry control information (referred to as control multiplex frame for short), and is transmitted by using a control logical channel. At this time, a control information table is used as a multiplex subframe; MF_ID != 0 The multiplexed frame is used for carrying services (referred to as service multiplexing frames), and one service corresponds to one multiplexed subframe. The multiplexing system involved in the embodiment of the present invention adopts a frequency point-based and time-division multiplexing method. For example, it is determined that 1 second is a multiplexing period, and if divided into 40 time periods (time slots:), the multiplexing unit is 25 ms. The logical multiplexing frame and time slot mapping is determined by the system configuration. As shown in FIG. 2, in the ESG update detection method according to the embodiment of the present invention, an ESG update sequence number is included in the multiplex frame header of the service multiplex frame to indicate whether the ESG is updated. The ESG update sequence number indicates the current update sequence number of the basic description table. In the frame structure shown in FIG. 2, the ESG update sequence occupies a four-bit field, and cyclically uses four bits of the represented bit value (ie, 0000 to 1111), that is, loops in the range of 0 to 15. Value. When the ESG is updated, that is, when the information of the ESG broadcast data changes, the ESG update sequence number is incremented by 1, for example, if it is increased to 1111, the value is restarted from 0000. Regardless of whether it is a service multiplexer that carries audio and video, or a multiplexed subframe (data segment) of ESG data information, the multiplexed frame header of the structure is used. That is, it carries the ESG update serial number. In this way, it can be determined whether the ESG is updated by detecting the multiplexing frame header of the service multiplexing frame. In addition, FIG. 3 shows the logical structure of a mobile multimedia broadcast service multiplex subframe. As described above, the multiplex subframe of the service multiplex frame is composed of a sub-frame header, a video segment, an audio segment, and a data segment. The data segment consists of a data segment header and a plurality of data units, and the data segment header describes the parameters of each data unit. Wherein, when the data unit type is 0, it indicates that the data unit transmits ESG data information.
ESG 广播数据和业务频道数据均通过各自业务复用帧净荷的不同类型 的复用子帧的段来传输。甚至通常业务频道与 ESG数据信息传输使用的是不 同的复用子帧、 复用帧。 这样， 当通过检测业务复用帧的复用帧头判断 ESG更新时， 则可以从 数据单元类型为 0的数据单元接收更新的 ESG数据信息。 换言之， 当用户观看节目时， 通过该节目音视频数据段、 其所归属复用 子帧、 其所归属的复用帧的帧头， 检测其中的 ESG更新序号， 即可实现节目 观看中的 ESG数据信息的更新。 这样就避免了终端需要更多时间进行调谐接收、解复用器开启 , 以接收 解析 ESG数据信息来检测 ESG数据的更新， 满足了终端的节电特性。 如上所述， 通过本发明提供的在移动多媒体广播系统中的 ESG的更新 监测方法， 即使在用户观看节目过程中， 也可以使得终端能便捷地检测到 ESG的更新， 并可以进行相应的 ESG更新操作， 同时也满足了终端节电特 性。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明，对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。 Both ESG broadcast data and traffic channel data are transmitted through segments of different types of multiplex subframes of the respective service multiplexed frame payloads. Even the usual service channel and ESG data information transmission use different multiplex subframes and multiplex frames. Thus, when the ESG update is judged by detecting the multiplex frame header of the service multiplex frame, the updated ESG data information can be received from the data unit of the data unit type 0. In other words, when the user views the program, the ESG update sequence number is detected by the program audio and video data segment, the multiplex subframe to which it belongs, and the frame header of the multiplex frame to which it belongs, so that the ESG in the program viewing can be realized. Update of data information. This avoids that the terminal needs more time for tuning reception and demultiplexer to receive the parsed ESG data information to detect the update of the ESG data, and meets the power saving characteristics of the terminal. As described above, the update monitoring method of the ESG in the mobile multimedia broadcast system provided by the present invention enables the terminal to conveniently detect the update of the ESG and perform the corresponding ESG update even during the user watching the program. The operation also satisfies the terminal power saving characteristics. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
