Description

一种手机电视业务数据的传输及接收方法
技术领域
本发明涉及手机电视领域， 尤其涉及一种手机电视业务数据的传输及接 收方法。
背景技术
手机电视（移动多媒体广播 )技术和标准发展迅速， 例如欧洲的 DVB-H ( Digital Video Broadcast Handheld, 数字视频广播手持式接收） 、 美国的 MediaFLO ( Media Forward Link Only, 媒体单一前向链路 )和中国的 CMMB ( China Mobile Multimedia Broadcasting , 中国移动多媒体广播 )等。
对于手机上的任何功能， 手机的功耗都是一种紧约束。 不论何种制式的 手机电视， 在研发之初都要解决手机的功耗问题。 如 CMMB和 DVB-H都釆 用了分时隙（time-slicing )技术来降低手机的功耗。 分时隙技术把物理信道按 时序分成若干时隙， 不同节目的数据单独打包， 在指定的时隙上发射。 用户 选择观看某个节目时，手机的收发信机实际上处于非连续接收（Discontinuous RX , DRX )状态， 也就是说， 收发信机只在用户选择的节目所占用的时隙 进行接收即可， 在其它时隙可以不工作， 从而大大减少了收发信机的功耗。
手机电视以业务（Service ) 为单位组织数据。 手机电视的业务用于承载 电视节目和下载数据， 电视节目通常包含音频和视频两个部分。 手机电视的 发送端在发送业务数据时， 通常是将一个节目的所有数据 (包括音频数据、 视频数据和同步信息）封装在一个数据包中， 按照既定策略为这个数据包分 配时隙， 进行发送。 用户收看节目时， 终端接收数据包， 解析出音频数据、 视频数据以及同步信息， 进行播放。
实际使用中， 用户通常是利用一些零散的时间观看手机电视， 例如在行 驶中的车辆上。 这些环境或者比较颠簸， 或者比较嘈杂， 并不适合用户同时 消费节目的音频部分和视频部分， 用户可能会选择只收听节目的音频部分关 闭视频部分， 或只观看节目的视频部分关闭音频部分。 但是， 在现有技术中， 即使用户选择只播放节目的音频部分或者只播放 视频部分， 相应地关闭节目的视频部分或音频部分， 由于解析的需要， 终端 还是要接收业务数据的整个数据包， 其中也就包括了用户实际上并不需要的 一部分数据， 以至于造成终端不必要的功率损耗。 发明内容
本发明要解决的技术问题是提供一种手机电视业务数据的传输及接收方 法， 实现用户在选择仅播放节目的音频部分或视频部分时， 终端仅需相应地 接收节目的音频部分或视频部分， 以减少功耗。
为解决上述技术问题， 本发明的一种手机电视业务数据的传输方法， 将 手机电视节目的音频部分和视频部分分拆为音频子业务和视频子业务， 在发 送手机电视节目的业务数据时， 发送端将业务数据分为音频子业务数据和视 频子业务数据； 发送端在不同的传输资源上对音频子业务数据和视频子业务 数据分别进行发送， 并将音频子业务和视频子业务的关联关系信息发送给终 端。
进一步地， 终端接收节目的业务数据时， 若用户选择仅收听音频或仅观 看视频， 则终端根据所接收到的关联关系信息， 仅接收音频子业务数据或视 频子业务数据； 若用户选择音视频同时播放， 则终端根据所接收到的关联关 系信息， 对音频子业务数据和视频子业务数据均进行接收。
进一步地， 发送端在对音频子业务数据和视频子业务数据分别进行发送 前， 还将音频子业务和视频子业务的传输资源信息发送给终端， 终端根据传 输资源信息对音频子业务数据和 /或视频子业务数据进行接收。

匕。 附图概述
图 1为本发明的手机电视业务数据的传输方法的流程图；
图 2为本发明实施例的流程图。
本发明的较佳实施方式
本发明通过将一节目 （分拆节目） 的音频部分和视频部分分为两个独立 的子业务， 即： 音频子业务和视频子业务， 选择在不同的传输资源上分别发 送两个子业务的数据， 并将音频子业务和视频子业务的分拆信息通知终端， 分拆信息包括： 关联关系信息和传输资源信息。
当用户选择仅播放节目的音频部分或视频部分时， 终端可以仅相应地接 收音频子业务或视频子业务的数据， 并完成播放； 当用户选择对节目进行正 常播放时， 终端对音频子业务和视频子业务的数据均进行接收， 并同步播放 节目的音频部分和视频部分。 下面结合附图对本发明的具体实施方式进行说明：
图 1所示为本发明的手机电视业务数据的传输方法， 包括如下步骤：
101 : 在发送端， ESGVEPG服务器生成 ESGVEPG时， 在 ESGVEPG中包 含分拆节目的关联关系信息， 并对 ESGVEPG进行发送；
关联关系信息可以釆用分离式声明或复合式声明， 分离式声明是指在 ESGVEPG中分别包含音频子业务和视频子业务的指南信息， 在音频子业务的 指南信息中标明其音频属性及与其关联的视频子业务； 在视频子业务的指南 信息中标明其视频属性及与其关联的音频子业务。 在音频子业务和视频子业 务的指南信息中还分别包含在对音频子业务与视频子业务进行同步播放时所 需的同步信息。
复合式声明是指在 ESGVEPG中仅包含一个复合的指南信息，在该复合的 指南信息中标明该节目是否为分拆节目， 如果为分拆节目， 还包含音频子业 务和视频子业务的业务 ID等信息标识关联关系。在复合的指南信息中同样需 要包含在对音频子业务与视频子业务进行同步播放时所需的同步信息。
102:发送端的复用器为分拆节目的音频子业务和视频子业务分配不同的 传输资源， 并将音频子业务和视频子业务的传输资源信息下发给终端；
例如， CMMB 中上述传输资源包括业务所对应的复用帧和发送时隙， DVB-H中包括发送时隙等。
103:发送端的手机电视服务器将分拆节目的业务数据分成音频子业务数 据和视频子业务数据， 并分别将音频子业务数据和视频子业务数据发送给复 用器；
104: 复用器将接收到的音频子业务数据和视频子业务数据分别进行封 装， 并釆用各自的传输资源发射到空中；
105: 终端接收到 ESGVEPG后， 对 ESGVEPG进行存储， 对关联关系信息 进行解析， 对于分拆节目， 允许用户选择仅收听音频、 仅观看视频和音视频 同时播放；
106: 用户选择收看分拆节目， 如果选择仅观看视频， 则终端根据视频子 业务的传输资源信息， 配置收发信机和软件模块， 仅对视频子业务数据进行 接收并播放；
107: 如果选择仅收听音频， 则终端才艮据音频子业务的传输资源信息， 配 置收发信机和软件模块， 仅对音频子业务数据进行接收并播放；
108: 如果选择音视频同时播放， 则终端根据音频子业务和视频子业务的 传输资源信息， 配置收发信机和软件模块， 对视频子业务数据和音频子业务 数据均进行接收并根据同步信息进行同步播放。
对于分拆节目， 在音视频同时播放的情况下， 如果用户进行如静音或关 闭视频等切换操作， 则终端根据用户的选择， 配置收发信机和软件模块执行 仅接收音频子业务数据或视频子业务数据并进行播放。
下面以在 CMMB中实现本发明为实施例，进一步说明本发明的方法， 图 2所示为本发明在 CMMB中的手机电视业务数据的传输方法， 以对业务 ID ( SID )为 601的节目进行分拆为例， 包括如下步骤：
201 : ESG服务器在 SID为 601的节目的指南信息中包含关联关系信息， 关联关系信息中包含指示该节目是否为分拆节目的标识， 如果为分拆节目， 还包含音频子业务的 SID和视频子业务的 SID, ESG服务器将 ESG发送给复 用器， 复用器将 ESG封装到复用帧中发送给调制器， 调制器将封装 ESG的 复用帧调制为电磁波， 通过发射设备发射到空中；
本实施例中关联关系信息釆用复合式声明。
在 SID为 601的节目的 ESG XML中增加业务分拆指示（ splitted )字段， 标识该节目是否为分拆节目； 增加音频子业务 ID ( AudioSID )字段， 标识音 频子业务的 SID; 增加视频子业务 ID ( VideoSID )字段， 标识视频子业务的 SID。
本实施例中， 将 splitted字段的值设置为 "true" , 标识该节目为分拆节 目， 且通过将 AudioSID字段的值设置为 6011 , 将 VideoSID字段的值设置为 6012, 分别标识音频子业务的 SID为 6011 , 视频子业务的 SID为 6012, 以及 SID为 6011的音频子业务与 SID为 6012的视频子业务具有关联关系。 202: 复用器为音频子业务和视频子业务分配资源， 在持续业务复用配置 ( CMCT )表中分别记录音频子业务和视频子业务的发送时隙信息， 并通过 调制器将 CMCT发射到空中；
假设现有技术中 SID为 601的节目占用一个复用帧中的一个复用子帧， 在时隙 3、 4、 5、 6上发送； 本实施例中， 设复用器为 SID为 6011的音频子 业务分配的资源为占用复用帧 2的复用子帧 1 , 在时隙 3上发送； 为 SID为 6012的视频子业务分配的资源为占用复用帧 3的复用子帧 1 , 在时隙 4、 5、 6上发送。 由于视频子业务数据较大， 所以占用的带宽较大。
203:手机电视服务器将 SID为 601的节目的业务数据分成音频子业务数 据和视频子业务数据， 并分别将音频子业务数据和视频子业务数据发送给复 用器；
204:复用器将接收到的音频子业务数据封装到复用帧 2的复用子帧 1的 音频段中， 将接收到的视频子业务数据封装到复用帧 3的复用子帧 1的视频 段中， 并将复用帧 2和复用帧 3发送给调制器；
205: 调制器将复用帧 2和复用帧 3调制为电磁波， 并分别在时隙 3和时 隙 4、 5、 6上发射到空中；
206: 用户选择使用手机电视时， 终端接收 CMCT表， 对 CMCT表进行 存储；
CMCT表中不仅记录有各个业务占用的时隙资源， 还记录有各个业务的 解码参数。
207: 终端接收 ESG, 对 ESG进行存储；
ESG中除包含关联关系信息外， 还包含一部分播放器配置参数。
208: 终端对 ESG中包含的关联关系信息进行解析， 对于分拆节目， 允 许用户选择仅收听音频、 仅观看视频和音视频同时播放；
209: 当用户选择对一个分拆的节目仅收听音频或仅观看视频时， 终端根 据用户选择的音频子业务或视频子业务的 SID, 从 CMCT表中查找该音频子 业务或视频子业务对应的发送时隙信息；
210: 终端根据查找到的音频子业务或视频子业务的发送时隙信息， 配置 收发信机和软件模块， 接收指定时隙的音频子业务数据或视频子业务的电磁 信号， 将电磁信号解调为复用帧， 对复用帧进行解复用， 解析出音频子业务 数据或视频子业务数据；
211 : 终端根据 ESG中的播放器配置参数和解码参数， 配置播放器， 对 音频子业务或视频子业务数据进行播放；
212: 如果用户选择音视频同时播放， 则终端根据音频子业务和视频子业 务的 SID, 从 CMCT表中查找音频子业务和视频子业务的发送时隙信息， 配 置收发信机和软件模块接收音频子业务和视频子业务的电磁信号， 将电磁信 号解调为复用帧， 对复用帧进行解复用， 解析出音频子业务数据和视频子业 务数据；
213: 终端根据 ESG中的播放器配置参数和业务的解码参数配置播放器， 对音频子业务和视频子业务的数据进行播放；
如果用户选择仅收听音频或仅观看视频， 在播放过程中， 需要进行自同 步； 如果用户选择音视频同时播放， 则还需要根据 ESG中携带的同步信息完 成音频子业务与视频子业务的同步。
显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或 者将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软 件结合。
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。
