步骤 46, 媒体服务器将生成的控制指令发送给流媒体服务器； 步骤 47, 流媒体服务器根据接收到的控制指令对该移动流媒体节目进 行相应控制。
其中， 用户也可以使用 3G移动终端将按键信息发送给媒体服务器， 然 后再由媒体服务器转发给业务服务器； 控制指令也可以由媒体服务器生成， 即业务服务器将查找到的控制信息发送给媒体服务器， 媒体服务器再根据 接收到的控制信息生成相应的控制指令， 然后将生成的控制指令发送给流 媒体服务器。
若上述控制移动流媒体节目播放的装置为媒体服务器， 则本发明实施 例二中， 在 3G系统中控制移动流媒体节目播放的方法具体实现流程如图 5 所示， 其具体处理过程如下：
步骤 51 , 业务 Λ良务器定义按键信息和控制信息的对应关系， 并将定义 的对应关系发送给媒体服务器；
步骤 52, 用户在通过 3G移动终端收看移动流媒体节目时， 若需要对 移动流媒体节目进行控制， 则使用 3G移动终端， 通过视频接入网关向媒体 服务器发送按键信息；
步骤 53 , 媒体服务器根据接收到的按键信息， 在存储的按键信息和控 制信息的对应关系中， 查找对应的控制信息；
步骤 54, 媒体服务器根据查找到的控制信息， 生成对应的控制指令； 步骤 55 , 媒体服务器将生成的控制指令发送给流媒体服务器； 步骤 56, 流媒体服务器根据接收到的控制指令对该移动流媒体节目进 行相应控制。 若上述控制移动流媒体节目播放的装置为专用于对移动流媒体节目进 行控制的控制服务器， 则本发明实施例三中， 在 3G系统中控制移动流媒体 节目播放的方法具体实现流程如图 6所示， 其具体处理过程如下：
步骤 61 , 业务 Λ良务器定义按键信息和控制信息的对应关系， 并将定义 的对应关系发送给控制服务器；
步骤 62, 用户在通过 3G移动终端收看移动流媒体节目时， 若需要对 移动流媒体节目进行控制， 则使用 3G移动终端， 通过视频接入网关向控制 服务器发送按键信息；
步骤 63 , 控制服务器根据接收到的按键信息， 在存储的按键信息和控 制信息的对应关系中， 查找对应的控制信息；
步骤 64, 控制服务器根据查找到的控制信息， 生成对应的控制指令； 步骤 65 , 控制服务器将生成的控制指令发送给媒体服务器；
步骤 66, 媒体服务器将生成的控制指令发送给流媒体服务器； 步骤 67, 流媒体服务器根据接收到的控制指令对该移动流媒体节目进 行相应控制。
其中，用户也可以使用 3G移动终端将按键信息发送给媒体服务器或业 务服务器， 然后再由媒体服务器或业务服务器转发给控制服务器； 控制指 令也可以由媒体服务器生成， 即控制服务器将查找到的控制信息发送给媒 体服务器， 媒体服务器再根据接收到的控制信息生成相应的控制指令， 然 后将生成的控制指令发送给流媒体服务器。 本发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权 利要求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在 内。
