请参阅图 1 , 本发明实施例的 IPTV节目搜索方法包括以下步骤： 步骤 1: 用户输入影片中的一段台词， 其中， 用户通过语音识别技 术输入影片台词或遥控器、 键盘等设备输入影片台词；
步骤 2: 用户终端设备将接收到的台词通过网络协议将台词发送给 媒体服务器， 触发媒体服务器启动搜索；
步骤 3: 媒体服务器根据用户输入的台词在媒体数据库的文本字幕 文件中搜索， 将搜索到的影片信息生成 HTML文件， 其中， 搜索匹配可 以是 4青确匹配或模糊匹配；
步骤 4: 媒体服务器将 HTML文件通过 HTTP协议返回给用户终端设 备；
步骤 5: 用户根据搜索信息选择希望观看的影片， 并且用户可以根 据搜索到的信息选择是否从出现该台词的时段开始播放或从头开始播 放， 即从影片中出现该台词的地方或者重头开始播放用户所选择的影 片；
步骤 6: 用户终端设备根据用户选择， 向媒体服务器发送媒体播放 请求；
步骤 7: 媒体服务器根据用户终端设备请求， 播放对应的影片。 请参阅图 2, 本发明实施例的 IPTV节目定位方法， 其包括以下步骤： 步骤 10: 用户在观看影片的过程中输入影片中的一段台词， 其中， 用户通过语音识别技术输入影片台词或遥控器、 键盘等设备输入影片台 词；
步骤 20: 用户终端设备通过网络协议将接收到的台词发送给媒体服 务器， 触发媒体服务器启动搜索；
步骤 30: 媒体服务器根据用户输入的台词在对应的影片的文本字幕 文件中搜索， 其中， 搜索匹配可以是精确匹配或模糊匹配；
步骤 40: 媒体服务器搜索到和台词对应的片段， 获取该台词对应的 影片片段的时间信息， 然后从该时间点开始播放， 这种方式称为定位播 放；
步骤 50: 媒体服务器没有搜索到和台词对应的片段， 从当前播放位 置继续播放影片。
在上述的实施例的步骤 40中， 媒体服务器搜索到和台词对应的片 段后还有用户判断的过程， 即用户判断是否需要从搜索到的片断开始播 放。
