图7是本发明一实施例的媒体内容分发和点播系统的结构框图；包括，内容管理器701，用于向机顶盒702下发推送计划消息，所述推送计划消息中包含预推送的媒体内容ID和预推送时间；以便于机顶盒702根据所述预推送的媒体内容ID和预推送时间生成录制任务，根据所述预推送时间启动所述录制任务，根据所述预推送的媒体内容ID将所述通过组播推送的媒体内容录制保存；机顶盒702，用于接收并保存通过组播推送的媒体内容；获取所述媒体内容对应的内容元数据并进行展示；获取用户基于所述内容元数据的内容点播请求；判断所述点播的媒体内容是否已经通过所述组播推送方式推送成功，若推送成功，则读取所述点播的媒体内容进行播放；否则，根据所述内容元数据请求媒体服务器703播放；媒体服务器703，用于在接收到机顶盒702根据所述内容元数据请求播放所述媒体内容时，向机顶盒702发送所述媒体内容。Fig. 7 is a structural block diagram of the media content distribution and on-demand system of an embodiment of the present invention; Including,
在本发明另一实施例中，机顶盒702还用于在所述媒体内容完成推送时向内容管理器701发送获取所述媒体内容内容元数据请求，所述内容元数据请求包含所述媒体内容的ID；所述内容管理器701根据所述媒体内容的ID，从本地查询并确定与所述媒体内容匹配的内容元数据，并将该内容元数据返回给所述机顶盒702；机顶盒702将所述内容元数据进行展示，以便于用户进行媒体内容点播。In another embodiment of the present invention, the set-
在本发明另一实施方式中，机顶盒702进一步用于将推送结果定期上报给内容管理器701，以便于内容管理器701或者操作员根据推送结果修改推送策略，调整推送方式，提高推送效率。In another embodiment of the present invention, the set-
图8是本发明另一实施例的媒体内容分发和点播系统的结构框图；Fig. 8 is a structural block diagram of a media content distribution and an on-demand system according to another embodiment of the present invention;
包括机顶盒801；内容管理器802；内容编码器803；传输网络804；调度服务器805；媒体服务器806；VOD片库807。Including set-
内容管理器802根据操作员指定的推送计划生成推送任务，下发到内容编码器803，内容编码器803从VOD片库807中提取需要推送的媒体内容并进行编码，之后封装成传输报文，以组播的方式发送到传送网络804。同时，内容管理器802将推送计划通过传输网络804下发到机顶盒801，机顶盒801根据推送计划生成本地录制任务，当一个媒体内容开始推送时，机顶盒801启动录制任务，加入到传输网络的组播组接收组播报文，将接收的媒体内容保存到本地。当用户查看推送的媒体内容时，机顶盒801检查判断哪些媒体内容完成推送(推送成功或推送失败且后续不再推送)。机顶盒801从内容管理器802获取完成推动的媒体内容的内容元数据并向用户进行展示。当用户选择观看某个已经完成推送的媒体内容时，机顶盒801判断该点播的媒体内容是否通过所述组播推送方式推送成功，如果推送成功，则直接从机顶盒本地读取存储的媒体内容进行播放，如果推送不成功，机顶盒801请求媒体服务器806播放该点播的媒体内容，媒体服务器806从VOD片库807读取点播的媒体内容，将该点播的媒体内容发送给机顶盒801。具体流程详见关于图4的描述，在此不再赘述。The
如上所述的媒体内容分发和系统由于在推送媒体内容不成功的情况下，机顶盒可以直接向媒体服务器请求播放该媒体内容。避免了媒体内容因为推送不成功就不能观看的弊端，提高了用户体验。In the above-mentioned media content distribution and system, when pushing the media content fails, the set-top box can directly request the media server to play the media content. It avoids the disadvantage that the media content cannot be watched because the push is unsuccessful, and improves the user experience.
另外，由于媒体内容和内容元数据分开进行发送，这样当内容元数据发生改变和更新后，机顶盒可以实时快速获取，解决了以往因为内容元数据与媒体内容通过组播方式一起发送导致因内容元数据更新和修改，而不能及时发送到终端的弊端，提高了用户体验，也节约了网络资源。In addition, since the media content and content metadata are sent separately, when the content metadata changes and is updated, the set-top box can quickly obtain it in real time, which solves the problem caused by content metadata and media content being sent together through multicast in the past. The disadvantage of data update and modification, but not being sent to the terminal in time, improves user experience and saves network resources.
另外，由于机顶盒定期将推送结果上报给内容管理器，便于内容管理根据上报结果自动调整推送策略，或者用于操作员根据上报结果调整推送策略，例如增加或者减少推送次数，修改推送码率，调整每天推送的时间段等，可以有效提高推送效率，节省网络资源。In addition, since the set-top box regularly reports the push results to the content manager, it is convenient for the content management to automatically adjust the push strategy according to the reported results, or for the operator to adjust the push strategy according to the reported results, such as increasing or reducing the push times, modifying the push rate, adjusting The time period of daily push can effectively improve the push efficiency and save network resources.
