The present invention relates to the field of Internet Protocol Television IPTV. More specifically, the present invention relates to video topics in the video on demand service of IPTV. Background technique

In the Internet Protocol Television/Video On Demand (IPTV/VOD) service of the Internet, the topic is an important form of content. A topic refers to a collection of content of the same or similar content. For example, during the World Cup, IPTV/Cable operators can produce "World Cup" video features, including the highlights of some of the channels that have ended, and publish the topic to the Electronic Program Guide (EPG). Through the EPG, you can see the topic page, browse the video of the game included in the topic, and then select the game video of interest for on-demand.

The topics are divided into graphic topics and video topics. The graphic and thematic topics have been quickly produced through the graphic page customization tool, but the video-based topics remain in the manual operation stage, and the video required for the video-based theme needs to be separately published to the content distribution network (CDN). Time Shift TV/TV on Demand/Network Personal Video Recorder (TSTV/TVOD/NPVR) video service has recorded channel program videos in the CDN, wasting CDN storage space.

After the program is successfully released, the operator will display the video program on the CMS. In conjunction with the target video feature, and synchronizing the program metadata to the EPG, the EPG displays the newly added program in the target video feature.

In the above prior art, there are the following deficiencies, such as: video programs required for video thematic services The video programs that have been recorded in the TSTV/TVOD/NPVR video service in the CDN cannot be shared, and the video programs in the video feature are stored for a long time, resulting in serious waste of CDN storage resources. Secondly, the video production process requires manual participation. The workload is large, the time required is long, and the topic update is slow. It can't meet the requirements of fast on-line and fast update of IPTV/VOD service content. Finally, the video theme production relies on proprietary recording equipment, and operators invest a lot.
