Description

A video sharing implementation method based on set-top box

technical field

The invention relates to the technical field of information communication, in particular to a highly practical method for realizing video sharing based on a set-top box.

Background technique

At present, radio and television and network content providers basically use digital TV set-top boxes (STB) to provide users with audio-visual services. With the advancement of technology, users have higher and higher requirements for video. Currently, 4K is being promoted, and I believe it will soon With the emergence of products with higher definition such as 8K, the bandwidth required to increase the resolution will inevitably increase exponentially, and new encoding formats will appear. As a result, the existing set-top box decoding cannot provide users with better video services.

A current solution is to replace the set-top box and use a set-top box with stronger decoding capabilities, but the replacement speed of the set-top box cannot keep up with the speed of video encoding. In addition, members of the family have different requirements for video services. A single video service can no longer meet the needs of users. Users think that increasing the number of set-top boxes to meet the needs is not cost-effective. After all, the viewing time in a day is limited.

At present, the replacement speed of existing terminal decoding capabilities is far faster than that of set-top box products. Users have high requirements for video experience and higher definition requirements. On the one hand, transcoding services can reduce network bandwidth, but at the same time greatly The video effect is reduced, these are the bandwidth limitations of the external network, but when the set-top box and the terminal are in the local area network, the network bandwidth limitation is basically negligible, so this method can provide better video sharing services.

Based on the above content, we propose a brand-new solution, the purpose of which is to meet the multi-user video service scenario without relying on the video decoding capability of the set-top box.
