Problems solved by technology

[0004] Traditional video playback system architecture such as figure 2 As shown, the publishing end only completes the work of collecting and uploading video frames, and other transcoding, recording, and distribution tasks are completed by the back-end cluster. This design leads to considerable work pressure on the back-end
From the point of view of the publisher, its network uplink bandwidth is limited, but sufficient computing resources are not effectively utilized
The traditional HLS video live broadcast and playback system puts CPU-intensive tasks such as encoding and slicing on the server side. In this way, with the increase of video publishing ends and / or playback ends, the server becomes the bottleneck of the system, which is limited by the computing resources of the server (CPU / GPU), the entire system is difficult to expand, and cannot efficiently support high-concurrency live video services
[0005] On the other hand, existing video systems treat live broadcast and rebroadcast as two different media contents, resulting in different playback URLs during the live broadcast and playback URLs after the live broadcast. It's a big inconvenience

Abstract

The invention discloses a video live replaying system and video live replaying method which uses the HLS(reference manual) protocol as the bottom video play protocol and provides an innovating video dissemination method,computation-intensive tasks(the video coding, packaging, conversion etc)which are completed by the server traditionally are transferred to the publish side, the application of the sever resource is reduced radically, thus the system performance bottleneck is avoided, the function of the sever is streamlined into file storage and distribution, the file distribution is accelerated through CDN(the content distribution web), the system is highly expansibility. A new system is provided, the problem of the live / replaying uniform access URL is solved through sharing the same HLS video index file.

Description

[0001] Technical field: [0002] The invention relates to network video playback, in particular to a video live broadcast playback system and a video live playback playback method. [0003] Background technique: [0004] Traditional video playback system architecture such as figure 2 As shown, the publishing end only completes the work of collecting and uploading video frames, and other transcoding, recording, and distribution tasks are all completed by the back-end cluster. This design leads to considerable work pressure on the back-end. From the perspective of the publisher, its network uplink bandwidth is limited, but sufficient computing resources are not effectively utilized. The traditional HLS video live broadcast and playback system puts CPU-intensive tasks such as encoding and slicing on the server side. In this way, with the increase of video publishing ends and / or playback ends, the server becomes the bottleneck of the system, which is limited by the computing res...
