Problems solved by technology

But this will greatly increase the consumption of network traffic
[0004] On the other hand, no matter what kind of transmission technology is used, the quality of the network has a fatal impact on video playback. Network freeze will cause interruption of live broadcast, which usually makes users miss the program content of this period

Abstract

The invention discloses a method and a client for realizing network video live broadcast, wherein the client determines whether an interruption duration time period in live broadcast playing exceeds a preset threshold; if yes, the client acquires a time shift index file of a video service from a service platform. The acquired time shift index file is used as a local index file for being stored. Content fragment information which corresponds with a live broadcast interruption position is searched from the local index file. A video fragment which corresponds with the content fragment information is acquired from the service platform. The video fragment is played for restoring video playing at a live broadcast interruption position. According to the method and the client, through automatically switching between the live broadcast index file and the time shift index file on the condition of low network quality, user experience in viewing a live broadcast program is improved on the condition of low network quality, and furthermore relatively low network expenditure can be kept.

Description

technical field [0001] The invention relates to the field of network video, in particular to a method and client for realizing network video live broadcast. Background technique [0002] In recent years, due to the simplicity and efficiency of the HLS (Http Live Streaming) protocol, more and more online video services are implemented through the HLS protocol. The HLS protocol defines the behavior of the client and the information and content that the client can obtain from the server through the index file. For example, the live index file contains the latest content fragment information pushed by the encoder, and the client can play the fragment content according to these information, and refresh the live index file after a period of time to obtain new content fragment information . When the number of content fragments contained in the live index file is sufficient, the client can even locate and play at the previous time. From the perspective of business form, it will au...
