Problems solved by technology

In traditional P2P live broadcasting, when the playback buffer is empty, the common practice is to wait for the download to fill the buffer and continue playing. However, this method will gradually increase the delay between the content watched by the user and the live source, reducing the Synchronization
Especially in the user environment with poor network conditions, this problem is particularly obvious, which makes the live broadcast users have poor access experience when the network condition is poor, which affects the user experience

Abstract

The objective of the invention is to provide a live video information playing method and device. A first P2P node device is used to determine live slice information to be loaded according to live video information requested by the first P2P node device and by combining with corresponding loading-related information, and load audio slice information and / or video slice information corresponding to the live slice information to be loaded, and then, according to the loaded audio slice information and / or video slice information, the corresponding live video restoring information is acquired to play the live video information. Compared with the prior art, the method and device of the invention can be used to realize the advantage that a user can automatically adjust the loaded video data, such as by abandoning the loading of acertain amount of non-critical video data, in different network states to make the watching of the user on the live video maintains the continuous state and will not be interrupted by data holes, the live video synchronism can be maintained, the information acquisition efficiency of the user can be improved, and the resource utilization rate of the P2P node device can be improved, so that the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of network video, in particular to a technology for playing live video information in a P2P network. Background technique [0002] In some live broadcast events, such as live broadcast of sports games, it is an important measure to measure the quality of live broadcast to keep the content watched by users in sync with the live broadcast source. In a sense, users are willing to sacrifice image quality or Fluency to ensure that the watched live content is as synchronized with the source as possible, so as to avoid missing real-time live scenes. In traditional P2P live broadcasting, when the playback buffer is empty, the common practice is to wait for the download to fill the buffer and continue playing. However, this method will gradually increase the delay between the content watched by the user and the live source, reducing the synchronicity. Especially in the user environment with poor network conditions,...
