Data transmission method and device

Abstract

The embodiment of the invention provides a data transmission method and device. The method comprises the steps of acquiring the data transmission progress of each data transmission channel; detecting whether the data transmission progress of the target data transmission channel meets a preset channel adjustment condition or not; if so, sending a first channel control signaling to a first data sender and a second data sender to instruct the second data sender to replace the first data sender to transmit video data through the target data transmission channel, wherein the first data sender is a data sender corresponding to the target data transmission channel, and the second data sender is a data sender corresponding to the data transmission channel with the fastest data transmission progress. According to the method, the problem that the data transmission progress of each data transmission channel is inconsistent and the fluency of video playing is influenced in the prior art is solved, and the effects of balancing the data transmission progress of each data transmission channel, improving the video data downloading speed and reducing video playing lagging are achieved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a data transmission method and device. Background technique [0002] In order to increase the speed of video data transmission, the data uploader can upload video data through multiple data transmission channels for the data downloader to download. However, in the multi-channel streaming P2P mode, the video data that needs to be pushed by each data transmission channel is when the connection is established. When it is negotiated by the data downloader and the data uploader, it is easy to cause the problem that the data transmission progress of each data transmission channel is inconsistent. For playback scenarios, the data transmission channel with the slowest data transmission progress will determine the number of seconds of continuous buffering, which affects the smoothness of video playback and reduces the user's video viewing experience.

[0002] In order to increase the video data transmission speed, the data uploader can upload video data through multiple data transmission channels for the data downloader to download, but in the multi-channel streaming P2P mode , the video data that each data transmission channel needs to push is negotiated by the data downloader and the data uploader when the connection is established, and it is easy to cause the problem that the data transmission progress of each data transmission channel is inconsistent

For playback scenarios, the data transmission channel with the slowest data transmission progress will determine the number of seconds of continuous buffering, which affects the smoothness of video playback and reduces the user's video viewing experience

[0003] Aiming at the problem that the inconsistent data transmission progress of each data transmission channel in the prior art affects the fluency of video playback, no effective solution has been proposed yet
