Abstract

The invention discloses a multi-stream broadcast method and device. The method includes the steps: firstly, selecting one stream from various stream and playing a video; secondly, acquiring continuous smooth display time S and continuous unsmooth display time T of the stream; comparing the continuous smooth display time S and the continuous unsmooth display time T with preset continuous smooth video playing time N, and switching the streams according to comparison results; finally, playing the switched streams. By the aid of the technology, network bandwidth is optimally matched with the streams, a user automatically watches the video as clear as possible on the premise of limited bandwidth, existing video playing fluency is improved, picture quality is ensured, and the method and the device are suitable for practical application.

Description

technical field [0001] The invention relates to the field of audio and video technologies, in particular to a method and device for playing out multi-bit streams. Background technique [0002] At present, many front-end video monitoring equipment or program sources are able to provide multiple streams. The stream refers to the data flow used by video files per unit time. It is the most important part of picture quality control in video coding. If the network bandwidth is small and the network traffic is large, video files with high bit rate will occupy more broadband resources, thereby affecting video transmission and further affecting the smoothness of video playback. If you lower the standard to watch videos, Then the bandwidth is wasted, and it is difficult to guarantee the picture quality. Contents of the invention [0003] Based on the above situation, the present invention proposes a multi-code stream broadcasting method to achieve the best match between the network...
