A video stream output method, device and system

Abstract

The invention provides a video stream outputting method, device and system. The method comprises operation of presetting time threshold value and byte threshold value which comprises the following steps: in step S1, when a play instruction is received, a video stream is read from a server according to the play instruction; in step S2, according to the byte threshold value, the video stream is sent to a signal modulator IPQAM in batches; in step S3, when program clock reference PRC value in the video stream is read, an object time segment for reading the video stream is determined; in step S4, whether reading rectification is needed is determined according to the read PCR value, the object time segment and the time threshold value; if yes, reading rectification is performed, and step S2 is executed when reading rectification ends; if not, step S2 is executed directly. The video stream outputting method, device and system disclosed in the solution can be used for effectively realizing stable output of the video stream.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video stream output method, device and system. Background technique [0002] Television sets have become a necessity and a main leisure and entertainment tool in people's daily life. Every day, people are enriching their leisure life by watching TV programs to understand news, sports events, and entertainment programs. With the broadcasting of digital signals by various TV stations, digital TV interactive streaming media services have gradually been widely used. When the user orders a video or watches a live video, the server sends a playback instruction to the broadcasting program, and the playback program reads the video stream from the server and sends the video stream to IPQAM (signal modulator), and IPQAM decodes the video stream and converts the video stream Send it to the set-top box, and the set-top box controls the TV to play. [0003] In order to stably send ...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, when the video stream is sent, there may be situations in which the video stream with a fixed size includes empty packets, which will cause problems such as frame skipping and blurred screens in the TV during playback. Therefore, the prior art Unable to effectively achieve stable output of video stream
