Method and device for determining live broadcasting delay

Abstract

The invention discloses a method and a device for determining live broadcasting delay. The method comprises the following steps: receiving streaming data sent by a streaming data acquisition end, extracting actual acquisition time of the streaming data, while broadcasting the streaming data, correcting local broadcasting time according to a value of time difference between a server and the streaming data broadcasting end, obtaining actual broadcasting time of the streaming data, and determining live broadcasting delay according to the actual acquisition time and the actual broadcasting time. In the method, the actual acquisition time inserted into the streaming data is the time corrected with the server, and then the live broadcasting delay is obtained through the actual acquisition time corrected by the server and the actual broadcasting time, thus, a problem of failure in measurement and calculation of end-to-end delay caused by inaccuracy of equipment time of different client sides,such as the acquisition end and each broadcasting end, and accurate measurement and calculation of delay from the acquisition end to the broadcasting end during video live broadcasting is realized.

Description

technical field [0001] The present invention relates to the technical field of network live broadcasting, in particular to a method for determining a live broadcast delay, a device for determining a live broadcast delay, computer equipment, and a computer-readable storage medium. Background technique [0002] Streaming data is data that can be transmitted on the network in a streaming manner, and there will be delays in each link of the streaming data in the process of collection, transmission, and playback. In live video applications or remote camera applications, the higher the real-time requirements for streaming data, the better, and the delay of each link will eventually be reflected as the live broadcast delay from the acquisition end of the live video broadcast to the playback end, so accurate calculation of the acquisition end The live broadcast delay to the playback end is very necessary. [0003] In the prior art, due to the inaccurate time on each client device, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, due to the inaccurate time on each client device, the time of the stream data collection end and each stream data playback end is not uniform, so that the collection time of the stream data obtained directly from the stream data collection end and directly from the The playback time of the streaming data acquired by the streaming data player may not be based on the same time standard, so the live delay calculated based on the difference between the collection time and the playback time may be inaccurate
