Method and device for determining live broadcast delay

Abstract

The invention discloses a method and a device for determining live broadcast delay. The method includes: receiving the streaming data sent by the streaming data collection end, extracting the actual collection time of the streaming data from the streaming data, and playing the local playback time according to the time difference between the server and the streaming data player when playing the streaming data. The time is corrected to obtain the actual playback time of the stream data, and then the live broadcast delay of the stream data is determined according to the actual acquisition time and actual playback time. The actual acquisition time inserted into the streaming data in the above method is the time corrected by the server, and then the live broadcast delay is obtained from the actual acquisition time and actual playback time corrected by the server, thus overcoming the difference between the acquisition end and each playback end. Due to the inaccurate time of the client's device, the end-to-end delay cannot be measured, and the accurate calculation of the delay from the acquisition end to the playback end during live video 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
