Live broadcast delay method and device

Abstract

The invention discloses a live broadcast delay method and device. The method comprises the following steps: step 1, receiving a video signal and an audio signal of a site; caching the video signal and the audio signal according to a preset time length; 2, after a live broadcast delay instruction is received, delay time required by the live broadcast delay instruction is acquired; 3, releasing the cached video signal and audio signal according to the playing starting time to obtain a delayed live streaming media; and step 4, sending the delayed live broadcast streaming media to a cloud server, and distributing the live broadcast streaming to the client by the cloud server to realize delayed live broadcast. Wherein a gasket switching trigger module is arranged in the cloud server, and after the gasket switching trigger module receives the trigger signal, gasket switching is started, and gasket materials are sent to the client side. Through the method of separately triggering the delay mechanism and the gasket switching, the requirement on the performance of hardware equipment is greatly reduced, extra expensive equipment is not needed, and the cost of live broadcast delay and emergency switching is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the live broadcast field, and in particular to a live broadcast delay method and device. Background technique [0002] With the rapid development of webcasting, more and more traditional radio and television programs have started various forms of webcasting. In order to ensure the public opinion orientation and broadcast safety of radio and television propaganda, and further strengthen the management of radio and television live broadcast programs, according to the relevant Requirements, all live programs must be delayed broadcast. There are currently several ways to delay broadcasting: [0003] (1) Solid-state delayer in pure hardware mode [0004] Pure hardware method (solid-state delayer): the live program starts recording a certain time in advance before the scheduled broadcasting time and stores it in the delayer (establishing a delay), and broadcasts the delayed program at the scheduled broadca...

Problems solved by technology

[0012] For this reason, the embodiment of the present invention provides a live broadcast delay method and device to solve the poor delay quality of the solid-state delayer in the prior art, which is prone to picture jitter, synchronization loss, and color synchronization loss. At the same time, the price Generally expensive, the length of the delay time and the video server need to perform encoding and decoding work at the same time, the requirements for hardware equipment specifications are very high, the storage efficiency of video files is low, and the system performance occupies a large problem
