Problems solved by technology

[0003] However, in the solution of multi-decoder cascading, there are also technical problems to be solved
Because it is usually difficult for different devices to have a completely unified hardware clock, when multiple decoders are spliced ​​to play the same media stream, they often appear out of sync, which seriously affects the display effect

Abstract

The invention provides a synchronous playing method, device and system, an electronic device and a readable storage medium, and the method comprises the steps: enabling each device to play a code stream through employing the same preset reference sequence, and enabling a slave device and a master device to maintain the synchronization of a playing reference; and the master device encapsulates the playing timestamps corresponding to the code streams to the protocol heads of the code streams and sends the playing timestamps to the slave devices, so that the code streams are forwarded while corresponding synchronization information is sent to the slave devices, the synchronous playing effect is effectively improved, the playing delay is reduced, redundant broadcast messages are reduced, and the upper limit of the cascading scale of a product can be improved.

Description

technical field [0001] The present application relates to the field of multimedia technology, in particular, the present application relates to a synchronous playing method, device, system, electronic equipment and readable storage medium. Background technique [0002] In order to cope with the increasing multimedia data, especially the playback and display of multimedia, a multi-decoder cascading solution has emerged as the times require. It is economical and flexible, and can effectively overcome the limited decoding and display capability of a single decoder. Moreover, due to the flexible networking mode, it can cover various application scenarios such as large, medium and small scales. Under the condition of sufficient bandwidth, it can provide decoding and display services with a large number of channels. [0003] However, in the multi-decoder cascading solution, there are also technical difficulties to be solved. Because it is usually difficult for different devices ...
