Multi-signal video synchronous playing device and method

Abstract

The invention discloses a multi-signal video synchronous playing device and a multi-signal video synchronous playing method, relates to the technical field of video source playing, and provides the following scheme: S1 time synchronization and S2 video frame synchronization are processes for ensuring that multiple devices operate based on the same time point during playing and keeping complete synchronization of video pictures; by using a time code or other accurate time reference, a common playing starting time point of a plurality of devices can be found so as to coordinate playing of each device, and decoded video signals are displayed on a connected display screen after being adjusted by time synchronization and frame synchronization, so that synchronous playing and picture consistency among the plurality of devices are ensured; the plurality of decoders in the device can realize time synchronization and video frame synchronization so as to ensure that a plurality of devices start to play video contents at the same time point and keep smoothness and consistency of pictures, so that synchronous playing of multi-signal videos can be realized.
