Abstract

Embodiments of the invention disclose a method and a device for controlling synchronization output of a digital matrix, and the electronic equipment, relating to the technical field of multimedia andcapable of controlling synchronization output of output units. The method comprises the steps as follows: calibrating output start moments and output periods of each of the output units when each of the output units starts or a particular output unit restarts after an error occurs to make the output start moments and the output periods of each of the output units be the same; receiving, by each ofthe output units, the data to be processed based on the same output start moments; controlling each of the output units to complete processing of the data to be processed and received during the current output period after the data to be processed is received, so that each of the output units synchronously outputs the processed data during the next output period subsequent to the current output period. The device and electronic equipment are provided with corresponding modules for achieving the method. The invention is applicable to the operations of data synchronized output, synchronized control and synchronized transmission.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a digital matrix synchronous output control method, device and electronic equipment. Background technique [0002] The digital matrix usually includes functions such as video matrix switching, audio matrix switching and control information switching. As a video matrix, the key is to realize the switching output of the input video image, that is, to switch the video image from any input channel to any Output channel display, usually an M×N matrix means that it can support M-channel image input and N-channel image output at the same time. In addition, video matrix switching usually also supports functions such as screen division / screen stacking / splicing roaming. Video comprehensive platform, large The screen controller, etc. are typical digital matrices. [0003] Synchronous output usually includes video matrix switching synchronous output, audio matrix switching synchro...
