Abstract

The invention provides a method for transmitting multiplex video signals and displaying video-wall, a system and a processing device, wherein, the method comprises: multiplexing multiplex video signals into simplex digital video signals; transmitting simplex digital video signals through a high bandwidth digital interface; displaying simplex digital video signals which are demultiplexed on the video-wall. The method can acquire signals collected by a multiplex video device, multiplex multiplex video signals into simplex digital video signals, transmit multiplex video signals effectively through the high bandwidth digital interface which utilizes single wire or wireless transmission modes. Comparing with prior art which transmits multiplex analog video signals through a plurality of coaxial cables, the method can reduce cost effectively, solves problems of signal distortion and bad flexibility and expansibility.

Description

technical field [0001] The present invention relates to video technology, in particular to a method, system and processing device for transmission and display of multi-channel video signals. Background technique [0002] With the continuous development of video technology, there has been a technology to shoot multiple videos in real time and provide them to video receivers at the same time. Analog TV Wall) and Digital TV Wall (Digital TV Wall), multi-party video conferencing and monitoring fields have become the main application scenarios of this technology. [0003] In the current video transmission and display technology, for each signal, the obtained standard definition (or low definition) video image is processed accordingly, and then transmitted to the video display processing device for display by using a pair of coaxial cables. As shown in FIG. 1 , when we use multiple video capture devices 120 to acquire information of multiple scenes and display them on multiple di...
