Problems solved by technology

The video transmission method in the cascaded data channel is to encode RGB video data into specially defined Serdes serial data packets, and each serial data packet is regarded as a frame of image video, which is serially transmitted in the channel in real time, that is Each channel can only transmit one set of videos, which limits the number of video windows

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] In order to realize the transmission mode of the micro-packet, the present invention realizes the packing of the micro-packet before the signal arrives at the signal exchange. Two video sources are combined into one channel, transmitted to the switch chip, and then transmitted to other signal processing units through cascaded channels.

[0031] The system structure of the present invention is as figure 1 shown. A video stream control system for a multi-screen processor cascade expansion system, including one or more video input modules, cascade switching expanders and one or more video output modules connected in sequence, and one or more video input modules through The video link transmits the input video stream to the cascaded switch expander, and the cascaded switch expander outputs the video stream to one or more video output modules through the video link...

Abstract

The invention discloses a video streaming control system of a multi-screen processor cascading extended system, which is characterized in that video data streams are respectively packed into n micro transmission units; the micro transmission units are mixed to transmit; and micro packets are only required to be extracted at a receiving end and then are combined to obtain respective video after being decoded. Thus, multiple video groups can be transmitted in a transmission link, that is, a transmission channel can be provided with multiple windows on a large screen. Compared with a traditional cascading transmission mode, the video streaming control system can provide more functions and wider upside potential, and has good transmission data integrity.

Description

technical field [0001] The invention relates to the field of video image processing, in particular to a video flow control system of a multi-screen processor cascade expansion system. technical background [0002] The single-point acquisition system is a simple video image processing system. A single processor completes the acquisition of multiple signals, the processing of video images, and finally the display of a limited number of large screens, such as 4 screens, 8 screens, and 16 screens. The board design is complicated, the backplane requirements are high, the bandwidth requirements are high, the chassis is large and complex, and the application is inflexible. The more screens a single machine processes, the greater the technical difficulty and the greater the requirements. [0003] When the number of screens continues to increase, such as more than 32 screens, and some even reach more than 100 screens, if you simply use a single processor to combine, then the video so...
