Example Embodiment

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

[0030] In order to realize the micro-packet transmission mode, the present invention realizes the packaging of the micro-packet before the signal reaches the signal exchange. In the signal standardized packing module, after the traditional Serdes standard is packed, the micro-packaging function is realized through the logic chip, and the multi-packet The video sources are combined into one channel, transmitted to the switching chip, and then transmitted to other signal processing units through the cascade channel.

[0031] The system structure of the present invention is as figure 1 Shown. A video stream control system of a multi-screen processor cascade expansion system, which includes one or more video input modules, a cascade switching expander, and one or more video output modules connected in sequence. One or more video input modules pass through The video link transmits the input...

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...
