Abstract
The invention provides a high-speed multichannel data splitting transmission processing device which meets the requirement of realtime processing of video data with the band width being greater than 5Gbit/s. The high-speed multichannel data splitting transmission processing device is internally provided with a man-machine communication module and a data splitting module, wherein the man-machine communication module provides a splitting instruction parameter to the data splitting module according to a control instruction received through a man-machine communication interface; the data splitting module comprises two or more registers; the input video data is divided into multichannel synchronous video data by a ping-pong type caching technology and under the action of a synchronous clock; and the video data is assigned to a display screen through a transmission module and a receiving module. According to the high-speed multichannel data splitting transmission processing device, a digital video input with the input band width being 5 Gbit/s or above 5Gbit/s can be split into at least two digital video outputs synchronously, and the requirement of realtime processing of the video data with the band width being greater than 5Gbit/s is met.

Background technology
Present control system can not receive the video data input that bandwidth is higher than 5Gbit/s, is limited to 1080P, 60Hz on the resolution of video, for the video of higher resolution or the video source of higher repetition frequency, can not process, and uses comparatively limited.
Summary of the invention
The invention provides a kind of high-speed data multichannel and split transmission processing device, be higher than the needs of real-time processing of the video data of 5Gbit/s to satisfy bandwidth.
For realizing above goal of the invention, the invention provides following solution:
A kind of high-speed data multichannel splits transmission processing device, its input has man machine communication interface and video data input interface, output has a plurality of video data output interfaces, this high-speed data multichannel splits and is provided with man-machine communication module and at least one Data Division module in the transmission processing device, the man-machine communication module is according to the control command that receives via man machine communication interface, provide and split order parameter to the Data Division module, comprise two or more registers in each Data Division module, adopt the ping-pong type caching technology, the video data with input under the effect of synchronised clock is divided into the Multichannel synchronous video data consistent with register quantity; By sending module and receiver module video data is distributed to display screen.
Above-mentioned video data input interface can be the video interfaces such as DVI, HDMI, SDI, DP, and the video data output interface can be selected the DVI interface, and man machine communication interface is generally RS232, RS485, USB, Internet Transmission etc.
The present invention has the following advantages:
1, can receive bandwidth is 5Gbit/s and above digital video input.
2, be the input bandwidth that 5Gbit/s and above digital video input are split as at least digital video output of two-way synchronously, every road output bandwidth is not higher than 5Gbit/s, and does not change the repetition frequency of input, and field frequency does not change.The multichannel outlet chamber keeps field synchronization.
