Abstract

The invention discloses a device and a method for transmitting video stream between chips of a video conferphone system. Parameters of a video frame are preset. The device comprises a video output port and a front end data processing module which are arranged on the sending chip as well as a video input port arranged on the receiving chip, wherein the front end data processing module is used for continuously storing video data which are positioned between the chips and are to be transmitted in a preset position according to the frame format and configuring parameters sending the video frame and output clock frequency for the video output port; the video output port is used for constructing the video frame according to the configured parameters sending the video frame and sending the constructed video frame together with synchronous signals according to the configured output clock frequency; and the video input port is used for receiving the video frame and the synchronous signals, which are sent by the video output port, and analyzing effective data of the video frame. The invention improves the transmission efficiency of a video bus between the chips and saves the cost and the development cost of a peripheral logic chip required by external synchronization.

Description

technical field [0001] The invention relates to a video conference system, in particular to a device and method for transmitting video streams between chips of the video conference system. Background technique [0002] As the embedded video conferencing system becomes more and more complex, more and more systems adopt the scheme of multi-chip processor cooperative processing, so the video port of the chip is used to transmit the original uncompressed video stream between the processing chips is very common. As the conference TV system has begun to enter the high-definition era, high-resolution video streams not only put forward higher requirements for codec algorithms and chip processing capabilities, but also put forward higher requirements for the throughput of video input and output ports. requirements. Because the video port transmits uncompressed video streams, not only the amount of transmitted data is very large, but also the real-time requirements are very strict. ...
