High-resolution remote video transmitting and encoding equipment

Abstract

The invention discloses high-resolution remote video transmitting and encoding equipment, which is characterized by comprising a video acquisition instruction decoding circuit, a scaling circuit, a transition minimized differential signaling (TMDS) acquisition and high-definition multimedia interface (HDMI) / digital video interface (DVI) conversion circuit, a microprogrammed control unit (MCU) control circuit and more than one RS485-to-RS232 conversion circuit, wherein the integrated output port of the video acquisition instruction decoding circuit is connected with the integrated input port of the scaling circuit; the integrated output port of the scaling circuit is connected with the integrated input port of the TMDS acquisition and HDMI / DVI conversion circuit with the RS485-to-RS232 conversion circuit; the integrated output port of the TMDS acquisition and HDMI / DVI conversion circuit with the RS485-to-RS232 conversion circuit is connected with an RS485 and HDMI / DVI signal integrated input port of the RS485-to-RS232 conversion circuit through a cable; the control output of the MCU control circuit is connected with control inputs of the video acquisition instruction decoding circuit, the scaling circuit and the TMDS acquisition and HDMI / DVI conversion circuit with the RS485-to-RS232 conversion circuit; and if the number of the RS485-to-RS232 conversion circuits is more than two, each RS485-to-RS232 conversion circuit is connected in series with the cable through the RS485 and HDMI / DVI signal integrated output port and the RS485 and HDMI / DVI signal integrated input port. Compared with the prior art, the high-resolution remote video transmitting and encoding equipment has the advantages of multi-group video transmission, remote transmission and convenience in use and control.

Description

technical field [0001] The invention relates to a video transmission coding technology. Background technique [0002] In the existing video transmission technology, one cable can only transmit one group of videos. When multiple groups of videos need to be transmitted, multiple cables are needed, which brings great inconvenience to users who need to transmit multiple groups of video signals. Moreover, limited by signal attenuation, the signal transmission distance is short, which cannot meet the requirements of long-distance transmission. Contents of the invention [0003] The object of the present invention is to provide a high-definition long-distance video transmission encoding device that transmits multiple groups of videos simultaneously with one cable and has a long transmission distance. [0004] The present invention is realized in this way, including video acquisition instruction decoding circuit (Decode), scaling ratio circuit (Scaling), TMDS acquisition and HDMI...
