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.
