[0005] However, the HDMI playback or transmission devices in the prior art are all single-function devices, such as DVD players, set-top boxes, TV sticks, multi-screen interactive devices, etc., all need a relatively independent power supply, and an HDMI interface and display device Physical connection, and display devices in the prior art, such as TVs, monitors, etc., generally only provide one or two HDMI interfaces, and generally require manual selection of interface settings when connecting
Moreover, most of the existing multi-screen interactive devices use an external local area network to establish a connection with the smart device, so that the device needs to have a wireless local area network, and corresponding artificial settings are required
These not only cause inconvenient operation for users and reduce user experience, but also increase security risks and use costs by setting too many connecting lines and devices

The invention discloses a high-definition multi-media controller and a main board assembly thereof. The main board assembly comprises a main circuit board, a multi-screen interaction and USB high-definition playing main board, a WIFI main board, an HDMI switching circuit and a master control circuit. The HDMI signal output end of the multi-screen interaction and USB high-definition playing main board and the HDMI signal output end of an HDMI input interface are connected with the HDMI switching circuit respectively, the operating state signal output end of the multi-screen interaction and USB high-definition playing main board and the operating state signal output end of the HDMI input interface are connected with the master control circuit respectively, one output end of the master control circuit is connected with the control input end of the HDMI switching circuit, and the HDMI switching circuit selects an HDMI signal which is in operating connection recently from two HDMI signals according to a control signal of the master control circuit to output the signal to an HDMI output interface. According to the technical scheme, the high-definition multi-media controller and the main board assembly of the high-definition multi-media controller improve user experience and reduce connecting lines.
Description
technical field [0001] The invention relates to the technical field of multi-screen interaction and HDMI high-definition playback, in particular to a high-definition multimedia controller and a motherboard component thereof. Background technique [0002] High Definition Multimedia Interface HDMI (High Definition Multimedia Interface) is an uncompressed all-digital consumer electronics interface standard. It integrates high-definition video and multi-channel audio signals into a single digital interface for synthesis processing. It is a digital technology standard for the home appliance manufacturing industry. It is widely used in DVD players, cable TV / satellite TV set-top boxes (video converters), HDTV and other digital audio-visual equipment. It can effectively improve digital image quality, no analog-to-digital conversion is required. [0003] HDMI interface is currently the most advanced digital TV interface standard in the world, and it is a perfect solution for digital...
