Abstract

The invention discloses a wireless video signal transmission and display system and method. The system comprises a first network relay, a second network relay, an uninterruptible power supply connected with the first network relay, a power line communication equipment transmitting terminal connected with the second network relay, a third network relay connected with the power line communication equipment transmitting terminal and the uninterruptible power supply, a video source connected with the uninterruptible power supply, a distributor making the power line communication equipment transmitting terminal connected with the video source, a power line communication equipment receiving terminal connected with the power line, and a video receiving terminal connected with the power line communication equipment receiving terminal, wherein the first network relay and the second network relay are connected with a power line. The system and method are applied to small-range power line communication networks, and automatic video transmission channel establishment and high-definition wireless transmission are achieved.

Description

technical field [0001] The invention provides a system and method for wireless video signal transmission and display. Background technique [0002] Power Line Communication (PLC) technology is a communication method that uses low-voltage power distribution lines to transmit high-speed data, voice, image and other multimedia service signals. At present, there are some relatively mature PLC products on the market, which are used for high-definition video image transmission in a small-scale LAN. PLC adopts OFDM (Orthogonal Frequency Division Multiplexing) as the mainstream modulation method, because it can ensure stable and complete data transmission even in a communication environment with severe electromagnetic interference. The HOMEPLUG transport protocol is used for communication. However, these devices often adopt a pure hardware design, and the only way to turn them on and off is infrared remote control, which requires manual intervention and direct operation, and the o...
