Abstract

The invention discloses a system and a method for wireless transmission of audio and video signals. The system comprises a processor, a wireless network card, wireless data receiving terminal equipment and a display terminal, wherein the processor is used for acquiring audio and video signals, encoding, encrypting and compressing the acquired signals and transmitting to the wireless network card, and the wireless network card is connected with the processor and transmits the signals processed by the processor to the wireless data receiving terminal equipment in a WiFi mode; the wireless data receiving terminal equipment decodes, decrypts and decompresses the audio and video signals sent by the wireless network card so as to re-transcode the audio and video signals into the audio and video signals which can be used by the display terminal and transmits to the display terminal, and the display terminal is in wire connection with the wireless data receiving terminal equipment and displays the audio and video signals re-transcoded by the wireless data receiving terminal equipment. With the invention, the audio and video signals can be safely and reliably output and shown by TVs and other display terminals, so that the transmitting and showing mode of audio and video are more flexible and more diverse.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a system and method for wireless transmission of audio and video signals. Background technique [0002] With the rapid development of multimedia technology, network users' demand for multimedia is increasing day by day, and there is also more demand for the display forms of sound and images. [0003] In the prior art, audio and video multi-channel split-screen technology usually can only achieve two-way split-screen, but two-way split-screen is obviously not enough for most families with multiple display terminals and TVs. Some multi-screen technologies are also more widely used in the combined display of large screens. Many users are eager to break through the small frame of PC monitors, but the price of large-size monitors is prohibitive. Therefore, it is urgently desired that the video signal can be output and presented through a television set. [0004] In addition, in ...
