Non-compressed transmitting and receiving integrated display device for wireless digital high resolution audio and video signal

Abstract

The invention discloses an uncompressed wireless digital high-definition audio and video signal transceiver display device which comprises a wireless high-definition transmitting device containing an interface module, an audio and video processing module and a wireless high-definition interface transmitting module and a wireless high-definition receiving display device containing a wireless interface receiving module, a digital audio and video processing module, a video image terminal display module, an audio output module and a bilateral control module of a remote controller, the transceiver display device can be compatible with a plurality of audio and video interfaces, flow media interfaces, network interfaces and TV interfaces for displaying high-definition programs through the uncompressed and ultra-low delayed transmission of signals between the wireless high-definition interface transmitting module and the wireless high-definition interface receiving module. Therefore, the transceiver display device has characteristics of high cover range, high through-wall anti-interference ability, simple system architecture and lower system cost and fully meets a family digital wireless multimedia application.

Description

technical field [0001] The invention relates to a high-definition audio and video receiving and displaying device, in particular to an uncompressed wireless digital high-definition audio and video signal transmitting and receiving integrated display device. Background technique [0002] With the rapid development of digital high-definition audio and video technology, more and more display terminals have the function of receiving and displaying digital high-definition audio and video signals. Among these existing digital high-definition audio and video display terminals, usually through The high-definition audio and video interface connects high-definition audio and video signals in a wired manner. However, in today's digital high-definition audio and video transmission system, there are different wired high-definition video transmission methods such as HDMI, DVI, VGA, YPbPr, etc., because these transmission methods are poorly compatible with each other, it makes it possible ...

Problems solved by technology

This kind of high-definition audio and video receiving and transmitting device capable of wireless high-definition transmission, on the one hand, due to the existence of two boxes in the structure, especially the receiving box is placed outside the display terminal, which causes inconvenience for users in connection and use. Moreover, a separate remote controller is required to control the transmitting and receiving devices; on the other hand, since the wireless transmission is transmitted in a compressed manner, it has brought some disadvantages. As we all know, the compression and decompression of the video itself will bring The decline in image quality, and the compression technology will bring about the increase of technical cost. Not only that, video compression will also be subject to certain restrictions when facing applications (such as the output of high-definition programs that are not allowed to be compressed in Hollywood in the United States), and because The process of compression and decompression will inevitably cause delay, and the video output by some video sources cannot be compressed (such as game consoles, PCs). In addition, many wireless technologies generally have coverage, transmission bandwidth, delay, and image threshold. Effect, insufficient anti-interference ability and many other problems, such as IEEE802.11x series 802.11a / b / g bandwidth up to 54M is unable to transmit high-definition data, the new 802.11n can only transmit compressed high-definition data, and there are relatively Long delay; another example is UWB (ultra-wideband) technology. Although it can transmit high-definition programs, it needs to be compressed and decompressed by codec, resulting in image delay. More importantly, its transmission distance is about 10 meters to resist interference and pass through walls. The capabilities are very poor and cannot fully meet the applications of modern families; in addition, wirelessHD technology also has the disadvantage of short transmission distance
