Abstract

The disclosed emission device for wireless HDTV comprises: a signal receiving unit, an AD unit for video / audio, a compressing and coding unit, a transmission control unit, and a wireless signal transmission unit adopted ultra broadband technique. It also discloses a receiving device. This invention applies 110Mbps speed as ultra broadband technique to realize high-resolution signal and Hi-Fi audio.

Description

technical field [0001] The invention relates to a television signal receiving and transmitting device, in particular to a wireless high-definition television signal transmitting and receiving device. Background technique [0002] Currently, there are two main types of TV signal transmission systems: wired transmission and wireless transmission. Although the wired transmission technology has great advantages in the quality of the transmitted signal, the placement of the TV set is limited by the transmission line. Therefore, it has become a development direction to be able to receive high-quality television signals in a wireless manner. [0003] There are many varieties of existing wireless transmission technologies, and the theoretical bandwidth of the 802.11 series protocol with the largest bandwidth can only reach 54M, which cannot meet the requirements of high-definition digital signals when applied to TV, and the encryption mechanism is not very perfect. Contents of th...
