Description

technical field [0001] The invention relates to the technical field of information processing equipment, in particular to a novel wireless transmission tuner device. Background technique [0002] The high-frequency head is a device used by the TV to receive high-frequency signals and demodulate video information, and it is also the first part of the public channel. At present, the tuners used in TV sets are generally divided into digital signal tuners (referred to as digital tuners) and analog signal tuners (referred to as analog tuners). Simply put, it is a TV signal tuner and a high-frequency signal amplifier, and a satellite TV decoder. With the development of microwave technology, more and more TV signals are transmitted in real time over long distances through satellites. As a common household microwave product, the tuner occupies an unattainable position in the TV reception of countless families because of its relatively high cost performance. The existing LNBs on t...
