Abstract

The invention discloses a satellite tuner circuit which comprises a horizontal signal circuit and a vertical signal circuit. The horizontal signal circuit is connected with a satellite receiver through a first band-pass filter, and / or the vertical signal circuit is connected with the satellite receiver through a second band-pass filter. When the satellite tuner circuit is applied, frequency bands needing to be shielded are filtered out through the band-pass filters, and undesired frequency bands are selectively shielded while needed frequency bands are output so that on one hand, the purpose of shielding programs at a certain frequency band by an operator or a policy maker can be achieved, on the other hand, the bandwidth of the operator can be narrower after selective output, and the cost of the operator can be saved. In addition, the frequency bands needing to be shielded are directly filtered out through the satellite tuner circuit, a user side cannot obtain the frequency bands in the mode of upgrading software or the like, and thus the shielding effect is more reliable. The invention further discloses a satellite tuner comprising the satellite tuner circuit.

Description

technical field [0001] The present invention relates to the technical field of satellite television, more specifically, to a satellite tuner circuit, and to a satellite tuner including the satellite tuner circuit. Background technique [0002] Television is a very commonly used device in people's daily life. As a kind of TV, satellite TV has a wide range of applications. The transmission process of satellite TV is generally a whole set of process in which the microwave signal emitted by the ground base station is transmitted through the satellite for a long distance, and the end user uses a directional antenna to decode the received signal through a decoder and output it to the TV terminal for viewing. [0003] The receiving system of satellite TV generally includes satellite antenna, feed source, tuner, satellite receiver and other parts. The satellite receiver is connected with the high frequency head on the satellite antenna through the coaxial cable, and the high freque...
