Abstract

The invention provides a satellite signal processor, which solves the problem that an existing satellite set top box needs to transmit a broadcast satellite television signal and a positioning signal to the satellite set top box through different data lines, thus the installation complexity and installation cost are increased. The satellite signal processor comprises a tuner used for receiving the broadcast satellite television signal, and performing mixing and amplifying processing on the broadcast satellite television signal; an active antenna unit used for receiving a positioning signal of a Global Navigation Satellite System GNSS, and performing amplifying processing on the positioning signal of the GNSS; an intermediate frequency signal processing unit used for performing attenuation processing on a wideband noise level in a satellite television intermediate frequency signal outputted by the tuner, wherein a difference value of the power of the wideband noise level of the attenuated satellite television intermediate frequency signal and the power of the positioning signal of the GNSS outputted by the active antenna unit is smaller than a preset threshold; and a first combiner used for combining the amplified positioning signal of the GNSS and the attenuated satellite television intermediate frequency signal, and transmitting the combined signals to the satellite set top box.

Description

technical field [0001] The invention relates to the technical field of satellite signal processing, in particular to a satellite signal processor. Background technique [0002] The State Administration of Radio, Film and Television takes advantage of the large coverage and low cost of satellite coverage, and hopes that DBS, as a supplement and extension of cable and terrestrial digital TV, can cover areas that it cannot reach. Send TV signals to thousands of households, so that areas where cable TV cannot reach can watch about 58 sets of TV programs for free. [0003] In order to prevent unscrupulous people or organizations from installing live star set-top boxes in areas where cable TV reaches, causing confusion and unnecessary economic losses in the management of cable TV and live star TV. At the same time, for the healthy development of the TV management system, the State Administration of Radio, Film and Television has been developing and updating the anti-cracking live...
