The invention provides a satellite signal processor, which solves the problem that the existing satellite set-top box needs to transmit broadcast satellite TV signals and positioning signals to the satellite set-top box through different data lines, which increases the complexity and cost of installation. The invention includes: The head receives the broadcast satellite TV signal and performs mixing and amplification processing on the broadcast satellite TV signal; the active antenna unit receives the GNSS positioning signal of the global navigation satellite system and amplifies the GNSS positioning signal; the intermediate frequency signal processing unit The broadband noise level in the satellite TV intermediate frequency signal output by the head is attenuated, and the difference between the power of the broadband noise level of the attenuated satellite TV intermediate frequency signal and the power of the GNSS positioning signal output by the active antenna unit is less than the preset threshold ; The first combiner, which combines the amplified GNSS positioning signal and the attenuated satellite TV intermediate frequency signal, and transmits it 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...
