Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0027] A kind of satellite TV system quick star search method, please refer to the appendix figure 1 shown, including the following steps:

[0028] S101. Obtain a TV program search request of the TV device. The TV program search request includes tuner identification information and satellite identification information, and selects the tuner and satellite to be used through the tuner identification information and satellite identification information;

[0029] S102. When the tuner locks the radio frequency signal of the satellite digital broadcasting channel, record the azimuth and elevation angles of the satellite receiving device, and record them in the historical satellite digital broadcasting channel search table;

[0030] S103. Quickly...

Abstract

The invention discloses a rapid satellite searching method for a satellite television system, which comprises the following steps: acquiring a television program searching request of television equipment, the television program searching request comprising tuner identification information and satellite identification information, and selecting a to-be-used tuner and a satellite according to the tuner identification information and the satellite identification information; When the high frequency head locks a frequency emission signal of the satellite digital broadcast channel, recording an azimuth angle and an elevation angle degree of the satellite receiving device, and recording the azimuth angle and the elevation angle degree in a historical satellite digital broadcast channel search table; And quickly acquiring the satellite digital broadcast channel through the historical satellite digital broadcast channel search table. The azimuth angle and elevation angle information of each time of program searching can be recorded, when a certain program needs to be played, the azimuth angle and the elevation angle can be rapidly obtained through a historical satellite digital broadcast channel search table, meanwhile, a plurality of high-frequency heads are arranged, a plurality of satellites can be searched at the same time, and the content of a satellite television is increased.

Description

technical field [0001] The invention relates to the technical field of satellite television, in particular to a method for quickly searching for satellites in a satellite television system. Background technique [0002] Satellite LNB is also called Low Noise Reducer (LNB). Its internal circuit includes a low-noise frequency converter and a down-converter, which completes low-noise amplification and frequency conversion functions, and at the same time serves as an MMDS (multi-channel multipoint distribution service, also called wireless cable) receiving front end. The working principle of the satellite tuner is to reduce the frequency of satellite signals, such as reducing 3.4 to 4.2GHz (C band) or 11.7 to 12.75GHz (Ku band) or 20 to 22GHz (Ka band) to the frequency of ordinary satellite signal receivers. It can demodulate the intermediate frequency signal of 950 ~ 2150MHZ frequency. A satellite signal receiver refers to an electronic device that converts the output signal ...
