Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing and preferred embodiment:

[0027] refer to figure 1 , figure 2 and Figure 4 Shown in, a kind of fast search satellite tuner 1 of the present invention comprises a support platform housing 11, is provided with satellite tuner body 12, signal demodulation circuit 13 and signal indication in support platform housing 11 device 14.

[0028] The satellite tuner body 12 still works with the same function as the traditional satellite tuner. In the specific implementation process, the signal demodulation circuit 13 can also be integrated in it to reduce product specifications and cost.

[0029] The signal demodulation circuit 13 is mainly used to receive the satellite signal strength indication signal returned by the satellite signal receiver, and then demodulate the indication signal associated with the satellite signal strength indication signal received by the satellite tuner ...

Abstract

The invention provides a speedily searching satellite tuner and a satellite television system, relates to the technical field of satellite television signal receiving devices, and particularly relates to the improvement of a structure of a satellite tuner. The technical problem that the dish antenna is inconveniently installed and adjusted in the traditional manner is solved. The speedily searching satellite tuner comprises a support platform shell, wherein a satellite tuner main body, a signal demodulator circuit and a signal indication device are arranged in the support platform shell. The required cost is low, the stability for installing the traditional dish antenna is high, the special external device is unnecessary, and the operation is simple. A signal of the satellite signal strength is fed back to the signal demodulator circuit by a satellite signal receiver; the signal demodulator circuit sends an indication signal according to the signal of the satellite signal strength, so as to drive the signal indication device; and the signal indication device sends a corresponding antenna status signal for reminding the installation personnel if the dish antenna is at optimum mounting position and angle at real time.

Description

technical field [0001] The invention relates to the technical field of satellite TV signal receiving devices, in particular to the structural improvement of a satellite tuner. 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 of a satellite...
