Embodiment 1

[0027] figure 1 A structural diagram of a satellite signal receiving device provided by the first embodiment of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown.

[0028] The satellite signal receiving device includes two tuner modulators respectively, namely a first tuner modulator and a second tuner modulator, wherein each tuner modulator includes a signal source, a tuner, a modulation circuit and a power supply circuit. The signal source, the tuner and the modulating circuit of each tuning modulator are connected in sequence. The power supply circuit is connected to the signal source, and the signal source is powered on or off, and the satellite signal reception of the signal source is turned on by controlling the power supply to the signal source, and the satellite signal reception is turned off by controlling the power off of the signal source. Specifically, the first tuning modula...

[0039] image 3 The implementation flow of a satellite signal receiving method provided by the second embodiment of the present invention is shown, and the details are as follows:

[0040] S301. When the first tuner-demodulator receives satellite signals for playback, and the second tuner-modulator does not need to perform recording or the signal for recording comes from a satellite received by the first tuner-modulator, close satellite signal reception of the second tuner-demodulator.

Abstract

The invention is suitable for the field of satellite communications, and particularly relates to a satellite signal receiving device and method. The method comprises the following steps that when a first tuning demodulator receives satellite signals for playing and a second tuning demodulator does not need to record or recorded signals come from a satellite whose signals are received by the first tuning demodulator, the second tuning demodulator stops receiving the satellite signals, and the satellite signals received by the first tuning demodulator are ringed to the second tuning demodulator. According to the satellite signal receiving device and method, the same or different programs from the same satellite are received by using only one signal source, and the programs are played and recorded.

Description

technical field [0001] The invention belongs to the field of satellite communication, in particular to a satellite signal receiving device and method. Background technique [0002] In daily use, users pay more and more attention to the recording function of satellite receivers. In the existing satellite receivers, if the program to be recorded and the program to be played are not at the same frequency point, it is necessary to use a machine with dual tuner modulators. One of the tuner modulators is used for playback and the other tuner modulator is used for recording. In actual use, most satellite receivers use two independent tuning modulators for modulation. In this case, the two signals are actually completely independent, which is equivalent to two tuning modulators working independently in parallel. If The two tuner modulators receive different satellite signals. At this time, the two tuner modulators work independently in parallel. At the same time, since the two tune...
