Embodiment Construction

[0007] Such as figure 1 As shown, the device includes a satellite digital TV set-top box 1, and the satellite digital TV set-top box 1 is connected to a low-noise down-conversion module for receiving satellite digital TV signals. The satellite digital TV set-top box 2 has a built-in wireless transmission module 2, and the wireless transmission module 2 The decoded high-definition digital TV signal is modulated and transmitted to the space. The device also includes a wireless receiving module 3, and the wireless receiving module 3 demodulates the modulated signal transmitted by the wireless transmitting module 2 into a high-definition audio-visual signal and transmits it through the receiving terminal playback device to play it.

[0008] The wireless transmitting module 2 is added in the existing satellite digital set-top box, and the wired cable connection is avoided through the wireless connection between the wireless transmitting module 2 and the wireless receiving module 3,...

Abstract

The invention relates to a wireless satellite television transceiver comprising a satellite digital television set top box and a wireless receiving module, wherein the wireless satellite digital television set top box is directly connected with a low-noise down-conversion module receiving satellite digital television signals; a wireless emitting module is arranged in the wireless satellite digital television set top box; the wireless emitting module modulates and transmits decoded high-definition digital television signals to the space; the wireless receiving module demodulates the modulated signals transmitted by the wireless emitting module into high-definition video signals and plays through play equipment of a receiving terminal. Because a wireless transceiving type is adopted to avoid cable connection, the attenuation of the signals is avoided, and the sensitivity of the signal receiving is greatly enhanced.

Description

technical field [0001] The invention relates to a satellite TV receiving system, in particular to a wireless satellite TV transceiver. Background technique [0002] The current satellite TV receiving system is usually connected with an indoor satellite digital TV set-top box through a cable through a low-noise down-conversion module (LNB) arranged outdoors. Due to the high output frequency of the low-noise down-conversion module (LNB) and the harsh outdoor environment, the signal must have a certain attenuation in the cable, which reduces the sensitivity of signal reception. Contents of the invention [0003] The purpose of the present invention is to provide a wireless satellite TV transceiver with low signal loss and high receiving sensitivity. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: the present invention includes a satellite digital TV set-top box, the satellite digital set-top box is connected with...
