Embodiment Construction

[0042] Such as figure 1 and Figure 4 As shown, the satellite TV receiving system of the present invention includes a metamaterial film 10, a feed source KY, a tuner connected to the feed source KY, a wireless transmitter FS connected to the tuner, a signal receiving radio transmitter FS sent A wireless receiver JS and a set-top box JDH connected to the wireless receiver JS.

[0043] In the present invention, the feed source KY is integrated with the high frequency body. For example, it can be the CL11R integrated tuner of Coship Electronics, with an input frequency of 11.7-12.2GHz and an output frequency of 950-1450MHz, which can watch most Ku-band satellite TVs.

[0044] The set-top box, such as the N6188 of Coship Electronics, can be used to receive the satellite TV signal of ChinaSat-9.

[0045] The wireless transmitter FS transmits the data from the tuner to the wireless receiver JS wirelessly, and the wireless receiver JS transmits the received data to the set-top box...

Abstract

The invention discloses a satellite television receiving system which comprises a metamaterial membrane, a feed source, a tuner connected with the feed source, a wireless transmitter connected with the tuner, a wireless receiver used to receive signals from the wireless transmitter, and a set top box connected with the wireless receiver. The metamaterial membrane comprises a first flexible base material and multiple man-made micro-structures attached to the first flexible base material. The satellite television receiving system is convenient and pleasant in appearance, utilizes wireless transmission of data between the feed source and the set top box and does not require complicated cable arrangement. As a conventional paraboloid reflecting board is replaced by the metamaterial membrane, the manufacture is easier and the cost is lower.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a satellite TV receiving system. Background technique [0002] The traditional satellite antenna receiving system is a satellite ground receiving station composed of a parabolic reflector, a feed source, a tuner, and a satellite receiver. The parabolic reflector is responsible for reflecting the satellite signal into the feed and LNB located at the focal point. The feed source is a horn set at the focal point of the parabolic reflector to collect satellite signals, also known as a corrugated horn. There are two main functions: one is to collect the electromagnetic wave signal received by the antenna, transform it into a signal voltage, and supply it to the tuner. The second is to perform polarization conversion on the received electromagnetic waves. The high-frequency head LNB (also known as the frequency reducer) is to reduce the frequency and amplify the sa...
