Abstract

The invention relates to a ground and satellite combined television receiving system. The system mainly comprises two parts, namely a fused antenna and a fused receiver, wherein the fused antenna is a mixed antenna integrating a satellite antenna with a wireless broadcasting antenna physically; the fused receiver is provided with two demodulators and two interfaces which receive satellite television signals by using a coaxial cable; the fused antenna transmits the satellite television signals and wireless broadcasting signals through one coaxial cable; and the fused receiver is used for supplying power to a satellite tuner, a wireless antenna amplifier, and the remote control steering and steering automatic positioning of the antenna simultaneously. The ground and satellite combined television receiving system is easy to operate and use, has a friendly man-machine interface, and can effectively receive cable digital television broadcasting programs, and satellite and ground digital television broadcasting programs.

Description

technical field [0001] The invention relates to a receiving device in the field of digital television, in particular to a television receiving system combining ground and satellite. Background technique [0002] TV has become an important channel for most people to entertain and obtain information. In cities, they mainly watch TV programs through cable TV. In places where cable TV cannot cover, such as remote areas, rural areas, urban-rural fringe areas, migrant workers People who are outdoors, camping, traveling, traveling by car, and working in the field can receive TV programs through satellite TV, cable digital TV broadcasting, terrestrial wireless digital broadcasting and handheld device digital broadcasting. Generally speaking, cable digital TV broadcasts are mainly concentrated in areas with relatively concentrated populations such as towns, while satellite and terrestrial digital TV broadcasts are mainly distributed in areas with relatively scattered populations such...
