Abstract

The invention discloses a family television multi-screen display system. The family television multi-screen display system comprises a branching unit, at least N tuners, at least N demodulators, a main chip, a wireless fidelity (wifi) module and a display screen, wherein the branching unit is connected with each tuner and used for branching received external radio and television signals to N-path radio-frequency signals; each tuner is correspondingly connected with a demodulator, and the tuners are used for tuning the radio-frequency signals to intermediate frequency signals; each demodulator is used for demodulating the intermediate frequency signals to transmission data streams; the main chip is used for decoding each transmission data stream to audio/video signals, one path of audio/video signals is output to a display screen, and other paths of audio/video signals are compressed to program data packets respectively; the wifi module is used for performing both-way communication with an external mobile terminal, and the program data packets are sent to the mobile terminal. By means of the technical scheme, a family television and a mobile device can simultaneously play different television programs, internet support is not required, and played programs are free from mutual interference.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a multi-screen display system for home televisions. Background technique [0002] Restricted by the development of home wireless communication technology and smart mobile terminals, multi-channel demodulation can only transmit different TV programs to traditional TVs through wired methods in the early stage. With the development of technology, smart mobile terminals and wifi direct technologies are advancing by leaps and bounds. It has become a common thing to use a mobile terminal to connect to a wireless network to watch video programs online in the living room. But at present, after the mobile terminal is connected to the wireless network, it can only visit the video website to watch the video resources uploaded from the network, and cannot watch TV programs in real time. Even the programs broadcast live on the network are delayed, which affects the viewing experience. ...
