Abstract

The embodiment of the invention discloses an audio and video transmission method and a digital television terminal. The method comprises the following steps that a converted YPRBP signal in a to-be-transmitted audio and video signal is converted into an RGB (Red, Green and Blue) signal; the RGB signal and an I2S (Inter-IC Sound) signal in the audio and video signal are encoded; and a TS (Transport Stream) signal is generated, decoded, compressed and then transmitted to wireless equipment. Multi-terminal audio and video output can be achieved without buying an additional digital television terminal or performing wiring decoration.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an audio and video transmission method and a digital television terminal. Background technique [0002] With the continuous update of digital TV technology, the functions of digital TV terminals are constantly increasing, which can realize two-way on-demand interaction and provide Internet access services. Digital TV terminals are gradually becoming an inaccessible part of people's lives. [0003] Nevertheless, the main function of digital TV terminals is still to realize the broadcasting of digital TV programs. Taking set-top boxes as an example, families often have more than one TV set at present. For digital TV programs, you need to pay extra to purchase additional set-top boxes from the operator, and if there is no place for digital TV signal cables in the dining room, bedroom, and study room, you need to re-wire and decorate, adding additional The cost has brought great...
