Embodiment Construction

[0023] For the convenience of description, the following will be described by taking a TV set that can receive two sets of TV programs at the same time as an example. Fig. 1 is a schematic diagram of a TV set capable of receiving two sets of TV programs at the same time. It consists of two sets of digital tuner (digital tuner 1 and digital tuner 2) including digital demodulation part, demultiplexing, multi-channel audio and video decoding, multi-channel audio and video processing, main control CPU, audio Output switching control circuit, speakers or wired / wireless earphones are composed of a large-screen high-resolution display.

[0024] The transport stream (TS stream) data output by the digital tuner after demodulation is sent to the transport stream processor for demultiplexing, and the signal data selected by demultiplexing are sent to perform audio and video respectively. Decoding, the decoded video data is processed by Deinterlace / Scaler, and then superimposed with othe...

Abstract

The disclosed TV device to receive multiset programs at one time comprises: a plurality of digital high-frequency heads parallel to the following circuit, a multiplex digital video frequency decode circuit, a multiplex digital video signal treatment and output circuit to connect and output video signal to a display screen, and a multiplex audio output switch control circuit to output the sound signal to horn or wire/wireless earphone; wherein, the last two circuits connect both to the multiplex digital video frequency decode circuit. This invention is convenient to family.

Description

technical field [0001] The invention relates to a receiving and processing device for a TV set, more specifically, it is a device that uses one TV set to receive signals of multiple sets of TV programs and simultaneously displays images of multiple sets of TV programs on the same display screen. The loudspeaker and the earphone of the TV set receive and play multiple sets of TV programs simultaneously. Background technique [0002] At present, many analog TVs have the function of picture-in-picture. Users can monitor another program through the screen while watching a certain program. The two screens of picture-in-picture are divided into main screen and secondary screen. Only the main screen has audio output. And there is no accompanying sound output from the picture, so it cannot be used for two or more people to watch different TV programs at the same time. Equally, there is also the same shortcoming in the digital TV set of band picture-outside-picture function. [000...
