Embodiment Construction

[0031] Fig. 1 shows the schematic diagram of the circuit inside the TV of the present invention, as shown in the figure, the TV of the present invention includes: a signal receiving unit 110, a control unit 120, an audio channel switching unit 130, a sound processing unit 140, and a video channel switching unit 150 And video processing unit 160, intermediate frequency demodulation unit 170. in:

[0032] The signal receiving unit 110 is used for receiving various signals. Wherein, the signal receiving unit 110 includes a TV tuner 111, which is used to receive a TV signal after being decoded and output a video signal (such as a CVBS signal) and an audio signal after being demodulated by an intermediate frequency demodulation unit 170. The TV tuner 111 can use a single high frequency Head, can also use dual high-frequency head. When dual tuners are used, dual video signals and audio signals can be decoded. When the TV supports multi-screen display (such as picture-in-picture, p...

Abstract

The present invention provides a TV audio playing method comprising: receiving a selection order from an audio access interface; and controlling access of the audio access interface to a voice channels inside TV. The present invention also provides a TV for realizing the TV audio playing method, which includes: audio access interfaces on different TV view mode for receiving different audio signals and sending them to an audio channels switching unit; the audio channels switching unit connecting those different audio frequency interfaces and the inside voice channels for access or cut-off there between; an audio channels switching control unit for controlling the selected audio frequency interface to be accessed to the inside voice channels based on the user's selection. With this invention, audio playing under non-currently receiving mode can be realized.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a method for playing television audio and a television for realizing the method. Background technique [0002] In addition to being able to receive TV signals (such as cable TV signals), the TV also provides multiple signal input terminals to receive other signals from various external devices. For example, AV input terminals, VGA input terminals, DVI input terminals, etc. are provided. Correspondingly, in order to be able to watch these external signals, the TV is set to multiple receiving modes, such as TV mode when receiving TV signal status, AV mode when receiving AV signal, VGA mode when receiving VGA signal, and VGA mode when receiving DVI signal. It is DVI mode, including HDTV, S-Video and other modes not listed here. [0003] At present, when the TV is switched to a certain mode, the signal input terminal corresponding to the mode will be connected to the video chann...
