Problems solved by technology

However, when realizing the above-mentioned double-picture function, the fly in the ointment is that the left and right speakers of the TV can only output the sound of one of the pictures, and the sound sources of the earphone and the speaker are consistent, that is, the earphone and the speaker can only play the same video at the same time. sound of video signal
Like this, the program that another picture broadcasts certainly can only be presented to the audience with the form of picture picture in the silent state to appreciate, fo

Embodiment Construction

[0028] The technical solution disclosed in the present invention can be used in a multi-channel audio playback device, but in this specific embodiment, we will specifically describe the application of the invention in a TV.

[0029] The industry usually refers to the state of the number of different pictures displayed on the screen of the same video device as the LayOut state. In addition to the single-window state shown in Figure 1, existing TVs also have dual-picture and multi-picture states. Among them, the double picture includes three states of PIP, POP1 and PBP; the multi-picture includes two states of POP3 and POP12. Since the above-mentioned TV set with multiple pictures is in use, its screen can usually only display two active pictures at the same time. The video picture includes the situation of having two active pictures in the above-mentioned traditional dual-picture and multi-picture states.

[0030] In the state where the TV is displaying two active pictures at ...

Description

technical field [0001] The invention relates to audio playing technology of television, in particular to an audio playing device with multi-channel input and output and a control method thereof. Background technique [0002] With the development of TV technology and the enrichment of TV programs, the traditional single-screen can no longer meet people's viewing requirements. At present, many high-end TV sets have realized the function of playing two or more different video signals at the same time. For example, when a dual-channel TV set is in a dual-screen state, it can play DVDs on one screen and TV programs on the other screen. And for the flat-panel TV with large screen size and high pixel characteristics, which has great development prospects, it adopts dual-screen to play, and its picture quality is clear and its size is also more suitable for viewing. The dual-picture technology of current TV products satisfies the simultaneous viewing needs of many family members wi...
