Audio and video distributing method and device thereof

Abstract

The embodiment of the invention provides audio and video distributing method and device. The method comprises the steps of: covering a grating layer on the surface of a display device, displaying video signals of programs of a plurality of channels on the display device by lines at intervals; playing audio signals of the programs of the channels in a mixing manner; and playing reverse audio signals corresponding to the programs of different channels in different angles. According to the embodiment of the invention, a plurality of audio and video programs are provided for different audiences through the same audio and video device without special devices under the condition of no damage on the integrity of a picture, thus better user experience is obtained. Meanwhile, requirements on the system and the circuit are low. In addition, when the video distribution is solved, different audiences can receive respectively independent audios without wearing earphones.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a video and audio distribution method and device thereof. Background technique [0002] With the increasing use of digital TV, there is a need to watch multiple TV programs on the same display screen. For example, family members want to share the display screen and audio equipment in the same living room, which not only maintains the warm family atmosphere, but also You can watch your favorite programs individually. [0003] At present, TVs with a picture-in-picture function have appeared on the market, which reduce a complete picture into one large and one small or several equal-sized display areas, and each display area plays a different TV program. In addition, there is also a technical solution for broadcasting different programs at frequency intervals. [0004] The technical solution for broadcasting different programs according to frequency intervals is as follows: f...

Problems solved by technology

[0005] However, in the process of realizing the present invention, the inventor found that the defect of the prior art lies in that: using the picture-in-picture technical solution, it is impossible to expand any complete picture to the whole screen, destroying the integrity of the picture, and the reduced picture cannot let the audience Satisfied; at the same time, multiple images are played at the same time, which subjectively interferes with the audience's attention; and, this solution only solves the distribution of video, but does not solve the distribution of audio

[0006] However, if the technical scheme of broadcasting at frequency intervals is adopted, the display device needs a sufficiently high refresh rate. When playing high-definition programs, the data transmission rate per second is very high, and the requirements for circuits and chips are strict; at the same time, the audience needs to wear special devices. Poor, wearing glasses for a long time will cause visual fatigue; moreover, this solution only solves the distribution of video, but does not solve the distribution of audio
