Vehicle carried video and audio playing device and method

Abstract

The vehicular video and audio playing device includes CPU and memory unit, at least two control units, at least two data decoding units and at least two receiving units. The memory unit is for storing video and audio data; the CPU is connected to the memory units, the control units and the data decoding units; the control units are for receiving the user's control command; the CPU time division treats the control command and cooperates the operation of other units; the data decoding units are connected to the receiving units to analyze the data from the CPU and drive corresponding receiving unit. The present invention also discloses the vehicular video and audio playing method.

Description

technical field [0001] The invention relates to audio-visual data transmission and processing technology, in particular to a vehicle-mounted audio-visual playing device and method. Background technique [0002] With the development of society and technology, people's quality of life is improving day by day, and their requirements for material life are also relatively improved. For example, the popularity rate of vehicles is increasing year by year. When people choose a vehicle, in addition to demanding comfort and safety in driving, they also require related equipment such as on-board audio and video playback to bring high-quality enjoyment. [0003] At present, the program sources of on-board audio-visual playback equipment generally use CDs, tapes, radios, etc. Such as, a kind of car audio-visual playing device of prior art adopts VCD or DVD etc., and it needs to be matched with the disc selection box, when working, selects the disc that wants to play among the several di...

Problems solved by technology

[0006] But, described prior art still has weak point: because the car audio-visual playing device of prior art needs to be used with the collocation of audio-visual interface equipment in the car, and the development of existing car audio system product stays in the multi-person joint in the car always. The stage of enjoying the same program, that is to say: the audio-visual interface equipment in the car does not provide multiple control devices, and generally can only be controlled by the driver and passengers, and passengers in the car can only passively listen to the same program; and , the prior art car audio and video playback device cannot handle the operation instructions issued by multiple people at the same time, it is impossible for multiple people to play their favorite programs at will according to their personal preferences, and it cannot meet the needs of different passengers

[0007] Secondly, because the car audio-visual player of the prior art adopts the mode that many people enjoy the same program together, it may also interfere with the normal driving of the driver, causing potential safety hazards.
