Description
Technical field
The present invention relates to multimedia technology field, particularly relate to a kind of playing audio/video and audio-video frequency playing system.
Background technology
For television set, lightening is the designer trends of main flow.To this end, TV is also gradually evolved into: by interior
Put speaker to be separately separated and come as audio amplifier, and traditional TV is as the display device being connected with this audio amplifier.Thus, it is born
A kind of novel separate television.
In existing separate television, it is limited by frivolous ultimate attainment pursuit, and the substantial amounts of electrical equipment itself existed, leads
Cause alternative small-sized high-performance processor few；And consider life-span and the quality of display floater, also tend to choosing
Selecting process frequency relatively low, the processor that caloric value is less, therefore, the disposal ability causing the audio frequency and video of television set is more weak.
Under the spring tide of current whole people's intelligent television, the drawback of this kind of separate television is especially apparent: although this split electricity
Depending on being equipped with installing the intelligent operating system of multiple application (game application, Video Applications, music application), but in the face of negative
When load requires high application, the most unable to do what one wishes, cause user cannot enjoy the joyful user's body that this application brings at all
Test.So cause user to generally require and extra add TV box or special game host for this.
During realizing the application, inventor finds, although can attempt the processor in TV independent of TV
Main body outside, be such as arranged in audio amplifier, so can expand the selection of processor, but this kind of scheme the most at least exists
Following problem: be applicable to the high-performance processor of the use scene of television set in view of the most not a large amount of exploitations, can
Selective quantity is the most less, in order to reach high audio frequency and video disposal ability, may need nonetheless remain for carrying out the customization of processor,
This needs to pay great amount of cost and time beyond doubt；Even if selecting commercially available high-performance processor, relative to traditional TV
For processor, the small frequency of single processor promotes, and also brings along dramatically increasing of cost.
Summary of the invention
