The processor that is connected with described USB interface, after the program stream of the different video form that described USB interface is sent carries out demultiplexing, decoding and audio/video coding, the output digital audio-video signal, perhaps pass through D/A switch after, output analog audio-video signal;
With the output interface that described processor is connected, the digital audio-video signal and the analog audio-video signal of described processor output are exported to display device by described output interface; And
With the memory that described processor is connected, store various data required in the software, running software of the operation of described processor and be used for the buffer memory of video decode and the buffer memory of display graphics.
In the said structure, described output interface comprises with described processor and being connected, and the analog audio-video signal of described processor output is sent to the RCA interface of described display device.
In the said structure, described output interface also comprises with described processor and being connected, and the digital audio-video signal of described processor output is sent to the HDMI interface of described display device.
In the said structure, described memory comprises with described processor and being connected, and stores the program storage of the software of described processor operation.
In the said structure, described memory also comprises with described processor and being connected, storing software required various data in service and be used for the buffer memory of video decode and the data in buffer memory of display graphics.
In the said structure, the program stream of described different video form comprise MPEG-2, MPEG-4P2, H.264, the program stream of WMV9, VC1 and AVS form.
Another purpose of the present utility model is to provide a kind of set-top box, and described set-top box comprises the set-top box body, and described set-top box also comprises above-mentioned many video formats decoding device.
In the utility model, many video formats decoding device can be decoded to the program stream of different video form, the set-top box of many video formats decoding device with existing support MPEG-2 form combined, just can spend very little cost upgrading set top box, having solved existing set-top box can not the compatible problem of supporting the various video coded format.
