In video memory.Decoded vedio data is typically all in the form of the Y-component of yuv space, U components, V component.By
Belong to hard decoder in the decoding process, so performance is very high.Above-mentioned intellectual analysis equipment can be that a single physics sets
It is standby, or be present on other physical equipments as a logic entity.
After the completion of decoding, need the vedio data in video memory to be copied in internal memory, after such CPU could be to decoding
Vedio data carry out intellectual analysis.CPU may only need to the video figure using local when intellectual analysis are carried out
As data.Such as, when carrying out mixing line detection, it is only necessary to use some vedio datas mixed near line;Entering
When row Face datection, may only need to use the corresponding vedio data of face.So from this point of view, only need
Partial video view data in video memory is copied in internal memory.When implementing, user can predefine
The area-of-interest of intellectual analysis, when then vedio data is replicated in video memory is performed, only copies area-of-interest
Vedio data.User presets the mode of area-of-interest and belongs to prior art, will not be described here;Intellectual analysis
