5.1.43. int SetDisplayRegionPosition (UINT nDisplayChannel,UINT nRegion,
UINT nLeft,UINT nTop)
Parameter:
UINT nDisplayChannel the index for the display channel
UINT nRegion the area that want to adjust
UINT nLeft,UINT nTop the position that want to put
Explanation:
Adjust the position that display
5.1.44. int FillDisplayRegion (UINT nDisplayChannel,UINT nRegion,
unsigned char *pImage)
Parameter:
UINT nDisplayChannel the index for the display channel
UINT nRegion the area that want to fill
unsigned char * pImage the point that YUV420 image
Explanation:
Fill the area by YUV420 image. The size of the Image must equal to the area.

5.1.45. int SetDecoderAudioOutput(UINT nDecodeChannel,UINT bOpen,
UINT nOutputChannel)
Parameter:
UINT nDecodeChannel the index for the decode channel
UINT bOpen 1 – open; 0-- close
UINT nOutputChannel the index for the display channel
Explanation:
Set the decoding audio output. Put the nDecodeChannel decoding audio to
nOutputChannel output. There have 2 audio output channel in the DS-4002MDI.So the
nOutputChannel must be 0 or 1,There have 4 audio output channel in the 4004MDI. So
the nOutputChannel must be 0,1,2 or 3.The Sdk will close the former audio output
before start new data output
5.1.46. int SetDecoderVideoOutput(UINT nDecodeChannel,UINT nPort,UINT bOpen,UINT
nDisplayChannel,UINT nDisplayRegion,UINT nReserved)
Parameter:
UINT nDecodeChannel the index for the decode channel
UINT nPort the output port for the decode
