MPEG PLAY Command

Autodetect
If the stream type is set to 00h, the decoder will parse the beginning of the stream
to determine stream type. The decoder can detect:

• MPEG-1 System stream
• MPEG-2 Program stream
• MPEG-2 Transport stream
• Audio/Video PES
• Video Elementary stream
• Film Mode (24 frames/second; 3:2 pull-down)
• NTSC/PAL
• MPEG Chroma Format 4:2:0 / 4:2:2

Pre-Black
8-bit pre-black interval in video frames. A value of 0h uses default pre-black (first
frame). To display the first frame of video with no pre-black frames, set a value of 1.

Frame Count
32-bit frame count in video frames. Video and audio will play back for this speci-
fied number of frames. A value of 0h plays in non-frame count mode.

Post-Black
16-bit post-black interval in video frames. A value of 0h uses the default of eight
frames. In Single playback mode, this field specifies the minimum number of black
frames until starting the next play. A value of 0h uses the default of eight frames.
In Switched playback mode, this field represents the amount of black which is
