Internally the buffers of the PVR350 are always set to 720x576. The
|
|
decoded video frame will always be placed in the top left corner of
|
|
this buffer. For any video which is not 720x576, the buffer will
|
|
then be cropped to remove the unused right and lower areas, with
|
|
the remaining image being scaled by the hardware to fit the display
|
|
area. The video can be scaled both up and down, so a 720x480 video
|
|
can be displayed full-screen on PAL and a 720x576 video can be
|
|
displayed without cropping on NTSC.
|
|
|
|
Note that the scaling only occurs on the video stream, the osd
|
|
resolution is locked to the broadcast standard and not scaled.
