535
536 Internally the buffers of the PVR350 are always set to 720x576. The
537 decoded video frame will always be placed in the top left corner of
538 this buffer. For any video which is not 720x576, the buffer will
539 then be cropped to remove the unused right and lower areas, with
540 the remaining image being scaled by the hardware to fit the display
541 area. The video can be scaled both up and down, so a 720x480 video
542 can be displayed full-screen on PAL and a 720x576 video can be
543 displayed without cropping on NTSC.
544
545 Note that the scaling only occurs on the video stream, the osd
546 resolution is locked to the broadcast standard and not scaled.
