The 524 decoded video frame will always be placed in the top left corner of 525 this buffer. For any video which is not 720x576, the buffer will 526 then be cropped to remove the unused right and lower areas, with 527 the remaining image being scaled by the hardware to fit the display 528 area. The video can be scaled both up and down, so a 720x480 video 529 can be displayed full-screen on PAL and a 720x576 video can be 530 displayed without cropping on NTSC. 531 532 Note that the scaling only occurs on the video stream, the osd 533 resolution is locked to the broadcast standard and not scaled. 534 535 Thanks to Ian Armstrong for this explanation. */ 536 h = min(h, 576);
