| 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. |
