Downconvert - The process which reduces the number of pixels in the scanning format used to represent an image, so that it may be reproduced on a display of lower resolution, such as a conventional television. For example, an HDTV image may be downconverted to an SDTV or NTSC image, but in the conversion significant detail information may be lost.
MPEG-2 - (Motion Picture Experts Group technical standard 2) - This is a widely used standard for digital encoding of motion pictures. It typically achieves a 50 to 1 compression of data.
