Compressed-domain Video Processing
Borko Furht, Oge Marques · 2003
Video compression algorithms are being used to compress digital video for a wide variety of applications, including video delivery over the Internet, advanced television broadcasting, video streaming, video conferencing, as well as video storage and editing. The performance of modern compression algorithms such as MPEG-1, MPEG-2, MPEG-4, H.261, H.263, and H.264/MPEG-4 AVC is quite impressive -- raw video data rates often can be reduced by factors of 15-80 or more without considerable loss in reconstructed video quality. This fact, combined with the growing availability of video encoders and decoders and lowcost computers, storage devices, and networking equipment, makes it evident that between video capture and video playback, video will be handled in compressed video form.
