Because video clips are made up of sequences of individual images, or “frames,” video compression algorithms share many concepts and techniques with still-image compression algorithms. Therefore, we ...

If bandwidth and storage were infinite and free, there would be no need for video compression. However, bandwidth is always limited; the per-byte price of storage decreases over time but it's never ...

Compression is one of the most important criteria in determining quality and cost of ownership in a digital video system. Advances in processing power enable more sophisticated compression techniques.

TANDBERG Television’s EN5990 MPEG-4 encoder delivers three-times greater compression of HD signals than what’s possible with MPEG-2 compression. Recently, DIRECTV announced it would begin using MPEG-4 ...
