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 ...

Two broad categories of compression are currently in use. In lossy compression, data is intentionally discarded. As a result, the decompression of the data doesn't exactly match the original data.

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 ...

Power is an increasingly important consideration for the majority of system designers. This is particularly true in the case of small handheld consumer devices such as cameras, camcorders and mobile ...

To wrap up our recent series of articles on VESA video compression codecs, this month we will look at the use of video compression on digital display interfaces, using the DisplayPort 1.4 standard as ...

One student’s desire to get out of a final exam led to the ubiquitous algorithm that shrinks data without sacrificing information. With more than 9 billion gigabytes of information traveling the ...
