cPEG™

Welcome to our cPEG™ page. This area is dedicated to those who use their PC to work with MPEG1, MPEG2, and MPEG4 files. MPEG is an acronym for Moving Pictire Expert Group. This subgroup of the ISO body is responsible for defining the digital audio and video compression and encoding standards known as MPEG-1, MPEG-2, and MPEG-4. Since these compression techniques are lossy (information is lost during encoding of the master, so when decoded, the resultant AV streams are not faithful - identical - to the original AV master streams), resulting in diminished quality. That being said, of course they are still excellent or else they would be of no use to the DVD movie industry for example. The use compression arises from the need to reduce the size of files. Technically, an encoding technique could be devised to produce digital encodings so near to the original master the human eye could never differentiate the two. The problem is, resultant files would take up too much space to store and consume an unacceptable amount of bandwidth to transmit. Its a matter of how much the original AV stream is compressed and how much the human eye can tolerate. Each technique compresses more or less than another and are thus more suitable than other for various applications.

Briefly, MPEG-2 is superior to MPEG-1 for compression and quality. Hence its use for TV and computer monitor applications and DVDs. MPEG-4 has the highest compression therefore lowest quality. Hence its use for small display screens and surveillance. MPEG files can be stored on any medium for editing, archiving, and playback purposes. Smaller files (eg. short video clips) may be stored on hard drive (even downloaded from the Internet) or on CD ROM media (cap. 680MB). Larger files (eg. a full feature movie) is typically stored on DVD ROM media (cap. SLSS 4.7GB; DLSS 8.5GB; DLDS 17GB).

Our family of hardware and software tools used to create, manipulate, store, and playback video MPEG files fall under the cPEG™ brand name.
