video format

Due to the classic analog video technology, a distinction can be made between video formats that occur as analog signals in studio technology, storage technology, transmission technology and display technology and others that are compressed, transmitted and displayed as digital signals.

The former include component video signals with RGB as the typical representative, YUV, the luminance signal with two color difference signals, Y/C video with separate luminance and chrominance components, and composite video with FBAS. There are direct correlations between the various video formats; for example, the YUV signal can be derived from the RGB signal by a mathematical connection, and from this the Y/C signal, which in turn forms the basis for the FBAS signal.

The quality of the video storage depends on the application and thus on the storable video format. For professional applications that store the video signals in YUV, there is Betacam for analog recording. Y/C video for high consumer demands can be stored with S- VHS and Hi8. And for general consumer electronics, there is VHS and Video-8.

In addition, special video formats play an essential role in storing video on compact discs(CDs) or DVDs. For digital video, video compression, streaming and display file formats are crucial. These include MPEG, DivX, Advanced Video Coding( AVC), H.261, H. 263, H. 264/AVC, QuickTime, Audio Video Interleave( AVI) and WindowsMedia Video(WMV), as well as Common Intermediate Format ( CIF), Quarter Common Intermediate Format ( QCIF) and HDTV.
