Different layers of video transmission and storage each provide their own set of formats to select from.
For transmission, there is a physical connector and signal protocol ("video connection standard" below). A given physical link can over definite "display standards" that specify a specific refresh rate, display resolution, and color space.
Lots of analog and digital recording formats are in use, and digital video clips may even be stored on a computer file method as files, which have their own formats. In addition to the physical format used by the knowledge storage tool or transmission medium, the stream of ones and zeros that is sent must be in a specific digital video compression format, of which a number are obtainable.
Analog video
Analog video is a video signal transferred by an analog signal. An analog color video signal contains luminance, brightness (Y) and chrominance (C) of an analog television picture. When combined in to channel, it is called composite video as is the case, among others with NTSC, PAL and SECAM.
Analog video may be carried in separate channels, as in channel S-Video (YC) and multi-channel part video formats.
Analog video is used in both consumer and professional television production applications. However, digital video signal formats with higher quality have been adopted, including serial digital interface (SDI), Digital Visual Interface (DVI), High-Definition Multimedia Interface (HDMI) and DisplayPort Interface.
