Interlaced scan

In the conventional video system, a picture is shown on the screen in two halves. The interlaced scanning system places lines of the second half of the picture in-between lines of the first half of the picture.

Progressive scan

Progressive scanning displays all the horizontal lines of a picture at one time, as a single frame.

Composite video

A single video signal commonly used in most consumer video products that contains all luminance, color, and synchronization information.

S-video

A video signal which improves picture quality over the standard composite video signal.

Component video

Video signals with three channels of separate information that makes up the picture. There are some types of component video, such as Y/CB(Pb)/CR(Pr) and R/G/B.

Bitstream

The digital signal form of multichannel audio data (e.g., 5.1 channel) before it is decoded into its various channels.

Linear PCM

PCM stands for Pulse Code Modulation. Linear PCM is the usual digital method without compression, used for audio playback of audio CDs, DVD Videos, etc.

Dolby Digital

Dolby Digital provides multichannel surround sound in cinemas from 35 mm film and in the home from laser discs, DVD Videos, and digital broadcast television, cable, and satellite systems. It enables the transmission and storage of up to five full-range audio channels, plus a low-frequency effects channel(LFE), thus 5.1 channels, in less space than is required for just one linear PCM-coded channel on a compact disc.

DTS (Digital Theater Systems)

as Dolby Digital, discs bearing the " " provides fat sound and better signal-to-noise ratio,thanks to the lower audio compression ratio format. It also provides wide dynamic range and better separation, resulting in magnificent sound.
