Component video signal
A video signal system where parts of information necessary for reproducing image signal comprised of the three primary colors of light are transmitted via separate signal lines. Types of signal, such as R/G/B, Y/PB/PR, etc., are available.
Composite video signal
A video signal comprised of three kinds of signals combined: an image signal made up of luminance and chrominance signals using the frequency multiplication technique, burst signal providing the basis for color reproduction, and synchronization signal.

Interlaced scanning

Playback control (PBC)

Progressive scanning
By progressive scanning, all the horizontal lines of a picture are displayed at one time as a single frame. This system can convert the interlaced video from DVD VIDEO into progressive format for connection to a progressive TV. It dramatically increases the vertical resolution.
Region code
A system for allowing discs to be played back only in the regions designated beforehand. All the countries in the world are divided into six regions and each region is identified by a specified region code (or region number). If the region code of a disc matches that of a player, the player can play back the disc.
Sampling frequency
Frequency of sampling data when analog data is converted to digital data. Sampling frequency numerically represents how many times the original analog signal is sampled per second.
