Resolution Every video display device or video format has a maximum number of Pixels that can be displayed. This resolution is specified as the number of horizontal pixels by the number of vertical pixels. The resolution of a DVD is 720x480 for NTSC discs and 720x576 for PAL discs. Scaling must be used to convert this resolution to the resolution of a Fixed Pixel display. The horizontal resolution of a CRT (i.e., analog) is somewhat ambiguous, as there are no discrete pixels used in this technology.
RGB RGB is short for Red-Green-Blue. The human eye can visualize all colors from various combinations of red, green, and blue light. All color video displays use red, green, and blue to create color. Any signals input to a color display device that are not in RGB format must be converted to RGB before being sent to the display element itself. Except for computer monitors, most video display contain this circuitry internally. When making an RGB connection to a display device, synchronization (timing) signals are also required. This can be accomplished either via RGB+HV or SoG.
RGB+HV Red-Green-Blue + Horizontal-Vertical is one method of transferring RGB video signals. In this connection method, the horizontal and vertical sync (timing) signals are separated from the video signals themselves. Thus a total of five wires are required.
Scaling Scaling is the process of converting a video signal from one Resolution to another. As with any type of signal processing, care must be taken to ensure that the signal is not degraded by the processing itself.
