Controls
A ''virtual control panel'' (VCP) code is a binary code that represents a single command entity in the MCCS language. Each command contains variable number of data parameters and command attributes. The following groups of controls are defined in the standard: * Factory Preset - commands for restoring factory defaults, as well as specifically restoring color, geometry, brightness/contrast, and TV settings defaults, and storing/restoring presets. * Color Adjustment - commands that control color temperature, hue, and saturation. * Geometry Adjustment - commands for adjusting CRT display geometry, such as parallelogram, pincushion, etc. * Image Adjustment - various general commands such as display orientation, degauss, gamma, zoom, focus, brightness/contrast, backlight control, etc. Three categories of controls exist: * Continuous (C) - allow values between zero and a maximum value. * Non-continuous (NC) - only support a limited set of values. * Table (T) - large blocks of data. Control data may be read and write (RW), read-only (RO), or write-only (WO). The display exposes its supported internal controls via capability strings.Versions
