Christie Digital Systems CX60, CX50, CX67 user manual Glossary

		Appendix A
		Glossary
		This appendix defines the specific terms used in this manual as they apply to this
		projector. Also included are other general terms commonly used in the projection
		industry.
	Active Line Time	' The time, inside one horizontal scan line, during which video is generated.
Ambient Light Rejection		' The ability of a screen to reflect ambient light in a direction away from the "line of
		best viewing". Curved screens usually have good ambient light rejection. Flat screens
		usually have less ambient light rejection.
	Analog Video	' The video output of most computers and videotape machines. Analog video can
		generate a large number of colors.
	Aspect Ratio	' The ratio of the width of an image to its height, such as the 4:3 aspect ratio common
		in video output.
	Auto Source	' The ability of the projector to automatically recognize and synchronize to the
		horizontal and vertical scan frequencies of an input signal for proper display.
	Bandwidth	' The frequency range of the projector's video amplifier.
	Baud Rate	' The speed at which serial communications travel from their origin. In this projector,
		the RS-232 or RS-422 default baud rate of 19200 can be changed to match a
		controlling device. The switcher baud rate of 9600 cannot be changed.
	Blanking Time	' The time inside one scan line during which video is not generated. The blanking time
		of the input signal must be equal to or greater than the retrace time of the projector.
	Brightness	' In projection, brightness usually describes the amount of light emitted from a surface
		such as a screen. It is measured in foot-lamberts or candelas per square meter.
	Candela or Candle	' Unit of measure for measuring intensity of light.
	Channel	' A collection of measurements stored by the projector for a given input source,
		including frequencies, pulse width, polarity, syncs, channel number and location,
		user-adjustable display settings, etc. Use channels to switch between a variety of
		setups quickly, automatically recalling previously defined display parameters.
	Channel List	' A list/menu of previously-defined channels available in projector memory.
	Channel Number	' A number that uniquely identifies a specific channel retained in projector memory.
		The projector can retain up to 99 channels.
