Appendix A 
Glossary 
 
   Christie DS+60/DW30/Matrix 3000 User’s Manual     A-1 
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. 
The time, inside one horizontal scan line, during which video is generated. 
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...

Appendix A: Glossary 
A-2     Christie DS+60/DW30/Matrix 3000 User’s Manual      
A number that uniquely identifies a specific channel retained in projector memory. 
The projector can retain up to 50 channels. 
A menu item that indicates whether an option is currently in effect (checked) or not 
(unchecked). 
The signal representing the color information (hue and saturation) when the image is 
represented as separate chrominance and luminance. Same as “chroma”. 
The range of colors allowed in a specific...

Appendix A: Glossary 
 
   Christie DS+60/DW30/Matrix 3000 User’s Manual    A-3  
A type of rear-projection screen which spreads the light striking it. Screen gain is less 
than 1 but audience viewing angles are increased. 
An adjustment that affects the display of an image. Such display settings include 
contrast, brightness, tint, blanking, size, offsets, and others. 
The maximum frequency of the pixel clock. Also known as pixel clock rate. 
The Enhanced Extended Display Identification Data standard,...

Appendix A: Glossary 
A-4     Christie DS+60/DW30/Matrix 3000 User’s Manual      
A physical connection route for a source signal, described by a 2-digit number 
representing 1) its switcher/projector location and 2) its slot in the switcher/projector. 
Signal sent from a source device to the projector. 
A device, such as the Serial Digital Input Module, that accepts an input signal for 
display by the projector. 
A method used by video tape players and some computers to double the vertical 
resolution...

Appendix A: Glossary 
 
   Christie DS+60/DW30/Matrix 3000 User’s Manual    A-5  
PAL (Phase Alternating Line) video is a 50 Hz standard with 768 x 576 resolution. It 
is found on some video tape and disk players (used primarily in Europe, China and 
some South American and African countries). 
The smallest discernible element of data from a computer-generated image. 
The phase of the pixel sampling clock relative to incoming data. 
The frequency of the pixel sampling clock, indicated by the number of...

Appendix A: Glossary 
A-6     Christie DS+60/DW30/Matrix 3000 User’s Manual      
The output from certain video tape players and video equipment. S-Video separates 
sync and luminance from color information, typically producing a higher quality 
display than composite video. 
The horizontal or vertical frequency at which images are generated. Also known as 
scan rate or refresh rate. 
One horizontal line on the display. 
The horizontal or vertical frequency at which images are generated. 
A video output...

Appendix A: Glossary 
 
   Christie DS+60/DW30/Matrix 3000 User’s Manual    A-7  
The frequency at which images are generated. Vertical frequencies vary amongst 
sources. Also called vertical scan rate. 
The difference between the center of the projected image and the center of the 
projector lens. For clarity, offset is often expressed as the maximum amount of the 
image that can be projected above or below the lens center without degrading the 
image quality. Vertical offset ranges depend on the type...

Appendix B 
IR Remote  
Key Reference 
 
   Christie DS+60/DW30/Matrix 3000  User’s Manual     B-1 
NOTE: The IR remote is a standard component provided with the projector. Use the 
extension cable also provided to convert the IR remote to a wired remote, if desired.  
Refer to Section 3 for a specific description of each key and how to use them correctly. 
 
Toggle keys marked with an “*” require you to press and hold or
 press twice or use with 
the up/down arrow keys. Refer to the description of these...
