Terminology - 97 Terminology This section provides simple explanations for the terminology used within the manual, items for which explanations are not available, and other complex processes. A/V Mute Temporarily erases the image and sound at the same time. The sound and image can be muted by pressing the [A/V Mute] button on the projector. Press the [A/V Mute] button once again or adjust the volume or display the menu to cancel the mute mode. DVI-D port The input port that conforms to the DVI digital video ratings (Digital Visual Inter- face: Ratings to govern how video signals are digitally transmitted). Synchroniza- tion and tracking misalignments will not occur during transmission. D output port The output port for digital tuners that support the new digital broadcasts within Japan. Remote port Enables the optional remote control receiver to be connected so that multiple items of equipment can be operated with a remote control unit. SRS The three-dimensional acoustic system. This enables wide and deep sound to be listened to. These are adjusted with the [Space] (wide) and [Center] (deep) but- tons. SVGA IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pixels and 600 vertical pixels. SXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal pixels and 1,024 vertical pixels. VGA IBM PC/AT compatible (DOS/V equipment) signals with 640 horizontal pixels and 480 vertical pixels. XGA IBM PC/AT compatible (DOS/V equipment) signals with 1,024 horizontal pixels and 768 vertical pixels. USB An abbreviation for Universal Serial Bus. This is an interface for connecting com- paritively low frequency equipment to the computer. UXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,600 horizontal pixels and 1,200 vertical pixels. Color temperature The temperature of the subject that emits light. A blue hue is attained when the color temperature is high, and a red hue is attained when the color temperature is low. Color differential signal Video equipment transmits signals through three cables as Red-Bright (R-Y), Bright (Y) and Blue-Bright (B-Y). This enables the composite signals (the red, green and blue signals and their brightness signals are transmitted along one cable) to be projected more clearly. Operating system The software necessary to operate the computer. Cool-down A lamp cooling procedure continues to operate even after the power supply has been switched off and the lamp extinguished. The cooling fan will begin to operate when the lamp is entinguished, and button operations will not longer be possible. This period is known as the cooling down period. The amount of time required for the cooling down procedure will differ in accordance with the surrounding tem- perature.
98 - Terminology Contrast By strengthening or weakening the tone of the colors, it is possible to project char- acters and pictures more clearly and attain a softer tint. This is known as contrast adjustment. Stack projection Refers to the simultaneous duplicate projection of images with the use of multiple projectors in order to increase projection image brightness. Theft-protection lock A theft-proof cable (available on the open market) is passed through the holes on the projector case to secure it to a desk or column. These holes support the Micro- Saver Security System manufactuered by Kensington Inc. Synchronization (Sync) Outputs computer signals at a pre-determined frequency. The image will not be projected clearly unless this frequency is aligned with the frequency of the projec- tor. Aligning the signal phasing is known as synchronization. Projected images will be subject to distrubance, blurring and horizontal noise if not synchronized. Tracking Outputs computer signals at a pre-determined frequency. The image will not be projected clearly unless this frequency is aligned with the frequency of the projec- tor. Aligning the signal frequency is known as tracking. Projected images will be subject to distrubance, blurring and horizontal noise if not synchronized.
