• Switchable composite and S-Video inputs. The AC217A also supports component video input and RS-232 remote control. OVERVIEW Our Video Scalers convert video to non-interlaced, high-resolution native resolution of any DTV, or plasma projector. What is interlacing? A TV video signal is interlaced, meaning information is actually made up odd field and the even field. First, on the screen. Then, before the odd are painted in between the odd lines. This than the human eye can perceive. In contrast, the computer signal is non-interlaced—horizontal lines are painted progressively, left to right, top to bottom, in a single pass. So the flickering problem interlaced TV does not exist in computer video. Line doublers and quadruplers were developed to convert interlaced TV signals to non-interlaced computer signals. However, when compared to line doublers or quadruplers, both video scalers offer several clear advantages: • When using a video scaler, a projector or display device is not forced to crop, distort, or further process the image in order to display it. • The video scalers can provide outputs at multiple refresh rates. For example, a video scaler can display converted PAL video on projectors that don’t support 50-Hz refresh rates. Or converted video can be displayed at 75 Hz, eliminating flicker. • The video scalers they can display letterbox-aspect ratio). • With a video scaler, projectors and displays no have to reprocess the output to match their own native resolution, displayed image is sharper. Video scaling the intelligent way. The Intelligent Video Scaler represents the next generation in our video scaler solutions. It support for component video input and output, function of front-panel controls, and RS-232 remote of all functions. Like the Advanced Video Scaler, the Intelligent Video Scaler eliminates on-screen artifacts (such as black lines) associated with line doubler conversion. It also features selectable output resolutions and aspect control ratio. Technically Speaking The Advanced Video Scaler and Intelligent Video Scaler convert images from a TV screen onto a computer monitor, LCD, or plasma screen. Here’s more about how they work. Types of signals. TV video is defined by either the NTSC, PAL, or SECAM standard, which dictates the number of lines in the picture, how the color information is defined, and the speed with which the lines are painted on the screen (refresh rate). But within NTSC, PAL, and SECAM, there are several formats that meet these standards. Composite video is most commonly used, with video information for red, green, and blue (RGB) and sync combined into a single signal. S-Video, which separates the chrominance (color) from the luminance and sync information, provides a superior picture. AC217A also supports component video, which carries the color and brightness portions of the video signal as separate signals. This provides superb color clarity and reduced color bleeding. How they work. The Video Scalers will accept any video source, de-interlace it with proprietary, advanced motion compensation, and then intelligently scale it to the desired resolution with virtually no artifacts. All you need to do is set the output resolution to match the native resolution of the connected LCD, DLP, or plasma projector or display. 724-746-5500 blackbox.com 2of 3 #20510 3 of 3 7/3/2007 #20510 724-746-5500 blackbox.com TECH SPECS Controls — AC215A: Contrast, brightness, saturation, hue, horizontal and vertical AC217A: Input selection, ratio conversion Input Decoding — AC215A: 8-bit Y, 8-bit C, and 16-bit YUV with comb-filter processing; AC217A: 16-bit YUV with adaptive 4H comb-filter processing Input Formats — Normal (4:3), Letterbox (16:9) Input Types — AC215A: Composite and S-Video (Y/C), both terminating into 75 ohms; AC217A: Composite, S-Video, (Y/C), both terminating into 75 ohms, component Input Video Standards — AC215A: NTSC, NTSC-Japan, PAL (B, D, G, H, I, M, N, N-3.58), SECAM; AC217A: NTSC, PAL (B, G, H, I) Output Resolutions — AC215A: 640 x 480, 800 x 600, 832 x 624, 852 x 480, 1024 x 768, 1280 x 1024 (60 Hz only); AC217A: 480p, 720p, 1080p, 1280 x 1024, 1366 x 768 Aspect Ratio Conversion — AC217A: 4:3 to full screen, 4:3 to 4:3 in 16:9 screen, 16:9 to 16:9 Switch — AC217A: Selects output format RGBS, or YCBCR Connectors — AC215A: Input: (1) Composite: BNC F; S-Video: (1) 4-pin mini-DIN F; Output: (1) HD15 F with standard VGA pinout, configurable as RGBHV, RGBS, or RGSB (RGB Sync on Green); AC217A: Input: (1) Composite: RCA F; S-Video: (1) 4-pin mini-DIN F; Component: (3) RCA F; Output: (1) HD15 F standard VGA pinout; RS-232 remote: (1) 3-pin screw terminal Power — AC215A: 95 to 250 VAC, 47 to 63 Hz, autosensing, external; AC217A: 85 to 265 VAC, 47 to 63 Hz, autosensing, internal Size — 1.5"H x 7.3"W x 8"D (3.8 x 18.5 x 20.3 cm) Weight —...
