Universal I/O Video Switcher/Scaler

The TV One C2-2350A Universal I/O Video Switcher/Scaler is based on TV One’s exclusive CORIO®2 technology and provides high quality bi-directional conversion between a variety of video formats. Inputs and Outputs can be DVI, RGB, YUV, YPbPr, Composite or S-Video (YC). Incoming video parameters may be adjusted. All settings for the C2-2350A are stored in non-volatile memory and are retained even when power is switched off. Ten user defined presets are also available to customize settings for various applications. The high resolution RGB/YPbPr output is selectable as virtually any PC or HDTV resolution. TV One's exclusive AutoSet feature takes the hassle out of setup by automatically sizing and positioning the computer input image to fit exactly on the video screen. NTSC, PAL, PAL-M, PAL-N, SECAM standards are supported.

All the functions can be controlled via the front panel Push Buttons, Infrared, RS-232 or IP. Windows Control Panel software is provided and most third party control systems interface directly with the entire C2 range of products. A front panel LCD makes setup easy. The unit is housed in a desktop case and an optional rackmount kit is available that holds one or two units.

Variable Zoom to 10X enlarges any part of the computer screen to fill the entire video screen and position controls allow movement to any area desired. Variable Shrink to as little as 10% allows fitting the image onto most displays. The advanced Digital Flicker Elimination circuitry and high sampling rate insures crisp, clear images, while full bandwidth chroma sampling insures faithfully reproduced, high resolution colors. Motion compensation, diagonal interpolation and a 3:2 Pulldown feature for NTSC improves the image quality. Temporal interpolation greatly improves frame-rate conversion by analyzing and merging successive frames. Pixel Level Motion Adaptive Diagonal Interpolation insures high quality de-interlacing of PAL and NTSC signals.

The Key Mode allows computer graphics to be keyed over an external Composite, YC or SDI signal. The keyed image may be faded in and out. Due to the 4:4:4 sampling format, precise keying at the pixel level can be achieved. The Mix Mode permits Seamless Cut, Fade or Wipe transitions between input sources. The PIP Mode allows either of the computer inputs to be inset in a window over either of the video inputs or vice versa. The PIP window may be placed anywhere on the screen. The Edge Blending feature allows feathering any or all of the edges; multiple images can be aligned vertically, horizontally, or both to create unusual displays. Using multiple units, any number of images can be blended. Gamma correction is employed to compensate for many of the problems faced when blending projectors. The Genlock feature insures precise synchronization of the incoming signals by providing a wide Subcarrier lock range with Subcarrier phase adjust.

Input Expansion is possible by using the optional S2 Series Input Expansion Switchers for SD/HD-SDI, DVI, RGB, YPbPr, YUV, Composite or YC. These units link to C2 unit via an OPTIONS Interconnect Cable and become an integral part of the main unit from a control and operational standpoint. The routing of these additional inputs is controlled directly from the control system of the C2 unit. Multiple different S2 models may be simultaneously connected to a single C2 unit.
