tvONE C2-2755

The C2-2755 Video Scaler PLUS is one of a new generation of high performance scalers that provides best-in-class video scaling and format conversion along with revolutionary, intuitive user interface tools. The crystal clear OLED display intuitively guides users through setup and control using color-modulated, backlit buttons. Alternatively, a graphic user interface† for Windows can be used to set up and control the unit remotely via IP. RS232 is also provided as a direct control interface for 3rd party control systems. The video performance of the C2-2755 is based on tvONE's exclusive CORIO®2 technology, which provides high quality bi-directional conversion and switching between a wide variety of Analogue and digital video formats. Living up to its designation as a “Video Scaler” the C2-2755 supports SD/HD/3G-SDI, HDMI, DVI, Composite Video, YC, YUV, YPbPr or RGB, on inputs and HDMI and DVI-I outputs, and the signal parameters of the incoming video may be adjusted. The high resolution RGB/YPbPr output is selectable at virtually any PC or HDTV resolution. Crisp, clear images are ensured by a high sampling rate and advanced Digital Flicker Elimination circuitry on CV & YC outputs, while full bandwidth chroma sampling ensures faithfully reproduced, high resolution colors. Motion compensation, diagonal interpolation and a 3:2 Pull-down feature provide for the best possible NTSC image quality, while temporal interpolation refines frame-rate conversion by merging successive frames

Designed for commercial 24/7/365 use. Twelve user-defined presets are readily available for instant, on-the-fly adjustment to diverse customized applications. tvONE's Calibrate feature automatically sizes and positions computer images to fit exactly on the video display, and the 10X Variable Zoom can enlarge and position any part of an input to fill the entire video output display. Variable Shrink with as much as 90% size reduction allows almost any image to fit on the tiniest screen.

Advanced Features - Keying allows one input to be keyed over a second input. The keyed image may be faded in and out. Precise keying at the pixel level is possible due to 4:4:4 sampling format for RGB sources. Transitions permit Seamless Cut, Fade or Wipe transitions when switching between input sources. Picture-In-Picture (PIP) functionality allows an input to be inset in a window over a second input or vice versa, and the PIP window may be placed anywhere on the screen. Genlock ensures precise synchronization of the incoming signals.

Audio - Integral Stereo Audio switching is provided by an integral 4x1 audio routing switcher. The four impedance-independent unbalanced inputs follow the video input selection. A rear panel terminal block and a 3.5mm jack-socket provides access.

Embedded Audio Support allows any audio input to be embedded on all outputs which support embedded audio data (HDMI/Universal DVI/SDI). The unit is housed in a desktop case and can be rack-mounted with an optional 19-inch rackmount kit that holds one or two units.
