C2-2855 Universal Scaler PLUS is first in 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 colour-modulated, backlit buttons.

Alternatively, a graphic user interface for computer or tablet 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 C2-2855 is based on tvONE's exclusive CORIO®2 technology, which provides high quality bi-directional conversion and switching between a wide variety of analog and digital video formats. Living up to its designation as a "Universal Scaler" the C2-2855 supports SD/HD/3G-SDI, HDMI, DVI, Composite Video, YC, YUV, YPbPr or RGB, on both inputs and 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 and NTSC, PAL, PAL-M, and PAL-N standards are all supported. 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 colours. 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.

Auto Switching
The auto-switching function turns the C2-2x55 scaler series into powerful standalone devices. It allows users the ability to connect their source and have it automatically displayed on a screen without having to press any buttons. The incoming resolution is quickly detected and analyzed meaning within a few seconds the user is up and running and ready to present.

This function is particularly useful in situations where there is no control system or technical supervision such as in meeting rooms, medical environments, teaching spaces or live staging events.

Designed for commercial 24/7/365 use, the C2-2855 automatically stores all settings in non-volatile memory for automatic restoration of the most recent settings even when power is switched off. Twelve user-defined presets are readily available for instant, on-the-fly adjustment to diverse customized applications.

tvONE's AutoSet 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/DVI-U/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.

New launches at ISE 2020

Here's an overview of our vendors exhibiting at ISE 2020. Please call us on +44 (0)1457 851000 if you would like to book a stand tour with one of our manufacturers. BLACKMAGIC DESIGN HALL 3, STAND C140 The Video Assist 12G 5” and 7” monitor recorders are now shipping. The original HD versions were incredibly popular with AV technicians who wanted to verify SDI and HDMI feeds and check waveform levels. For production teams, their 4K HDR capture makes them a superb on-camera SD card recorder. The ATEM Mini is a very small, cost-effective 4 channel HDMI video switcher with streaming output. Great as a portable mixer or a signal switcher, it’s being adopted by everyone from conference producers to AV technicians looking for simple HDMI switching.

Blog: why is this scaler proving so popular?

TVOne's flexible, new Corio2 C2-2855 Universal Scaler is proving very popular.  Why? Everyone can think of a middling CEO following on from a great one (Microsoft), or an average product replacing a winner (Nintendo). When a product does badly in the market, the boards is quick to dissect what went wrong. But let’s see the glass half full: tvONE’s C2-2855 has been an instant success. Why is that?
