Scaling with Speed and Agility
A new generation of Scalers
ANNUAL
CONFERENCE
tvONE’s evolutionary development of our renowned CORIO®2 scaler technology continues
to provide commercial integrators with unsurpassed image quality in nearly any installation
situation. Now, to further improve upon the core technology, we are introducing a new generation
of scalers that are extremely intuitive & user-friendly and provide greater fl exibility.
These new designs have more input/output fl exibility than any other
previous tvONE scaler. They can be set up and managed using a new,
innovative front panel or via computer-based control panel that allows
setup in less than / the time of the previous generation. The interface
provides two distinct sections for unrivaled ease of use; one for system
setup and another for live, real-time operations. The front panel
helps with setup time through color modulated soft-buttons, intuitive
categorized menus, and simple recall of up to 12 presets. Control
software is available on several Windows platforms & interfaces
directly with the unit. IP and RS-232 serial interfaces are also provided
for use with 3rd party control systems.
These scalers provide high quality bi-directional conversion between a
variety of analog and digital video formats. Inputs and Outputs include
SD/HD/3G-SDI, HDMI, DVI, Composite Video, YC, YUV, YPbPr or RGB.
Signal parameters of the incoming video may be adjusted. All settings
are stored in non-volatile memory and are retained even when power
is switched o . Twelve user-defi ned presets are available to customize
settings for various applications. The high resolution RGB/YPbPr output
is selectable at virtually any PC or HDTV resolution. NTSC, PAL, PAL-M,
and PAL-N standards are supported. SECAM is supported for input.
tvONE’s Calibrate feature automatically sizes and positions computer
images to fi t exactly on the video display, and the 10X Variable Zoom
can enlarge and position any part of an input to fi ll the entire video
output display. Variable Shrink with as much as 90% size reduction
allows almost any image to fi t on the tiniest screen. Both high sampling
rate and the advanced Digital Flicker Elimination circuitry on CV &
YC outputs ensure crisp, clear images, while full bandwidth chroma
sampling ensures faithfully reproduced, high resolution colors. Motion
compensation, diagonal interpolation and a 3:2 Pulldown feature for
NTSC greatly improve the image quality. Temporal interpolation greatly
improves frame-rate conversion by merging successive frames. Pixel
Level Motion Adaptive Diagonal Interpolation ensures high quality deinterlacing of PAL & NTSC signals.
CORIOcontrol software
encompasses the C2-2855
Universal Scaler, the
C2-2755 Video Scaler
and the C2-2655 Scan
Converter. Adding
even more fl exibility,
CORIOcontrol is a PC
based application that
gives you full remote
access, o ering remote
management of system
settings and control
confi gurations before and
during live presentations.
The software consists of
a number mini applications that allow
you to access separate elements of
the C2-2x55’s functionality. These
combine to give you a full suite of control interfaces all in one convenient
application. The mini apps allow you to: upload and manage internally
stored Still images and Logos; store and recall Presets; edit resolutions;
manage system confi gurations; update fi rmware; and backup and restore
system settings. Connection can be via RS232 or Ethernet adding extra
fl exibility for local and remote access. The communications interface
e ciently analyses both the network and the host PC and displays all
available com ports and IP connected units regardless of their address,
making it easy to manage network connectivity and hardware devices.
Pixel mode
Advanced Features - Keying allows one input to be keyed over a second
input. The keyed image may be faded in and out. Due to the 4:4:4
sampling format for RGB sources, precise keying at the pixel level can
be achieved. Transitions permit Seamless Cut, Fade or Wipe transitions
between input sources. The Picture-In-Picture (PIP) functionality allows
an input to be inset in a window over a second input or vice versa. The
PIP window may be placed anywhere on the screen. The Genlock feature
ensures precise synchronization of the incoming signals by providing a
wide subcarrier lock range with subcarrier phase adjust.
Basic 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
allow s any audio input to be embedded on all outputs which support
embedded audio data (HDMI/DVI-U/SDI).
Auto Switching
The Auto Switching function turns the C2-2x55 into a powerful
standalone device. Allowing the user to connect their source and have it
automatically displayed on screen without having to press any buttons.
The incoming resolution is quickly detected and analysed meaning
within a few seconds the user is up and running and ready to present.
This is particularly useful in situations where there is little or no technical
supervision such as in meeting rooms, medical environments, teaching
spaces or live staging events.
NEW - Pixel mode
allows for exact
placement of
window locations
and sizes.
