Video Switcher/Scalers
Models C2-2200, C2-2205, C2-2250, C2-2255
C2-2200 Video Switcher/Scaler is based on TV One’s
exclusive CORIO2™ technology and provides high
scaling to Analog or DVI Computer or HDTV signals.
NTSC and PAL video standards are supported. Video
Inputs are 2x Composite, 2x S-Video and 1x YUV
Component or YPbPr. A computer bypass is also
provided. RGB/YPbPr Scaling permits the computer
input signals to be scaled with the same flexibility as the
video inputs. The output is selectable as any computer
resolution up to 2048x2048 at any vertical refresh rate
and all HDTV resolutions up to 1080p. A wide variety of
computer signal formats are available to support PC,
Mac and Workstation formats. C2-2205 provides an SDI
Input as well all the other features of the C2-2200.
All the functions can be controlled via the front panel
Push Buttons, an Infrared Control Remote Unit or via an
RS-232 or IP connection. A Windows Control Panel is
provided and most third party control systems interface
directly with the entire C2 range of products. A front
panel LCD makes setup easy.
Variable Zoom to 10X allows you to enlarge any part of
the video image to fill the entire computer screen and
position controls allow you to move around 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 res colors.
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 provides access.
C2-2250 Video Scaler PLUS has all the functions and
features of the C2-2200 and adds a wide variety of
additional capabilities, including Picture-In-Picture,
Chromakey, Lumakey and Mixing. The Key Mode allows
computer graphics to be keyed over an external
Composite or S-Video signal or visa versa. 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 glitch-free mixing
between the computer image and external video. The
PIP Mode allows either of the computer inputs to be
inset in a window over either of the video inputs.
C2-2255 provides an SDI Input as well.
