1. CP-251F not only is a video scaler it is also a scan converter and a format transformer.
2. The resolution of any PC or HDTV inputs can be scaled up or scaled down to any
other PC or HDTV resolution, along with its frame rate converted to a selectable
frequency.
3. 48 MB frame memory for frame rate conversion.
4. Signal format conversion between RGBHV and YPbPr.
5. Input: PC(VGA/SVGA/XGA/SXGA)+
HDTV(480i/576i/480p/567p/720p/1080i), Fv: 60 to 85 Hz
Output: PC(VGA/SVGA/XGA/SXGA)+
HDTV(480p/576p/720p/1080i)
6. Input mode auto detection.
7. Input Setup allows for fine-tuning the output picture to a best
condition through the adjustment of ADC sampling clock, and phase.
8. Easy- to- use push buttons and OSD menu control.
Input connection:
The CP-251F can accept both PC and HDTV inputs.
When accepting a PC input use the 15-pin D-sub cable to connect the output of a PC
device to the input connector labed PC/HDTV on the back of CP-251F.
When accepting a HDTV input use the 15-pin D-sub to YPbPr/3 RCA cable to connect
the YPbPr/output (or YCbCr) of a HDTV device to the PC/HDTV input connector
of the CP-251F.
The CP-251F can automatically detect the mode and resolution of the PC/HDTV input.
Output connection:
The CP-251F can output a variety of PC resolution and HDTV progressive resolution.
When one of the PC resolution is selected as output, use the 15-pin D-SubVGA cable to
connect the PC/HDTV output of the CP-251F to the VGA input of a display monitor.
When one of the HDTV resolution is selected as output, use the 15-pin D-Sub to
YPbPr/3 RCA cable to connect the PC/HDTV output of the CP-251F to the YPbPr
input of a HDTV device.
Note:
Use of wrong cable for your selected output will result in an abnormal picture on the
screen.
