10.4.1 CVBS Decoder A–D
•
Source:
Use to select a video input source. If using a composite source, only one of
the two CVBS connectors are used.
•
Input 1:
Connection A1, B1, C1, or D1 contains the input composite signal.
•
Input 2:
Connection A1, B1, C1, or D1 contains the input composite signal.
•
Y/C:
When using Y/C signals both composite connectors are used, so this option
must be selected.
•
ACC:
The Automatic Chroma Control (ACC) examines the input burst amplitude and
adjusts chrominance gain to compensate for chroma level attenuation.
Note: Use this control when chroma levels are low compared to luminance. This may
occur when using YC installations or composite from RF links
.
•
CTI:
The Chroma Transient Improver (CTI) examines the input video data. CTI
detects transitions of chroma and enhances chroma edges in order to artificially
restore lost color bandwidth.
Note: Use this control when the input video has chroma bandwidth limitations.
•
Pedestal:
When turned on, allows the composite source (NTSC only) to be treated as
if a pedestal is present.
•
NTSC Hue:
Adjusts the NTSC hue to correct tonal color changes.
10.4.2 CVBS Encoder A–D
Each slot has two composite video connections.
•
Source:
Use to route a processing channel to the chosen CVBS encoder.
•
Format:
Specifies the CVBS output standard. The options are:
•
PAL/NTSC
•
PAL-M/PAL-N
•
PAL/NTSC-J
10.4.3 Routing a Processing Channel
To route a specific processing channel output to a CVBS output:
1.
From the System menu list, select CVBS.
2.
Under CVBS Encoder A (or B, C, D) > Source, choose the processing channel you
want to route to this slot.
3.
Under CVBS Encoder A (or B, C, D) > Format, choose the format of the composite
output.
For example, to create a PAL composite output on slots C1 and C2 where the converted
output has been downconverted using processing channel 2:
1.
Under CVBS Encoder C > Source, select Ch2.
2.
Under CVBS Encoder C > Format, select PAL/NTSC.
Note:
The unit automatically detects the input standard.
Note:
If an illegal signal such as HD video is routed to a CVBS encoder, there will be no output
signal from this connector.
