10.4 CVBS
The CVBS screen enables you to set up and view options for a video input source and the
video output signal. CVBS provides options for the two composite video input/output slots (if
the CVBS option is fitted).
Composite encoding and decoding options will have been chosen at the time of product
purchase. Y/C decoding is also available.
10.4.1 CVBS Decoder
Each slot has two composite video connections.
•
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 contains the input composite signal.
•
Input 2:
Connection A2 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.
Note:
The unit automatically detects the input standard.
