10.4 CVBS (LC2000/LC4000 Only)
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 four 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.
The composite capability is determined by the number of processing channels and certain
hardware restrictions. The composite variants allowed are as follows:
