Special Control Considerations
Unlike SD-SDI inputs, only a single analog video source can be
auto-detected. Therefore, you must pre-select the desired analog input
video source (composite, S-video, or CAV) in order for the
auto-detection to work across the HD-SDI/SD-SDI/analog inputs. To
select a desired input, follow this path through the menu structure:
Video Setup>Analog Input>Analog Video Source.
Additionally, set the I/P Video Mode parameter to Auto Detect.
For more information, see “Input Video Modes” on page 102.
