Field and frame line numbers depend on the video format the switcher is operating in. If the switcher is operating in a Progressive Scan video format, no even or odd information is displayed.
Ancillary data parameters are set independently for each video format. Changing video formats recalls the last saved parameters for the selected video format.
Tip: Refer to To Edit a MultiViewer Layout for information on setting the ancillary data source
