Aspect Ratio Configuration Process
When fitting the received Video signal A/R to the monitor A/R, the following
three IRD-2900 parameters values must be set to achieve the required
conversion:
• WSS
• Monitor Aspect Ratio
• Interpolation
WSS (WIDE SCREEN SIGNALING)
The purpose of the WSS signal is to inform the destination monitor of the
received Video A/R. The IRD-2900 extracts the WSS information from an
operator-selected source, generates a new WSS signal (see ‘WSS Signal
Generator’ in Figure C-1), and outputs it to the monitor.
The WSS menu in the IRD-2900 contains two items:
• Source – from which the IRD-2900 extracts the WSS information. The
available options are: DISABLE, TV MONITOR, E.S. (EN-301-775), and
VIDEO (see WSS explanation in Section 4.2.6.2 for further details).
• Line1 – Video line into which the IRD-2900 inserts the generated WSS
signal (see WSS explanation in Section 4.2.6.2 for further details).
MONITOR ASPECT RATIO
This parameter informs the Conversion Machine of the destination monitor’s A/R.
This is one of two parameter values which the Conversion Machine needs for its
operation (see Figure C-1).
