MPEG Audio.
Multiplex Occupancy
A graphical representation of the PID bit rate. The bar color
indicates the error status of the PID. Superimposed on the
bar are the Change Bar and (where set) the limits (see Clear
Limits below). The graphic is displayed in the color
according to whether there are any PID errors (if a set limit
has been exceeded).
Note that the graphical representation and section Title bar
is changed when PID Variability is selected (see Test
Selection, see page 3-40).
Bit Rate The PID bit rate in bits per second.
Buttons
Reset Change Bars Resets the Change Bars of all programs.
Clear Limits * Resets and disables the Bit Rate Limits of all programs.
User PIDs Allows you to add PIDs to the displayed list.
Reset All Resets the selected test for all PIDs.
* - only displayed if Bit Rate Testing (Option 05) is licensed for use.
The Stream Bit Rate shows the sum of the individual PID bit rates that make up
the stream. The PID bit rate (Bit Rate) shown for each PID is that for the
individual PID.
Only users logged on as Administrators can adjust bit rate limits.
