Stream View

Change Bar

The variation of bit rate in each PID is indicated by a Change Bar (except when PID Variability is selected). The ends of the Change Bar show the maximum and minimum values of the bit rate since monitoring started or since the change bars were last reset.

Change Bar

The Change Bar on all PIDs can be reset by selecting the Reset Change Bars button at the top of the PIDs screen.

Bit Rate Limits

For each PID you can set a minimum () and maximum () bit rate limit. If the incoming bit rate falls outside the values that have been set, an alarm is indicated on the screen by the graphical bit rate bar changing from green to red or yellow; the PID Occupancy test on the Tests view is also set. This test can also activate the external alarm outputs. When enabled, the limits appear as in the following diagram:
