MTM400 MPEG Transport Stream Monitor User Manual 
Monitoring Overview Screen (Summary Screen) 
This screen provides a dynamic visual overview of the stream and monitoring 
status. The information is updated at regular intervals. 
 
Figure 3-7: Stream view - Overview 
The upper half of the Overview screen displays service information in the form of 
a pie chart and a list. Services are named and color coded to allow correlation 
between the pie chart and the list. The pie percentage value of the NULL PID 
relates to the stream bitrate. The services are divided pro-rata over the total 
effective bitrate of all the active services in the stream (due to PID reuse the total 
effective bitrate may be greater than the transmitted stream bitrate), this ensures 
that the NULL PID bitrate shows the true available bandwidth. Bit rates of 
individual services are given in the service list. The icons in the service list give an 
indication of the program content: video, audio or data.
