Total transmitted bitrate
To view the total transmitted bitrate in Mbit/s there are two options:
1.
See main screen
2.
Using Up and Down buttons, go to line no.10 in the Monitor menu.
The measure displays the transmitted total bitrate which consists of: video
bitrate, audio channels bitrate, data channel bitrate and SI tables.
The total bit rate is determined by constellation scheme, guard interval,
convolutional code, bandwidth (6, 7 or 8MHz) and other COFDM system
specific parameters as Reed Solomon code.
