The easiest way to configure the bit-rates to avoid overflow, is as follows:
1. Divide the 188 byte output bit-rate of the primary (master)
remultiplexing unit, (this can be found in the
Setup/Mux/Remux
Module/Output Bit-rate
), by the number of contributing services
(including the primary service). Such that:
O/P Rate (188) / N = Host Rate (188)
[Where N = number of services to be combined including
primary]
2. Then set the Host Rates (188) of each contributing unit and the master
unit to equal the calculated Host Rate.
If the above procedure is followed, an equal bit-rate is allocated to each
contributing unit. By setting the host rates, the video and audio bit-rates
will be automatically adjusted to suit.
The amount of spare bit-rate and input bit-rate that has been used in the
Remultiplexer can be monitored using the bar graph indicators in the
Setup/Mux/Remux Module
Menu
.

What to do if Overflow Occurs
If an ‘Overflow Error’ is indicated on the equipment, then the incoming
contributing bit-rate exceeds the outgoing bit-rate. To avoid corruption
reduce the incoming bit-rate by either removing services, (turn the service
Off or remove the ASI input), or reduce the bit-rate of the incoming
service.
