for details.
G.4.7
Mux Setup
On the MCE, the Mux Menu can be used
for controlling output bit-rate and
remultiplexing control, (if fitted).
1.
From the summary screen press
Menu, Setup, Mux.
2.
From the Mux screen press:
a)
O/P Format – select either 188
or 204 Byte Mode.
b)
Bit-rate – entry of the bit-rate
in 188 or 204 Byte Packets.
NOTE…
The Modulator can be controlled by either
entering the bit-rate in 188 or 204 Byte packets
or the symbol rate.
G.4.8
Remultiplexing
Setup Option
On the MCE, the Remultiplexing Module
(if fitted) is controlled using two menus.
To set up services use the Services
Menu: Error! Bookmark not defined.
1.
From the summary screen press

If other encoders are connected to the ASI inputs
of the remultiplexer card, then their services will be
combined with the local service, to form a ‘multiple
channel’ service. The service names of the
additional channels will appear in the list as shown.
The spare bit-rate indicator graph (on the service
screen) should be used to ensure that the transport
stream has not being saturated with data.
