Parameters
Rate Control
Select the output rate control.
Auto - The output rate follows that set by
the uplink. This setting can be used if the
signal source is ASI. If Insert Null Packet is
set to Yes, the output bit rate is the same as
the input rate (including all the null
packets). If Insert Null Packet is set to No,
the output rate is equal to the payload rate
of the transport stream to be encapsulated,
and in most cases, it will be lower than the
overall input rate.
User - The output rate is specified by the
User Rate (Mbps) parameter. It is
determined by the user setting, regardless of
the input source. Null packets are always
inserted when the configured output bit rate
is higher than the payload rate of the
transport stream to be encapsulated.
SFN Units Only:
Auto - Sets the output rate at 32 Mbps for
DVB-T transports without null packet
stuffing. If the incoming rate is lower then
32 Mbps, the receiver will burst up to 32
Mbps, but will average to the incoming bit
rate.
User - The output rate is specified as the
Output Rate parameter with null packet
stuffing disabled. The output rate must be
set high enough to pass the entire transport
or the output will be corrupted. If the
incoming rate is lower then the set output
rate, the receiver will burst up to the output
rate, but will average to the incoming bit
rate.
User Rate(Mbps)
If the Rate Control is set to
User, set the maximum output
bit rate. If null packets are
inserted, this will be the output
rate.
This setting is used when the
signal source is RF or ASI and
allows you to set the output bit
rate to a value expected by
equipment connected to the ASI
output.
0 to 206 Mbps
Note: Output data may be lost if this bit rate
is set to a value less than the actual signal bit
rate.
