Rate Control
User Rate(Mbps)
116
Description
Select the output rate control.
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.
Parameters
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.
Single Frequency Network (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 than 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 than the set output rate, the
receiver will burst up to the output rate, but
will average to the incoming bit rate.
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.
