4.9.3 Remux Module
When the Remux option module M2/EOM2/REMUX is fitted, there is an additional item (
Host
Bitrate
) in the
Mux Menu
and a further
Remux Module Menu
and
1.Service Menu
.
Table 4.30: Remux Menu Options
Selected Item Options Description
Update PIDs from I/Ps In this mode, only changes at any of the Remux inputs (e.g. PID change, new
component appears) will always be passed through to the output and the
outgoing PSI tables change accordingly.
Lock PID Mapping In this mode, changes at the Remux inputs will not be recognised. The
outgoing PSI tables will also not change. This can result in TS errors being
flagged by an analyser, e./g. if a component disappears from an input. It will
remain mapped through and referred in the PSI tables which will result in
“Packet Missing” warnings from the analyser.
PID Lock Power Up
Delay Option This option only appears in Lock PID Mapping mode, It is designed to give
the Encoder time after power up to acquire the services at its Remux input
before it is locked-down..
PID Remap Status
This option only appears in Lock PID Mapping mode. It indicates whether the
power-up delay has expired and lock-down has occurred.
PID Remap:
This option allows the action taken
during PID Remapping to be
tailored.
New Services Default This specifies whether new services detected on a Remux input will be ON (i.e.
mapped through) or OFF by default. (If PID Remap Status has reached the
LOCKED stage, new services will not be recognised at all.) A service is
deemed to be new if, on power-up, the acquired PSI shows that there is any
differences to the make up of the services. In a multi-level Remux system, if an
upstream Encoder is power-cycled, the downstream Remux Encoder may
detect the service as NEW due to the way the PSI is built during power-up.
Therefore it is recommended that the New Services Default be set to ON
unless there are particular concerns about services causing an overflow.
188 bytes Uses 188 byte packet format.
Packet Length:
This option enables the Packet
Length to be set.
204 bytes Uses 204 byte packet format.
bitrate
bitrate (188):
Min: 0.0000 Mbit/s
bitrate (204):
Max (without Remux):
110.0000 Mbit/s
Max (with Remux):
50.0000 Mbit/s
Step Size:
0.0001 Mbit/s
Both the bitrate (188) and the bitrate (204) can be in the range of 0 Mbit/s to
110 Mbit/s.
Changing the bitrate affects the automatic video bitrate and video resolution
calculations.
If the specified bitrate is outside the valid input range, a confirmation screen is
displayed which shows the maximum/minimum value allowed.
Multiplexer output bitrate when in
baseband output format and ASI
output mode.
If the Packet Length option is set to 188 bytes then only the bitrate (188) option is displayed. If the
Packet Length option is set to 204 bytes then both the bitrate (188) and bitrate (204) options are
displayed.
