CP525 cMux User’s Manual Rev. 5.20.12 (3944) ID: um_tsmux
The formula for remapping of service ID values are described below. If Service ID is already
taken, the next available Service ID value within the Service ID range will be used.
Service ID value = ’Start SID’ + (’Port Index’ x ’Port Offset’)
Here the ’Port Index’ starts at index 0 for ASI 1, 8 for IP 1 and 24 for Switch 1.
The default configuration has ’Port Offset’ set to 10. By using this setting there will be room
for 10 service IDs per port. If back-to-back operation is wanted between service IDs from each
port, a value of 0 or 1 could be used.
An example with settings and values are given below:
Input ports: ASI 2 (Port Index 1), ASI 4 (Port Index 3). Assuming 2 services on each input.
Auto-remap service IDs: Always
Rule type: TV
Start ID: 1
Stop ID: 200
Port Offset: 5
The resulting service ID remapping from ASI2 would be:
First TV service ID: 1 + (1 x 5)
= 6 (Service 1)
Second TV service ID: 1 + (1 x 5) = 6 (Service 2). This will be further be mapped to
service ID 7 since service ID 6 is occupied by Service 1.
The resulting service ID remapping from ASI4 would be:
First TV service ID: 1 + (3 x 5)
= 16 (Service 1)
Second TV service ID: 1 + (3 x 5) = 16 (Service 2). This will be further be mapped to
service ID 17 since service ID 16 is occupied by Service 1.
The end result will be four TV services transmitted by the multiplexer at the following IDs:
Service 6 (ASI2 - Service 1)
Service 7 (ASI2 - Service 2)
Service 16 (ASI4 - Service 1)
Service 17 (ASI4 - Service 2)
In the case where the amount of remapped service IDs exceed the configured range defined by
the rule types, the multiplexer will try to keep the original service ID values on the remaining
un-remapped service IDs. If this creates a service ID conflict an alarm will appear on the
multiplexer output.
Auto-remap service IDs
This parameter controls enabling and disabling of automatic service remapping. Three
options are available, “Off”, “Always” and “On Conflict”.
Parameter selection “Off” will disable automatic remapping, and the rule types will not be
processed or taken into consideration.
Parameter selection “Always” will always try to fulfil the configured remapping rules
specified, including handling of service ID conflicts.
Parameter selection “On Conflicts” will only remap service IDs if service ID conflicts are
detected during the multiplexing operation. In this case the first occurrence of the service
ID will remain at original service ID value while following occurrences will be remapped
according to the specified rules.
Keep last remap
If enabled and there is a change on the input signal(s), the last Auto-Remapped Service
