# Sophia.net Signalling
|
|
|
|
When either a Private Data Descriptor or a Registration Descriptor with the value "0x534f5048" is found in any table
|
|
the following Signalling applies:
|
|
|
|
## Stream Types in PMT:
|
|
|
|
|Stream Type|Interpretation |
|
|
|0x80 |TBS 6903-X GSE Packets |
|
|
|0x81 |AC-3 Audio |
|
|
|0x82 |PID only used for PCR |
|
|
|
|
## Descriptors:
|
|
|
|
Sophia.net employs the following descriptors:
|
|
|
|
|Descriptor |Interpretation |
|
|
|0x80 |Encapsulated Transport Stream over MPE |
|
|
|
|
### 0x80: Encapsulated Transport Stream over MPE
|
|
When the following conditions all apply:
|
|
- This Descriptor is encountered in the inner loop of a PMT
|
|
- The Stream Type is 0x0D (data broadcast)
|
|
- A data_broadcast_id_descriptor is present
|
|
- data_broadcast_id is 5
|
|
THEN: This PID will contain an Encapsulated Transport Stream carried within MPE Packets.
|
|
|
|
Data within this descriptor should be a human readable description of what the Encapsulated Transport Stream is, but can be left empty.
|
|
|
|
|
|
## Other Rules:
|
|
|
|
Aside from that, the following rules shall apply:
|
|
|
|
* The IRD MUST process any TDT/TOT tables, regardless of whether the Transport Stream ID and Network ID is known or not. |
