TSBroadcaster
provides facilities to set up and manage transport stream
definitions. TSBroadcaster generates MPEG
transport streams containing the following components:
-
One Program Allocation Table (PAT) - the PAT references the PMT of
each service
-
One Program Map Table (PMT) per program/service - the PMT references
-
the object carousels allocated to the service
-
the AIT for the service
-
the elementary stream defined by the stream event channel
-
the components of the AV content selected for the service
-
One Application Information Table (AIT) per program/service
-
Zero or more DSM-CC Object Carousels
-
Optional elementary Stream to carry DSM-CC Stream Events
-
AV content - the AV content defines the characteristics of the audio and
video components multiplexed into the transport stream, thus allowing them
to be referenced from PMTs
A TSBroadcaster installation supports one of two different types of
transport stream:
DVB and OCAP. The TSBroadcaster licence and the
TSBroadcaster data that is installed determine the type
of transport stream that is supported.
Transport streams generated by TSBroadcaster contain the
following additional components:
| DVB | OCAP |
-
Service Description Table (SDT)
-
Network Information Table (NIT)
-
Optional Time and Date Table (TDT)
|
-
Optional Master Guide Table (MGT)
-
Optional Long-form Virtual Channel Table (LVCT)
-
Optional System Time Table (STT)
-
Optional Extended Application Information Table (XAIT)
|
When the definition or a transport stream is modified, TSBroadcaster
immediately regenerates it to match the new definition.
The version numbers of the tables in the transport
stream are automatically incremented to reflect the changes.
TSBroadcaster needs specific DVB or OCAP information about the transport
stream and the services carried in it to be able to produce the DVB or OCAP
tables. To do this, it provides different interfaces for stream and service
management for DVB and OCAP versions.
Users with ManageStreams privilege have access to the stream
management functions through the Internet browser UI. These users
can select the Streams button from the navigation bar and are presented
with the Manage All Streams Page. This page shows
transport stream definitions with a set of buttons to manage them.
