The TSBroadcaster
Functional Overview, Continued
The TSBroadcaster provides password-protected user accounts that control access to
the system and allows you to manage the event log and Transport Stream build
records.
How Much Data Can the TSBroadcaster Support?
The practical limits provided in this section revolve around the size of the content
and the performance required at the limit. So the numbers that we provide are limits
of practical performance rather than absolute limits. The limit in any real case will
depend on its individual characteristics.
The available bandwidth, file size, CPU usage, and the required time to deliver a file
The available bandwidth, file size, CPU usage, and the required time to deliver a file
all determine the number of carousels, applications, and modules that the
TSBroadcaster can support.
Number of Supported Streams
For a TSBroadcaster/TSPlayer on a single machine there is only a single ASI output,
thus limiting the number of supported streams to 1. Additional TSPlayers are
needed to increase the number of supported streams.
Out-of-band transport streams are generated automatically to hold a carousel
Out-of-band transport streams are generated automatically to hold a carousel
marked as “out-of-band.” The TSBroadcaster supports a single out-of-band object
carousel only, in accordance with the OCAP specification 22.2.2.1. A separate
transport stream is used for inband data.
Number of Supported Carousels
The TSBroadcaster typically supports less than 20 carousels per service and 50
carousels per stream.
Number of Supported Applications
There is no limit to the number of applications defined in the TSBroadcaster,
although the time taken to retrieve the model will increase with the overall size of
the application content.
Currently, the TSBroadcaster supports less than 20 applications per service, 100
Currently, the TSBroadcaster supports less than 20 applications per service, 100
applications per stream, and applications as large as 10 MB. The size of the
application that you can use depends on the capability of the receiver. The
TSBroadcaster can support any acceptable file types that the application supports.
