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.  

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 

all determine the number of carousels, applications, and modules that the 

TSBroadcaster can support. 

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 

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. 

The TSBroadcaster typically supports less than 20 carousels per service and 50 

carousels per stream. 

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 

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.
