Understand Direct ADSG 

Direct ADSG can be provisioned in the following environments: 

 

SARA: broadcast data is sent out-of-band from the Broadcast File System (BFS) 
object carousel directly over a CMTS or QPSK bridge directly to host devices 

 

tru2way and other Third-Party Navigators: broadcast data is sent out-of-band 
from a third-party application object carousel (for example, TSBroadcaster) over 
a CMTS or QPSK bridge directly to host devices. For details about third-party 
applications, please refer to the documentation that accompanied the application. 

Note: When provisioning direct ADSG with a third-party application, you must link 
the application to ADSG using the ADSG Application window on the DNCS Admin 
Console. Refer to Defining a Third-Party Application for ADSG (Optional) (on page 
15) for details. 

To successfully reach each ADSG-compliant host device, broadcast data must be sent 
in a format that includes the following criteria: 

 

A broadcast tunnel header 

 

An accurate virtual channel to source ID (derived from the CableCARD Channel 
Map file) 

 

Non video/audio sources defined as hidden 
Note: For more information about hidden channels, please refer to Configuring
