The TSBroadcaster supports playout of local audio and video (A/V)  content to 

provide context for development, testing, and demonstration. 

To make the TSBroadcaster play out A/V content, you must take the following steps: 
• 

Procure the A/V content you want to play out 

• 

Configure the system to play out the A/V content 

• 

Configure the system to reference the A/V content 

Several independent sets of A/V content may be added to the output. 

The TSBroadcaster requires the A/V content as a file containing a constant bit rate 

stream of 188 byte Transport Stream packets. The stream must contain one or more 

elementary streams carrying A/V components, with PCR embedded in at least one 

component. The stream can be an SPTS, an MPTS, or simply the selected 

components on their own. 
The A/V content may be captured from the output of a digital broadcasting system 

or generated from A/V content in a different format. 
Third-party tools are available to convert from common A/V formats into the 

required format. One such tool that you can use is the MPEGEncoder available from
