 Encoding Closed Caption Data

 

The Z3-SBE264-10-RPS supports extraction of closed caption data from composite or SDI input. This 
automatically occurs any time composite or SDI input with closed caption data included is used. 
Encoding and subsequently extracting closed caption data from composite is shown below:

 

 

 

(1)

 

Connect a composite input with closed caption data to the Z3-SBE264-10-RPS using the supplied 

composite adapter cable: 

 

 
 
 
 
 
 
 
 
 
 
 
 
 

(2)

 

Configure the Encoder to use Composite input (see previous section for details on creating second 

channel for Composite).

 

 

(3)

 

Open VLC.  Select “Open Network Stream.”  If the settings are those as pictured in Figure 36, use the 

address “udp://@192.168.0.6:5004”.

 

(4)

 

In VLC, select “Subtitle – Sub Track – Closed Caption 1”. This configures VLC to use the extracted 

Figure 35  Connections for Closed Caption Extraction
