Encoding Closed Caption Data

The Z3-MVE-40 supports extraction of closed caption data from SDI input. This automatically occurs any
time SDI input with closed caption data included is used. To utilize this feature, complete the following:

(1)

Connect an SDI input with closed caption data to an SDI connector (see Figure 4 on page 11).

(2)

Start the encode.

(3)

Open VLC. Select “Open Network Stream.” If the settings are those as shown in Figure 10 on page
14, use the address “udp://@192.168.0.6:5004” (see Figure 16 on page 19).

(4)

In VLC, select “Subtitle – Sub Track – Closed Caption 1”. This configures VLC to use the extracted
closed caption data that the encoder has extracted and encoded. You should then see the subtitles
on the screen:

(1) Select “Subtitle – Sub Track – Closed Caption 1”
