VBI Data Transmission

SE4000 MPEG-2 Contribution Encoder

B-4

01-0934-401-B

To configure the encoder and decoder for ATSC closed captioning, follow these steps:

Encoder

1.

Ensure that Teletext is disabled. Issue the front panel command
Config>Service>VBI>Teletext>Enable=off or the remote TT ENABLE OFF command.

2.

Ensure that closed caption VBI data is included in the selected service video input signal.

3.

Enable the encoder for ATSC closed captions. Issue the front panel command
Config>Service>VBI>CC=On or the remote VE ATSC_CC ON command.

Decoder

4.

The set-top box should automatically detect and process ATSC closed captions.

B.1.3 Tiernan Proprietary Closed Captions (Tiernan CC)

Using Tiernan proprietary closed captions, two lines of VBI information are encoded per frame
(one per field) at the expense of losing two lines of active video (one per field). The encoded
picture is simply shifted up one line to include the last line of VBI and to exclude the last line of
active video in each field.

This proprietary mode is intended as a method to transmit line 21 EIA -608 closed captions in an
NTSC system without incurring more bandwidth requirements.

Tiernan proprietary closed captions are supported on a composite analog NTSC or component
digital (525) format video signal.

B.1.3.1 Operational Considerations

Ensure that VBI teletext is disabled when closed captions are enabled, as teletext overwrites all
other VBI data.

B.1.3.2 End-to-End Configuration

To configure the encoder and decoder for Tiernan proprietary closed captioning, follow these
steps:

Encoder

1.

Ensure that Teletext is disabled. Issue the front panel command
Config>Service>VBI>Teletext>Enable=off or the remote TT ENABLE Off command.

2.

Ensure that closed caption VBI data is included in the selected service video input signal.

3.

Enable the encoder for Tiernan closed captions. Issue the front panel command
Confi g>Service>VBI>Tiernan CC=On or the remote VE TCC ON command.
