Configuring Your This section describes how to configure your system for successful end-to-end System processing of VBI data for each VBI scheme. For a detailed description of the front panel or remote commands used to implement the various VBI schemes,

refer to the appropriate command sections found in this manual.

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.

Tiernan CC Mode is for NTSC Format Only

Line 21 Becomes First Line of Active Video in Tiernan CC Mode

Line 261 is Last Line of Active Video in Tiernan CC Mode

Last Line of Normally Active Video Is Lost (Line 262)

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.

Operational Considerations

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

Hardware Requirements

■Encoders will properly process Tiernan closed captions with any of the following modules: TVIP-6021, TVIP-6025, or TVIP-6001.

■The TDR6 decoder processes VBI data in its standard configuration.

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.
