8.2.4. VBI
The ProView 2900 Series supports decoding and displaying Teletext Subtitling graphics
(according to DVB VBI standard EN 301 775, which specifies EBU Teletext subtitling data,
used for language translation).
Differently from DVB subtitling, Teletext Subtitling requires the decoder to be able to create
relevant language fonts. The ProView 2900 has the following Teletext Subtitling fonts
installed:
• Croatian
• Czech
• Danish
• Dutch
• English
• English Old
• Estonian
• Finnish
• French
• German
• Hungarian
• Italian
• Latvian
• Lithuanian
• Norwegian
• Portuguese
• Romanian
• Serbian
• Slovak
• Slovenian
• Spanish
• Swedish
Assigning a VBI to a Service through this menu allows adding Teletext Subtitles to the
Service (for this purpose, the selected VBI PID must contain Teletext Subtitling data).
When choosing Teletext Subtitling here, the operator must also enable TLTX Subtitle Mode.
For enabling TLTX Subtitle mode, see Section 9.4.
