DTP910 In-vision Decoder
Legal Recording
Many TV stations record all of their output, including burnt-in subtitles onto tapes. This normally requires one tape per language supported. The DTP910, however, can display two languages at once, one in the top half of the screen and the second at the bottom - saving on tapes, recorders and storage etc.
Passive Decoding
The DTP910 does not alter the original teletext. The outputs still contain the original data, and the analogue outputs carry the text pages and subtitles in their VBI. The DTP910 can therefore be used as a digital to analogue converter, or vice versa, which supports teletext. (Many digital to analogue video chipsets do not support teletext generation).

Display Systems
The DTP910 can be used in simple teletext based display systems, drastically reducing cost. Instead of purchasing televisions with in-built teletext decoders, one DTP910 can supply the text in-vision, removing the need for the decoders.
You will also be sure that all displays show the same page. It also frees you to use whatever display technology you like, be it PAL or SDI input.
