Teletext/OP-47: Reader Settings
This page of the Engineering Settings control window is concerned with the additional
information needed when working with OP-47 or PAL teletext.
The main information needed to detect and display PAL or OP-47 teletext is the number
the page on which the data is provided. In the case of PAL, the number of a line that
contains teletext data also needs to be specified. The above illustration shows the pages
used for teletext subtitles in the UK.
Note: This feature only applies to a limited range of SD video formats. You should also note
that the teletext detector simply looks for teletext packets in the specified location. It
doesn’t also check whether these packets contain any information.
