Closed Caption Window
This window displays details of the closed captions or teletext subtitles detected in the
video being analysed.
The information shown comprises:
• The type of caption/subtitle – OP-47, PAL, Line 21, EIA-608 or EIA-708 (where
supported)
• The number of the service carrying the caption, together with any name that has
been associated with that service number
• Whatever caption data has been set
• Associated timing information (VITC, ATC, LTC, PC clock)
Where the system being used includes the 708 Decode option,
there is also the option (available through the Options menu) of
displaying the 708 windowing commands embedded in the video.
These commands are displayed in CEA-708-B standard format.
The source of the captions to be analysed may be set through the Closed Caption
source option in the Analyzer menu (see page 17).
Note: Some details of closed captions, for example their service names, are also recorded in
the Event Log (see page 104).
