14  Broadcast Time Delay
Rear Panel Connectors
The Broadcast Time Delay provides one video input with up to four audio channels, one delayed
video output with audio, and a second monitoring output which reflects input video and audio (E-
E), and can be used as a confidence-monitor.

VBI Lines Captured and Played
The Broadcast Time Delay records and passes through all VBI lines between 11 and 22 (inclusive,
field 1 and corresponding lines in field 2) in both NTSC and PAL. Following are examples of
recorded VBI data, along with their typical
1
line locations:
Line 11: PAL Video Index (PAL only – special processing enabled by default. See page 23.)
Line 12-22: Teletext (PAL – also line 11 if Video Index is disabled.)
Line 14 & 16: VITC
Line 19: Wink Data (Interactive TV)
Line 20, 22: AMOL (Nielson data)
Line 21: Closed captioning
Line 23 WSS (PAL)

With the exception of Video Index, the Time Delay can reproduce these signals on any VBI line.
