GENERAL DESCRIPTION
The SAA4700T is a bipolar integrated circuit designed for
use in dataline receivers and incorporates a dataline slicer
and decoder. The slicer extracts the dataline signal from
the video signal and regenerates the data clock. It also
provides signals for the decoder in order to decode the
binary data that is transmitted in line 16 of every first field
of the composite video signal (video programming signal
and video recording programming by Teletext, VPS and
VPT systems). The decoded information out of words 5
and 11 to 14 is accessed via the built-in I
2
C-bus interface.
This information then can be used for programming a
video cassette recorder in order to start and stop a
recording of a television program at the correct aligned
time, regardless of a delay or extension in the transmission
time of the required program.
