GENERAL DESCRIPTION
The SAA4700 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.
