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. SAA4700 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 I2C-bus interface. This information about SAA4700 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.
