GENERAL DESCRIPTION
The SAA5191 is a bipolar integrated circuit that extracts
teletext data from the video signal (CVBS), regenerates
the teletext clock (TTC) and synchronizes the text display
to the television signals (VCS). This device operates in
conjunction with the Digital Video Teletext (back-end)
Decoder (DVTB - SAA9042A) or any other compatible
device.
