DESCRIPTION
DESCRIPTION
The Integrated VIP and Teletext decoder (IVT1.1X) is
designed to decode 625-line based World System Teletext
transmissions. This single-chip teletext decoder hardware
is based on the SAA5244A with which it is completely
compatible.
Like the SAA5244A the device contains all the hardware
necessary to decode the teletext, but the SAA5254 also
contains extra hardware to process the extension packet
26 characters automatically, extending the markets to
which the TV chassis can be shipped and opening the
possibility of many more language options.
