Page clearing in under 64 µs (1 TV line)
Separate storage of extension packets
(SAA5296/7, SAA5296/7A and SAA5496/7)
Inventory of transmitted Teletext pages stored in the
Transmitted Page Table (TPT) and Subtitle Page Table
(SPT) (SAA5296/7, SAA5296/7A and SAA5496/7)
Automatic detection of FASTEXT transmission
Real-time packet 26 engine for processing accented
(and other) characters
Comprehensive Teletext language coverage
Video signal quality detector.
1.4 Teletext Display
525-line and 625-line display
12 × 10 character matrix
Double height, width and size On-Screen Display (OSD)
Definable border colour
Enhanced display features including meshing and
shadowing
260 characters in mask programmed ROM
Automatic FRAME output control with manual override

palette of 64.
2 GENERAL DESCRIPTION
The SAA529x, SAA529xA and SAA549x family of
microcontrollers are a derivative of the Philips’
industry-standard 80C51 microcontroller and are intended
for use as the central control mechanism in a television
receiver. They provide control functions for the television
system and include an integrated teletext function.
The teletext hardware has the capability of decoding and
displaying both 525-line and 625-line World System
Teletext. The same display hardware is used both for
Teletext and On-Screen Display, which means that the
display features give greater flexibility to differentiate the
TV set.
The family offers both 1 page and 10 page Teletext
capability, in a range of ROM sizes. Increasing display
capability is offered from the SAA5290 to the SAA5497.
