ADVANCE INFORMATION
Multistandard Teletext Processor for Level 1 and 2
Release Notes:
This paper describes only those functions and characteristics of the TPU 3041 which are
different to functions and characteristics of the TPU 3040.
For detailed information on common features please read the TPU 3040 data sheet.
The information given applies to TPU 3041, technical code 22.
Revision bars indicate significant changes to the previous version.
1. Introduction
The TPU3041 is a single-chip World System Teletext
(WST) decoder for applications in analog and digital TV
sets. It is designed for use in countries with Greek or
Cyrillic character sets. The Latin character set is still
supported including a wide range of national characters.
1.1. Technical Code Change from TC19 to TC22
TPU3041 TC22 is based on hardware and firmware of
TPU3040 TC20. The following table shows the improvements compared to TC18.

Display
Stop rolling time/header in parallel magazin mode
Different italics timing in 10MHz analog mode
Problem: Italics characters are displayed by shifting pixel in steps
of 1/4 clock periods. In 10 MHz analog mode, pixels are
shifted by 3/4 clock periods instead.
Row 26 character flicker without parity error
Row 26 overwriting pointers in row0
Problem:
Solution:
row 26 can address columns 32–39 in row 0
set bit “row 26 hold” in display mode
Row 26 not checking row 24 hold
Double height flicker after page clear
No support of Serbian language in character set 38
PRIO Interface
Jitter in MSYNC interface
Problem:
Solution:
display jitter of 1 pixel
enable skew delay
Display flicker during channel search
Memory Manager
Ghost rows overwriting memory
Problem:
Solution:

On channels with parallel magazine transmission, the
memory manager of TPU3040 can destroy ghost row
pointers. Received ghost rows are then written
randomly into memory.

TC22 also includes some firmware improvements
compared to TC20. Please check TPU3041 data sheet
for detailed description of the following commands:
Command 07
Command 18
Command 26
“Acquisition Mode”
“Read Reset Source”
“Display Page Request”
The two character sets which are exchanged by ESC
code can be defined with additional commands not
available in TPU3040. These commands (58 and 59)
can be used to define two character sets including eight
languages each. Table 2–1 shows the available languages in TPU3041.

TPU3041, Technical Code 19, did not include the user
font of TPU3040. The user font is used in some applications to generate OSD menus. To maintain compatibility
with existing TPU3040 applications and to guarantee
compatibilty to future versions, such as TPU3042 (Arabic/Hebrew), it was decided to change the font organization of TPU3041 from TC19 to TC22. This means that
the character mapping in the Cyrillic font is changed. External software generating OSD texts must use new
mapping tables.

In TC 22, command 60 was improved and now supports
all features of the full row attribute, such as double
height. Therefore it is not compatible to command 60 in
TC19. Please check TPU3041 data sheet for a more detailed description.

2. Functional Description
The original G2 font and the NTSC fonts of TPU3040
had to be removed from the character ROM.
The firmware was modified to support the additional
fonts “Greek” and “Cyrillic” using ESC code (1/11) to
switch between different character sets inside a teletext
page. The ESC code is only used during translation of
a teletext page from page memory into TTX display
bank. In the display bank the ESC code has no function.
20–255
not defined
Addressing of the fonts “Greek” and “Cyrillic” is achieved
by inserting level 2 parallel attributes into the display
bank. The existence of level 2 data in the TTX display
bank is a major difference between TPU3040 and
TPU3041 and made some additional commands necessary. Command 57 “Display Read Column” can be used
to read the full row attributes from the display bank.
Command 60 “Display Full Row” can be used to set the
full row attributes of the display bank without resetting
the level 2 bit.

3.4. Cyrillic Character Mapping
The Cyrillic font definition of TPU3041 does not match
the official specifications of the Cyrillic G0 character set
exactly as national options and packet 26 characters are
included.
The TPU3041 firmware uses tables to map the received
character code into the internal font definition. The same
tables should be used by external software for generation of Cyrillic OSD text.

ADVANCE INFORMATION
Note:
If not otherwise designated all parameters in the following table are specified as single bytes. As write parameter magazine numbers 8 and 0 have the same meaning, a read parameter the magazine number is a true 4-bit
number (e.g. magazine 8 = 00001000). For write parameters the values in parentheses indicate default values
after reset (in hex notation). For compatibility reasons every undefined bit in a write parameter should be set to
‘0’. Undefined bits in a read parameter should be treated as “don’t care”.
