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. TPU 3040 Display 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. TC10 TC12 TC13 TC14 TC16 TC17 TC18 TC20 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. x x x x x 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 x x x x x x x x x x x Row 26 not checking row 24 hold Double height flicker after page clear No support of Serbian language in character set 38 PRIO Interface x x x x x x x x x x x x x x x 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: 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. 4 Mbit DRAM Solution: MICRONAS INTERMETALL 3 TPU 3041 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” ADVANCE INFORMATION 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. Table 2–1: Language table 1.2. Software Incompatibility between Technical Codes 19 and 22 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. 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.

Table 3–8: Cyrillic G0 mapping ADVANCE INFORMATION The TPU3041 firmware uses tables to map the received character code into the internal font definition.
