SDA 5273-2C
Delta Specification 1 1.1 Delta Specification General Information
The SDA 5273-2C is a powerful one-chip videotext decoder with all the display features of his "big brother" SDA 5273 but with a very simple command interface for reduced external software. The whole documentation of the MEGATEXT(R) SDA 5273 is also valid for COMPACTTEXT SDA 5273-2C except for the differences which are described in chapter 1.2 "Differences to the MEGATEXT(R) Volume 1 Documentation" on page 9. After power-on of the system, the setup parameters for CTX must be initialized by the external controller. These setup parameters are read every time when necessary by the SDA 5273-2C. The complete page management is done on chip. TOP and FLOF detection is done automatically, as well as the acquisition of packet 8/30/1, 8/30/2 or VPS and WSS data. The initial teletext page is taken from packet 8/30 (if present) or from the setup parameter or from the 5th FLOF link (if present). The user has several choices to enter a page request. One way is entering a page number for a new display page with the "DIGIT" commands. It is also possible to enter a page request by a "page catching" or with the colour keys RED, GREEN, YELLOW, and CYAN. These keys have different meanings depending on the current request mode (simple, TOP, FLOF). In all cases only the new display page has to be entered and all following page requests are automatically done by the firmware depending on the current mode. Some additional status information is also available (i.e. TOP, FLOF, page found...) for generating individual messages like "page xxx not broadcasted" by the external controller (return parameter). For page acquisition a maximum of 10 pages (+ 2 chapters for x/26) is available. After reset, the SDA 5273-2C is in the "simple mode", that means the initial page (page 100) and the following 9 pages are requested. The processor will start with the picture mode. SDA 5273-2C automatically changes to the page trace mode as soon as the page trace is stable. The user has the possibility to block up to 4 of the 10 available pages (with the list page command) for so-called favourite or list pages. These pages are favourite page numbers of the user, programmed for each program individually, and stored for example in the NVM of the TV. These pages can not be removed by the automatic TOP or FLOF requests. In the list mode, a special menu in row 24 can be generated for easy page selection by use of the remote control`s colour keys. In TOP mode, the BTT and a given number of AITs are immediately requested. Then the memory is filled with the next block page, group page and so on (see below). A standard TOP title is also written to row 24 of the display memory. TOP mode is only switched on automatically if more than 10 pages are marked in the BTT.

SDA 5273-2C
Delta Specification In FLOF mode, the four link pages and the index page of the display chapter given by x/27/0000 are requested. No page request will be made twice. For storing packets x/26, two chapters are reserved. With the help of these two chapters, it is possible to make visible all characters with diacritical marks and from G2 and G3 characterset. Packets x/27/0000 are compressed and stored in Row 25 of each Chapter. The reception of Packets 8/30/0/1 and 8/30/2/3 is always enabled. 1.1.1 Page Request Priority Table
Pages are requested in the order of their priority until the memory space is exhausted. The priority of all pages is fixed in table 1.

1.2 1.2.1
The firmware initializes the display mask register OSMR, ISMR0, ISMR1,BOXMR0 and BOXMR1 to 00 00 00 00 00 00H. Therefore, the display generator uses all 6 attribute bytes of the character display words in block 2 and 3. To prevent the interpretation of byte position 5 attributes of a character display word, the user software has to initialize the above mentioned display mask registers to FF 00 00 00 00 00H and the related control registers OSDW, ISDW0, ISDW1, BOXDW0 and BOXDW1 must be 00 xx xx xx xx xxH (xx means customer-specific values that depend on the application). An example for COMPACTTEXT initialization is given in this document. Refer to chapter 2.1 "Example for COMPACTTEXT Initialization" on page 54. 1.2.2 Firmware Overview

This chapter contains a list of commands from the COMPACTTEXT command interface MCI in alphabetical order. The documentation for each command contains a statement about the command's purpose, a description of its input parameters with used parameter registers, and a description of its return values with used parameter registers. The documentation contains additional important comments for some functions that a designer needs in order to properly use the command. 1.3.1 How to Use an MCI Command
Set all MCI input parameters as described. Set the CMD RUN bit in MCI input parameter register "MCI3_1" bit position MCI3_1_0 to activate MCI handshake. Transmit the MCI command to subaddress MCI COMMAND (see MEGATEXT(R) documentation volume 1, chapter "M3L-Bus Registers Programmers Reference"). As long as the MCI command is in execution, the CMD RUN bit will be in the 1 condition. Use a polling technique to detect whether the CMD RUN bit has changed into the 0 condition. If the CMD RUN bit is in the 0 condition, the MCI is ready to receive a new command. Always evaluate the return parameters, especially the error code. 1.3.2 Command Handshake
An MCI command can be given only if the previous command is finished. The CMD RUN bit shows the command status. As long as it is in the 1 condition, a command is in execution. The external controller must check this bit before giving a new command. The user is responsible for setting the CMD RUN bit before giving the MCI command. The CMD RUN bit is reset to 0 by the internal firmware after the command is executed. MCI3_1 / COMMAND STATUS
0 0 0 0 0 0 0 CMD_RUN
CMD_RUN:
MCI command running flag 1: MCI command is in execution. 0: MCI command is finished.

Delta Specification 1.7.5 Format of TOP Title
As soon as the TOP mode is recognized by the SDA 5273-2C, the firmware will create a TOP title in row 24 of the current display chapter. The TOP title will be updated each time after the BTT is received. Pages which are not included in the AIT will be represented by their digit page number. Table 21 Column Position Description Example Colour 1.7.6 0-4 Previous Page red Format of Stored BTT 5-9 Next Page + green 10 - 24 Next Block/Group News yellow 25 - 39 Next Block 111 cyan
The BTT is hamming checked and compressed before storing so that it is only necessary to store 400 Bytes. Because the AITs are automatically requested, there is no need to store the page linking table and the basic TOP table list. The BTT is stored at a fixed position starting at block 1 / byte 5 / row 15/ col 5. Two pages are stored in one byte. The code of the lower page number is stored in the higher nibble, the next page in the least significant nibble. So in one row the codes of 80 pages are stored. Because of less storage capability for the possible AITs in parallel mode, TOP is not supported in parallel magazine mode. Storage of 2 BTT Codes in One Byte

Delta Specification 1.8 Wide Screen Signaling (WSS), Video Program System (VPS)
The SDA 5273-2C has an integrated single data line module for real-time WSS and VPS processing. If this module is enabled, the internal PU takes over the control of the M3l-Bus Register 98 SINGLE_DATA_LINE. The single data line module switches automatically between line 16 (VPS) and line 23 (WSS) in one field. The WSS data are error checked and written to a buffer in the internal memory. Their actual values can be read at any time. The received data are biphase decoded and only written if the whole WSS line is received without any errors. Clock-run-in and framing-code are not stored. The threshold when the data should be indicated as valid can be controlled by the setup parameter WSS_CNT(7:0). This input parameter sets the threshold how often the WSS data have to be received without any errors in sequence before the data will be stored and the REC_WSS bit will be set in the return parameters. To enable the WSS/VPS module set the bit ENA_LINE16/23 in the setup parameters before giving the command RESET_ACQ. Initialize the M3l-Register EXTRA FRAMINGCODE WINDOW to B4H. 1.8.1 Wide Screen Signaling (WSS)

Delta Specification 1.9 Teletext Identification
The COMPACTTEXT provides an internal module to recognize whether the current TV channel transmits teletext or not. This module delivers a bit (TEXT_INT) in the return parameters which indicates this information. To activate this function, the following input parameters must be set: Setup Parameter NU_TE_FR_(7:0)
bit7 0 bit6 0 bit5 1 bit4 1 bit3 0 bit2 0 bit1 1 bit0 0
These bits define the number of frames which have to be pass without text reception. Setup Parameter NU_VALID_HEAD(7:0)
bit7 0 bit6 0 bit5 0 bit4 0 bit3 0 bit2 1 bit1 0 bit0 1
Number of valid headers.This parameter is used together with NU_TE_FR_(7:0) to define a criterion for the text identification modul. With the NU_TE_FR_(7:0) you define the number of frames with text information and with NU_VALID_HEAD(7:0) you define the number of headers within these frames. All hamming coded bytes of the detected headers must be free of errors before a header will be interpreted as valid. This monitoring of the text identification is active all the time. 1.9.1 Teletext Identification in Line 16
The COMPACTTEXT hardware has two paths for data reception. One path is for the teletext reception and the other one for the reception of the single data line services. For both data paths a separate framingcode is defined. The switch between the two branches will be done via the M3l-Bus register 98 SINGLE_DATA_LINE. Example: The M3l-Bus register 98 is set to line 16. An incoming line 16 will only be processed in the single data line path, not in the teletext path. Be careful that with this setting, if teletext information is transmitted in line 16, this data will never be recognized by the text decoder.
To overcome this situation an extra function is implemented in COMPACTTEXT to check first if this channel provides VPS information or not. With a channel change (command RESET_ACQ must be given), the single data line will be set to line 16 for a given time span. After this time, a decision will be made depending on the return parameter bit LINE16_VPS. If this bit is set to 1 the single data line will further be used to receive VPS info in line 16. If this bit is still 0 the single data line will not be loaded with the value 16d anymore because of possible teletext transmission in this line.
