sda 5273-3c delta specification semiconductor group 7 1999-01-27 1 delta specification 1.1 general information the sda 5273-3c 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 ? sda 5273 is also valid for compacttext sda 5273-3c except for the differences which are described in chapter 1.2 differences to the megatext? volume 1 documentation on page 10 . 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 5273-3c . 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 5273-3c 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 5273-3c 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 controls 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
sda 5273-3c delta specification semiconductor group 8 1999-01-27 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. 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 . table 1 display page high list pages basic top table flof links 1 - 4 additional information table pages next block page next group page flof index link last seen page next pages of btt last seen page next pages of page trace or next pages in binary order low

sda 5273-3c delta specification semiconductor group 51 1999-01-27 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: these bits define the number of frames which have to be pass without text reception. 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 infor- mation is transmitted in line 16, this data will never be recog- nized 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 16 d anymore because of possible teletext transmission in this line. setup parameter nu_te_fr_(7:0) bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 00110010 setup parameter nu_valid_head(7:0) bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 00000101
sda 5273-3c delta specification semiconductor group 52 1999-01-27 this function needs the setup parameter vps_wait(7:0) to define the wait time and can be activated by the setup parameter bit ena_line16/23. both parameters must be set before sending the command reset_acq . 1.10 signal quality status bits the compacttext provides some signal quality bits which can be read any time from the internal memory. these bits will be updated by the internal firmware several times per field. acq_en: acquisition sync signal quality reference. 1: hpll is locked very excellent. switching on the acquisition by the pu or external controller is useful. 0: hpll lock condition is bad. switching on the acquisition by the pu or external controller is not recommended. coi: coincidence indicator. 1: hpll phase difference is less then 4% of line period. line period does not need to be a tv line standard. 0: hpll is not locked. pull in range is 7% of 15625 hz line frequency. sync_err(3:0): horizontal sync distortion measurement. the measurement is done by counting the ripple during h-sync pulse. very good signal 1 < sync_err 15 bad signal setup parameter vps_wait(7:0) bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 01101111 signal quality status bits_0 / block 0 / byte 0 / row 3 / col 34 bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 s525 v_fine sync_ err_3 sync_ err_2 sync_ err_1 sync_ err_0 coi acq_en signal quality status bits_1 / block 0 / byte 1 / row 3 / col 34 bit15 bit14 bit13 bit12 bit11 bit10 bit9 bit8 nu nu nu nu nu nu nu pdf_ok
