Service manual SC-150

1-3 ATSS sorting method

The TV set sweeps all the TV bands from beginning of VHF to end of UHF. The TV controlling software for each program checks if a VPS CNI code is transmitted ( this system exists for German, Swiss and Austrian transmissions). If no VPS CNI code is found, then the system check if a CNI code is transmitted as part of the teletext transmission ( Packet 8/30 format 1 ). If such a code ( VPS or teletext ) is found and if this code is in the ATSS list, the program is automatically named.

If the transmission does not have VPS CNI, and no teletext service is availab le, then there is no possibility of the program being automatically named.

The programs found are then sorted in 4 groups :

Group I : It contains all the pro grams from the selected country and named by the TV controlling software. Within this group the sorting order is fixed by the ATSS list.

Group II : It contains all the pro grams with a strong signal strength which are not listed in group I.

Group III : It contains all the pro grams with a weak signal strength which are not listed in group I.

Group IV : If two or more programs with the same code are found, only the strongest ( or if they have the same level the one with the lowest frequency) is listed in group I, II or III. The others are listed in group IV.
