ATSS sorting method
The TV set sweeps all the TV bands from beginning of VHF to the end of UHF. The TV controlling software for each program
checks if a VPS CNI code is transmitted. If no VPS CNI code is found, the system checks if a CNI code is transmitted in the tele-
text lines ( 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.
The programs found are then sorted into 4 groups :
Group I : Contains all the programs 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 : Contains all the programs with a strong signal strength which are not listed in group I.
Group III : Contains all the programs 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.
Note : If two programs with the same name but a different code are found these two programs are listed in group I, II or III (e.g.
Regional program SW3 in Germany).
The sorting order within group II, III, and IV is based on the channel frequency. The program with the lowest frequency is allo-
cated the first rank in its group, and so forth until the last program of the group which has the highest frequency.
