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. If no VPS CNI
code is found, the system check if a CNI code is transmitted in the teletext 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 in 4 groups :
Group I: It 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 : It contains all the programs with a strong signal strength which are not listed in
group I.
Group III : It 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 allocated the first rank in its group, and so forth until the last
program of the group which has the highest frequency.

Special case : Country selection = Others
Special case : France
If France is selected the TV controlling software sweeps the whole TV bands firstly with France
system selected ( positive video modulation) and secondly with Europe system selected ( negative
video modulation).

Special case : Switzerland
If Switzerland is selected the TV controlling software sweeps the whole TV bands firstly with
Europe system selected (negative video modulation) and secondly with France system selected (
positive video modulation).
Special case : GB
Note for satellite receiver users : Before starting ATSS turn On your satellite receiver and tune “
SKY NEWS “.
If GB is selected the TV controlling software seeks for programs only in UHF ( C21 to C70). The
sorting order is :
1 - BBC1
2 - BBC2
3 - ITV
4 - CH4
5 - CH5
6 - NEWS
If two or more “ identical “programs ( same name but different code e.g. BBC1 and BBC1
Scotland ) are found the following programs in the list will be shifted up. (1 - BBC1, 2 - BBC1, 3
- BBC2, 4 - ITV, 5 - CH4, 6 - CH5, 7 - NEWS, ..)
If one of the program above is not found, the associated program number remains empty
(freq.=467.25 Mhz - Skip selected - no name - system=GB).
example A : 1 - BBC1, 2 - BBC2, 3 - ITV, 4 - -----, 5 - CH5, 6 - NEWS, ...

2 - Safety instruction
WARNING: Only competent service personnel may carry out work involving the testing or repair
of this equipment.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid
such hazards, the high voltage must not exceed the specified limit. The nominal value of the
high voltage of this receiver is 25-26 KV (20”-21”) or 26 KV (25” - 28”) at max beam
current. The high voltage must not, under any circumstances, exceed 27.5 KV (20”), 29KV
(21”), 29.5 KV (25") or 30 KV (28"). Each time a receiver requires servicing, the high
voltage should be checked. It is important to use an accurate and reliable high voltage meter.
2. The only source of X-RAY Radiation in this TV receiver is the picture tube. For continued
X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as
specified in the parts list.
SAFETY PRECAUTION
1. Potentials of high voltage are present when this receiver is operating. Operation of the
receiver outside the cabinet or with the back board removed involves a shock hazard from the
receiver.
1) Servicing should not be attempted by anyone who is not thoroughly familiar with the
precautions necessary when working on high voltage equipment.
2) Discharge the high potential of the picture tube before handling the tube. The picture tube
is highly evacuated and if broken, glass fragments will be violently expelled.
2. If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the
Replacement Parts List.
3. When replacing a high wattage resistor (oxide metal film resistor) in circuit board, keep the
resistor 10 mm away from circuit board.
4. Keep wires away from high voltage or high temperature components.
5. This receiver must operate under AC 230 volts, 5O Hz. NEVER connect to DC supply or
any other power or frequency.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this equipment have special safety-related characteristics.
These characteristics are often passed unnoticed by a visual inspection and the X-RAY
RADIATION protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Replacement parts which have these special
safety characteristics are identified in this manual and its supplements, electrical components
having such features are identified by designated symbol on the parts list. Before replacing any of
these components, read the parts list in this manual carefully. The use of substitutes replacement
parts which do not have the same safety characteristics as specified in the parts list may create X-
RAY Radiation.

Data Capture
The Data Capture section takes in the analogue Composite Vidéo and Blanking Signal
(CVBS), and from this extracts the required data, which is then decoded and stored in memory.
The extraction of the data is performed in the digital domain. The first stage is to convert the
analogue CVBS signal into a digital form. This is done using an ADC sampling at 12MHz.
The data and clock recovery is then performed by a Multi-Rate Video Input Processor
(MuIVIP). From the recovered data and clock the following data types are extracted WST
Teletext (625/525), Closed Caption, VPS, WSS. The extracted data is stored in either memory
(DRAM) via the Memory Interface or in SFR locations.
