1-3 ATSS sorting method
The TV set sweeps all the TV bands from beginning of VHF to end of UHF. The TV controlling softw for each are
program checks if a VPS CNI code is transmitted ( this system e xists 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 softw Within this
are.
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.

Note : If two programs with the same name but a different code ar e found these two programs are listed in
group I, II or III ( e.g. Regional pro gram 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 : France
If France is selected, the TV controlling software swee ps all TV bands with France system selected firstly
( positi ve video modulation) and the second time with Europe system selected ( nega tive video modulation).
Special case : Switzerland
If Switzerland is selected the TV controlling software swee ps all TV bands with Europe system selected firstly
(ne ga tive video modulation) and the second time with France system selected ( positive video modulation).

Service Manual CP-099F
Special case : GB
Note for setellite 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 f ollowing 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 - NEW S , ...
example B ( if 2 BBC1 found ) : 1 - BBC1, 2 - BBC1, 3 - BBC2, 4 - IT V, 5 - -----, 6 - CH5, 7 -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
27.5 KV (21") at max beam current. The high voltage must not, under any circumstances.
exceed 31 KV (21"). 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 ( metal oxide film resistor) in the 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.

The Video Front End section takes in the analogue Composite Video 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 select and convert the analogue
CVBS signal into a digital form. This is done using 8 bit ADC sampling at 20.25 Mhz.
The digital data services transmitted in the VBI are selected and acquired separately form the video part. This is done
by the use of an adaptive data slicer. The following data types can be extracted : 625 line World System Teletext
(WST), VPS, WSS. The data is acquired and decoded by the teletext decoder (TPU), then stored in an SRAM lnterface.
