CP-520V Service Manual

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 25KV at max beam current.
The high voltage must not, under any circumstances, exceed 29KV.
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

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.
Servicing should not be attempted by anyone who is not thoroughly familiar with the precautions
necessary when working on high voltage equipment.
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.
If any Fuse in this TV receiver is blown, replace it with the FUSE specified in the Replacement
Parts List.
When replacing a high wattage resistor (metal oxide film resistor) in the circuit board, keep the
resistor 10 mm away from circuit board.
Keep wires away from high voltage or high temperature components.
This receiver must operate under AC 230 volts, 50 Hz. NEVER connect to a DC supply or any
other voltage 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.

4.1.4 FEATURES
Analogue Video Processing (all versions)

· Multi-standard vision IF circuit with alignment-free PLL demodulator

· Internal (switchable) time-constant for the IF-AGC circuit

· Switchable group delay correction and sound trap (with switchable centre frequency) for the
demodulated CVBS signal

· DVB/VSB IF circuit for preprocessing of digital TV signals.

· Video switch with 3 external CVBS inputs and a CVBS output. All CVBS inputs can be used as
Y-input for Y/C signals. However, only 2 Y/C sources can be selected because the circuit has 2
chroma inputs. It is possible to add an additional CVBS(Y)/C input (CVBS/YX and CX) when the
YUV interface and the RGB/YPRPB input are not needed.

· Automatic Y/C signal detector

· Adaptive digital (4H/2H) PAL/NTSC comb filter for optimum separation of the luminance and the
chrominance signal.

· Integrated luminance delay line with adjustable delay time

· Picture improvement features with peaking (with switchable centre frequency, depeaking,
variable positive/negative peak ratio, variable pre-/overshoot ratio and video dependent coring),
dynamic skin tone control, gamma control and blue- and black stretching. All features are
available for CVBS, Y/C and RGB/YPBPR signals.

· Switchable DC transfer ratio for the luminance signal

· Only one reference (24.576 MHz) crystal required for the TCG m-Controller, digital sound
processor, Teletext and the colour decoder

· Multi-standard colour decoder with automatic search system and various “forced mode”
possibilities

· Internal base-band delay line

· Indication of the Signal-to-Noise ratio of the incoming CVBS signal

· Linear RGB/YPBPR input with fast insertion.

· YUV interface. When this feature is not required some pins can be used as additional
RGB/YPBPR input. It is also possible to use these pins for additional CVBS (or Y/C) input
(CVBS/YX and CX).

· Tint control for external RGB/YPBPR signals

· Scan Velocity Modulation output. The SVM circuit is active for all the incoming CVBS, Y/C and
RGB/YPBPR signals. The SVM function can also be used during the display of teletext pages.

· RGB control circuit with ‘Continuous Cathode Calibration’, white point and black level off-set
adjustment so that the colour temperature of the dark and the light parts of the screen can be
chosen independently.

· Contrast reduction possibility during mixed-mode of OSD and Text signals

· Adjustable ‘wide blanking’ of the RGB outputs

· Horizontal synchronization with two control loops and alignment-free horizontal oscillator

· Vertical count-down circuit

· Vertical driver optimized for DC-coupled vertical output stages

· Horizontal and vertical geometry processing with horizontal parallelogram and bow correction
and horizontal and vertical zoom

· Low-power start-up of the horizontal drive circuit

Analogue video processing (stereo versions)

· The low-pass filtered ‘mixed down’ I signal is available via a single ended or balanced output
stage.

Analogue video processing (mono versions)

· The low-pass filtered ‘mixed down’ I signal is available via a single ended output stage

Digital Video Processing (some versions)

· Double Window mode applications. It is possible to display a video and a text window or 2 text

CP-520V Service Manual

21

windows in parallel.

· Linear and non-linear horizontal scaling of the video signal to be displayed.

Sound Demodulation (all versions)

· Separate SIF (Sound IF) input for single reference QSS (Quasi Split Sound) demodulation.

· AM demodulator without extra reference circuit

· The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched
to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such
that the external band-pass filters can be omitted. In the stereo versions of UOCIII the use of this
demodulator is optional for special applications. Normally the FM demodulators of the stereo
demodulator/decoder part are used (see below).

· The FM-PLL demodulator can be set to centre frequencies of 4.72/5.74 MHz so that a second
sound channel can be demodulated. In such an application it is necessary that an external
bandpass filter is inserted.

· The vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio
signals. With an external FM tuner also signals with an IF frequency of 10.7 MHz can be
demodulated.

· Switch to select between 2nd SIF from QSS demodulation or external FM (SSIF)

Audio Interfaces and switching (stereo versions with Audio DSP)

· Audio switch circuit with 4 stereo inputs, a stereo output for SCART/CINCH, 1 stereo output for
HEADPHONE. The headphone channel has an analogue volume control circuit for the L and R
channel. Finally 1 stereo SPEAKER output with digital controls.

· AVL (Automatic Volume Levelling) circuit for the headphone channel.

· Digital input crossbar switch for all digital signal sources and destinations

· Digital output crossbar for exchange of channel processing functionality

· Digital audio input interface (stereo I2S input interface)

5.2 FUNCTIONAL DESCRIPTION OF VIDEO PROCESSOR

5.2.1 Vision IF amplifier

The vision IF amplifier can demodulate signals with positive and megative modulation. The PLL
demodulator is completely alignment-free.

The VCO of the PLL circuit is internal and the grequency is fixed to the required value by using
the clock ftequency of the TCG u-Controller as a reference. The setting of the various
frequencies (e.g. 38, 38.9, 45.75 and 58.75MHz) can be made via the control bits IFA-IFC in
subaddress 2FH. Because of the internal VCO the IF circuit has a high immunity to EMC
interferences.

The output of the AFC detector can be read from output byte o4H and has a resolution of
7bit(25kHz per step). By means of this information a fast tuning algorithm can be designed.

The IC contains a group delay correction circuit which can be switched between the BG and a
uncompensated group delay response characteristic. This hasthe advantage that in multi­standard receivers no compromise has to be made for the choice of the SAW filter. This group
delay corection is realised for the demodulated CVBS output signal. The IC contains in addition a
sound trap circuit with a switchable centre frequency.

5.2.2 QSS sound circuit

The sound IF amplifier is similar to the vision IF amplifier and has an external AGC decoupling
capacitor.

ThesinglereferenceQSSmixerisrealisedbyamultiplier. In this multiplier the SIF signal is converted
to the intercarrier frequency by mixing it with the regenerated picture carrier from the VCO. The
mixer output signal is suppliedtotheoutputviaahigh-passfilterforattenuation of the residual video
signals. With this system a high performance hi-fi stereo sound processing can be achieved.

TheAMsounddemodulatorisrealisedbyamultiplier.The modulated sound IF signal is multiplied in
phase with the limited SIF signal. The demodulator output signal is supplied to the output via a
low-pass filter for attenuation of the carrier harmonics.

SwitchingbetweentheQSSoutputandAMoutputismade by means of the AM bit in subaddress 33H.

5.2.3 FM demodulator

TheFMdemodulatorisrealisedasnarrow-bandPLL with internal loop filter, which provides the
necessary selectivity without using an external band-pass filter. To obtain a good selectivity a
linear phase detector and a constant input signal amplitude are required. For this reason the
intercarrier signal is internally supplied to the demodulator via a gain controlled amplifier and
AGC circuit. To improve the selectivity an internal bandpass filter is connected in front of the PLL
circuit.

The nominal frequency of the demodulator is tuned to the required frequency (4.5/5.5/6.0/6.5
MHz) by means of a calibration circuit which uses the clock frequency of the TCG(1)-Controller
as a reference. It is also possible to frequencies of 4.72 and 5.74Mhz so that a second sound
channel can be demodulated. In the latter application an external bandpass filter has to be

CP-520V Service Manual

34

applied to obtain sufficient selectivity (the sound input can be activated by means of the setting of
CMB2-CMB0 bits in subaddress 4AH). The setting to the wanted frequency is realised by means
of the control bits FMA, FMB and FMC in the control bit 33H.

From the output status bytes it can be read whether the PL Lfrequency is inside or outside the
window and whether thePLL is in lock or not. With this information it is possible to make an
automatic search system for the incoming sound frequency. This can be realised by means of a
software loop which switches the demodulator to the various frequencies and then select the
frequency on which a lock condition has been found.

The amplitude deemphasis output signal changed with 6dB by means of the AGN bit. In this way
output signal differences between the 4.5 MHz standard (frequency deviation25 kHz) and the
other standards (frequency deviation50 kHz) can be compensated.

5.2.4 Audio input selector and volume control

5.2.4.1 STEREO AND AV STEREO VERSIONS

The audio input selector circuit has 4 external stereo inputs, a stereo output for SCART/CINCH
and stereo outputs for headphone and audio power amplifiers. The selection is made with the
bits SAS2/0, SO2/0 and HPO2/0. AV stereo versions without Audio DSP have no headphone
output. The input signal selection for the volumecontrolledaudiooutputsisrealisedbytheHPO2/0
bits.

The gain from an external audio input to each of the (non-controlled) analog output is 0 or
+6dB(controlled by the DSG bit). A supply voltage of 5V allows input and output amplitude of
1VRMS full scale, as required to comply with the SCART specification, the audio supply voltage
must be 8V. In that case the gain of the audio amplifier must be doubled. This can be realised
with the DSG bit in subaddress 32H.

The circuit contains an analogue stereo volume control circuit with a control range of about 70dB.
This volume control circuit is used for the headphone channel (stereo versions with Audio DSP)
or for the main channel (AV stereo versions without Audio DSP). The analogue control circuit
also contains an Automatic Volume Levelling(AVL) function. When this function is activated it
stabilises the audio output signal to a certainl evel so that big fluctuations of the output power are
prevented.

5.2.4.2 MONO VERSIONS

The audio input selector circuit has 4 inputs for mono signals. The selection is made with the
HPO2/0 bits.

The circuit contains an analogue volume control circuit with a control range of about 70dB and an
AVL circuit.

5.2.5 CVBS and Y/C input signal selection

5.2.5.1 ALL VERSIONS

CP-520V Service Manual

35

The Ics have 3 inputs for external CVBS signals. All CVBS inputs can be used as Y input for the
insertion of Y/C signals.However, the CVBS(Y)2 input has to be combined with the C3 input. It is
possible to add and extra CVBS(Y/C) input via the pins which are intended to be used for YUV
interface (or RGB/YPrPb input). The selection of this additional CVBS(Y/C) input is made via the
YC bit.
The function of the IFVO/SVO/CVBSI pin is determined by the SVO1/SVO0 bits. When used as
output a selection can be made between the IF video output signal or the selected CVBS signal
(monitor out). This pin can also be used as additional CVBS input. This signal is inserted in front
of the group delay / sound trap circuit. It is also possible to use the group delay and sound trap
circuit for the CVBS2 signal (via the CV2 bit).

For the CVBS(Y/C) inputs the circuit can detect whether a CVBS or Y/C signal is present on the
input. The result can be read from the status register (YCD bit in subaddress 03H) and this
information can be used to put the input switch in the right position (by means of the INA-IND bits
in subaddress 38H). The Y/C detector is only active for the CVBS(Y)3/C3, CVBS(Y)4/C4 and
CVBS(Y)x/Cx inputs. It is not active for the CVBS(Y)2/C3 input.

The video ident circuit can be connected to all video input signals. This ident circuit is
independent of the synchronisation and can be used to switch the synchronisation and can be
used to switch the presence of a video signal (via the VID bit). In this way a very stable OSD can
be realised. The result of the video ident circuit can be read from the output bit SID (subaddress

00).

5.2.6 Synchronisation circuit

The IC contains separator circuits for the horizontal and vertical sync pulses. To obtain an
accurate timing of the displayed picture the input signal of the sync separator is not derived from
the various CVBS/Y or RGB/YPrPb inputs but from the YOUT pin. For this reason the YOUT pin
must be capacitively coupled to the YSYNC pin. The delay between the various inputs and the
YOUT signal can have rather large differences (e.g. comb filter active or not). By choosing the
YOUT signal as input signal for the sync separator these delays have no effect on the picture
position. Only for RGB signals without sync on green the input of the sync separator has to be
connected to one of the CVBS inputs. This selection is made by means of the SYS bit.

The horizontal drive signal is obtained from an internal VCO which is running at a frequency of
25 MHz. This oscillator is stabilised to this frequency by using the clock signal coming from the
reference oscillator of the TCG -Controller.

To obtain a stable On-Screen-Display (OSD) under all conditions it is important that the first
control loop is switched off or set to low gain when no signal is available at the input. The input
signal condition is detected by the video identification circuit. The video identification circuit can
automatically switch first control loop to a low gain when no input signal is available. This mode is
obtained when the VID bit is set to “0”. When the VID bit is “1” the mode of the first control loop
can be switched by means of the FOA/FOB or POC bits.

For a good performance during normal TV reception (display of the front-end signal) various
connections are active between the vision IF amplifier and the synchronisation circuit (e.g. gating
pulses for the AGC detector and noise gating of the sync separator). These connections are not
allowed when external video signals are displayed. The switching of these connections can be
coupled to the input signal selection bits (INA-IND). This mode is obtained when the VDXEN bit
is “0”. Due to the input signal selector configuration it is possible that the internal CVBS signal is

CP-520V Service Manual

36

available on one of the other CVBS inputs.In this condition the connections between the vision IF
amplifier and the synchronisation circuit can be switched on and off by means of the VDX bit.
The VDXEN bit must be set to “1” for this mode.

The vertical synchronisation is realised by means of a divider circuit.

5.2.7 Horizontal and vertical drive

The horizontal drive is switched on and off via the soft start/stop procedure. The soft start
function is realised by means of variation of the TON of the horizontal drive pulses. During the
soft-stop period the horizontal output frequency is doubled resulting in a reduction of the EHT so
that the picture tube capacitance can easily be discharged. In addition the horizontal drive circuit
has a ‘low-power start-up’ function.

The vertical ramp generator needs an external resistor and capacitor. For the vertical drive a

differential output current is available. The outputs must be DC coupled to the vertical output
stage.

The IC has the following geometry control functions:

n Vertical amplitude
n Vertical slope
n S-correction
n Vertical shift
n Vertical zoom
n Vertical scroll
n Vertical linearity correction. When required the linearity setting for the upper and lower part

of the screen can have a different setting.

n Horizontal shift
n EW width
n EW parabola width
n EW upper and lower corner parabola correction
n EW trapezium correction
n Horizontal parallelogram and bow correction.

When the East-West geometry function is not required (e.g. for 90 picture tubes) the EW output
pin can be used for the connection of the AVL capacitor. This function is chosen by means of the
AVLE bit.

5.2.8 Chroma, luminance and feature processing

Someversionscontaina4H/2H(2D)adaptivePAL/NTSC comb filter. The comb filter is
automatically activated when standard CVBS signals are received.A signal is considered as
“standard signal” when a PAL or NTSC signal is identified and when the vertical divider is in the
modes ‘standard narrow window’ or ‘standard TV norm’.For non-standard signals and for
SECAM signals the comb filter is bypassed and the signal is filtered by means of bandpass and
trap filters.

The chroma band-pass and trap circuits (including the SECAM cloche filter) are realised by
means of internal filters and are tuned to the right frequency by comparing the tuning frequency
with the reference frequency of the colour decoder.

CP-520V Service Manual

37

The circuit contains the following picture improvement features:
n Peaking control circuit. The peaking function can be activated for all incoming CVBS, Y/C

and RGB/YPrPb signals. Various parameters of the peaking circuit can be adapted by means
of the I2C-bus. The main parameters are:

- Peaking centre frequency (via the PF1/PF0 bits in subaddress 19H).

- Ratio of positive and negative peaks (via the RPO1/RPO0 bits in subaddress 47H). The
peaks in the direction “white” are the positive peaks.

- Ratio of pre- and aftershoots (via the RPA1/RPA0 bits in subaddress 47H).

n Video dependent coring in the peaking circuit. The coring can be activated only in the low-

light parts of the screen. This effectively reduces noise while having maximum peaking in the
bright parts of the picture.

n Black stretch. This function corrects the black level for incoming signals which have a

difference between the black level and the blanking level. The amount of stretching (A-A in
Fig. 72) and the minimum required back ground to activate the stretching can be set by
means of the I2C-bus (BSD/AAS in subaddress 45H).

n Gamma control. When this function is active the transfer characteristic of the luminance

amplifier is made non-linear.Thecontrolcurvecanbeadaptedbymeans of I2C-bus settings (see
Fig. 74). It is possible to make the gamma control function dependent on the picture content
(Average Picture Level, APL). The effect is illustrated in Fig. 75. Previously this function was
mentioned under the name “white stretch function”.

n Blue-stretch. This circuit is intended to shift colour near ‘white’ with sufficient contrast values

towards more blue to obtain a brighter impression of the picture.

n Dynamic skin tone (flesh) control. This function is realised in the YUV domain by detecting

the colours near to the skin tone.

n Scan-Velocity modulation output. Also the SVM function can be activated for all incoming

CVBS, Y/C and RGB/YPrPb signals. The delay between the RGB output signals and the
SVM output signal can be adjusted (by means of the SVM2-SVM0 bits in subaddress 48H)
so that an optimum picture performance can be obtained. Furthermore a coring function can
be activated. It is possible to generate Scan Velocity Modulation drive signals during the
display of ‘full screen’ teletext (not in mixed mode). Another feature is that the SVM output
signal can be made dependent on the horizontal position on the screen (parabola on the
SVM output).

5.2.9 Colour decoder

The ICs decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder does not need
external reference crystals but has an internal clock generator which is stabilised to the required
frequency by using the clock signal from the reference oscillator of the TCG u -Controller.

Under bad-signal conditions (e.g. VCR-playback n feature mode), it may occur that the colour
killer is activated although the colour PLL is still in lock. When this killing action is not wanted it is
possible to overrule the colour killer by forcing the colour decoder to the required standard and to
activate the FCO-bit (Forced Colour On) in subaddress3CH. The sensitivity of the colour decoder
for PAL and NTSC can be increased by means of the setting of the CHSE1/CHSE0 bits in
subaddress 3CH.

The Automatic Colour Limiting (ACL) circuit (switchable via the ACL bit in subaddress 3BH)
prevents that oversaturation occurs when signals with a high chroma-to-burst ratio are received.
The ACL circuit is designed such that it only reduces the chroma signal and not the burst signal.
This has the advantage that the colour sensitivity is not affected by this function.

CP-520V Service Manual

38

The SECAM decoder contains an auto-calibrating PLL demodulator which has two references,
viz: the divided reference frequency (obtained from the-Controller) which is used to tune the PLL
to the desired free-running frequency and the bandgap reference to obtain the correct absolute
value of the output signal. The VCO of the PLL is calibrated during each vertical blanking period,
when the IC is in search or SECAM mode. The frequency offset of the B-Y demodulator can be
reduced by means of the SBO1/SBO0 bits in subaddress 3CH.

The base-band delay line is integrated. In devices without CVBS comb filter this delay line is also

active during NTSC to obtain a good suppression of cross colour effects. The demodulated
colour difference signals are internally supplied to the delay line. The baseband comb filter can
be switched off by means of the BPS bit (subaddress 3CH).

The subcarrier output is combined with a 3-level output switch (0 V, 2.1 V and 4.5 V). The output

level and the availability of the subcarrier signal is controlled by the CMB2-CMB0 bits.

5.2.10 RGB output circuit

In the RGB control circuit the signal is controlled on contrast, brightness and saturation. The IC
has a YUV interface so that additional picture improvement ICs can be applied. To compensate
signal delays in the external YUV path the clamp pulse in the control circuit can be shifted by
means of the CLD bit in subaddress 44H. When the YUV interface is not required some of the
pins can be used for the insertion of RGB/YPrPb signals or as additional CVBS(Y)/C input. When
the YUV interface is not used one of the pins (VOUT) is transferred to general purpose output
switch (SWO1). The IC has also a YUV interface to th edigita ldie. Via this loop digital features
like “double window” are added.

A tint control is available for the base-band U/V signals. For this reason this tint control can be
activated for all colour standards. The signals for OSD and text are internally supplied to the
control circuit. The output signal has an amplitude of about 1.2V black-to-white at nominal input
signals and nominal settings of the various controls.

To obtain an accurate biasing of the picture tube the ‘Continuous Cathode Calibration’ system
has been included in these ICs. The system is slightly adapted compared with the previous
circuits. In the new configuration the cut-off level of the picture tube is controlled with a
continuous loop whereas the correction of the amplitude of the output signals is realised by
means of a digital loop. As a consequence the current measurement can be controlled from the­Processor. The value of the “highcurrent”intheCCCloopcanbechosenviatheSLG0 and SLG1 bits
(subaddresses 42H and 46H). The gain control in the 3 RGB channels is realised by means of 7­bit DACs. The total gain control range is6 dB. The change in amplitude at the cathodes of the
picture tube for one LSB is about 1.1 Vp-p. The setting of the control DAC is determined by the
following registers:
n The white point setting of the R, G and B channel in subaddress 20H to 22H. This register

has a resolution of 6 bits and the control range in output signal amplitude is +/-3 dB.

n The cathode drive setting (CL3-CL0 in subaddress 42H). This setting is valid for all channels,

there solution is 4 bits and the control range is +/-3 dB.

n The gain setting of the R, G and B channel. During switch on this register is loaded with the

preset gain setting of subaddress 23H to 25H and when necessary it will be adapted by the
CCC control loop. These registers have a resolution of 7 bits. The control of the gain setting
is illustrated in table below.

CP-520V Service Manual

WPR(GB) ‘0’ B5 B4 B3 B2 B1 B0 Max 64

CCC-gain B6 B5 B4 B3 B2 B1 B0 Max 126
R(GB)-gain B6 B5 B4 B3 B2 B1 B0 Max 126

The setting of the gain registers of the 3 channels can be stored during switch off and can be
loaded again during switch-on so that the drive conditions are maintained.

When required the operation of the CCC system can be changed into a one-point black current
system. The switching between the 2 possibilities is realised by means of the EGL bit (EGL = 0)
in subaddress 42H. When used asone-point control loop the system will control the black level of
the RGB output signals to the ‘low’ reference current and not on the cut off point of the cathode.
In this way spreads in the picture tube characteristics will not be taken into account. In this
condition the settings of the “white point control registers”(subaddress 20H-22H) and the
“cathode drive level bits” (CL3 - CL0 in subaddress 42H) are added to the settings of the RGB
preset gain registers (subaddress 23H - 25H).

A black level off-set can be made with respect to the level which is generated by the black
current stabilization system. In this way different colour temperatures can be
obtainedforthebrightandthedarkpartofthepicture.The black level control is active on the Red and
the Green output signal. It is also possible to control the black level of the Blue and the Green
output signal (OFB bit = 1).

In the Vg2 adjustment mode (AVG=1) the black current stabilization system checks the output
level of the 3 channels and indicates whether the black level of the highest output is in a certain
window(WBC-bit) or below or above this window (HBC-bit). This indication can be read from the
status byte 01 and can be used for automatic adjustment of the Vg2 voltage during the
production of the TV receiver. During this test the vertical scan remains active so that the
indication of the 2 bits can be made visible on the TV screen.

The control circuit contains a beam current limiting circuit and a peak white limiting circuit. The
control is realised by means of a reduction of the contrast and brightness control settings. The
way of control (first contrast and then brightness or contrast and brightness in parallel) can be
chosen by means of the CBS bit (subaddress 44H). The peak white level is adjustable via the
I2C-bus.

To prevent that the peak white limiting circuit reacts on the high frequency content of the video
signal a low-passfilter is inserted in front of the peak detector. The circuit also contains a soft­clipper which prevents that the high frequency peaks in the output signal become too high. The
difference between the peak white limiting level and the soft clipping level is adjustable via the
I2C-bus in a few steps.

During switch-off of the TV receiver a fixed beam current is generated by the black current
control circuit. This current ensures that the picture tube capacitance is discharged. During the
switch-off period the vertical deflection can be placed in an overscan position so that the
discharge is not visible on the screen.

A wide blanking pulse can be activated in the RGB outputs by means of the HBL bit in
subaddress 43H. The timing of this blanking can be adjusted by means of the bits WBF/R bits in
subaddress 26H.

n FM overmodulation adaptation option to avoid clipping and distortion

5.3.1 Supported standards

The multistandard capability of the TV Sound Processor covers all terrestrial TV sound standards,
FM Radio and satellite FM.

The AM sound of L/L' standard is normally demodulated in the 1st sound IF. The resulting AF
signal has to been tered into the mono audio input of the TV Sound Processor. A second
possibility is to use the AMdemodulator in the DEMDEC part, however this may result in limited
performance.

Korea has a stereo sound system similar to Europe. It is supported by the TV Sound Processor.
Differences include deviation, modulation contents and identification. It is based on M standard.

Other features of the DEMDEC are:

n M/BTSC and N standards supported
n M/Japan (EIAJ) supported
n FM Radio stereo decoding
n Alignment-free, fully digital system
n For BTSC full dbx® performance
n SAP demodulation (without dbx®) simultaneously with stereo decoding, or mono plus SAP

with dbx®

n Line/pilot frequency selectable from 15.734 kHz and 15.625 kHz (or automatic detection /

auto search)

n High selectivity for pilot detection, high robustness against high-frequent audio components
n Pilot lock indicator
n SAP detector
n Separate noise detectors for stereo and SAP with adjustable threshold levels, hysteresis, and

automute function

An overview of the supported standards and sound systems and their key parameters is given in
the following tables.
The analog multi-channel sound systems (A2, A2+ and A2*) are sometimes also named 2CS (2
carrier systems).

5.4 FUNCTIONAL DESCRIPTION SOUND PROCESSOR

5.4.1 The UOC III TV Sound Concept

The UOCIII sound concept is implemented over the video processor and TCG-microcontroller.
Only relevant blocks, functions and signal flows for sound are given.

The tuner receives a RF signal and converts it to IF. Via appropriate SAW filters the SIF signal is
delivered to the QSS stage of the video processor and if channels according to standard L/L’ are
received also to the AM demodulator. The Quasi Split Sound demodulation generates the SSIF
or intercarrier signal. By the SSIF switch it is possible to choose between the internally derived

CP-520V Service Manual

43

intercarrier and an external second SIF(2NDSIFEXT), e.g. an intercarrier coming from a PIP
frontend. In other applications a 10.7MHz radio IF or satellite FM may be connected to this input.
The selected SSIF passes some anti alias filtering, is amplified in an AGC amplifier (SSIF AGC)
and is then converted from analogue to digital (SSIF ADC).

The audio signal out of the AM demodulator is connected to the analogue crossbar at the video
processor. All other inputs to this multiplexer/audio switch come from external, either from a PIP
frontend or SCART/CINCH(AUDINx) or the DAC output signals from the digital controller. The
audio AD converters are digitising the audio signals foreseen for further digital processing. One
stereo output (AUDOUTS) is available for connections to SCART/CINCH sockets.

The sound part on the digital controller consists of the demodulator/decoder(DEMDEC), a digital
input crossbar, the digital audio processing for the loudspeaker and DAC channels, the I2S
processing and interfacing, a digital output crossbar as well as the DA conversion.

An auxiliary audio control (volume control, AUX audio contr.) is available on the video processor.
Here it is applied to the headphone channel.

The part of the concept located in the digital controller will be described in the next chapters.

5.4.2 Functional Overview Of the digital controller sound part

The digital controller sound part consists of the SSIFADC, audio ADCs, DEMDEC HW, the sound
DSP core, audio DACs and I2S interface hardware as shown in fig below. The DEMDEC part of
the Sound DSP is used for the decoder and partly demodulator tasks. The AUDIO part provides
the sound features, from the level adjust unit up to the output crossbar. Audio DACs and I2S
hardware are converting the processed signals to analogue or digital audio.

The SSIF signal is applied to the SSIF ADC for conversion and is then fed to the DEMDEC
hardware processing mainly for demodulation but also some decoding tasks. Remaining

CP-520V Service Manual

44

decoding is done in the DEMDEC block of the Sound DSP. The DEMDEC processing will be
described in the next chapter.

The audio signals (AUD ADC IN) from the analogue crossbar pass the audio ADC and are fed
directly into the AUDIO part of the Sound DSP like the I2S signals, which is coming from I2S
processing hardware. After level adjust all signals from the DEMDEC and the I2S input are
available at the digital input crossbar. A special input is provided for the Noise/Silence Generator
needed for olby® Pro Logic® processing.

In standard TV applications the main channel signal(L,R) will be connected to the DAC2 for
reproduction at the speakers. With multichannel signals centre, surround or subwoofer channels
may be passed to the I2S outputs where external DACs may be applied. By this it is possible to
build Dolby Normal/Wide, Dolby Phantom Centre or Dolby 3 Stereo set-ups and also a VDS423
application.

5.4.3 Demodulator and decoder

INTRODUCTION

The TV sound processor provides an easy-to-use programming interface and built-in intelligence
for the demodulator and decoder part.

The sound demodulator is able to search for sound carriers and react to transmission mode
changes autonomously, without interaction of the micro controller software.

It is possible for a typical terrestrial TV application to setup the entire demodulator with
transmission of few control words.

The control interface still allows access to every detail, called demodulator expert mode, for
special applications such as satellite TV, more elaborated search algorithms etc.

The new TV Sound ProcessorDemodulator and
DecoderEasyProgramming(DDEP)interfaceprovides three possible approaches to setup the
demodulator and decoder parts:

n Auto Standard Detection (ASD)
n Static Standard Selection (SSS)
n Demodulator and Decoder Expert Mode (DDXM)

MIXER

The digitized 2nd SIF input signal is fed to the mixers, which mix one or both input sound carriers
down to zero IF. The mixer frequency is derived by the standard setting (Easy Programming) or
in the Demodulator and Decoder Expert Mode (DDXM) by a 24-bit control word for each carrier.
For NICAM demodulation, a feedback signal is added to the control word of the second carrier
mixer to establish a carrier-frequency loop.

FMANDAMDEMODULATION

An FM or AM input signal is fed via a band-limiting filter to a one of two demodulators that can be
used for either FM or AM demodulation. Four filters with different bandwidth are available. The

CP-520V Service Manual

45

output signal of the first demodulator can be used for further demodulation of multiplex signals
used in the BTSC, EIAJ and FM Radio standards.

FMIDENTIFICATION

The identification of the FM sound mode is performed by AM synchronous demodulation of the
pilot signal and narrow-band detection of the identification frequencies. The result is available via
the control bus interface. A selection can be made for three different modes that represent
different trade-offs between speed and reliability of identification. The mode is set by DDEP (for
FM two-carrier standards) or via expert mode. DDEP also performs automatic FM de-matrix
control in dependence on the identification.

FM/AMDECODING

A high-pass filter suppresses DC offsets from the FM/AM demodulators due to carrier frequency
offsets and supplies the monitor/peak function with DC values and an un-filtered signal, e.g. for
the purpose of carrier detection.

The audio bandwidth is approx. 15 kHz.
The de-emphasis function offers fixed settings for the supported standards (50s, 60s, 75s and

J17).
A matrix performs the de-matrixing of the A2 stereo, dual and mono signals to obtain the left (L)

and right (R) or language A and B signals.

FMPILOTCARRIERPRESENTDETECTOR

The TV Sound Processor provides FM A2 standard pilot carrier detection.

NICAMDEMODULATION

The NICAM signal is transmitted via DQPSK modulation at a bit rate of 728kBit/s. The NICAM
demodulator performs DQPSK demodulation and feeds the resulting bit stream and clock signal
to the NICAM decoder.

A timing loop controls the sample rate conversion circuitry to lock the sampling rate to the symbol
timing of the NICAM data.

NICAM DECODER

The NICAM decoder performs all decoding functions in accordance with theEBU NICAM 728
specification. After locking to the frame alignment word, the data is de scrambled by applying the
defined pseudo-random binary sequence; the NICAM decoder will then synchronize to the
periodic frame flag bitC0.

The status of the NICAM decoder can be read out from the NICAM status register by the user
(see the control-bus register description). The OSB bit indicates that the decoder has locked to
the NICAM data. The VDSP bit indicates that the decoder has locked to the NICAM data and that
the data is valid sound data. The C4 bit indicates that the sound conveyed by the FM mono
channel is identical to the sound conveyed by the NICAM channel. The error byte contains the

CP-520V Service Manual

46

number of sound sample errors, resulting from parity checking, that occurred in the past 128ms
period. The Bit Error Rate (BER) can be calculated using the following equation;

During NICAM mode a switchable J17 de-emphasis is supplied.

NICAM AUTO-MUTE

If the Auto Standard Detection (ASD) or the Static Standard Detection (SSS) feature is activated
the following auto mute function is in effect.

If NICAM B/G, I, D/K is received, the auto-mute is enabled and the signal quality becomes poor,
the built-in control automatically switches the output signal (DEC output) to FM channel 1. The
automatic switching depends on the NICAM bit error rate. The auto-mute function can be
disabled via the control bus.

This function is enabled by setting bit NIC_AMUTE to 0. Upper and lower error limits may be
defined by writing appropriate values to the corresponding control bits (NICLOERRLIM and
NICUPERRLIM). When the number of errors in a 128 ms period exceeds the upper error limit the
auto-mute function will switch the output sound from
NICAMtowhateversoundisonthefirstsoundcarrier(FM or AM). When the error count is smaller than
the lower error limit the NICAM sound is restored.

The auto-mute function can be disabled by setting bit NIC_AMUTE to 1. In this condition clicks
become audible when the error count increases; the user will hear a signal of degrading quality.

For NICAM L applications, it is recommended to demodulate AM sound in the first sound IF. The
demodulated AM is provided by the internal IF processor. For applications with external IF
processing the external demodulated AM signal can be connected to the SCART/Mono input of
the TV Sound Processor. By setting the EXTAM bit, the auto-mute function will switch to the
audio ADC input signal named EXTAM instead of switching to the first sound carrier. The ADC
source selector should be set to internal AM mono signal or to the external SCART/mono input,
where the AM sound signal should be connected.
