1. INTRODUCTION

CTV5 is a Voltage Synthesis Tuning and control system for multi-standard TV receivers with

on-screen-display (OSD) for all relevent control functions. The system is based on I2C bus
controlled video processing IC STV223X/4X which also controls mono sound. The Nicam and
Zweiton demodulation is done using IC STV8216. It is also possible to do picture geometry
correction using IC STV9306.

The user interface is menu based control system with P+ ,P- ,V+ , V- , MENU, OK, ANALOG,
TV/DVD and TV/AV keys on Remote / local keyboard . Hence any menu related function could
be accessed using these six keys.

Teletext is done by the microcontroller on-chip teletext module.

4.8 I2C Lines :

Pins 19 (SDA) and 20 (SCL) of the MCU are the I2C Lines. The I2C bus is a 2 wire bidirectional
bus. The CTV5 has an on-chip bit level I2C interface . This means the hardware takes the bus
arbitration , the reception and transmission of data bits and generation of START and STOP
condition. The software must handle the bits (i.e save a received bit and prepare the bits which
must be transmitted. )
CTV5 supports 1K bytes EEPROM (ST24C08) used for storage of analog controls , Service
settings, Alarm Settings, tuning data for 99 pre-selected programmes and label for each of them.
The I2C address of the EEPROM is shown in the next chapter.
The Video processor STV223X/4X is controlled via I2C on address 8A hex.

It is available to enter SERVICE MENU when it is high for the voltage at pin 7 of MCU. It is
forbidden to enter the SERVICE MENU when the voltage level is l ow at pin 7 of MCU.

4.10 Default data control for EEPROM (Pin 14):

When pin 14 of ST92195 is connected to ground, all the default data can not be written to
EEPROM, even if it’s empty for all EEPROM. When pin 14 of ST92195 is connected to +5V,
all the default data can be wr itten into empty EEPROM .

5.2 Tuning :

This section describes the tuning algorithm , the corresponding OSD is described in the user
interface section.

5.2.1 Automatic tuning based on Voltage Synthesis Principle :

CTV5 provides an automatic tuning system in 3 different tuning bands . The search tuning
function requires a IDENT signal and AFC window status , which is read via I2C from
STV223X/4X. AFC status could be in one out of the following 5 states:
| F pll - Fo < -300 Khz
| -300KHz < F pll - Fo < -60 KHz
| -60 KHz < F pll - Fo < +60 KHz
| +60 KHz < F pll - Fo < +300 Khz
| +300 KHz <F pll - Fo

P

If the search is activated while the TV is tuned to a station (IDENT available ) , CTV5 will first
try to escape from it. The tuning voltage will be increased until ident fails. After this the search
for the new transmitter can start.
The tuning voltage is increased till the transmitter is found. When the tuning reaches the top of
the band , it will change to the next higher band. The band is tuned in the following order :
VHF-L VHF-H UHF
During the search CTV5 continuosly scans its IDENT and AFC status, read via I2C bus. Good
performance hence relies completely on the behaviour of these two signals.

5.2.2 Automatic Following :

Once the system is tuned via automatic tuning , the signal will stay locked by means of
automatic following (Using digital AFC ). This transmitter following will continue as long as the
transmitter identification signal stays present.
Once fine tune is activated the automatic following is disabl ed.
If Compilation option of FINE_TUNE_STATUS is selected ,the AFC status is stored with the
individual program. If the fine tune value of a particular program is not zero, the AFC following
for that program is disabled.

5.3 Sound System :

Presently the mono sound is received from STV223X/4X. This is fed as Mono I/P to STV8216.
In case the Nicam or Zweiton signal is not detected it switches to Mono input.

If in auto tuning “France” is selected , AM sound system will be selected . Also in Organize
menu if RF std. is selected as LL’ , AM sound system will be selected.

By pressing “NICAM” key on remote in normal mode , it is possible to change the language,
if the standard is NICAM DUAL or Zweiton DUAL.

APPENDIX A: IR REMOTE CONTROL

The M3004LAB1 transmitter IC is designed for infrared remote control systems. The data format
for the remote output is as follows

The pattern is pulse distance coded. These pulses are modulated. Modulated pulses allow receiv­ers with
narrow band preamplifiers for improved noise rejection.
In the modulated transmission the first bit is a constant reference time bit. This is used as a refer­ence time
for the decoding sequence. This is followed by a toggle bit. The toggle bits function is to indicate
to the decoder
that next instruction is to be considered as a new command.
The next 3 bits are for the Sub system address. These bits have been hardwired as 101 for CTV5.
The last 6 bits are command bits, the codes of which for different commands are listed in Section

4.7.

Controller Type ST92195
Crystal frequency of controller 4 MHz
IR Receiver type TFMS 5380 or Similar
IR Transmitter type M3004LAB1 or Similar
Crystal Frequency of IR Transmitter 455 KHz

For crystal of 455 KHz, t_osc = 2.2 us
Modulation period = Tm = 12 * t_osc = 26.4 us
Basic unit of pulse distance = To = 1152 * t_osc = 2.534 ms
Word distance = 55296 * t_osc = 121.65 ms
Logic “0” = 2To = 5ms (approx)
Logic “1” = 3To = 7.5 ms
Toggle bit = 5ms or 7.5 ms
Reference bit = 7.5 ms
