9.
'not sharp', a low/mid frequency peaking is used. There
is a coupling between the Auto Noise and the Auto
Sharpness algorithm: if noise is present in the video
content, then in general the sharpness will be made less
aggressive. Special care has to be taken to the
interaction of the LIMERIC and the vertical peaking of the
PICNIC: a too big amount of vertical peaking increases
the visibility of the 2DNR artefacts.
9.15.2 ‘Switch On’ Behaviour
Below find the start-up sequence:
1.
After the power is applied, the 'Standby supply' starts
oscillating, generating the +5V2 (and +3V3). A RESET is
generated and the OTC is awakened.
2.
Next step is the check whether the set needs to be in
‘Standby’ mode or not. Therefore, the NVM content is
read and the Standby-bit is checked. If the set is to stay
in Standby, there is no further action.
3.
If the set will switches 'on', first the degaussing will be
activated (12 seconds). Meanwhile the MSP is reset and
the Standby line is pulled low, leading to a full semi
standby mode (5 V and 8V switched on)
4.
The OTC waits until the +5V and the +8 V are fully
present. This is done by checking the AD-input of the
OTC. The +5V, +8V and I
2
C protection-algoritms are
activated.
5.
The HOP is instructed via the I
2
C-bus to start the drive.
Via the SUP-ENABLE signal, the main supply is
activated. The Line Deflection circuitry is supplied now
with the V
BAT
, and the EHT generation can start.
6.
During start-up of the deflection, I
C traffic must be
disabled for 250 ms to avoid data corruption. If flashes or
spikes are generated during EHT start-up, I
C data could
be disturbed or corrupted.
7.
After deflection is powered up completely, all the other
protection-algorithms are activated. The black current
stabilisation loop in the HOP is switched on. Some extra
checking is done to ensure that the loops are completely
stabilised. The OTC sets all the necessary parameters
for a correct sound and image and unblanks the picture.
