The main tuner is a PLL tuner and delivers the IF-signal, via
audio and video SAW-filters, to the main HIP (High-end Input
Processor). This HIP has the following functions:
•
IF demodulation.
•
Video source select and record select (for 1fH inputs).
•
Color decoder.
•
Synchronization.
The following video input/output connections (with audio
connections) are available:
•
Side: interfaces CVBS and Y/C.
•
AV1: interfaces CVBS (1fH).
•
AV2: interfaces CVBS and Y/C (meant for VCR or DVDR
connection).
•
AV3: interfaces CVBS.
•
AV4: interfaces YPbPr (2fH/3fH).
•
AV5: interfaces DVI (2fH/3fH).
The HIP delivers YUV and H/V-sync signals to the PICNIC (in
the Feature Box). This IC takes care of:
•
Analog to Digital conversion and vice versa.
•
2fH processing
•
Interlaced to progressive scan conversion.
•
Panorama mode.
•
Noise reduction.
•
Dynamic contrast.

After the PICNIC, the YUV-signals are fed to the FALCONIC for
"Natural Motion", followed by the Eagle for picture
enhancement ("FBX" in the block diagram). The processed
YUV signals (from Eagle or PICNIC) are, together with the
sync-signals from the PICNIC, then fed to the EBILD (Eagle
Based Intelligent LCD Driver). This programmed IC handles
the video control. The RGB-signals for CC/OSD (from the uP)
are also inserted via this IC. The video part delivers the RGB
signals to the LCD-panel.
The sound part is built around an MSP (Multi-channel Sound
Processor) for IF sound detection, sound control and source
selection. Amplification is done via a "class D" power amplifier.
The microprocessor, called OTC (OSD, TXT/CC and Control)
takes care of the analog CC/OSD in- and output processing.
The OTC, ROM, and RAM are supplied with 3.3 V. This voltage
is derived from the +12V via a DC/DC converter on the SSP.
The NVM (Non Volatile Memory) is used to store the settings;
the Flash-RAM contains the set software.
The power supply is based upon the one used in the FMxx
(Plasma Flat TV) chassis. It consists of a main supply (based
upon the down converter principle) and an auxiliary supply
(based upon the so-called LLC technology).
