Service manual

The tuner type is a PLL tuner and delivers the IF-signal, via audio and video SAW-
filters, to the HIP (High-end Input Processor). The HIP has the following functions:
• IF modulation.
• Video source - and record select.
• Color decoder.
• Synchronization.
Five video in/output connections (with audio connections) are available:
1. Front: interfaces CVBS
2. AV1: interfaces CVBS and YUV-input (1fH)
3. AV2: interfaces CVBS and Y/C (meant for VCR-connection)
4. AV4: interfaces YPbPr/RGB (HD) inputs (2fH).
5. Monitor out: interfaces CVBS out
The HIP delivers the signal to the PICNIC.
This IC takes care of:
• Analogue to Digital conversion and vice versa.
• 60 Hz interlaced to 60 Hz progressive scan conversion.
• Panorama mode.
• Noise reduction.
• Dynamic contrast.
For Digital Scan the PROZONIC is required, which can be connected to the PICNIC.
After the PICNIC the (now 100 Hz) YUV- and H/V-signals are fed to the HOP (High-end
Output Processor). This IC handles the video control and geometry part. The RGB-
