Video: High-end Input Processor (HIP, diagram B2)
In the N8 the TDA932xH input processor is used, which contains the following functions:
• IF demodulation.
• AFC signal generation, used to track drifting transmitters.
• Sound carrier re-generation (SIF).
• Sync acquisition, delivering HA and VA.
• Switching off IF-filtering.
The HIP has various inputs.
• Full matrix switch with:
§ 2 CVBS inputs
§ 2 Y/C (or additional CVBS) inputs
§ 1 CVBS front end input
• Two RGB and 1 YUV-input
Outputs: Three separate switchable outputs can be used:
• 1 YUV-output is fed to the PICNIC
• 2 CVBS outputs: One for CC-decoding (named CVBS-TXT) and the other for
output to MONITOR OUT to have WYSIWYR (What you see is what you record)
The input signals from the Front I/O are fed to the HIP and front detection is fed to the
Painter.
AV1 is a CVBS- and a YUV input (e.g. for DVD), while AV2 is meant for CVBS and Y/C
(SVHS). The third option is a MONITOR OUT-output.
