Video Processing
U16500 S-Video switching processes the selected S-Video input and sends the separate Y/C components to the FPIP U18100.
12 U16501 Composite Video switching processes the selected source and sends the composite video to the FPIP (U18100).
13 U18100 The FPIP process NTSC signals and PIP signals and sends the Y/C components to U22300.
14
U22300 NTSC Decoder converts the Y/C signal from U18100 to YUV (1H). U22300 also processes the 2H YPrPb signal and outputs RGB to the CRT(s).
15 U22402 YUV and YPrPb switching IC selects between component in and YUV converted NTSC and routes the signals to U22401 and U32201.
16 U32201 The Matrix switch takes 1H YUV and Gemstar OSD and switches the output for up-conversion
17 U32251 The digital decoder converts analog NTSC video to digitized component video. The CCIR656 data is sent to the de-interlacer.
18 U32301 De-interlacer takes the digital data and reformats it to progressive scan. This process also provides the maximum image quality for a given image sequence.
19 U32501 The Digital to Analog converter takes the digital signal from U32301 and converts it back to analog YPrPb and sends it to U38200.
20 U38200 RGB/YPrPb switches between the High resolution input and the converted signal from the SRC module. These signals are then sent to U22401.
21 U22401 The 2H Select switch selects between 2H (only) signals from U22402 and U38200 and sends the signals to U22300 Video Processor.
