Amiga Frame Grabber Project

Schalte um auf deutsch

Features:

• digitizes single video full frames with 768x575 pixels true color
• with scart and cinch connectors for usage with any CVBS source
• works (theoretically) independent from the video system
• signal processing is performed by the Amiga

The hardware:

• a small board with 2.75"x6.3" (7x16cm²) connected to the parallel port
• analog to digital conversion with the TDA8708A at 16MHz -> data sheet as PDF
• video frame storage with two video frame DRAMs HM530281R with 324KByte each -> data sheet
• integrated power supply (software contolled)
• schematics and PCB layout available in Postscript format

The software:

• written in AmigaE (by Wouter van Oortmerssen)
• user interface in EasyGUI (by Wouter/Jason R. Hulance):
  
  
• preview adjusts automatically to Workbench-Screen's aspect
• many Options:
  
  
• currently supported video standards: PAL
• twodimensional adapive three line combfilter
• interrupt controlled parallel port routine
• stores raw data, screen und true color
• localized
• supports OCS to AGA, 68k
• runs on AmigaOS 2.0 and above
• successfully tested on:
  • Amiga4000LC040 KS39.106(WB3.0)AGA 2C16F1.7HD
  • Amiga500 KS37.175(WB2.1)OCS 0.5C2.3F0HD
