realtime digitizer/framegrabber

• SVHS (Y/C) and FBAS (CVBS) inputs
• standard 23 pin male connector (compatible with the usual Amiga video connector) which is without the Prism24 add-on useless
• I2C-Bus connector
• supports both PAL and NTSC video standards
• supported resolutions: 720×570, 360×285, 240×192, 180×144, 120×96
• overscan is controllable by software
• 1 MB 30 ns Video Field RAM
• digitizer uses 4:1:1 video sampling, Prism24 uses 4:2:2
• digitized video can be read from the onboard video RAM as raw-data in double buffering mode
• the Xilinx chip performs realtime scaling of the video data and provides an interface for the Prism24 board
• revision 2 boards support AGA, the older ones not
• optional Denise adaptor for Amiga 2000
• VHI driver

optional Prism 24 () Digital Video Processor and Time Base Corrector module

• the Prism 24 activates the 23 pin video connector
• it can pass-through the digitized video or perform red, green, blue, colour, brightness and contrast adjustments to the output
• adds genlock capability to the FrameMachine, taking the Amiga’s video signal from the video slot
• the genlock features are:
  • FrameMachine mode
  • Amiga mode
  • Amiga over FrameMachine Key mode
  • FrameMachine over Amiga mode
  • “B0-Keying” mode (color B0 is transparent)
• with FrameMachine’s realtime video features, it can do PIP (picture in picture) of real video and computer video on one screen
• combined with a standard external Amiga Genlock, there is also the possibility to do PIP of two real video sources together with an Amiga overlay
• AGA compatible Prism 24s have jumpers which allow the selection of the machine type
