Note: Updated Lurker's Guide available (but not this page!)

This page belongs to the old 1990s SGI Lurker's Guide. As of 2008, several of the Lurker's Guide pages have been updated for HDTV and for modern OS platforms like Windows and Mac. This particular page is not one of those, but you can see what new stuff is available here. Thanks!

Old (Pre-1994) SGI Video Boards

By Paul Spencer.

Here's the only place in the Lurker's Guide where you'll find information about these boards:

  • Video Framer
    A 6U VME-bus board that did single frame video-to-memory and memory-to-video operations. Supported virtually all video formats (analog composite, analog component, digital composite, digital component). (Only SGI video board to ever support digital composite!). Plugged into Personal Iris, and into Power Series (with a supplied 6U-to-9U VME adapter). All color and format conversions were handled in software; definately not a real-time product. Had it's own custom library and API (libvfr).
  • VideoLab
    A custom video I/O board for the Power Series VGX graphics. Did video-to-graphics and graphics-to-video operations; had no connection to system memory. Could not co-exist with VideoSplitter. Supported analog component I/O; a separate converter card for analog composite I/O was planned (and has connections on the breakout box) but was cancelled due to lack of market interest. Had it's own custom library and API (libvli). Internally the main VideoLab board was called VO1; the cancelled conversion board was called VH1.
  • VideoSplitter
    A custom video output board for the Power Series VGX graphics. Split the VGX graphics output into four screens of VGA, NTSC, or PAL resolution for multi-screen users (the main graphics display was disabled when VideoSplitter was in use). No library or API; enabled via the setmon(1G) command.
  • Live Video Digitizer
    A custom video input board for the Power Series GTX graphics. Did video-to-graphics operation only; supported analog inputs only. Custom API, which was part of Iris GL.
  • Broadcast Video Option (BVO)
    A daughter card for VGX graphics which allowed a composite analog output, plus allowed genlocking the graphics to a NTSC or PAL input. No API or library, configured via setmon(1G) and a supplied tool. Internally referred to as EV1 (which, confusingly, was also the internal name for Galileo).
  • Video Creator
    A product that converted the graphics output of a system to video. Existed in two versions: a VME-bus board, meant for use in Power Series machines with GTX and VGX graphics; and a version that lived in an external box, controlled via the SCSI bus. Provided analog outputs; could either scan convert down, or pass through a section, of the 1280 x 1024 60Hz graphics screen. Also had a single-frame output capability. Had it's own custom API and library (libvc).
