Header graphic - 4.7 K Bt848 Driver Project - 11.1 K

DESCRIPTION
Circuit2.gif - 0.7 K The Bt848 driver enables low cost high performance video for the FreeBSD, BSDI and Linux communities.

At $120 or less for Bt848 + tuner PCI card, it enables these communities to participate in the mass market for video.

A compelling use for this equipment will be video conferencing, not to mention the ability for college students to watch TV with their PCs when they are not doing their home work!

  • FXTV is our coolest tv viewer with support for software mpeg encoding and X-10 Mouse Remote support which allows to change the volume , tv channels, mute, freeze frame, etc...
  • Another TV client: DTV
  • There's an X11 remote control for tuning.
  • Supports the mbone tool vic . Here is the source for a module which allows vic to work with a Matrox Meteor or Bt848 based cards.
  • Sample mpeg movie generated with fxtv Knight.mpg
  • Sample command line video capture program. It periodically takes snapshots and saves the image in jpeg format. videocapture.c

  • With eeprom.c you can record the contents of the on-board EEProm.
  • Invoke as "eeprom 0 256" (Wincast/TV) or "eeprom 0 128" (STB TV/PCI).
  • With freq.c you can test/debug tuning.
  • With sign.c you can record the "signature"
  • of your card. This is useful for developing the card "auto-probe" code.
  • The (Almost Definitive ) Fourcc (YUV, YUV9, YUV12, etc..) Definition List.
  • A DOS toolkit from Philips for various I2C video/audio chips.
  • A nice list of channel frequencies for various areas around the world.
  • A GPL'd Linux Driver: Bttv
