NAME
     bktr - brooktree video capture driver

SYNOPSIS
     device bktr0

DESCRIPTION
     The bktr driver provides support for PCI video capture on low cost, high
     performance boards.  The driver is heavily based on the Matrox Meteor
     driver.  The bktr driver should support most video cards based on the
     Brooktree Bt848 Video Capture Chip.

     Specifically, the following cards are known to work:
     Hauppage Wincast TV
     STB TV PCI Television Tuner
     Miro PC TV
     Intel Smart Video Recorder III

     The driver currently supports the following features:
          PCI to PCI dma transfer
          clipping
          yuv
          rgb16
          rgb24
          rgb32

     The following kernel parameters may be used to further configure the
     driver:

     options BROOKTREE_ALLOC_PAGES=xxx specifies the number of contiguous
     pages to allocate when successfully probed.  The default number of pages
     allocated by the kernel is 216.  This means that there are (216*4096)
     bytes available for use.
