NAME

     bktr — Brooktree Bt848/849/878/879 and Pinnacle PCTV video capture driver

SYNOPSIS

     device bktr

     device iicbus
     device iicbb
     device smbus

DESCRIPTION

     The bktr driver provides support for PCI video capture and VBI capture on low cost, high
     performance boards.  The driver is based on the Matrox Meteor driver and uses the same API.
     The bktr driver should support most video cards based on the Brooktree Bt848/849/878/879
     Video Capture Chip.  Also supported are most Pinnacle PCTV video cards.  Furthermore, the
     driver supports FM Radio if the tuner supports it.

     The driver currently supports the following features:

           PCI to PCI dma transfer
           clipping
           yuv
           rgb16
           rgb24
           rgb32

     On the supported cards, tuners and other components are interconnected with an I2C bus.  The
     Brooktree848 chips act as a master device on the bus to control them.  Therefore, iicbus(4),
     iicbb(4) and smbus(4) controller declarations are mandatory to activate bktr support.

     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.

     options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
     options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_NTSC
     One of these options can be used to set the default video format for the driver.  This fixed
     random hangs and lockups with the VideoLogic Captivator PCI card.

     The following sysctls may be used to further configure the driver:

     sysctl hw.bt848.card=nnnn This can be used to override the card make which was detected at
     boot time.  ‘nnnn’ is set to an integer from 1 to 23 taken from the following table:

     MIRO                            1
     HAUPPAUGE                       2
