BKTR(4)                FreeBSD Kernel Interfaces Manual                BKTR(4)

NAME
     brooktree -- 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.
     The driver also supports FM Radio if the tuner supports it.

     Specifically, the following cards are known to work:

           Hauppauge Wincast TV and WinTV/PCI
           STB TV PCI Television Tuner
           Miro PC TV
           Intel Smart Video Recorder III
           AverMedia cards
           Video Highway XTreme
           VideoLogic Captivator PCI

     The driver currently supports the following features:

           PCI to PCI dma transfer
           clipping
           yuv
           rgb16
           rgb24
           rgb32

     On these 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 Captiva-
     tor 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
     13 taken from the following table:

     MIRO                    1
     HAUPPAUGE               2
     STB                     3
     INTEL                   4
     IMS_TURBO               5
     AVER_MEDIA              6
     OSPREY                  7
     NEC_PK                  8
     IO_GV                   9
     FLYVIDEO                10
     ZOLTRIX                 11
     KISS                    12
     VIDEO_HIGHWAY_XTREME    13

     sysctl hw.bt848.tuner=nnnn This can be used to override the tuner make
     which was detected at boot time.  `nnnn' is set to an integer from 1 to
     13 taken from the following table:

     NO_TUNER                0
     TEMIC_NTSC              1
     TEMIC_PAL               2
     TEMIC_SECAM             3
     PHILIPS_NTSC            4
     PHILIPS_PAL             5
     PHILIPS_SECAM           6
     TEMIC_PALI              7
     PHILIPS_PALI            8
     PHILIPS_FR1236_NTSC     9       /* These have FM Radio support */
     PHILIPS_FR1216_PAL      10      /* These have FM Radio support */
     PHILIPS_FR1236_SECAM    11      /* These have FM Radio support */
     ALPS_TSCH5              12
     ALPS_TSBH1              13
