bktr(4)

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) con-
     troller 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
     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
