BKTR(4)		       FreeBSD Kernel Interfaces Manual		       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
     23	taken from the following table:

     MIRO			     1
     HAUPPAUGE			     2
     STB			     3

     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
     16	taken from the following table:

     NO_TUNER		     0
