DESCRIPTION
The bktr driver provides support for PCI video capture and VBI capture on
low cost, high performance boards. This 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:
Animation Technologies FlyVideo
Askey/Dynalink Magic TView
AverMedia cards
Hauppauge Wincast TV and WinTV/PCI
IMS TV Turbo
Intel Smart Video Recorder III
I/O DATA GV-BCTV2/PCI
KISS TV/FM PCI
Leadtek Winfast TV 2000
Miro PC TV
MMAC Osprey
NEC PK-UG-X017
STB TV PCI Television Tuner
Terratec TerraTVplus
Video Highway XTreme
VideoLogic Captivator PCI
Zoltrix TV
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 con-
trol them.
The following kernel configuration options are available:
option BKTR_ALLOC_PAGES=nnn
Specifies the number of contiguous pages to allocate when suc-
cessfully probed. The default number of pages allocated by the
kernel is 216. This means that there are (216*4096) bytes
available for use.
option BKTR_SYSTEM_DEFAULT="(BROOKTREE_PAL | BROOKTREE_NTSC)"
One of these options can be used to set the default video for-
mat for the driver. This fixed random hangs and lockups with
the VideoLogic Captivator PCI card.
option BKTR_OVERRIDE_CARD=nnn
Select a specific card (overrides autodetection). `nnn' is set
to one of the names listed and explained below.

The bktr driver first appeared in FreeBSD 2.2.
AUTHORS
The bktr driver is based on the work of Jim Lowe
<james@miller.cs.uwm.edu>,
Mark Tinguely <tinguely@plains.nodak.edu>,
Amancio Hasty <hasty@star-gate.com>,
Roger Hardiman <roger@FreeBSD.org> and a bunch of other people.
CAVEATS
On big-endian architectures it is not possible to program the card to
perform proper byte swapping in 24 bit modes, therefore only 16 and 32
bit modes are supported.
