auvitek -- Auvitek AU0828 video capture device driver SYNOPSIS
auvitek* at uhub? dtv* at dtvbus? video* at videobus? uaudio* at auvitek? audio* at uaudio? DESCRIPTION
The auvitek driver provides support for USB video capture devices based on the Auvitek AU0828 bridge. This hybrid analog/digital device requires a hi-speed USB host controller (such as ehci(4)) to function properly. For auvitek devices with analog audio capture interfaces, the uaudio(4) device driver provides access to the audio stream. Application soft- ware can find a video(4) device's audio(4) device by comparing the VIDIOC_QUERYCAP bus_info field with the audio device's AUDIO_GETDEV config field. The following cards are supported by the auvitek driver: Device Decoder Tuner Hauppauge WinTV-HVR-850 au8522(4) xc5k(4) Hauppauge WinTV-HVR-950Q au8522(4) xc5k(4) Cards with an XC5000 tuner require the firmware provided by the pkgsrc/sysutils/xc5k-firmware package to function properly.

dtviic, au8522, cx24227, lg3303, mt2131, nxt2k, zl10353, tvpll, xc3028, xc5k -- Inter IC (I2C) modules for DTV DESCRIPTION
The dtviic modules provide support for dtv(4) devices. The dtviic module group includes tuners, demodulators, and analog video decoders. The usual hardware structure consists of a host controller (connected for instance via usb(4) or pci(4)) that provides the data moving facil- ities (for the analog or digital video streams) and an iic(4) bus over which the other chips can be configured. For example, a typical dtv(4) setup would look like this: 1. Initialize transport stream (TS) port on the host controller. 2. Configure the demodulator that ``demodulates'' the information from an intermediate frequency (IF) that is provided to it by the associated tuner. This step typically includes setting the desired quadrature amplitude modulation (QAM) and bandwidth, among other things. 3. Configure the tuner. Typically this step includes at least setting the frequency. 4. Start TS transfer (using DMA transfers or USB high speed transfers). The supported demodulators include: au8522 Auvitek AU8522 ATSC/QAM64/QAM256 demodulator cx24227 Conexant CX24227 ATSC/QAM64/QAM256 demodulator lg3303 LG LGDT3303 ATSC/QAM64/QAM256 demodulator mt2131 MicroTune MT2131 ATSC demodulator nxt2k NxtWave Communications NXT2004 ATSC demodulator zl10353 Zarlink ZL10353 (Intel CE623x) COFDM/DVB-T demodulator The supported tuners are: tvpll Generic PLL-based tuners xc3028 XCeive XC3028 analog and digital tuner xc5k Xceive XC5000 analog and digital tuner FILES
