TechniSat Air2PC-ATSC-USB

There are actually two different ATSC USB boxes that were produced by TechniSat that bear the identical name Air2PC-ATSC-USB.

Both Air2PC models are supported under Linux. These are older devices that are no longer manufactured, and have been superseded by the presently offered AirStar-HD5000-USB model.

Origin of the Device's Name

The original "Air2PC ATSC USB" reference design was created by B2C2 and adopted by TechniSat for manufacturing. TechniSat never listed these Air2PC USB boxes on their own website's product pages (they only list the models' DVB-T counterpart, the AirStar USB). Rather, one finds information about these ATSC devices on the BBTI website (TechniSat's source for North American sales and distribution). Evidently, instead of marketing the devices using TechinSat's "*Stars" product lineup nomenclature, BBTI elected to use the original B2C2 naming scheme.

Air2PC-ATSC-USB (1st rev)

Instead of a traditional USB chipset, they utilize the B2C2 FlexCop IC for a bridge to the USB bus. (<-- don't think that part is right; there is very likely a USB bridge involved). Lacking an A/V decoder, these boxes are barren of analog inputs.

TechniSat/B2C2 Air2PC-ATSC-USB	USB1.1	Broadcom BCM3510	dvb-fe-bcm3510-01.fw	[1]

The original Air2PC model used the B2C2 FlexCop2 or FlexCop2b chipset with a Broadcom BCM3510 demodulator.

The following drivers are needed for this device:

 - bcm3510.ko
 - b2c2-flexcop.ko
 - b2c2-flexcop-usb.ko

Firmware

This device requires a firmware file (dvb-fe-bcm3510-01.fw) for the demodulator, which can be obtained from the LinuxTV downloads section. Once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros; consult your distro's documentation for the appropriate location).

Air2PC-ATSC-USB (2nd rev)

Instead of a traditional USB chipset, they utilize the B2C2 FlexCop IC for a bridge to the USB bus. (<-- don't think that part is right; there is very likely a USB bridge involved). Lacking an A/V decoder, these boxes are barren of analog inputs.

TechniSat/B2C2 Air2PC-ATSC-USB	USB1.1	NxtWave Nxt2002	dvb-fe-nxt2002.fw	[2]

This later Air2PC model variant also used the B2C2 FlexCop2 or FlexCop2b chipset, but was updated with a Samsung TBMV30111IN NIM that featured a NxtWave Nxt2002 demodulator.

The following drivers are needed for this device:

 - nxt2002.ko
 - b2c2-flexcop.ko
 - b2c2-flexcop-usb.ko

Firmware

This device requires a firmware file (dvb-fe-nxt2002.fw) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources:

# cd /[kernel source directory]/Documentation/dvb/
# perl get_dvb_firmware nxt2002

Once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros; consult your distro's documentation for the appropriate location).
