DViCO FusionHDTV DVB-T Dual Express

DVico Fusion HDTV Dual Express PCB showing component labels

A hybrid DVB-T PCIe card from DViCO.

It is not supported under Linux. However, experimental support for the DVB-T side is available (see below for details). Note that there is also a completely unsupported Dual Express2 which appears to be a new revision and at least one supplier will supply this model without any information to identify it as a new revision.

Overview/Features

Able to deliver one analogue channel and one digital channel simultaneously or 2 digital channels. High definition resolution is 1920 x 1080. Features a power switch pass-through to allow it to turn the host system on automatically.

Components Used

• 2 x Xceive 3008ACQ (tuner IC)
• 2 x Intel WJCE6353 (digital demodulator)
• Conexant CX23885 (A/V Decoder / PCIe bridge)
• Pericom P15C.... (switch)
• PIC16F73 (external audio adc ? -- its used as such on the Fusion5 RT (note- the PIC16F73 is currently unsupported under Linux, so audio from external analog sources (a/v inputs) will not work); or maybe its being used for remote control (although that might be natively handled by the cx23885)?; or maybe its being used in conjunction with RTC duty ?)
• some Atmel eeproms
• some others (RF switch)...

The revision 4 card is also known to work with later kernels, 2.6.31.5 and probably others. Or, at least, it works for me (digital only).

Making it Work

Firmware

The driver requires the standard xc3028 firmware (xc3028-v27.fw), to obtain the firmware see instructions within the extract_xc3028.pl script (available within linux/arch/Documentation/video4linux/).

Drivers

In kernel drivers for the device only support digital functions of this card. No analog support available.

The patches applied to the v4l-dvb tree were derived by work originally completed by Chris Pascoe, the older version of these patches can be found here: http://www.itee.uq.edu.au/~chrisp/Linux-DVB/DVICO/

Sample kernel output

Note: If the card does not work ensure that 80 firmware images were loaded, if not see the firmware section above to get the correct version.

Remote Control Support

Remote does work. Have not had the time to map all keys.
