DViCO FusionHDTV7 Dual Express

FusionHDTV7 Dual Express showing component labels (Click for High Resolution Version)

An ATSC PCIe card from DViCO.

It is supported under Linux since kernel 2.6.27. (Note: Analog support is not implemented yet).

Overview/Features

Able to deliver two digital channels. Or one analogue channel and one digital channel. Has an onboard mpeg2 encoder. High definition resolution is 1920 x 1080i.

Components Used

• Conexant CX23885 PCIe bridge
• Xceive Dual XC5000ACQ tuner (analogue and digital)
• Samsung S5H1409 or S5H1411 demodulator ¹

Note 1: The first revision of this board uses the S5H1409 whereas the later revision uses a S5H1411. Note that the PCI subsystem ID is the same for both boards. [1]

Making it Work

Firmware

The driver requires the standard xc5000 firmware (dvb-fe-xc5000-1.1.fw), to obtain the firmware see How to Obtain Firmware for XC5000.

Drivers

As of 20 September 2008, the drivers for the DVB side only have been incorporated into the main v4l-dvb tree, these will eventually be included into the linux kernel.

Driver Test Results

• Successful tuning of QAM 256 & QAM 64 channels.

-- User cybernard reports: Using OpenSuSE 11.0 and 11.1 kernel 2.6.27.7-9 I placed the firmware in /lib/firmware, the same location as the ATI HDTV Wonder firmware. I tried to get thd HDTV over the air 8-VSB, I believe, but it doesn't tune. Signal strength is almost always 0 despite being hooked the same antenna as a ATI HDTV Wonder which works just fine. Mythtv see the card, but can't find any channels.

femon -a 0 reports only "S" under status and the ATI HDTV Wonder status says "SCVYL"

Sometimes, not often, signal strength is 007d compare to fcd0 for ATI. However, 007d is the signal strength that the windows driver reports, but id decimal form of 125. This could simply be a scaling issue and multipling it by 256 may or may not help, but would bring the signal strength up to usable values since 125 to 127 offer perfect reception within windows.

Further Development Material

Further development is required to get the Analog side of this card working.
