Hauppauge WinTV-HVR-950Q

A hybrid ATSC USB 2.0 device by Hauppauge.

The digital side of the device is supported under Linux since kernel 2.6.26. Analog support was merged into the mainline v4l-dvb tree on March 18, 2009.

Note: This device, the HVR-950Q, is significantly different from the older HVR-950 model, so please be sure to differentiate between the two. For information on the older model, see the WinTV-HVR-950 article.

Making it Work

Firmware

In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000.

 wget http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip
 wget http://www.steventoth.net/linux/xc5000/extract.sh
 sh extract.sh
 cp dvb-fe-xc5000-1.1.fw /lib/firmware

Note: Though the usual directory location in which the firmware file is placed is /lib/firmware, this may differ in the case of some distros; consult your distro's documentation for the appropriate location.

The firmware will be added lazily (on-demand) when you first use the driver.

Drivers

The xc5000 driver needed for this WinTV-HVR-950Q is already part of the latest Linux kernel (part of v4l-dvb drivers).

Analog support was merged into the mainline v4l-dvb tree on March 18, 2009.
