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.
Overview/Features
The device supports NTSC, 8-VSB and QAM.
Components Used
- Xceive XC5000 (tuner and analog demodulator)
- Auvitek AU8522 (A/V decoder analog demodulator [not used], and digital demodulator)
- Auvitek AU0828 (USB bridge)
Identification
This descriptor is from a unit packaged as a "WinTV HVR 950Q, model 1176", which is shipped with the A/V cables and toy-sized antenna and a remote:

Making it Work
Firmware
In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000.
Note: The firmware is now bundled with Ubuntu 9.10 (Karmic), so users of that distro/version and newer do not need the following steps.
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.
Kernel 2.6.31 firmware issues
Kernel 2.6.31 requires dvb-fe-xc5000-1.6.114.fw firmware from here: [1] (to be saved as /lib/firmware/dvb-fe-xc5000-1.6.114.fw).
When running this kernel version, loading of the firmware takes very long, and prevents MythTV from working properly. To deal with this problem you can use xc5000's no_poweroff=1 module option, to prevent the device from sleeping (after which firmware has to be reloaded)
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.
Note: In the past, the HVR-950Q has had known issues with MythTV that prevent it from working. These should be fixed with the latest version. They were worked by the 950q maintainer (Devin Heitmueller). For more details, take a look at the KernelLabs blog for status updates: KernelLabs Blog
Sample Kernel Output
After you plug-in the device on a USB 2.0 port (it won't work with a USB 1.1) and use the driver for the first time (eg, by scanning channels), you may see something like this on dmesg:
usb 1-3: new high speed USB device using ehci_hcd and address 3 usb 1-3: configuration #1 chosen from 1 choice au0828: i2c bus registered tveeprom 0-0050: Hauppauge model 72001, rev B3F0, serial# 5280879 tveeprom 0-0050: MAC address is 00-0D-FE-XX-XX-XX tveeprom 0-0050: tuner model is Xceive XC5000 (idx 150, type 4) tveeprom 0-0050: TV standards NTSC(M) ATSC/DVB Digital (eeprom 0x88) tveeprom 0-0050: audio processor is AU8522 (idx 44) tveeprom 0-0050: decoder processor is AU8522 (idx 42) tveeprom 0-0050: has no radio, has IR receiver, has no IR transmitter hauppauge_eeprom: hauppauge eeprom: model=72001 xc5000 0-0061: creating new instance xc5000: Successfully identified at address 0x61 xc5000: Firmware has not been loaded previously DVB: registering new adapter (au0828) DVB: registering adapter 0 frontend 0 (Auvitek AU8522 QAM/8VSB Frontend)...

After an application open the device the first time, the module will load the firmware. You will see:

Analog Audio
To have analog audio in tvtime I am using following bash script to start the tvtime (There are two versions of SOX command - for OSS and for Alsa):
#!/bin/sh
tvtime &>/dev/null &
tPID=$!
echo "Started TVTime, PID: $tPID"
sleep 1
# For OSS:
# sox -r 48000 -b 16 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp &>/dev/null &
# For Alsa:
sox -t alsa hw:1,0 -t alsa hw:0,0 &>/dev/null &
sPID=$!
echo "Started SOX, PID: $sPID"
while true; do
sleep 1
tRUN=$( ps -p $tPID -o pid --no-headers )
sRUN=$( ps -p $sPID -o pid --no-headers )
if [ "$tRUN" = "" ]; then
echo "TVTime exited. Closing SOX and exiting."
kill $sPID
exit
fi
if [ "$sRUN" = "" ]; then
echo "SOX exited. Closing TVTime and exiting."
kill $tPID
exit
fi
done
