A hybrid [[ATSC]] [[ATSC USB Devices|USB 2.0 device]] by [[Hauppauge]].
== Overal Impression ==


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.
This is my first video capture device and I really like it. It currently works great/excellent for ATSC (digital broadcast) but, at the time of writting, it doesn't work at all for NTSC (analog TV/cable). There is a patch[http://lists-archives.org/video4linux/20859-xc5000-tuner-analog-support.html] already available that fixes this problem, but I haven't tried it. I use WinTV-HVR-950Q on very modest hardware: an old Dell Latitude D600 laptop with 2GHz/500MB connected to a 1080p LCD TV through a VGA cable. Both my TV and the WinTV are connected to an internal amplified antenna (TERK HDTVa).
This WinTV tuner is as good as my TV tuner: both found the same channels and have about the same video quality (even for 1080i broadcasts).


{{Note|This device, the HVR-950'''Q''', 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 [[Hauppauge WinTV-HVR-950|WinTV-HVR-950]] article.}}
Note that it's critical to have a fast video card. My card, ATI Radeon 9000 32Mb, is not supported by ATI anymore, so I had to use the open source radeon driver instead of ATI's fglrx. If you use the default settings for the radeon driver, you will get a pitiful 170FPS in glxgears, which is ''NOT'' sufficient for watching digital TV. But after I used this xorg.conf file[http://lambda.uta.edu/d600/xorg2.conf], I got about 1100FPS, which was sufficient. Of course, I had to do the following to get the best resolution on my TV (and a blank screen on my laptop):
<pre>
xrandr --output LVDS --off --output VGA-0 --mode 1920x1080
</pre>


{{Note|As of August 2014, The newer [[Hauppauge WinTV-HVR-955Q|HVR-955Q]] may be shipped instead of this model, the HVR-95'''0'''Q. The HVR-955Q driver is not currently as mature as the HVR-950Q driver is.}}
== Basic Installation ==


{{Note|As of 2014-08-18, Hauppauge USA officials claim that if the HVR-950Q is ordered from their website then a HVR-950Q and not a HVR-955Q will be delivered, but obviously they won't vouch for other resellers.}}
The xc5000 driver needed for this WinTV-HVR-950Q is already part of the latest Linux kernel (part of v4l-dvb drivers).

You should upgrade to Linux kernel 2.6.27.

First you need to download and install the xc5000 firmware:
==Overview/Features==

==Making it Work==

===Firmware===
In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000. Some distributions already bundle the firmware in the official repositories. Ubuntu 9.10 (Karmic) includes it by default, Fedora 16+ includes it in the default linux-firmware package, and Debian Testing (Squeeze) includes it in the firmware-linux-nonfree package.

Kernel 2.6.30 and earlier:

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

Kernel 2.6.31 and later:

wget http://www.kernellabs.com/firmware/xc5000/dvb-fe-xc5000-1.6.114.fw
mv dvb-fe-xc5000-1.6.114.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.
The firmware will be added lazily (on-demand) when you first use the driver.

====Kernel 2.6.31 firmware issues====
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)

You can set no_poweroff this way:

cat /sys/module/xc5000/parameters/no_poweroff
0 # <--- default is automatic poweroff enabled
echo -n 1 > /sys/module/xc5000/parameters/no_poweroff
cat /sys/module/xc5000/parameters/no_poweroff
1 # <--- poweroff is now disabled

This will take effect when the module is 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: [http://www.kernellabs.com/blog 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:

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

</pre>
</pre>
Connect the WinTV to a good antenna.
Then download some tools (using your distribution installer: yum, apt-get, etc):
<pre>
yum install dvb-apps mplayer
</pre>
Then scan your ATSC channels. For example, to scan ATSC channels in US do
<pre>
scandvb /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB > channels.conf
</pre>
Then copy the file <tt>channels.conf</tt> to the directory <tt>.mplayer/</tt> and test it on of one of the channels listed in <tt>channels.conf</tt>. For example, if you have a channel called KERA-HD, you do:
<pre>
mplayer dvb://'KERA-HD'
</pre>
In my case, for a 1080i broadcast, I had to use the following parameters:
<pre>
mplayer dvb://'KERA-HD' -vo x11 -framedrop 1
</pre>
because of my slow video and audio cards.


===Analog Audio===
== Useful Scripts ==
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. Also, this version disables screen saver in KDE4,
instead of using dbus interface, this could be some other command):


Instead of using special software for TIVO-like recording (such as MythTV), I use simple scripts. I first created a file in my bin directory, called favorites.txt, with mnemonics for my favorite channels listed in channels.conf (these are actual their channel numbers). Example:
<pre>
4 KDFW DT
5 KXAS-HD
11 KTVT-DT
13 KERA-HD
</pre>
and use the following script, called tape, in my bin directory:
<pre>
<pre>
#!/bin/sh
#!/bin/sh
tvtime &>/dev/null &
ext=`date +'%m-%d-%H-%M-%S'`
tPID=$!
tapeit='/tmp/tapeit-'${ext}
echo "Started TVTime, PID: $tPID"
stopit='/tmp/stopit'
sleep 1
file='~/Videos/'${ext}'-'$1
# OSS version:
pat='s/^'$1' //p;d'
#sox -r 48000 -b 16 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp &>/dev/null &
chan=`sed "${pat}" ~/bin/favorites.txt`
# Alsa version:
if [ "${chan}" == "" ]; then echo "Valid channels:"; cat ~/bin/channels.txt; exit; fi
sox -t alsa hw:1,0 -t alsa default &>/dev/null &
echo "azap -r -c ~/channels.conf '${chan}' > /dev/null & cat /dev/dvb/adapter0/dvr0 > ${file}" > ${tapeit}
sPID=$!
echo 'killall -q azap cat' > ${stopit}
echo "Started SOX, PID: $sPID"
if [ "$2" = "now" ]; then sh ${tapeit}; else at -f ${tapeit} $2; fi
# Simulator Activity (to disable Screen Saver):
if [ -z "$3" ]; then at -f ${stopit} now + 1 hour; else at -f ${stopit} $3; fi
( while true; do sleep 10; /usr/bin/qdbus org.freedesktop.ScreenSaver /ScreenSaver SimulateUserActivity; done ) &>/dev/null &
aPID=$!
echo "Started activity simulator (to disable Screen Saver), PID: $aPID"
while true; do
sleep 2
tRUN=$( ps -p $tPID -o pid --no-headers )
sRUN=$( ps -p $sPID -o pid --no-headers )
if [ "$tRUN" = "" ]; then
echo "TVTime exited. Closing SOX + activity simulator and exiting."
kill $sPID
kill $aPID
exit
fi
if [ "$sRUN" = "" ]; then
echo "SOX exited. Closing TVTime + activity simulator and exiting."
kill $tPID
kill $aPID
exit
fi
done
</pre>
</pre>

For example, to tape something on KDFW-DT (channel 5) between 5pm and 6pm you execute:
==External Links==
<pre>
[http://www.hauppauge.com/site/products/data_hvr950q.html Hauppauge 950Q product page]
tape 4 5pm 6pm
[[Category:ATSC USB Devices]]
</pre>
(note that for 1080i, you will need 6GB/hour). The result will be written in the directory Video under a name that contains date/time/channel.
Then you can use mplayer to watch this file.

Making it Work

Firmware

In order to use the LinuxTV driver, you need to download and install the firmware for the xc5000. Some distributions already bundle the firmware in the official repositories. Ubuntu 9.10 (Karmic) includes it by default, Fedora 16+ includes it in the default linux-firmware package, and Debian Testing (Squeeze) includes it in the firmware-linux-nonfree package.

Kernel 2.6.30 and earlier: 

 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

Kernel 2.6.31 and later: 

 wget http://www.kernellabs.com/firmware/xc5000/dvb-fe-xc5000-1.6.114.fw
 mv dvb-fe-xc5000-1.6.114.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

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)

You can set no_poweroff this way: 

   cat /sys/module/xc5000/parameters/no_poweroff
   0                       #  <---   default is automatic poweroff enabled
   echo -n 1 > /sys/module/xc5000/parameters/no_poweroff
   cat /sys/module/xc5000/parameters/no_poweroff
   1                       #  <---   poweroff is now disabled

This will take effect when the module is 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

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

xc5000: waiting for firmware upload (dvb-fe-xc5000-1.1.fw)...
i2c-adapter i2c-2: firmware: requesting dvb-fe-xc5000-1.1.fw

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. Also, this version disables screen saver in KDE4, instead of using dbus interface, this could be some other command): 

#!/bin/sh
tvtime &>/dev/null &
tPID=$!
echo "Started TVTime, PID: $tPID"
sleep 1
# OSS version:
#sox -r 48000 -b 16 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp &>/dev/null &
# Alsa version:
sox -t alsa hw:1,0 -t alsa default &>/dev/null &
sPID=$!
echo "Started SOX, PID: $sPID"
# Simulator Activity (to disable Screen Saver):
( while true; do sleep 10; /usr/bin/qdbus org.freedesktop.ScreenSaver  /ScreenSaver SimulateUserActivity; done ) &>/dev/null &
aPID=$!
echo "Started activity simulator (to disable Screen Saver), PID: $aPID"
while true; do
  sleep 2
  tRUN=$( ps -p $tPID -o pid --no-headers )
  sRUN=$( ps -p $sPID -o pid --no-headers )
  if [ "$tRUN" = "" ]; then
    echo "TVTime exited. Closing SOX + activity simulator and exiting."
    kill $sPID
    kill $aPID
    exit
  fi
  if [ "$sRUN" = "" ]; then
    echo "SOX exited. Closing TVTime + activity simulator and exiting."
    kill $tPID
    kill $aPID
    exit
  fi
done
