Front view of a Hauppauge WinTV-HVR-1250

The Hauppauge WinTV-HVR-1250 is an ATSC PCIe card from Hauppauge. While the card's digital TV functionality has been supported under Linux since kernel 2.6.27, analog support is not yet implemented.

Overview/features

The HVR-1250 is also known by its codename Coram.

Components used

  • Likely a NXP/Philips TDA18271 (tuner for analog)
  • Microtune MT2131 (tuner for digital)
  • NXP/Philips TDA8295 (analog IF demodulator)
  • Samsung S5H1409/Conexant CX24227 (digital demodulator)
  • Conexant CX23887 (A/V decoder and PCIe bridge)

Identification

It has a Subsystem ID of 0x7911.

Power draw

Based on measurements with a Kill-A-Watt and two cards plugged in versus not, each card seems to draw about 6 W, even when idle.

Making it work

Firmware

No firmware is needed for ATSC/QAM functionality.

Drivers

The cx23885 driver has been upstream since kernel 2.6.27, so it should be available in some newer distribution kernels. Otherwise, get the latest cx18 driver. Then, inside the cx18- directory, run the following commands as root: 

make

make install 

modprobe cx23885


Known issues

If you are using SUSE 10.3, on some systems it will hang on dvbscan as soon as it finds a signal. If you encounter this issue, compile and install the 2.4.24-3 kernel. Then recompiling the cx18 against it to fix the issue.

PCI: Setting latency timer of device 0000:03:00.0 to 64

Remote control support

The IR remote is controlled through the cx23885 chip, which is not currently supported in the driver.

Testing

Use scan to get the initial channel list required by azap. Use azap to tune to the desired channel. Use mplayer to watch the channel. Be sure to copy the channels.conf file from the initial scan to your ~/.mplayer directory. 

mplayer dvb://"Channel name"
