LifeView TV Walker Twin (LR540)

A dual DVB-T USB Receiver from LifeView.

It is supported (for further information see below).

Components Used:

Contains 2 tuners and 2 demodulators, and 1 remote control.

  • NXP/Philips 8275AC1 (tuner)
  • NXP/Philips TDA10046A (demodulator)
  • ULi M9206 (USB bridge)

The M9206 chip handles two demodulators and two tuners.

The demodulators are located at 7-bit i2c addresses 0x08 and 0x0b. The tuners are located at 7-bit i2c addresses 0x60 and 0x61.

Subsystem information:

USB id: 10fd:0514 (cold - before firmware download)
USB id: 10fd:0513 (warm - after firmware download)


Supported and mostly working. Things which work include:

  • Device is recognised and two tuners and two demodulators are attached. With the latest driver both tuners are working fine
  • Can play video streams using Kaffeine
  • Remote control initialisation and codes have been determined

Things which may not work include:

  • "scan" only finds some transponders (for Nick Andrew, at least)
  • Have not successfully used dvbstream yet (though, may be the result of incorrect settings)


This device works almost out-of-the-box if you have a sufficiently recent linux kernel.

  • Support for this device (both tuners) is the mainline Linux kernel since 2.6.23
  • Support for this device (1 tuner only) is in the mainline Linux kernel since 2.6.22
  • You can use the v4l repository from linuxtv.org for more recent changes (if any)
  • Work in progress occurs in the m920x experimental tree from http://linuxtv.org/hg/~aapot/m920x
  • Go to http://linuxtv.org/repo/ and follow the instructions for building the modules and installing


You will need to get firmware:
