Latest revision as of 12:08, 6 October 2009
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. There is also an IR receiver which is presumably controlled by the M9206. Note: This device's USB cable comes with 2 USB plugs. This is not one plug per tuner; plug in both of them together to supply adequate power to the device.
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)
Status
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)
Driver
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
Firmware
You will need to get firmware:
- firmware dvb-usb-tvwalkert.fw from http://www.nick-andrew.net/LifeView/
People who own such a device
Feel free to add yourself here, testers will always be needed!
