A [[DVB-T]] [[DVB-T USB Devices|USB device]] from [[Medion]].


The DVB part is supported by linuxtv.
==Using the Medion MD95700 with Suse 10.1==


==Overview==
''' ''please review this text ... thanks!!'' '''
The following kernel modules are needed for this device:
* tuner_simple
* tuner_types
* cx22702
* dvb_usb
* dvb_core
* dvb_usb_cxusb
* dib7000p
* dibx000_common
* dib0070


On a Suse 10.1 default smp kernel, the driver module [[DVB_USB#Medion_MD95700_.28DVB-T.29|dvb-usb-cxusb.ko]] is missing.
The USB box can not be used without building this module.
The sources of this driver are in the files drivers/media/dvb/dvb-usb/cxusb.*.


{{DvbDeviceList
The driver for the Medion MD 95700 is referenced in newer kernel configuration as "Conexant USB2.0 hybrid reference design support". Yast uses the term "Conexant DVB-T reference design".

==Firmware==
To build this driver:
There is a new firmware, version 1.0.2.14, for the MD 95700 from Medion.
* Install kernel-source, gcc, ncurses and optional kernal-syms
It is highly recommend to update the firmware for newer kernels.
* cd /usr/src/linux
You can download it directly: [http://www1.medion.de/downloads/index.pl?op=detail&id=2804&type=treiber&lang=de] (in German). '''Please read the Readme''' before you flash the box.
* Optional copy the current kernel configuration: cp /proc/config.gz .config
* Enable the build of the missing module:
** su
** make menuconfig
** Device Drivers -> Multimedia Devices -> Digital Video Broadcasting Devices -> Conexant USB2.0 hybrid reference design support -> build as Module
* Build either the the whole kernel inluding modules or this single module. The build process is described in /usr/src/linux/README.SUSE
* Install the module(s)
* Load the module using "modprobe dvb-usb-cxusb". On reboot, the module should be automaticallly loaded if the box is connected.
* The devices /dev/dvb/adapter0/* should be created on module load
* Configure the box using Yast -> Hardware -> Tv Card -> Add -> Other -> Conexant DVB-T reference design
* Install and configure your favorite [[Software|DVB Tv application]]


This update fixes some video problems, but it is incompatible with the old dvb-usb drivers (i.e. kernels from 2005). If you use your box under Windows, don't forget to ensure that the Windows drivers are up to date too.


==Image and sound glitches==
'''Note:''' The current Suse kernel source "2.6.16.21-0.13" has the new dvd-usb drivers included and therefore can handle boxes flashed to the firmware 1.0.2.14.
If you have a good signal but a bad image and sound quality (artifacts, sound glitches) you are affected by a bug.
Try this workaround: [http://www.spinics.net/lists/linux-media/msg14112.html]
but keep in mind that it's just a workaround, not a bugfix!


==Analog TV tuner==
The analogue part seems to be handled by a Conexant CX25842. It's kernel driver is cx25840, although the main driver for the Box isn't finished so it doesn't get detected (on 2.6.32).

Device / Model Type Hardware Firmware URL / Pictures
Comments & quirks
Medion MD 95700 4in1 USB2.0 Conexant CX22702 1.0.2.14
Inner circuits (tuner)
The box offers an X10 RF controller with remote (Medion MD1 NBC). It is supported by the ati-remote or lirc-atiusb kernel module, but only the latter is supported by LIRC - do not load both simultaneously!
It also offers an internal USB hub with four ports, of which one is available on the outside.
The USB hub, the external USB port and the RF controller work without the 12V power supply.


Firmware

There is a new firmware, version 1.0.2.14, for the MD 95700 from Medion. It is highly recommend to update the firmware for newer kernels. You can download it directly: [1] (in German). Please read the Readme before you flash the box.

This update fixes some video problems, but it is incompatible with the old dvb-usb drivers (i.e. kernels from 2005). If you use your box under Windows, don't forget to ensure that the Windows drivers are up to date too.

Image and sound glitches

If you have a good signal but a bad image and sound quality (artifacts, sound glitches) you are affected by a bug. Try this workaround: [2] but keep in mind that it's just a workaround, not a bugfix!

Analog TV tuner

The analogue part seems to be handled by a Conexant CX25842. It's kernel driver is cx25840, although the main driver for the Box isn't finished so it doesn't get detected (on 2.6.32).

LIRC configuration

  1. remove the kernel driver ati_remote when you want to use lirc. you can do it by blacklisting it or recompiling your kernel (check your distro's infos on that)
  2. set up lirc and the kernel drivers (you'll need the lirc_atiusb module) according to what your distro says.
  3. use the following for /etc/lirc/lircd.conf (or however it's named in your distro):
# brand: Medion MD1 NBC
# Made in China X10
# Medion Remote Control
# * FCC ID: B4S20018268
