Sundtek MediaTV HD USB / MiniPCIe are world class ATSC/QAM64/QAM256, AnalogTV (NTSC), Composite, S-Video, FM-Radio devices which are fully supported with Linux, our technology provides support for the entire 2.6.x Linux Kernel Series, unpatched Kernels are supported from 2.6.15 on.

The driver installation is currently mainly done on the console, we are working on providing a graphical installer lateron. The driver is developed by Sundtek Ltd. The driver runs as normal application (in userspace), if unexpected problems occur the system will not be affected by it, aside of that it has the advantage that it is not bound to any particular kernel version which makes difficult compiling unnecessary.

The driver also has Closed Captioning support which complies with the requirements of the FCC
Channel 1-4 and Text 1-4 decoding.

tvtime does not comply with those requirements.

Minimum System requirements Linux 2.6.15 32 or 64 bit (older kernels need small USB framework patches), 1.5 Ghz

Supported Architectures:

* Intel/AMD x86 (32/64 bit)
* IBM PowerPC (eg. Sony Playstation 3 - first revision)
* further builds are available uppon request

This installer supports following operating systems:

* Linux
* FreeBSD 8.0
* Apple
* Solaris

http://www.sundtek.de/media (for driver releases)

Please note that the linux 2.6.27 and 2.6.28 series have a bug in the USB System wich makes the memory usage of the Linux system grow, this causes the system to run out of memory after some time. You can read more about this issue and how to fix it on the Linux USB Mailinglist, it is probably easier to use Linux 2.6.15 - 2.6.26 or 2.6.29+.

The latest driver version can be downloaded from the Driver Board (for ATSC please consider using the latest Beta driver)

open a console and run following command as root
$ chmod 777 empia_installer*
$ sudo ./empia_installer_{version you downloaded}.sh

Welcome to the EETI em28xx linux driver setup

Legal notice:
This software comes without any warranty, use it at your own risk

Do you want to continue [Y/N]:
stopping old driver instance...
installing em28xx driver to /opt
checking system... 64Bit System detected
finalizing configuration... (can take a few seconds)  
installing libmediaclient interception library

Analogue TV/Composite/S-Video

for starting analogTV with tvtime:
tvtime -d /dev/video1

by default most linux tv players do not support digital audio properly, in order to fix that problem our driver supports internal audio processing, which means that the driver automatically tries to play the available data to the default soundcard, while the TV application is just in charge of displaying the video.

(the screenshot was made with the PAL version, NTSC only supports 720x480@30 FPS)

For using the device with mplayer:
$ mplayer tv:// -tv driver=v4l2:device=/dev/video1

The driver automatically tries to figure out the correct audio playback.

For using analogue TV with vlc, just start up VLC and select the corresponding capturedevice eg. /dev/video1 in our case

FM Radio

/opt/bin/mediaclient -f 90100000 -m RADIO -d /dev/radio0 -t 0

/opt/bin/mediaclient -m RADIO -d /dev/radio0 -c internal

/opt/bin/mediaclient -m RADIO -d /dev/radio0 --mute off

for disabling audio in the background:
/opt/bin/mediaclient -m RADIO -d /dev/radio0 --mute on
