AMD ATI TV Wonder 600 USB

A hybrid ATSC USB 2.0 device by ATI/AMD.

Support for this device was added to the LinuxTV codebase on July 26, 2008 (hg 8492), targeted for inclusion in the 2.6.27 kernel. There is also a third party driver available (see the Drivers section below for details).

Overview/Features

This device supports ATSC (i.e. OTA Digital TV) and analog NTSC. It also has a connector on the side for an A/V cable dongle. The package includes a small dipole antenna and a short USB extension cable.

Components used:

  • Xceive xc3028ACQ (tuner & analog demodulator)
  • LG DT3303 (digital demodulator)
  • Texas Instruments tvp5150 (video decoder)
  • Empiatech em2883 (USB bridge and analog audio)

Identification

The device identifies itself as a "Advanced Micro Devices, Inc" and the subsystem information provided by lsusb -v is 0438:b002.

Making it Work

Firmware

In order to use the LinuxTV driver, you need to download and install the firmware. Here is the procedure to follow:

Download the firmware with something like:

wget http://steventoth.net/linux/hvr1400/xc3028L-v36.fw

copy the file so it can be picked up by the Linux kernel:

cp xc3028-v27.fw /lib/firmware

Drivers

There are two potential sources of drivers for this device:

  • Use a recent snapshot of LinuxTV's v4l-dvb drivers
    • Both analog and ATSC digital reception are supported
    • Read the above mentioned Firmware section for details on installing the proper firmware.
  • Seek out support provided by Mrec's drivers: see: mcentral

Analog Audio Issue

Analog audio appears to be problematic so you will likely need to employ SOX as a helper application, prior to starting the viewing app, in order to get any sound in popular apps like tvtime etc.

sox -r 48000 -w -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp

Note that there may be an associated delay (i.e. not in sync).

The root of the problem is that the em28xx presents itself as a USB audio device, and applications such as tvtime do not know to associate the video stream with the audio stream.

Note that Markus Rechberger maintains a version of tvtime that is patched to work around this limitation: Mcentral.de tvtime

Remote Control Support

The remote control is known to not be supported in the V4L driver. It is unknown whether it is supported in the mrec driver.
