ATSC Network Attached Devices

Currently there no network attached devices that are directly supported by the LinuxTV Project. However, the number of devices that become available in this hardware category is likely to expand in the near future, so it will be interesting to see if any end up falling under the umbrella of support offered by LinuxTV.

In the meantime, it is worth drawing attention to the fact that some devices in this category already work under Linux:

Air2LAN / A75 DVB ATSC Data Receiver

The 'A75 DVB ATSC Data Receiver' by Norva Technologies, along with some other Norva products, is apparently being resold by the vendor BBTI as the 'Air2LAN'. For further details, see:

HDHomeRun from Silicondust

The HDHR does indeed work well under Linux using MythTV or VLC. This interesting embedded device contains:

• twin Thomson DTF8640B NIMs, which feature the Zoran/Oren Cascade2 digital demodulator (CAS-220), and which provide support for both 8-VSB (ATSC) and 64/256-QAM (SCTE 07 Digital Cable) sources
  Note: While these NIMs do indeed also support analog reception, the HDHR device as a whole does not -- it would require something, such as an A/V decoder, that provides ADC (analog-to-digital conversion), and then likely an MPEG2 encoder to reduce the digital signal into respectable sized packets that the Ubicom processor could stream
• an Ubicom IP3023 RISC network processor, running Ubicom's own ipOS RTOS (which is loaded from a 4Mbit SST 39VF040 multipurpose flash IC). The IP3023/ipOS combination is capable of providing hardware PID filtering
• a Davicom DM9161A Fast Ethernet PHY
