The AV7710 and AV7111 ARM-based MPEG2 Decoders have been designed by Texas Instruments. Discontinued. Has some serious design limitations, the most important is probably that you are not able to get the unmodified, original Stream from cards using this decoder without hardware modifications. There have been reports from users of these cards on the linux-dvb Mailinglist all the time, this piece of hardware is a quite sensible beast and easy to hang. Some cards with these chips have thermal problems. On the other hand these cards have the adventage that a relativly slow computer beginning at 400MHz (less noise) is able to to record and play MPEG streams.
Used in Technotrend-designed Cards, namely the WinTV-Nexus-S and the Technotrend/Fujitsu-Siemens Rev 1.3/1.5/1.6/2.1/2.2 DVB-S/C/T. Unfortunally VDR, one of the most sophisticated Linux-STB software projects has been designed around these designs. Since a while the VDR Software Decoder Plugin is available for VDR but unfortunally not yet installed by default.
