If you are only reading from a NAS or other type of network file server info that you are able to process later with the Pi, then you are very right, Fast Ethernet would be enough. But if, as I do, you tend to rip and encode your HD material (Blurays, 4Ks, etc) in some high profile encoding variants (x264 beyond main profiles, x265, etc) then most of the time the RaspberryPi won't have enough horsepower to do the decoding (at least last time I checked) so a simple, but network demanding, solution is to do the decoding and streaming using something like the excellent DLNA compliant Universal Media Server to push the video to the Pi from a beefier file server. Video will still be the same but its decoded size will increase by some order so the need for a lot more bandwidth will be inminent. I know this is a too specific need so that's why I'm not holding my breath but I believe that the sub $100 gigabit htpc is the ultimate gamechanger into the HD-in-every-room niche (that or an even better codec :) ) Regards, Carlos. > TTYL > > -- > http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
