And your assumption that bitrate and bandwidth is the same is definitely wrong! Every heard the of the distinctions between baud and bit/s? Just look at the evolution on modems from the 110bps half duplex to the 53600 full duplex (57600 is cheating because it relies on a digital line, so its not fail to compare it with earlier standards). As for DVB-T2, I will not go into the technical details , but feel free to look at: http://en.wikipedia.org/wiki/DVB-T2#System_differences_with_DVB-T > > What you (probably) meant to say was that the new encoding allows > transferring the same video quality for 30% less bit rate. > Sorry, wrong again... Unlike earlier DVB-T efforts in the world (e.g. UK's Freeview) that used MPEg2, The Israeli standard already used H.264 over the DVB-T physical layer from day one. The new transmissions will keep H.264 but will use the new DVB-T2 encoding for the HD channels. Udi
