Bitrate is the number of bits per second (usually measured in kilo
bits per second, or kbps, or sometimes mbps). This means that bit
rate and bandwidth are, for all practical purposes, one and the
same.<br></div></blockquote><div><br>I meant every word I said.<br>
And your assumption that bitrate and bandwidth is the same is definitely wrong!<br>
Every heard the of the distinctions between baud and bit/s?<br>
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).<br>

As for DVB-T2, I will not go into the technical details , but feel free to look at:<br>

What you (probably) meant to say was that the new encoding allows
transferring the same video quality for 30% less bit rate.<span class="HOEnZb"><font color="#888888"><br></font></span></div></blockquote><br>Sorry, wrong again...<br><br>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.<br>
