There are two ways to look at the reception ability of NextGen: This is my own calculation for comparison purposes only;
If the data rate remains the same as ATSC 1.0 at 19.4 mb/s, the digital cliff is reduced to 11db, a 4 dB improvement.
If you keep the digital cliff at 15db, the data rate can be increased to 25 mb/s; 5.6 mb/s more than ATSC 1.0.
However, because the video compression of NextGen is about 3 times more efficient than MPEG 2, there can be several HD streams in one transmitter.
