Here is a list of changes between EBU Tech 3343 v3.0 and v2.0 (August 2011):
- Explanation of basic R 128, its parameters and ITU-R BS.1770 to appendices;
- Updated recommendations to the actual version of R 128 (tolerances etc.);
- Vastly expanded section on genre-specific issues (films, commercials, music);
