2.2 Loudness normalisation of television services
It is assumed in this guideline document that EBU Members’ broadcasts will be transmitted in accordance with EBU R 128. However, other broadcast stations within and from outside Europe, thematic services, play-out systems, locally-inserted advertisements, set-top box interactive applications and local broadcasting stations can use other Target Levels that result in annoying inconsistencies in loudness when switching from one service to another. To overcome this problem, lossless loudness normalisation shall be applied in the distribution stage. For file-based systems this can be done by, for example, an algorithm implemented in software. For live broadcasting, normalisation shall be based on continuous loudness measurements over a full day (24 hours)
