2.1 Objectives and basic principles
The goal of these guidelines is to achieve loudness normalisation between services in the distribution stage of the radio and television broadcast chain and to achieve loudness level equalisation between systems and interfaces of consumer equipment for radio and television reproduction. The objective is to scale down loudness differences to a level where consumers can safely switch from one channel to another and from one audio system to another without annoyance. To achieve consistent loudness levels throughout facilities, distribution and transmission networks and, ultimately, for the listener, the whole broadcast chain of production, play-out and distribution needs to be included in the scope. This document includes requirements and recommendations for set-top boxes, television sets and home theatre equipment, levels for encoding, decoding and modulation and it introduces lossless loudness normalisation in the distribution stage. The aim is to provide a consistent, higher quality of sound and thus a more pleasant listening experience for the audience
