TVBEurope 41 Forum Loudness


A cluster of recent R128 activations suggests that broadcasters are moving rapidly towards adoption. But how long do you think it will be until we can declare that universal implementation has been achieved?


these recommendations needs to begin at source, in the production and post communities. Enforcing loudness control within the transmission chain, in playout, is necessary but complex. Schut: In all honesty, I think


the EBU overdid their recommendation by making it way too complicated and way too strict for the different platforms. I don’t care if the absolute loudness level between a digital transmission and an analogue transmission is different; almost nobody switches between them. I am interested that all sources to a particular system in the home have a balanced loudness, eg, DVD, TV and games.

Camerer: In Europe I suspect that by the end of 2013 most broadcasters will have switched. Where it will still take more time is in countries like Romania, Bulgaria, Hungary, Czech Republic, Slovakia and the Baltic States, as well as the countries of former Yugoslavia. We’ll have to wait and see how quick they step up. On a worldwide basis it will certainly need several years before we can declare that the majority has switched. Pascoe: It very much depends on the size of your universe! If you’re looking at the EBU membership, then I think that it will not be long before they’re all, at least, on track. If we include all the


commercial broadcasters, operators and CE manufacturers that make receivers for European markets, then I think we are a long way off. CE manufacturers do not like building implementations specifically for regions, so bringing together all of these requirements, on a global scale, would certainly speed adoption. Plunkett: To some extent this depends upon what action has already been taken to address loudness in a given territory. The major UK broadcasters have introduced loudness control measures extensively in recent years and this has been reflected in the level of viewer complaints. Ironically, the

introduction (and compliance with) R128 could mean increased overall costs for those countries and broadcasters who acted early through self-regulation. Carroll: Ultimately,


consumers will be the judge of this. As for universal implementation, I think this will be a continuous battle that will pit compliance (relatively easy) against quality (relatively difficult).
