This workshop on loudness metering techniques for broadcasting will describe the basics of new standards from ITU-R and give advice on how the actual meters should be used in practice.
ITU-R has recently issued two standards, BS.1770 and BS.1771.
Both the European Broadcasting Union and the World Broadcasting Union have encouraged members to study these new standards and give advice on suitable measuring equipment.
ITU Working Party WP6J gathers broadcasters and manufacturers of equipment to further study and improve the use of loudness meters. For digital contribution and emission, levels need to be more controlled and monitored today. Between programs and within the same program the levelshift can be more than 10 dB.
