The WorldNet Oslo will be deployed by the main broadcasters of each EBU member country so more than 3,500 concerts each year can be shared in both stereo and surround sound. The platform will also facilitate the migration of the entire network to IP-based delivery in 2009.
A key requirement of the new system was to reduce the audio bandwidth for satellite delivery. “We needed to find a more efficient compression scheme that would reduce the bandwidth required but yet maintain the near-lossless quality that J.57 offered,” said Pierre-Yves Tribolet, head of Euroradio Classics.
Following the planned switch to an IP network in spring 2009, the Euroradio division will run Enhanced apt-X coding with a new stereo bit rate of 576 kbps.
