Music platform uses efficient audio format
Loudeye is deploying Coding Technologies MPEG-4 aacPlus audio format into its mobile music platform as an option for operators worldwide.
aacPlus is regarded as the most efficient audio compression technology available today, as proven in many third parties tests conducted by independent organisations such as the EBU (European Broadcasting Union), MPEG (Moving Pictures Expert Group), or the IRT (Institut fur Rundfunktechnik).
Specifically for 5.1 surround, aacPlus provides at 160Kbit/s the same audio quality as competing technologies at 384Kbit/s.
This level of efficiency offers broadcasters and network operators a significant competitive edge compared with those deploying legacy compression technology.

Kits speed surround-sound development
Software development kits combine MPEG Surround technology with the world's most efficient audio codec MPEG-4 aacPlus.
In order to instantly reach the installed base of home theatres Coding Technologies offers in co-operation with its partner DTS a combined aacPlus/DTS transcoding solution for consumer set top boxes.
The solution operates an aacPlus multichannel decoder together with a high-quality DTS encoder which outputs digital multi-channel audio directly in the DTS surround sound format to an AV home receiver.
The aacPlus/DTS audio solution allows digital broadcasters to deliver multi-channel audio in the highly efficient aacPlus format while simultaneously reaching the complete audience of 60 Million DTS enabled surround sound systems already installed in homes.
The availability of Tandberg's EN5990 professional encoder together with HDTV single-chip set-top-box decoder solutions from major suppliers such as STMicro and Broadcom enables broadcasters to deploy aacPlus for multi-channel audio, using the transmission spectrum most efficiently throughout the whole signal chain from contribution, through distribution, to emission.
The EN5990 accepts the Dolby input formats for transcoding to aacPlus, making the integration into the signal chain as easy as possible.
"The aacPlus is a great audio codec, and the aacPlus/DTS transcoding solution will put the multichannel audio lid on HDTV broadcasting", says Roger Bolton, Vice President of Business Development at Tandberg Television.
"Now that all the components of aacPlus are available it makes sense to include it in our latest generation of HD AVC encoders".
"We were really impressed by Coding Technologies' embedded implementation in terms of both, audio and software quality".
"This has enabled a smooth and painless rollout process".
"MPEG-4 AVC and aacPlus complement each other in an ideal way", adds Stefan Meltzer, Vice President Broadcasting/Consumer Electronics.
"Tandberg is best known for top-notch products in the ultimate broadcast league, which is relying on a transparent and competitive market place".
"We believe this is best guaranteed by open standard technologies, which are now available for HDTV across the whole chain, and in best quality".
