IIJ to Become the First in the World to Livestream Berlin Philharmonic Performances in the DSD™ 11.2 MHz Audio Format

IIJ's backbone network connecting Tokyo and London to provide stable livestreaming of five new orchestra performances in Concert Season 2017/2018

August 23, 2017

TOKYO-August 23, 2017-Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced that it will livestream performances of the Berliner Philharmoniker using the DSD™ (Direct Stream Digital) 11.2 MHz digital audio format within Japan. This will mark the world's first attempt at livestreaming a DSD™ 11.2 MHz digital audio source.

As the exclusive worldwide streaming partner for Berlin Phil Media GmbH - a subsidiary of the Berliner Philharmoniker, headquartered in Berlin - IIJ supports Berlin Phil Media's digital streaming service, "Digital Concert Hall," which delivers Berlin Philharmoniker concerts on the Web. By receiving original master sound of concerts from Berlin Phil Media, IIJ has been distributing them on its own high-resolution streaming service, "PrimeSeat," (*1) free of charge.
IIJ will livestream five new orchestra performances from concert season 2017 and 2018.

DSD™ 11.2 MHz offers the highest quality of any of the popular high-resolution audio formats, and it is capable of holding an enormous amount of information-as much as 16 times that of an audio CD. Playing two channels of audio (left and right) requires a bandwidth of 22.4 Mbps (*2), and IIJ's backbone network connecting Tokyo and London will be up to the task of distributing this enormous amount of live audio data from Berlin to Japan with stable quality. IIJ's high-resolution distribution service, PrimeSeat, allows consumers to enjoy performances from the greatest orchestras in the world-all in the comfort of customers' own homes.

  • (*1) IIJ is working with KORG INC., for the development of PrimeSeat's platform.
  • (*2) This is equivalent to the amount of data normally required to stream 4K video over the Internet.
