Screen-less Navigation for High-Resolution Audio on Blu-ray Disc

The AES in Budapest saw a panel discussion lead by Stefan Bock, managing director of msm-studios, on screen-less navigation for high-resolution audio on Blu-ray disc. Panelists Jim Anderson (New York University, NY), Tomi Pietilä (Producer/Engineer, Finland), Darcy Proper (Wisseloord Studios, Hilversum) and David Walstra (Consultant AV Entertainment Industry) particularly discussed the changes and challenges of high-resolution audio on Blu-ray in hi-fi environments.

High-resolution audio, presented as uncompressed LPCM, has been waiting for a suitable transport format for some time. The Blu-ray Disc (BD) format offers such a transport and supports the necessary linear and lossless codecs as part of its basic specification. While many BD players can be found in home theater and games environments, there are some issues that need to be addressed before they can be introduced into a hi-fi environment that does not have a screen to present visual menus for audio stream setup and track selection. This recommended method specifies a structure for authoring a BD ROM to enable playback in screen-less consumer systems, and to provide simple track selection from the remote control.

msm-studios have been at the forefront of developing such a screen-less navigation, which was described and approved of in a paper AES-21id by the AES in spring 2010. With the Pure Audio Blu-ray, msm-studios have done pioneering research and development for screen-less navigation of high-resolution audio on Blu-ray. Developed in co-operation with Lindberg Lyd, the Pure Audio Blu-ray combines the Blu-ray format’s vast storage capacity and bandwidth necessary for high resolution sound (up to 192 kHz/24Bit) in surround and stereo with the easy and straight-forward handling of a CD.
