A new AES standards project, AES-X188, "Screen-less navigation for high-resolution audio on Blu-ray Discs" has been initiated. The project aims to specify a method for authoring an audio-only Blu-ray Disc to enable playback in screen-less consumer systems, and to provide simple stream and track selection using the remote control of a normal Blu-ray Disc player.
High-resolution audio, presented as uncompressed LPCM, has been waiting for a suitable transport format for some time. The Blu-ray disc format offers such a transport and supports the necessary linear and lossless codecs as part of its basic specification. While many Blu-ray players can be found in home theatre 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.
Development of this standard has been assigned to the AES standards working group SC-02-08 on Audio-file transfer and exchange. More information can be found at http://www.aes.org/standards/meetings/init-projects/aes-x188-init.cfm
