BD players are designed to be used in conjunction with a video screen, and so screen-based visual feedback is assumed for operational control. Many audio users will still prefer the simplicity of CD operations and, in many consumer hi-fi systems, there will be no existing screen and the extra cost of providing a screen just to see the menu could make the high-resolution audio proposition impractical
It is possible, without making any changes to the BD player, to provide the necessary functionality for screen-less playback of high-resolution audio. The necessary functionality can be provided using programming that is included at the authoring stage of the disc.
The screen-less modes described in AES-21id are a function of programming during the disc mastering stage. They use the standard BD capabilities and do not seek to limit them in any way.
