METHOD FOR CONTEXT-SENSITIVE MULTI-ASPECT NAVIGATION FOR DIGITAL VERSATILE DISCS Russian patent published in 2010 - IPC H04N5/85 G11B27/10 

FIELD: physics; computer engineering.

SUBSTANCE: invention relates to digital versatile discs (digital video discs (DVD)). Selection of an audio-visual stream from several streams is realised by initially detecting a navigation data packet and at least one stream which provides information related to streams which are in synchronism with it. Based on the navigation data packet, it is determined which other streams are in synchronism with the said at least one stream, which audio data packets and sub-picture data exist in each stream, as well as which illumination information properties exist for selection among synchronised streams. At least one of the audio data packets, sub-picture data packets or illumination information properties is subjected to modification in accordance with information on at least one other synchronised stream for displaying user selected buttons for selecting between synchronised streams and/or so as to be presented with another audio content and/or sub-picture content with each stream.

EFFECT: design of a method for DVD multi-aspect navigation which enables context-sensitive interactivity and replace different audio and sub-picture data in parallel, synchronised Audio/Visual streams played from the DVD.
