Summary: | Selection of an audio-visual stream from among a plurality of streams occurs by first detecting a navigation packet within at least one stream that provides information concerning the stream, as well as those streams in lie in synchronism therewith. From the navigation packet, a determination is made which other streams lie in synchronism with the one stream, which audio and sub-picture data packets exist in each stream, and as well as which highligh t information properties exist for selecting among the synchronized streams. A t least one of the audio data packets, sub-picture data packets, or highlight information properties undergoes modification in accordance with information about at least one other synchronized stream to allow display of a viewer selectable button or the like to select among the synchronized streams and/or be presented with differing audio and/or sub-picture contents with each stre am. |
