Time Warner is filing patents (EP 971 354 and 357) on a clever way to make
DVD movie discs play in many languages. DVDs store moving pictures and a
soundtrack that mixes music and dialogue. Warner exploits the fact that most
movies have continuous music, with intermittent dialogue and pauses. The new
disc will have music on one track, with several dialogue-only tracks in
different languages. The player mixes the user’s preferred language dialogue
with the music. The dialogue is only recorded when necessary, with no pauses,
leaving one disc able to carry a dozen soundtracks.
