SYNCHRONIZED STREAM PACKING

摘要

There are provided methods and apparatus for synchronized stream packing of packets that differ contextually between A/V streams in a parallel presentation. A method includes the step of identifying (210) sub-picture/subtitle packets and/or audio packets having arrival timestamps and/or presentation timestamps that match an arrival timestamp and/or a presentation timestamp, respectively, of video packets. The method also includes the step of packing (220) a Video Object Unit (VOBU) and/or a Transport Stream (TS) with the identified sub-picture/subtitle and audio packets and the video packets having the matching timestamps.
