Abstract
A method and an apparatus for verifying a multiplexing schedule of digital signals and an apparatus for multiplexing the digital signals are provided. The verifying method includes the processes of extracting access unit information about each decoding unit from each elementary stream of the digital signal, determining schedule information about time division of each elementary stream, based on the access unit information, and verifying whether or not the multiplexing schedule for generating the multiplexed stream is valid, based on the access unit information and the schedule information. The verifying apparatus includes an extracting section for extracting access unit information about a decoding unit from each elementary stream of the digital signal, a determining section for determining schedule information about time division of the elementary stream, based on the access unit information, and a verifying section for verifying whether or not the multiplexing schedule for generating the multiplexed stream is valid, based on the access unit information and the schedule information.
