Switching seamlessly between random access multiplex units in a multi-angle viewing multimedia stream.

An apparatus (100A, 100B) multiplexing for multiplexing one or more coded streams with other information including the coded streams encoded with respect to each accessible access unit randomly, said multiplexing apparatus comprising images: a first unit (17, 41) for determining operable to determine delay amounts so that the delay amounts in two access units to be decoded in sequence among the access units in the coded streams become equal to each other, the amounts of delay a time delay from a time of decoding a first picture in a decoding order to a display time of a top picture in a display order; a unit (15, 42) generating operable to encode the images included in the access units and generate the one or more coded streams according to the delay amounts determined by said first unit (17, 41) determination; and a unit (18) multiplexing operable to multiplex the one or more coded streams generated by said unit (15, 42) generating and the other information, characterized in that the other information includes a flag indicating whether the two units access can be connected together without interruptions and the indicator is determined depending on whether the delay amounts of the two access units are equal to each other.
