DISTRIBUTION DEVICE, REPRODUCTION DEVICE, DATA STRUCTURE, DISTRIBUTION METHOD, CONTROL PROGRAM, AND RECORDING MEDIUM

摘要

A distribution server (1) according to the present invention acquires composition information (17) including information specifying each of a plurality of components included in acquired content and information indicating a reproduction mode of the components, and includes a composition information generation unit (15) rewriting a part of the information included in the composition information (17) in a reference format to generate main composition information and to generate sub-composition information including the information referred to with the main composition information and a distribution control unit (16) distributing the main composition information and the sub-composition information generated by the composition information generation unit (15). Thus, the composition information can be distributed with high efficiency without using on-demand distribution.
