The content reproduction device receives, from a server, information for indicating the location of content reproduction control information that is required for acquiring the content reproduction control information, and acquires the content reproduction control information from the server. Then, the content reproduction device extracts AV data and clip identification information for specifying clip information for managing the AV data. Then, the content reproduction device converts a predetermined part of the information for indicating the location of the content reproduction control information by applying the clip identification information and a predetermined conversion rule, generates information for indicating the location of the clip information and the AV data, and acquires the clip information and the AV data from the server.

Content reproduction system, content reproduction method, content reproduction device, and server

A digital broadcasting system capable of quickly acquiring long term program information. An SI generating part SG generates a long term program information S_EIT which is multiplexed in a transport stream TS only. The SI generating part SG gives information on whether the long term program information S_EIT is present or not for each service to other SI generating parts SG and SG The SI generating parts SG and SG multiplex the given presence information in transport streams TS and TS In this way, the presence information is multiplexed in all the transport streams. Therefore, the presence information may be acquired whichever transport stream is being received. If the presence information is retained beforehand, the information may be quickly used as required.
