PROBLEM TO BE SOLVED: To provide a digital broadcast system that can enhance the transmission efficiency in the case of using a single file for a plurality of scenes.;SOLUTION: When an input file storage section 4 receives contents consisting of a plurality of files, a common use file detection section 18 detects the presence of a common use file, and an input file selection section 6 takes a file shared by scenes into a scene of the earliest reproduction sequence on the basis of the result of detection by the common use file detection section 18, manages all files as a transmission file group for each scene and stores the result to a transmission file storage section 5. A carousel processing section 9 of a transmission processing section 8 applies module processing and data block processing to the file groups, a TS processing section 10 applies MPEG2-TS packet processing to the processed files, a multiplexer section 11 multiplexes the packets, a transmission channel coding processing section 12 applies proper transmission channel coding to the multiplexed packets and broadcasts the result as a broadcast wave 17 via a broadcast station antenna 16.;COPYRIGHT: (C)2001,JPO
