Abstract: A broadcast storage unit 1, which receives a program to be broadcasted digitally and records the program, includes a DeMUX processing unit 12 that acquires program information concerning a program to be broadcasted, an SI information analyzing unit 15 that extracts information on a new program from the acquired program information, a recording condition setting unit 21 that reserves the new program for recording based on the extracted program information, and a storing unit 17 that records the new program that is reserved for recording.

Abstract: A recording medium has a first recording area on which recording information is recorded as a set of recording units, and a second recording area on which control information for controlling the recording information to be recorded on the first recording area is recorded. Identifying information for identifying a management condition of the recording information recorded on the first recording area is also recorded on the second recording area at every recording unit.

Abstract: An information editing apparatus for editing a reproduction manner of record information which is recorded on an information storage medium and includes at least one picture information, includes: a selecting unit for selecting a partial record information from the record information, the partial record information being part of the record information and including at least one picture information; a designating unit for designating a reproduction timing of the selected partial record information; an extracting unit for extracting the picture information included in the partial record information as a representative picture information indicative of the partial record information; and a recording unit for recording one of the extracted representative picture information and a designation information indicative of a recorded position on the information storage medium of the representative picture information and the designated reproduction timing on the information storage medium as a reproduction control info
