Have. Here, the object is composed of a data unit including MPEG encoded video information, the management information is configured to have original program chain information for managing the reproduction method of the object, and the original program chain information is 1 Movie cell information that is configured to include the above program information and one or more cell information, and manages reproduction of the object of the video information as the cell information is defined, and the movie cell information is to be reproduced to the reproduction location in the object Are configured to include entry point information relating to an entry point used for accessing, the entry point information is configured to include text information relating to the entry point, and the movie cell information includes movie cell general information. The movie cell general information including the end time information of the start time information and the corresponding cell of a corresponding cell. In an information medium configured in this way, the start time information is stored in the first four data units of the corresponding object, and the end time information is in the last four data units of the corresponding object. Stored in Here, the management information includes a playlist search pointer (PL_SRP) indicating program order, which is a parts list of one or more programs, and program information (PGI), and the playlist search pointer and the program information are primary texts. Information (PRM_TXTI) is included, and this primary text information is configured so that ISO 8859-1 or Shift-JIS kanji code can be used.
