Information record medium, apparatus for recording the same and apparatus for reproducing the same

Abstract

An information recording apparatus (SSI) is provided with: a signal process device (72) for applying a predetermined signal process to a plurality of partial record information blocks constructing whole record information (R) to thereby generate processed partial record information blocks (Sr) each composed of a plurality of predetermined information units (IU), and for generating and outputting recording position information (Sac), which is to be recorded by each of predetermined reproduction units (VOBU) composing the information units, for respective one of the reproduction units. The recording position information indicates recording positions of the reproduction units corresponding to reproduction times of the partial record information blocks within a predetermined range before and after the respective one of the reproduction units on an axis of reproduction time of each of the partial record information blocks. The information recording apparatus is also provided with; a multiplex device (75, 76) for multiplexing the processed partial record information blocks and the recording position information by each of the reproduction units to thereby output multiplexed partial record information (Sap); and a record device (77, 78) for recording the multiplexed partial record information onto the information record medium.

Description

[0001]This is a continuation application of prior Reissue application Ser. No. 10 / 273,568, filed on Oct. 23, 2002 now U.S. Pat. No. Re. 38,849, which is a Reissue application of U.S. Pat. No. 6,137,954, which originally issued on Oct. 24, 2000, which are both incorporated by reference herein in their entireties.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an information record medium such as an optical disk of a high recording density type, which is capable of recording information such as video information, audio information and the like at a high density, and which is represented by a DVD (Digital Video or Versatile Disk). The present invention also relates to a recording apparatus for recording the information onto the information record medium, and a reproducing apparatus for reproducing the information from the information record medium.[0004]2.

AI Technical Summary

Benefits of technology

Enables variegated reproduction of video and audio content on optical disks, allowing users to select options like languages and camera angles without interrupting the playback, and ensures seamless reproduction of multiple data types, enhancing user experience by maintaining continuous playback during special operations.

Problems solved by technology

However, with the conventional LD mentioned above, video image or audio sound cannot be reproduced in such an interactive and variegated manner that gives the audience several options in selecting video image to be displayed or audio sound to be played back.

Similarly, when listening to the music in a CD, the audience cannot select a preferable version out of multiple versions of the same music piece (e.g., English lyrics or Japanese lyrics).

Further, it is very difficult to store different editing versions of one movie (e.g., an original version, a theater version, a video version, etc.) on one LD or the like, because even common portions must be recorded double or more for each of these versions.

Furthermore, since it is also impossible to record multiple versions of a scene taken from different camera angles simultaneously in one movie film, the audience cannot select an image of a preferable camera angle among different camera angles.

Thus, fun and enjoyment of the audience is limited in this respect.

For example, with a slide show composed of still images and associated audio sounds, it is impossible for the audience to search only the still image corresponding to an arbitrary reproduction time.

However, in this case, since different types of informations are recorded as the video and audio informations, and due to the complication in the relationships between these informations and the control informations to control them, there is raised such a problem that video images are interrupted or the relation between the video image and its associated audio sound is destroyed especially during a special reproduction, such as a fast forwarding, a so-called time search (i.e., a search based on time), a reverse reproduction and so on.
