Patent number: 7398010Abstract: An information record medium (1: DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80), and performs a reproduction while moving the read device along the record track at a predetermined reading linear velocity. The record information is divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by the information reproducing apparatus, recorded on the record track. Lowest reading rate information (212) indicates a minimum requirement of a reading rate for the information reproducing apparatus to reproduce a reproduction unit, which comprises at least one of the first data groups and which is to be reproduced by the information reproducing apparatus such that a sequential logical meaning of the reproduction unit is continuous.Type: GrantFiled: March 27, 2002Date of Patent: July 8, 2008Assignee: Pioneer Electronic CorporationInventors: Akihiro Tozaki, Tokihiro Takahashi, Hidehiro Ishii, Junichi Yoshio, Hiroshi Nakamura, Takao Sawabe, Yoshiaki Moriyama, Kaoru Yamamoto

Patent number: 7330643Abstract: An information record medium (1: DVD) has a record track (1a) to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80) and reproduces audio information by a predetermined audio frame unit while relatively moving the read device along the record track recorded with at least the audio information by the audio frame unit. A plurality of audio packets (43, 202) are arranged along the record track, in each of which audio information pieces (207) constructing the audio information sampled by a predetermined sampling frequency and audio control information (203) for controlling a reproduction of the audio information pieces by the information reproducing apparatus are respectively recorded.Type: GrantFiled: June 3, 2003Date of Patent: February 12, 2008Assignee: Pioneer Electronic CorporationInventors: Takao Sawabe, Tokihiro Takahashi, Junichi Yoshio, Hidehiro Ishii, Hiroshi Nakamura, Kaoru Yamamoto, Akihiro Tozaki
