Patent number: 7751693Abstract: In an image recording/reproduction method for recording image information on a recording medium by using a computer, a verify mode is set into the OFF state when recording image information on said recording medium. In addition, use as a write or read region a specified region of the recording medium which is greater than or equal to a unitary data size being handled during error correction processing to be performed when writing or reading image information on or out of said recording medium. Additionally, upon reading of image information from the recording medium, any image information that has experienced read errors will never be read again.Type: GrantFiled: October 3, 2005Date of Patent: July 6, 2010Assignee: Hitachi Kokusai Electric, Inc.Inventors: Tomomi Takada, Hirotada Ueda, Seiichi Hirai, Masahiro Kageyama, Hisao Tanabe

Patent number: 7437301Abstract: On an information registering equipment, content of interest rendered by media, such as a video image of interest distributed by TV broadcasting is captured and displayed. Position/area on the image are defined with a mouse or the like to obtain the target position/area. Information to identify the content is obtained from the TV tuner. Reference information is obtained through input means or by retrieval from the server for reference information. The obtained information specifics are transmitted to an information search equipment that in turn stores then into its database. An information viewing equipment obtains the target position/area and information to identify the content of interest and transmits the thus obtained data to the information search equipment. The information search equipment matches that data with each data record in the database and transmits reference information to the information viewing equipment on which the reference information is displayed.Type: GrantFiled: September 16, 2004Date of Patent: October 14, 2008Assignee: Hitachi, Ltd.Inventors: Masahiro Kageyama, Tomokazu Murakami, Hisao Tanabe

Patent number: 7320012Abstract: File management method having first and second processing modes for storing file type information for discrimination between first and second processing modes in recording medium as file management information associated with file for file management. In first processing mode, when data in the form of file is written on a recording medium and a write error occurs, replacement processing to another write area is performed to write the data in another area. In second processing mode, when write error occurs, the replacement processing to other write area is not performed to write the data. Method includes reading file type information associated with a file to be processed from recording medium, converting the file type from file type indicative of first processing mode to file type indicative of second processing mode, and writing the file type after conversion in recording medium as file management information associated with the file to be processed.Type: GrantFiled: April 25, 2006Date of Patent: January 15, 2008Assignee: Hitachi, Ltd.Inventors: Masahiro Kageyama, Hisao Tanabe, Tomokazu Murakami

Patent number: 7228055Abstract: To connect two divided and multiplexed streams seamlessly, a gap between video and audio playback times has to be adjusted. And, to make this adjustment, every conventional method has been required to process mass data by extracting and re-encoding the elementary streams and re-arranging the data, so that the data cannot be handled by any video cameras. However, the present invention has successfully solved the above conventional problems as follows. An audio packet disposed at the start of a following stream to be connected is replaced with a null packet if its playback start time precedes that of the video packet. Then, soundless audio packets are added at the end of the preceding stream, thereby eliminating the gap between video and audio playback times in both of the streams to realize the required seamless connection.Type: GrantFiled: December 31, 2002Date of Patent: June 5, 2007Assignee: Hitachi, Ltd.Inventors: Tomokazu Murakami, Masahiro Kageyama, Nobuhiro Sekimoto, Hisao Tanabe

Publication number: 20030204476Abstract: In a system using a terminal not connectable to a network during playback, when a user freely selects and reproduces encrypted contents, in the existing method, the initial load on the user is large and charging cannot be assured. Time counting is started when a user downloads a key generation program and accounting is performed automatically unless reset within a predetermined period of time or accounting is performed upon downloading and pay back is performed when reset within a predetermined period of time. Thus, it is possible to provide a method offering a large degree of freedom for a user and assuring accounting for a content provider.Type: ApplicationFiled: February 25, 2003Publication date: October 30, 2003Applicant: Hitachi, Ltd.Inventors: Tomokazu Murakami, Junichi Kimura, Masahiro Kageyama, Hisao Tanabe, Nobuhiro Sekimoto
