Patent number: 7558464Abstract: Provided are a data editing apparatus, a data editing method and a data recording/reproducing apparatus which can easily reedit edited data recorded on a nonlinear-accessible recording medium. When a start point (IN point) or an end point (OUT point) of partial data of edited data to be reedited is specified, a controller controls a recorder and reproducer and HDDs so as to reproduce material data containing the partial data to be reedited in synchronization with operation for changing the specified start or end point of the partial data. Moreover, when operation for determining a new start or end point is performed in a state in which the material data is reproduced in synchronization with changing operation, the controller reedits the edited data in accordance with determining operation. During reediting, the controller reedits data on the basis of a temporary file. The controller reedits data while reproducing the same reproducing state as the reproducing state after reediting.Type: GrantFiled: December 29, 2004Date of Patent: July 7, 2009Assignee: Sony CorporationInventors: Masakazu Murata, Ichiro Fujisawa

Patent number: 6754434Abstract: An AV data recording/reproducing apparatus which has a recording section for recording AV data, e.g., a disk array section. Each frame unit is edited to generate editing result information. The AV data is read from the disk array section on the basis of the editing result information to reproduce the edited AV data. A command analysis section receives various linear editing commands generated by a linear editing machine for generating editing information and from which a command is produced to generate the editing result information. Thus, an editing operation using a familiar linear editing machine can be performed.Type: GrantFiled: September 24, 2001Date of Patent: June 22, 2004Assignee: Sony CorporationInventors: Ichiro Fujisawa, Yoshizo Mihara, Masaki Hirose, Kazuo Kamiyama

Patent number: 6744969Abstract: A data recording and reproducing apparatus has facilities for recording and reproducing, inputting and outputting, and editing data and can perform edits by itself. The data recording and reproducing apparatus records AV data inputted from an input port on HDDs by using a recorder and reproducer, and outputs data reproduced from HDDs by the recorder and reproducer through an output port. In an editor inputted is data inputted from outside and data reproduced by the recorder and reproducer. The editor performs edits on at least either of the data above by using a matrix switcher and an audio mixer provided therein. A special effector is utilized as necessary. The editor can output data obtained through editing processing to a switch.Type: GrantFiled: November 8, 1999Date of Patent: June 1, 2004Assignee: Sony CorporationInventors: Kazuo Kamiyama, Makoto Tabuchi, Masakazu Murata, Shinichi Morishima, Yoshiharu Yamashita, Ichiro Fujisawa, Hiroshi Masuda, Tatsuo Tsukida, Yoshizo Mihara

Patent number: 6253232Abstract: A control command attaching the same identifier to related commands is input from an application to an AV data processing control device. Further, a command for linking this identifier and a trigger generated by a contact input-1 is input. When the contact input-1 is generated, all control commands containing the identifier are executed. Further, when the link of the contact input-1 and the identifier of the control command is invalidated, even if the contact input-1 is generated, none of the linked control commands are executed. The execution of the control commands is carried out by controlling the controlled devices by the IDCs.Type: GrantFiled: March 24, 1997Date of Patent: June 26, 2001Assignee: Sony CorporationInventors: Norikazu Ito, Tsutomu Yamamoto, Taro Shigata, Shintaro Mizutani, Yusuke Tani, Ichiro Fujisawa
