Patent number: 11907533Abstract: An archiving apparatus that realizes high-speed seek processes and the like by setting a logical object table for each container file with a predetermined size, and closing the container file under a predetermined condition is provided. A data processing section that executes control of access to a recording medium generates a logical object table for managing a container file including logical objects which are recorded data units, and records the logical object table on a memory. In a case where a prescribed condition is satisfied, for example, the container file size has become equal to or larger than a prescribed end reference value, and so on, while a process on the container file is being executed, the logical object table is read out from the memory, and recorded on the recording medium, and the container file is closed.Type: GrantFiled: November 21, 2019Date of Patent: February 20, 2024Assignee: SONY GROUP CORPORATIONInventors: Hisao Tanaka, Tomotaka Kuraoka

Patent number: 8436921Abstract: A picture signal processing system includes a playback apparatus and a display apparatus connected via first and second communication units. The playback apparatus receives a video signal made up of source data generated by moving giant image data in a constant direction at a constant speed, wherein the giant image data has a number of pixels far greater than the number of pixels in a display region. The playback apparatus reads source data speed information stored in the video signal header, and transmits the video signal and the speed information to the display apparatus. The display apparatus references a table to determine how to process the video signal on the basis of the speed information, processes the video signal, and then displays the processed video signal.Type: GrantFiled: September 18, 2009Date of Patent: May 7, 2013Assignee: Sony CorporationInventors: Naomasa Takahashi, Jun Hirai, Tomotaka Kuraoka

Patent number: 8295138Abstract: The present invention allows the usability of a write-once recording medium to be enhanced. The write-once recording medium is provided with an ordinary recording/reproduction area, an alternate area, a first alternate-address management information area (DMA) and a second alternate-address management information area (TDMA). In addition, written/unwritten state indication information (a space bitmap) is also recorded. The second alternate-address management information area is an area allowing alternate-address management information recorded therein to be renewed by adding alternate-address management information thereto. In addition, the written/unwritten state indication information indicates whether or not data has been recorded in each data unit (cluster) on the recording medium. Thus, it is possible to correctly execute management of defects and properly implement renewal of data in the write-once recording medium.Type: GrantFiled: September 23, 2011Date of Patent: October 23, 2012Assignee: Sony CorporationInventors: Tomotaka Kuraoka, Shoei Kobayashi, Mitsutoshi Terada
