  • Patent number: 8918604
    Abstract: An information processing apparatus, an information processing method and a program may provide that information to be processed by an application program recorded on a recording medium can be taken over and used by an application program recorded on a different recording medium. The application program serving as a content, a first root certificate issued to the application program, and a second root certificate issued before the first root certificate is issued to the application program may be recorded on the recording medium. The information processing apparatus, which executes the application program, creates, in the memory, a first folder for storing data to be processed by the application program, the first folder associated with the first root certificate; and copies data stored in a second folder, the second folder associated with the second root certificate, to the first folder in a case where the second folder exists in the memory.

  • Patent number: 8565425
    Abstract: There is disclosed a method for generating data for a recording medium. The method includes receiving original content data representing a plurality of still images and identifying a first subset of the still images to be recorded with copy-protection and a second subset of the still images to be recorded without copy-protection. The method also includes converting data representing the first subset into moving image data and copy-protecting the moving image data. The method also includes generating new content data, the new content data including the copy-protected moving image data and data representing the second subset.

  • Publication number: 20110320752
    Abstract: The present invention relates to an information processing apparatus, an information processing method, a program, and a recording medium in which information to be processed by an application program recorded on a recording medium can be taken over and used by an application program recorded on a different recording medium. For example, assume that three pieces of data (file a, file c, and file d) are stored in a folder 213-12 corresponding to a BD 11 of a 2009 spring version. Also, assume that three pieces of data (file a, file b, and file d) are stored in a folder 213-11 corresponding to a BD 11B of a 2009 summer version. In this case, overwrite copying is not performed on data existing in the folder 213-11, and only the data not existing in the folder 213-11 in the data existing in the folder 213-12 is copied to the folder 213-11. The present invention can be applied to a BD player or the like.

  • Patent number: 6728473
    Abstract: A moving picture recording and reproduction apparatus and method as well as a medium are disclosed by which, upon recording of a television program, representative pictures from which contents of a program can be grasped can be recorded. Frame pictures are extracted from moving pictures being recorded, and accuracy values with which a character is present in the frame pictures are calculated. Further, accuracy values with which the phase of a person is present in the frame pictures are calculated, and the levels of an audio signal corresponding to the frame pictures are detected. Then, evaluation values are calculated using results of the calculations and the detection, and a maximum one of the evaluation values is detected. Thereafter, the frame picture corresponding to the maximum evaluation value is reduced in size and recorded onto a recording medium so that it may be used as an index upon playing back of the recording medium.

  • Patent number: 6574418
    Abstract: To perform non-normal speed reproduction without preventing a user from understanding of the program content. The audio data which has been blocked into blocks of a predetermined time unit is stored in a buffer. Blocks having the level equal to or lower than a predetermined threshold value are treated as silence data, and the block numbers are stored in a silence pointer buffer. A read out address generating unit does not read out blocks which is stored in the silence pointer buffer when the read out address buffer reads out audio data blocks from the buffer. The audio data from which silence data blocks have been excluded is subjected to connection processing in a waveform connection processing unit so that noise is not generated. A skip pattern generating unit controls a video data processing unit so that the video data is sent out with skipping some video data corresponding to blocks treated as silence block stored in the silence pointer buffer.

  • Patent number: 6529679
    Abstract: The invention provides an information processing apparatus and method as well as a providing medium by which a period for reproduction of reproduction data at fixed intervals can be calculated to reproduce the reproduction data in a fixed period. First, a TOC of reproduction data is read out and a frame number of the reproduction data is calculated. Then, a readout time within which the reproduction data for one frame are read out from a recording medium is calculated. Thereafter, a sum total of reading position movement times when the reproduction data for L frames are read out is calculated. Then, a sum total of reproduction processing waiting times when the reproduction data for the L frames are read out is calculated. Then, the sum totals of the readout times, reading position movement times and reproduction processing waiting times are added to calculate a total time.
