Abstract: An information processing apparatus includes an encoding and decoding unit for performing a data conversion process by decoding encoded still image data acquired from an information recording medium and generating moving image encoded data based on the decoded still image data, a medium control unit for performing a data re-recording process by recording the moving image encoded data, generated by the encoding and decoding unit, on the information recording medium in a predetermined data recording format, and a controller for controlling the data conversion process of the encoding and decoding unit and the data re-recording process of the medium control unit. The controller controls the data conversion process and the data re-recording process in response to user input information as to whether to execute the data conversion process.

Abstract: The present invention relates to a recording apparatus and a method, a recording medium, and a program for allowing the relative layout of data recorded on a data recording medium to be maintained on the data recording medium without having to requiring a user to perform burdensome operation. A playback control section 82 controls reading of ARI_DATA indicating an attribute of data recorded on an optical disk from the optical disk. A data-format identifying section 86 determines whether data recorded on the optical disk is a photo movie based on the read-out ARI_DATA. If it is determined that the data recorded on the optical disk is a photo movie, a delete control section 83 controls deletion of the data from the optical disk optical disk so as to delete the photo movie. The present invention can be applied to camcorders.

Abstract: A recording apparatus for compression-coding video data and recording the compression-coded video data, including an encoder compression-coding video data using interframe compression based on predictive coding for each of groups each including a plurality of pictures, a plurality of pictures including at least one independently-decodable picture; a mark information generator generating mark information indicating an access position to the video data for each of the groups; and a recording unit recording the video data compression-coded by the encoder in a recording medium is provided. When the access position is designated to one of the groups decodable without use of information on a closest past group in reproduction order, the mark information generator generates the mark information indicating a position of a top of the decodable group.

Abstract: To provide a recording apparatus for recording at least content data and reproducing control information for controlling reproducing of the content data. The apparatus includes: a recording unit recording content data on a recording medium; and a control unit making a control to generate, with respect to the content data recorded on the recording medium, a clip information file including clip information indicating attribute information on the content data, a PlayList file including a PlayList for calling the clip information, an object file including an object for reproducing the content data by calling the PlayList file, and an index file including an index table for calling the object. The control unit correlates a type, based on a purpose of creating the PlayList file, with the PlayList file as attribute information of the PlayList file so as to make a control to generate the type in the index file.

Abstract: The present invention relates to an image playback apparatus and method, and a program for enabling a quick display of a last picture of moving pictures during fast forward playback as well as a first picture of the moving pictures during fast reverse playback. Concerning GOPs from a GOP at which the fast forward playback is started to a GOP#(N?1) that is immediately prior to a last GOP#N, encoded video data of I-pictures is stacked in a stream buffer, whereas concerning the last GOP#N, the encoded video data of all frames is stacked in the stream buffer. To the last GOP#N, only I-pictures are decoded and displayed. Thereafter the I-picture and the P-pictures in the last GOP#N is decoded, and only the last picture is displayed. The present invention can be applied to DVD players or the like.

Abstract: An information processing device for executing a data recording process for a flash memory having a primary data storage region and a data storage region includes a control unit operable to detect a data recording state of the primary data storage region of the flash memory, and when the data recording state is a predefined state, to execute a data connecting process of connecting data recorded in the primary data storage region and a data writing process of writing the connected data in the data storage region.

The playback apparatus includes a storage section temporarily storing the obtained moving image data; a decoding section decoding the moving image data read from the storage section; a detection section detecting transfer rates; a storage control section controlling the storage of a number of the units; a selection section selecting one of the combinations from among the combinations indicated by the stored combination information in a predetermined procedure; an obtainment control section controlling the obtainment of the image data.

Abstract: A recording apparatus includes the following elements. A reader reads out, to a memory, image data of each representative image of a single or a plurality of playback units recorded on the disc and encoded by a predetermined encoding method. A generator decodes the image data read by the reader to generate the menu screen. An encoded data storage unit encodes the menu screen generated by the generator by a predetermined encoding method to store the encoded data in the memory. A determining unit determines whether the encoded data stored in the memory by the encoded data storage unit satisfies a preset condition. A disc recorder records the encoded data at a position of the disc determined by the predetermined format if the determining unit determines that the encoded data stored in the memory satisfies the preset condition.

Abstract: The present invention is applied to a video camera using an optical disk based on the DVD system. Data for determination changing each time data corresponding to a recording unit from a start of a recording operation until the end of the recording operation is generated based on management data recorded in a recording medium and is recoded in the recording medium 5. A type of a recording apparatus having recorded a recording unit recorded last is determined by comparing the data for determination recorded in the recording medium 5 to the management data, thereby switching a management unit.

Abstract: In the case where recording start of moving picture is instructed, whether or not operation mode at the last recording time is moving picture mode is judged with reference to information within memory. In the case where the operation mode at the time of last recording time is still picture mode, intermediate management information for performing management of extended file by still picture file is recorded to start recording operation in moving picture mode for recording VTS subsequently to intermediate management information. In the case where operation mode at the last recording time is moving picture mode, recording of moving picture is continued as VTS previously recorded.
