Abstract: A package medium and an additional content are always managed integrally so that an original content recorded in the package medium can always be used along with the additional content. The additional content using a virtual package function specified as an expanded function of Blu-ray is managed. An additional content management device comprises an additional content acquiring portion which can be applied to, for example, a recording/reproducing device (10) and acquires additional content stored in an external storage portion, and an additional content recording portion which stores the acquired additional content in a predetermined recording medium. The additional content recording portion detects a hybrid Blu-ray disk (BD) (20) provided with both of a data-read-only ROM area (21) and a data-writable recording area (22), and records the additional content, acquired by the additional content acquiring portion, in the recording area (22) of the BD (20).

Abstract: In order to receive an image file by a recorder, a user conventionally should explicitly switch the system state to a state for data reception such as an operation for starting communication software and an operation for temporarily switching to a wait screen which can perform a file reception process. In order to solve the aforementioned problem, it is possible to provide an electronic device which identifies the attribute of a received file and a process being executed and performs a process in accordance with them. For this, it is possible to automatically perform an operation based on not only the file type but also the program being executed by the electronic device. Thus, it is possible to execute a desired process without requiring a complicated operation by the user.

Abstract: A sub-sampling portion (101) sub-samples images of data corresponding to the left and right viewpoints. A joining method selector (104) selects the joining method that minimizes the discontinuity at the boundary in the joined image when the sub-sampled images of data are joined. A joining portion (102) joins the plurality of images data, based on the selected joining method. An encoder (103) encodes the joined image data, and a joining method encoder (105) encodes the information of the joining method. A multiplexer (106) multiplexes these pieces of coded data. In this way, the continuity of the joined image is improved, whereby the coding efficiency is enhanced.

Abstract: A moving image/audio recording apparatus in which failure of recording due to erroneous operation and operation timing deviation can be prevented is implemented. Moving image data and audio data prior to the start of recording are multiplexed by a multiplexing unit 103. The multiplexed data is temporarily stored in a built-in memory 104. A control unit 106 which has received an instruction to start a going back recording changes the going back recording start time to the time subsequent to the time when the encoding conditions or channels are changed to those at the time of the instruction to start recording if the encoding condition or the channel at the time which goes back by a period of time preset as the going back time is different from that at the time of the instruction to start recording and consecutively reads out the multiplexed data from the memory 104 for recording them in a recording unit 105 via a changeover switch 108.
