  • Publication number: 20120315017
    Abstract: A technique for achieving secure content distribution with increased copyright protection is disclosed. A content delivery apparatus is network connected to in-home/out-home content reproducible receiver devices, including digital TV sets, mobile phones or the like. The content delivery apparatus includes an optical disk drive, a built-in large capacity storage, a content list transmission unit responsive to receipt of a content list acquisition request from a content receiver device, for transmitting a list of contents recorded on an optical disk loaded in the optical drive and stored in the storage, and a content transmission unit responsive to a content and storage and for delivering it to the receiver. In cases where the content demanded is on the optical disk, if the receiver is currently outside an architectural structure with the apparatus installed therein, the content delivery to such receiver is prevented.

  • Publication number: 20120311626
    Abstract: A distributing apparatus including a communication processor unit to execute transmission of data between a content receiving apparatus connected through a network; a content list producer unit to produce an optical disc content list for when loaded in the optical disc drive apparatus, while to produce a recording medium content list when the optical disc is not loaded; a content list transmitter unit; a content transmitter unit; an authenticator unit; a key producer unit, which is configured to produce key information necessary for encoding the content(s) to be transmitted by the content transmitter unit; and an encoder unit, which is configured to encode the content(s) with using the key information in the key producer unit.

  • Patent number: 8224149
    Abstract: A record/reproduction apparatus capable of performing record-reproduction with high definition and standard definition appropriately records information, and includes: at least one of a display unit and an output unit to an external display device; a hard disk drive; and a disc drive corresponding to record-reproduction using a disc for record-reproduction in a high definition mode and a disc for record-reproduction in a standard definition mode. With the configuration, the record/reproduction apparatus performs a display on the display unit in the high definition mode or a display-output to the output unit in the high definition mode at activation, recognizes one of the hard disk drive and the disc drive as a record medium after the display-outputting, and sets a record mode to one of the hard disk drive and the disc drive based on a result of the recognition.

  • Publication number: 20110235481
    Abstract: A storage system, which includes a plurality of ODDs, is configured so as to easily retrieving a predetermined file from files stored in a plurality of optical discs. The storage system includes a storage controller connected to the plurality of ODDs and a nonvolatile memory via a storage bus. Each of the optical discs mounted in the ODDs has a file system representing the storage structure of files stored in the optical disc. The nonvolatile memory stores copies of the file systems of all the mounted optical discs. A user refers to the file system stored in the nonvolatile memory to retrieve a file. When an optical disc is ejected, the optical disc stores copies of the file systems of the other optical discs and is ejected. If the optical disc is installed into another storage system, the user can search for a file stored in the other optical discs.

  • Publication number: 20100254456
    Abstract: An encoding device is a device for encoding a moving image and includes: an imaging unit that shoots a subject; an encoder circuit that encodes an input moving image; a stream buffer that accumulates the encoded data; a network circuit that transmits the encoded data in the stream buffer to a network; and a read position skipping unit that, when an accumulated amount of the accumulated data, which has been accumulated in the stream buffer, is greater than or equal to a threshold value, transmits the encoded data to the network after advancing a read position at which the encoded data is to be read to, for example, the head position of the latest I-picture.

  • Publication number: 20100118180
    Abstract: The present invention provides an imaging device that reduces its power consumption and prevents an upload failure due to power insufficiency when it uploads movie content. The imaging device includes a power supply identification section which determines whether a drive power supply is a battery or an AC power supply, and a remaining battery power value acquisition section which, when a battery is employed as the drive power supply, acquires a current remaining battery power value P and compares it against a predetermined value P0. When the current remaining battery power value P is less than the predetermined value P0, an operation for movie content transmission by a communication module section is interrupted. In addition, an interruption information storage section stores the information about an interruption point of content to be interrupted.

  • Publication number: 20090161507
    Abstract: Provided is an information recording/reproducing apparatus which suppresses consumption of a battery and prevents wasteful power consumption in the case of failing in recording and dubbing operations, including a signal processor which processes video or audio elementary stream supplied from the outside; an encoding unit which compresses information generated by the signal processor; a first recording medium which records the information compressed by the encoding unit; a connection which connects an external first power source; an internal second power source which is different from the first power source; and a controller which, when detecting a writing failure of the compressed information in the first recording medium, stops a power supply from the second power source when a recording operation of the compressed information in the first recording medium is operated only by the second power source.
