Abstract: A video recording apparatus that prevents screen malfunctions due to playback of incomplete frame image data, even when a power failure has occurred while recording frame image data received via a network to a recording medium, and incomplete frame image data has been recorded. The video recording apparatus includes a reception unit 1001 that receives management information attached to each piece of data, a first recording unit 1003 that records the received video data to the recording medium 1010, and a second recording unit 1004 that records position information of the video data to the recording medium. The video recording apparatus quickly specifies damaged data positions by referencing a file length of the video data file 1005, and a position information file 1006.

Abstract: A recording device records contents in a plurality of recording media. While the recording device records a content in a recording medium, if a free space of the recording medium runs out, an unrecorded part of the content needs to be recorded in another recording medium. In order to play back all parts of the content, all recording media in which all the parts of the content have been separately recorded are necessary. Particularly, if an internal recording medium included in the recording device has a small space and accordingly a sufficient space is secured by connecting an external removable recording medium to the recording device after the recording has started, parts of the content are separately recorded in the internal recording medium and the external recording medium.

Abstract: A recording device control apparatus that successively receives transfer requests and controls transfer of data relating to the transfer requests to and from a recording device, each transfer request including (i) area information that shows an area that is a transfer destination or a transfer source in the recording device and (ii) type information for specifying a transfer data type, the recording device control apparatus including: a reception unit operable to receive the transfer requests; a transfer request specification unit operable to perform transfer criterion judgment processing and same-area judgment processing with respect to each of specification target requests which are received transfer requests whose related data has not been transferred, and, when a targeted transfer request fulfills a condition of a negative judgment result in both of the processing, specify the related data of the targeted transfer request as a transfer target, the transfer criterion judgment processing being for judging w
