Abstract: A recording apparatus includes: a buffer unit that accumulates input stream data; a file recording processing unit that records a file of the stream data which is accumulated in the buffer unit and management information which is used to manage the file in a recording medium; a buffer monitoring unit that monitors a free space of the buffer unit; and a file system control unit that controls time that updates the management information using the file recording processing unit based on the free space of the buffer unit which is notified by the buffer monitoring unit.

Abstract: A method of transmitting data by which cipher-transmission of digital information data for which forbidden codes including timing identification codes are predetermined can be carried out with enciphered digital information data without containing undesirable forbidden code, in which digital information data contained in word sequence data which contain also time reference code data composed of the timing identification codes are subjected to enciphering process without producing the forbidden code to produce the enciphered digital information data which do not contain any forbidden code and then enciphered word sequence data are constituted with the enciphered digital information data and the time reference code data to be transmitted.

Abstract: Disclosed herein is a recording apparatus including: an input section configured to input data to be recorded; a data placement section configured to suffix write complete information indicating that a written state of the data written to recording media is normal, to the data; and a recording control section configured to transfer a predetermined amount of the data to which the write completion information is suffixed by the data placement section, to the recording media successively for recording thereto from a start block of the data.

Abstract: Disclosed herein is a recording apparatus including: an input section configured to input main data and added data attached to the main data; and a recording control section configured such that when the main data and the added data input through the input section have each reached a predetermined data amount, the recording control section temporarily stores the main data and the added data in units of the predetermined data amount; and that when the sum of the amounts of the temporarily stored data has reached a specific data amount, the recording control section transfers the temporarily stored data to recording media for recording thereto in a single file; the recording control section further registering management data about the recorded data to a file system of the recording media in such a manner that the management data is sorted by the data type of the recorded data.

Abstract: Disclosed herein is a recording apparatus including: an input section configured to input or generate main data and added data thereof; and a recording control section configured such that when the main data and the added data input or generated by the input section have each reached a predetermined data amount, the recording control section temporarily stores the main data and the added data in units of the predetermined data amount, that when the sum of the temporarily stored data has reached a specific write data unit, the recording control section transfers the temporarily stored data to recording media for recording thereto, and that when the amount of the temporarily stored data is less than that of the specific write data unit upon elapse of a predetermined time period since the most recent recording, the recording control section transfers the temporarily stored data to the recording media for recording thereto.

Abstract: Video data exploitation by alteration of data is prevented. An extractor 111 extracts valid video data in data 110 and predetermined data in the data. An inserter 114 inserts an arithmetic operation result of the predetermined data by an arithmetic operation unit 113 into the valid video data encrypted by an encryptor 112. An output of the inserter 114 is supplied to an extractor 144 through a transmission path 120. The encrypted valid video data and arithmetic operation resultant data of the arithmetic operation unit 113 are extracted. An arithmetic operation unit 143 executes the same arithmetic operation as that of the arithmetic operation unit 113 to data corresponding to the data used in the arithmetic operation unit 113 from the valid video data decrypted by a decryptor 141 and extracted by an extractor 144. A comparator 145 compares an output of the arithmetic operation unit 143 with an arithmetic operation result extracted from data 140.

Abstract: A method of enciphering data which is applicable to cipher-transmission of digital information data, in which the HD-SDI signal DHS is subjected to enciphering process using common key data DEY which is common to encipherment and decipherment to produce enciphered HD-SDI signal DHSE, the common key data DEY are subjected to enciphering process using open key data DOY to produce enciphered common key data DXY, and the enciphered HD-SDI signal DHSE accompanied with the enciphered common key data DXY are send to be transmitted, so that such a fear that the common key data DEY are eavesdropped on the transmission thereof can be effectively reduced.
