摘要： A decoding device that decodes demodulated data obtained by demodulating a quadrature modulated signal arising from digital modulation of a carrier and detects synchronization, the decoding device includes, a decoder configured to decode first demodulated data that is the demodulated data obtained by demodulating the quadrature modulated signal and is composed of in-phase axis data and quadrature axis data. The decoding device decodes second demodulated data obtained by interchanging the in-phase axis data and the quadrature axis data of the first demodulated data. A synchronization detector is configured to detect a boundary between predetermined information symbol sequences from first decoded data obtained by decoding the first demodulated data and detect the boundary from second decoded data obtained by decoding the second demodulated data. The synchronization detector selects and outputs one of the first decoded data and the second decoded data based on a result of the detection of the boundary.

摘要： When sample data is played back, audio guide data G1 and G2 and subsequent frame data are played back based on usage license information L1 contained in the sample data. When high-quality data is generated, the audio guide data G1 and G2 and the usage license information L1 are overwritten based on usage license information L2 contained in additional data. When the high-quality data is played back, audio guide data G1′ and G2′ and subsequent frame data are played back based on usage license information L3. A user is then able to identify the playback status of the sample data or high-quality data by listening to an audio guide.

摘要： It is intended to remove a risk of illegal high quality restoration while enabling trial viewing of contents such as music, to make it possible to reproduce contents with high quality by acquiring a relatively small amount of data, and to make it possible to implement hardware at a lower cost. To generate trial listening data containing dummy data, a pseudo random number R is generated first. A remainder r of R divided by 128 is calculated. The remainder r is coded and incorporated into high sound quality restoration data. A bandwidth limitation region of trial listening data is replaced by dummy data starting from its rth bit. As a result, the head position of the dummy data in the trial listening data varies frame by frame, whereby the safety of the trial listening data can be increased.

摘要： An original code string is decomposed into preview data (trial data) and high-quality data in a code-string decomposer. The high-quality data is separated into first data having an exactly or almost regular pattern and second data other than the first data by a high-quality data separator 1882. The second data is encrypted. The first data is not encrypted, or is encrypted by an encryption process other than that used for the second data. With this arrangement, important data is prevented from being deciphered.

摘要： An information transfer system for transferring the information recorded on a recording medium includes a first recording medium for recording the information, a second recording medium for recording the information, a transmission unit for transmitting the information recorded on the first recording medium to the second recording medium, and a control unit for causing a writing operation on the second recording medium based upon a control signal for a readout operation from the first recording medium. The information is read out from the first information recording medium as an information transfer origin at the same time as the information is written on the second information recording medium as an information transfer destination. This makes it possible to transfer and duplicate the information at an elevated speed substantially by the readout operation only, so that the information transfer and duplication may be expedited.

摘要： An apparatus for recording the transfer information transferred to it includes a plurality of recording media for recording the transfer information transferred from an information transfer apparatus, a writing control unit for controlling the writing of the transfer information in the recording media, and a transfer control unit for transmitting the transfer control information and an information transfer request signal to the information transfer apparatus. The transfer control information is the information for determining the transfer sequence of information blocks when the information transfer apparatus transmits the transfer information as the information blocks. The information recording apparatus transmits an information transfer request signal after transmitting the transfer control information to the information transfer apparatus. In this manner, the information recording apparatus receives the transfer information transmitted from the transfer apparatus on a information block basis and records the transfer information on the information block basis on plural recording media. It becomes possible in this manner to record information data on plural recording media not having a uniform writing speed from one recording unit to another, such as a flash memory, by parallel writing in a regular sequence, for enabling highly efficient information transfer by simplified control.

摘要： A recording medium is formed of a plurality of flash memories. A recording medium controller manages the recording status of the plurality of flash memories in units of blocks. The recording medium controller controls a data recording process so that data is recorded in such a manner that one or more parallel block sets are constructed which consist of one or more blocks the number of which is determined in accordance with a minimum number of blocks required to obtain a minimum waiting time in the process of recording data in a parallel fashion into the one or more blocks of the recording medium, and the data is recorded in the parallel fashion in the one or more blocks of the one or more parallel block sets, thereby recording data on the recording medium at a high speed. The recording medium controller also controls the data recording process so that data is recorded in such a manner that one or more parallel block sets each consisting of one or more blocks used to record the data are constructed in such a manner as not to create a significant difference in the size of a writable area available for recording data among the plurality of flash memories, and the data is recorded in the parallel fashion in the one or more blocks of the one or more parallel block sets, thereby recording data on the recording medium without creating a significant difference in the writable area size.

摘要： The simplified high-speed memory control and simplified flexible memory management are provided for an information recording/reproducing device having a recording medium having an erasure unit larger than the writing unit. A recording medium 3 is such a recording medium having an erasure unit larger than a writing unit, such as a flash memory. When recording data of a file transferred via a transfer control section 5 on a recording medium 3, a recording medium controller 2 records data beginning from the leading position of the erasure unit. Moreover, only data of a given file is recorded in one erasure unit, so that data of another file is not allowed to co-exist in one erasure unit. When re-writing file data, pre-existing files can be erased in a lump without retreating to, for example, an external buffer, thus assuring facilitated memory management, such as readout of file data.
