摘要： A center (content supply center) (1865) for storing and managing contents, and user terminals (1861 to 1864) used by respective users are connected via networks (861 to 867). The center (1865) sends signals of contents for trial viewing/listening to the user terminals for free or at a low price. The user terminals (1861 to 1864) can receive the signals of the contents for trial viewing/listening and select and purchase only the content that the user likes from the received contents so as to reproduce the content with high quality. This enables trial viewing/listening. It is not necessary to download a large quantity of data with high quality from the content supply center or the like and there will be more opportunities of content purchase.

摘要： A signal (801) of a first code string made through replacing a part of a code string of a predetermined format with dummy data is sent to code string rewriting means (1802) via code string resolution means (1801). A signal (806) of a second code string for complementing the dummy data part in the signal (801) is sent to the code string rewriting means (1802) via control means (1805) and the dummy data in the first code string is rewritten to the second code string. At the time of trial viewing/listening, a signal (802) from the code string resolution means (1801) is selected by a switch (1808), and when the second code string (806) is acquired through content purchase, a signal (803) from the code string rewriting means (1802) is selected by the switch (1808). Thus, trial viewing/listening of a content such as music is made possible while the possibility of decryption is eliminated. By acquiring a relatively small quantity of data, reproduction of a high-quality content is made possible.

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 information transfer system comprises a random accessible recording medium, a request information input section connected to a detachable information recording device, and an information output section connected to the detachable information recording device, thus to output, through the information output section, information read out at random from the recording medium on the basis of request information input through the request information input section. The information recording device stores information input through an information input section into a temporary recording section thereafter to record a recording medium comprised of a plurality of recording medium pieces, thereby making it possible to correctly record information at a high speed even in the case where a recording medium having relatively low write speed is employed. Moreover, the information transfer system sequentially transfers information stored on the basis of an information transfer request signal which requires information transfer from information recording devices having a variety of memory structures and adapted for recording/reproducing input information. The information transfer system carries out a control to record input information in parallel in a traversing order with respect to a plurality of recording medium pieces, thereby making it possible to record information in parallel by simple control with respect to a variety of information recording devices constituted with a recording medium in which the write time is not fixed. Thus, this information transfer system makes it possible to transfer information at a high speed by simple hardware.

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： 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 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.
