摘要： The present invention provides a data processing method and apparatus capable of shortening the processing time required when editing previously encrypted track data. An example of a transfer of audio track data between a portable player and a storage device is provided. The track data is comprised of one or more parts, each of which in turn is comprised of a series of data blocks. Each block of the track data is encrypted prior to transfer using a block key. The block keys are determined in such a manner that subsequent editing of the track data which results in redistribution of the parts does not require full decryption of the data.

摘要： A recording apparatus for facilitating data erasure operations involving data recorded on a recording medium. Each piece of data recorded on the recording medium may be examined to determine whether it is rerecordable by determining whether the data is already stored in another storage medium. When data erasure is requested, erasure processing may be controlled in accordance with the result of the determination. For example, original data based on data captured by a microphone or a camera (namely, non-rerecordable data) may not be erased (without specific approval by the user). Conversely, rerecordable data copied from another recording medium such as a CD may be erased.

摘要： A memory unit such as a memory card is removably attachable to a data processing unit such as a digital video recorder or an audio recording/reproducing unit. The memory unit includes a non-volatile memory, a security unit for protecting the security of data stored in the non-volatile memory, and an interface that receives control data from the data processing unit. The control data is either first control data for a read or write operation with respect to the non-volatile memory, or second control data (different from the first control data) for a security operation of the security unit. Thus, a security-type memory card is compatible with both a security type and a non-security type data processing unit.

摘要： A transfer protocol in a transfer system adapted for transferring compressed audio signals in a compressed form for recording on a recording medium is disclosed. The management data for managing compressed audio signals recorded on the recording medium are generated responsive to the information sent from the server in order to generate the management data without exchanging the management data between the server and the client. A transfer system in which, if data are previously recorded on the recording medium loaded on the client side, the management data can be edited for additionally recording data on the recording medium without modifying the compressed audio data and management data already recorded on the recording medium, is also disclosed.

摘要： A disc recording apparatus which uses a disc recorded with address data beforehand and writes the TOC (information about recorded data) in a predetermined area on the disc. When a predetermined key is operated during recording, an address on the disc corresponding to an operation point of the key is written to the predetermined area as the TOC, generating positional information for data retrieval which substantially has no offset from a marker point on the disc. In reproduction, the TOC is read before starting reproduction, so that a desired marker point can be detected promptly based on the positional information of the TOC data.

摘要： A reproducing apparatus for a recording medium such as an optical disk, includes a head, a memory, and a controller. The head is relatively moved with respect to the recording medium so as to read audio data recorded on the recording medium. The memory temporarily stores the audio data read from the recording medium. The controller controls to write the audio data into the memory and to read the audio data stored in the memory. The controller controls to write the audio data into the memory and to read the audio data therefrom in such a manner that a writing speed of the audio data read by the head becomes higher than a reading speed of the audio data stored in the memory. When a highspeed reproducing operation condition is set, the controller intermittently reads the data from a position separated from a preselected address by using the audio data previously stored in the memory, so that a highspeed reproducing operation process is executed. Also, after the highspeed reproducing operation process based on the audio data previously stored in the memory has been complete, the controller relatively transports the head at a high speed with respect to the recording medium, whereby the highspeed reproducing operation process for the audio data , which is read out from the recording medium to be written into the memory is carried out.

摘要： A method for fast playback of a disc in a cue or review mode to reproduce therefrom audio data compressed and recorded burstly by a predetermined amount as a unit. The method comprises predetermining a unitary block of data which consists of n times (where n is a positive integer) the decodable minimum unitary amount of the compressed data; sequentially extracting, out of the informationally continuous data of plural programs on the disc, the data of the unitary block at an interval of m unitary blocks (where m is a positive integer) in the forward or reverse direction of the continuity of the data; and reproducing the sound from the extracted data. By repeating such playback operation, the audio data of the plural programs can be reproduced in the cue or review mode at a speed higher than the normal playback speed.

摘要： A reproducing apparatus of a recording medium, which has address data recorded thereon, a set of data discretely recorded in a plurality of small recording areas thereon, and information indicative of connective relationships between the small recording areas recorded thereon. The reproducing apparatus includes a readout device, a memory, and a controller. The readout device reads data and address data recorded on the recording medium. The memory stores the information indicative of connective relationships between the small recording areas in the data read by the readout device. The controller controls the readout device in high-speed reproduction to repeatedly make an access in accordance with the information stored in the memory and read the data stored in the small recording areas in units of a predetermined data amount. The controller further executes control, when the readout device has moved to a position outside a preceding small recording area after an access, so that the read means will access a subsequent small recording area in a connective relationship with the preceding small recording area. When the address corresponding to the position in the subsequent small recording area, reached after this accessing operation is within a predetermined range of the start address of the subsequent small recording area, then the readout device reads data from the recording medium starting at the position reached.
