    摘要: A recording system and method, a recording apparatus and method, an input device and method, a playback system and method, a playback apparatus and method, a recording medium, and a program in which content can be flexibly protected according to whether the content should be protected. When mutual authentication is conducted with an AV board by a mutual authentication unit and when the content input into the mutual authentication unit is encrypted with a common key, an input/output controller determines that the content to be input via a bus is to be protected on the bus. The input/output controller then controls a recording/playback processor to generate protection information, indicating that the content is to be protected on the bus, and records the generated protection information on an optical disc together with the content.

    摘要: Information recording and playback apparatus, content management method, and content management program. When data of copyright-protected content is recorded in a general-purpose HDD, illegal copying of the content is prevented. Each time when content is recorded in the HDD and when content recorded in the HDD is moved to a Blu-ray disc (BD), a random number output section outputs unique verification information (a random number) and overwrites the unique verification information in the corresponding verification files of the HDD and an EEPROM. Then, when the content recorded in the HDD is to be moved to the BD, a verification section verifies the verification information (random number) recorded in the verification file of the HDD against the verification information (the random number) recorded in the verification file of the EEPROM, and permits the movement of the associated content only when they match.

    摘要: When the optical disk is at a high density, the presence of a defect of the same size can produce a great effect on data in the user data area and ID in the address area. The ID detector 23 detects the address data ID following the address marks AM stored in the address area of the optical disk 10, samples the ID following the address marks AM by using the data clock corresponding to the frequency of the wobble signals detected by the signal detector 22 to obtain ID information.

    摘要: Data recording/reproduction is carried out in a disc format such that error correction codes interleaved with respect to the direction of data on a disc are collectively blocked into an error correction unit and that the input/output order of user data in an ECC block as an error correction unit is made coincident with the direction of processing of the error correction codes. Thus, coding can be started at the time when necessary data for generating one code is transmitted, without waiting for transmission of data for one ECC block. Also, transmission of user data can be started at the time when correction of one code is completed, without waiting for completion of correction operation for one ECC block. Also, since the direction of correction codes is the same as the direction of user data, no memory for rearrangement of data is required and the hardware structure can be minimized. Moreover, since less data transmission/reception takes place between the buffer memory and the external device, bus arbitration can be easily carried out.

    摘要: First data representing user data and third data use the same error correction codes. The first data has a first error correction block structure and the third data has a second error correction block structure. That is to say, the first data and the third data have their respective error correction block structures proper for them. In particular, the recording density of the third data is made less dense than the recording density of the first data, and the number of correction codes in the first error-correction block is set at a multiple of m whereas the number of correction codes in the second error-correction block is set at n/m times the number of correction codes in the first error-correction block so that a data-piece count in the second error-correction block is also n/m times a data-piece count in the first error-correction block. As a result, it is possible to provide a good technique of recording shipping-time information onto a high-recording-density disc.
