Embodiment Construction

[0028] Such as figure 1 As shown, the information processing device embodying the present invention includes a CPU (Central Processing Unit) 11 that performs overall control and calculation processing operations on the recording and / or reproducing device 1 based on a booted program. The CPU 11 is in charge of, for example, communication operations delivered through a network, user's input / output operations, reproduction or retrieval of content from recording media, storage of content on the HDD 21 , or control operations for them. This CPU 11 exchanges control signals or data with various parts of the circuit via a bus 12 .

[0029] In the ROM 13, an operating program executed by the CPU 11, a program loader, various coefficients used for calculation, or parameters used in the program are stored.

[0030] In the RAM 20, programs executed by the CPU 11 are temporarily stored. The RAM is also used as a data area or task area required for the CPU 11 to perform various processin...

Abstract

The present invention relates to an information processing device and method, and specifically discloses an information processing method for performing processing on unit data in which one content is processed as one unit. In order to continuously reproduce and output content data, after the decryption / demodulation process of the current content data is terminated, the falsification checking process is started for the next content data reproduced after the current content data being reproduced. This eliminates the time interval when the decryption / demodulation process of the current content data and the falsification check process of the next content data are simultaneously performed, thus preventing an increase in processing load caused by the simultaneous execution of the falsification check process and the decryption / demodulation process.

Description

technical field [0001] The present invention relates to an apparatus and method for performing processing on unit data in which one content is processed into a data unit. [0002] The present invention contains subject matter related to Japanese Patent Applications JP 2003-119946 and JP 2003-119947 filed in the Japan Patent Office on Apr. 24, 2003, the entire contents of which are hereby incorporated by reference. Background technique [0003] Recently, AV (audio and video) content data, such as audio data or video data, is encoded by various methods before recording. Among various such recordings, compression codes that provide data in compressed form according to a predetermined system are well known. If content data is compression-encoded, the data amount of content as a unit is reduced, so that a limited-capacity recording medium can be effectively used. On the other hand, content data can be downloaded in a shorter time on the network. [0004] Encoding for encryptio...
