摘要:
A content storage apparatus capable of generating music search information while minimizing processing load. By enabling the portable playback device 5 to externally acquire and store music data, and at the same time externally acquire attribute-based music information which categorizes and indicates the stored music data according to each attribute of the music data, and use the acquired attribute-based music information to generate music search information MS to be used for searching stored music data, processing for generating music search information can be significantly reduced. Thus, music search information can be generated while minimizing processing load.

A reproduction apparatus capable of saving power consumption, wherein starting time data of a hard disk drive (HDD), is detected every time the HDD starts and, based on threshold value data generated by using a value obtained by adding standard deviation data to average value data of the starting time data, a timing of activating the HDD and starting an operation of writing song data read from the HDD to an SDRAM is determined.

A CD-R (20) in which the load when a CD player reads-in fringe data may be relieved to shorten the time until display. This CD-R is provided with contents files “00001” to “0000n”, holding respective contents, and database files TRNDB, ARNDB and ALNDB. In the contents files “00001” to “0000n”, data of the supplementary information of the contents, for each of the contents files “00001” to “0000n”, are stored, along with the contents. The database files TRNDB, ARNDB and ALNDB hold data of the supplementary information for each of the contents files “00001” to “0000n”.

A content reproduction apparatus 20 includes: a storage section 230 for storing a source-ID list L and method identification information 232; a reproduction control method determination section 240 for determining a method to control reproduction of a content on the basis of the method identification information 232; a first reproducibility determination section 242a, which is used for producing a result of determination as to whether or not a content to be reproduced is reproducible by determining whether or not a source ID attached to the content is a source ID included in the source-ID list L in case the reproduction control method determination section 240 determines that the method to control reproduction of a content is a first reproduction control method; a second reproducibility determination section 242b, which is used for producing a result of determination as to whether or not a content to be reproduced is reproducible on the basis of usage rule information described in a license issued to the content in case the reproduction control method determination section 240 determines that the method to control reproduction of a content is a second reproduction control method; and a reproduction execution section 244 for reproducing a content determined as a reproducible content.
摘要:
A content storage apparatus and method, and content storage system can offer improved content data management. When a personal computer 4 is connected to a portable reproduction apparatus 3 and executes a write process of writing music data on the hard disk drive 35 of the portable reproduction apparatus 3 or a delete process of deleting music data from the hard disk drive 35 of the portable reproduction apparatus 3, it then writes data on the outcome of the write process indicating the data number of the music data written by the write process or data on the outcome of the delete process indicating the data number of the music data deleted by the delete process, whichever appropriate, on the hard disk drive 35 of the portable reproduction apparatus 3.
摘要:
There is provided a decoder and a data recovery apparatus which has enabled power saving by setting the band to which series of processes are not carried out among the N bands to vary the processing time required for the decoding operation within the predetermined time interval and extend non-operable period, on the occasion of independently executing the predetermined decoding operation in every band for the unit data obtained by dividing the compressed data into N (integer N.gtoreq.2) bands for every predetermined time interval.

摘要:
A recording method for copying content data on a CD-R by using a personal computer. When the content data is not recorded in the CD-R, the ID of the CD-R and the data are recorded and the ID is stored in the personal computer used for recording the data. When the data is to be recorded on the CD-R, the ID is read from the CD-R. When the read ID is stored in the personal computer, the data is permitted to be recorded on the CD-R. When the read ID is not stored in the personal computer, the data is prohibited from being recorded in the CD-R.
