摘要:
A reproducing apparatus operable to move data that is coded and managed for copyright protection after evaluation an encryption key and permitting its movement based on a result of the evaluation, to copy data that is recorded in a server to a terminal apparatus, and, cause the terminal apparatus itself to reproduce the data and, where a terminal apparatus is connected to the server to, render data on the server reproducible.

摘要:
A method and apparatus to simplify work to edit sub data by: recording one or a plurality of main data, recording management data for controlling the main data, recording one or a plurality of sub data related to the main data and sub management data for controlling the sub data on a recording medium; and linking the sub data and the sub management data so that they can be referenced from the management data.
摘要:
When advertising information is included in a received broadcasting wave, viewer attributes which have previously been registered in an IC card is collated with a target ID added to the advertising information, and the advertising information (icon) in which both of them coincide is selected and displayed (S3, S4). When there is a requesting operation of detailed information, the detailed information is obtained by link information. The detailed information can be obtained from the broadcasting wave (S11, S12) or can be obtained from a homepage via the internet (S17, S18). The detailed information is displayed in place of the picture plane of a program. When a viewer requires to finish the display, the display of the detailed information is finished (S14, S20). When the detailed information is displayed, the presence of the request for the detailed information is recorded as a history.

Even if a read error of data in a tape management area takes place due to a scratch on the tape, the management area data can be securely restored by the retry process.Assume that the initial value of the physical ID is equivalent to 4000ID that is the distance measured from the PBOT. After the normal write process for the VSIT is performed, the initial value of the physical ID becomes -1600ID (see FIG. 19A). After the first write retry process has been performed, the initial value of the physical ID becomes -1700ID (see FIG. 19B). After the first write retry process has been performed, the initial value of the physical ID becomes -1800ID (see FIG. 19C). Thus, whenever the retry process is performed, the initial value of the physical ID is decreased for 100ID. On the other hand, the VSIT is written from 0ID. In the retry process for the VSIT, the physical ID of the start position is not changed. However, the real write position (namely, the distance measured from the start position) is changed. Thus, even if the write data of the VSIT has an error due to for example a scratch on the tape, the write error of the VSIT can be recovered by the retry process.
摘要:
A method and apparatus for reproducing a plurality of main data recorded on an insertable recording medium in the desired sequence specified as a playlist by the user. Main data is recorded on a record region of the recording medium and the user can select a playlist that is recorded in a management region of the recording medium.
摘要:
A music piece distributing apparatus receives a request signal including music piece identification information and compressing system identification information from a receiving apparatus and transmits music piece data in which a music piece corresponding to the music piece identification information has been compressed by a compressing system corresponding to the compressing system identification information to the receiving apparatus. The request signal is transmitted through a public line. A music piece receiving apparatus receives the music piece data from the music piece distributing apparatus by a digital broadcasting receiving apparatus and decodes the received music piece data by a compression decoding system corresponding to the compressing system designated by the compressing system identification information.
