Abstract
A method of using a series of data DT by a data processor is provided. The data are recorded over plural sections that can be managed on a recording medium. The method includes the steps of storing plural kinds of link information LA, LB for designating one or more sections of the data DT that enables the use in the recording medium ST in accordance with license levels, and enabling the use of the link information LA or LB corresponding to the license level that was selected by a user.
Claims19
A method of using a series of data by a data processor, the data being recorded over plural sections that can be managed on a recording medium, the method comprising the steps of:
- storing plural kinds of link information for designating one or more sections of the data that enables the use in the recording medium in accordance with license levels;
- and
- enabling the use of the link information corresponding to the license level that was selected by a user.
A method of using a series of data by a data processor, the data being recorded over plural sections that can be managed on a recording medium, the method comprising the steps of:
- storing plural kinds of link information for designating one or more sections of the data that enables the use in the recording medium in accordance with license levels;
- enabling the use of the link information corresponding to the license level that was selected by a user;
- and
- enabling a provider of the data to do a charging process in accordance with the license level.
A method of using a series of data by a data processor, the data being scrambled by a first cryptographic key and recorded over plural sections that can be managed on a recording medium, the method comprising the steps of:
- storing plural kinds of link information for designating one or more sections of the data that enables the use in the recording medium in accordance with license levels;
- performing a charging process to a user in accordance with the license level selected by the user;
- permitting the user to get the first cryptographic key so that the data processor can decode the data;
- and
- outputting the contents of the data from the data processor using the link information corresponding to the selected license level.
A data processor for using a series of data recorded over plural sections that can be managed on a recording medium, the data processor comprising:
- link information storage means for storing the link information for designating one or more sections of the data that enables the use;
- selection input means for selecting a license level;
- and
- means for outputting the contents of the data using the link information corresponding to the selected license level.
A recording medium on which a series of data is recorded over plural sections that can be managed so that the data processor can use the data, wherein the recording medium stores plural kinds of link information for designating one or more sections of the data that enables the use, in accordance with license levels.
A computer usable medium, on which a series of data is recorded over plural sections that can be managed so that the data processor can use the data, wherein the computer usable medium stores plural kinds of link information for designating one or more sections of the data that enables the use in accordance with license levels, a display control program for displaying a selection input picture used for selecting a license level, and an output processing program for outputting the contents of the data using the link information corresponding to the selected license level.
