Abstract
Information data include audio information data corresponding to M (M: a natural number) types of audio information arbitrarily selected from N (N: a natural number not less than 3, and M.ltoreq.N) types of audio information set in advance. An apparatus for recording the information data onto a record medium as groups of audio information data corresponding to the selected M types respectively, is provided with: a data generating device for generating record content information data to identify the selected M types of audio information; and a recording unit for recording the generated record content information data and the groups of audio information data corresponding to the generated record content information data onto the record medium.
Claims11
An apparatus for recording onto a recording medium groups of audio information data, the audio information data corresponding to M (M:
- a natural number) kinds of audio information arbitrarily selected from N (N:
- a natural number not less than 3, and M.ltoreq.N) kinds of audio information, said apparatus comprising:
- a data generating device for generating record content information data identifying the selected M kinds of audio information;
- and
- recording means for recording on the recording medium the generated record content information data and the groups of audio information data.
An apparatus for reproducing information data in the form of an arbitrary combination of M (M:
- a natural number) kinds of audio information from a recording medium, the information data comprising (i) audio information data corresponding to the M kinds of audio information arbitrarily selected from N (N:
- a natural number not less than 3, and M.ltoreq.N) kinds of audio information, the audio information data being recorded as groups of audio information data corresponding to the selected M kinds respectively, and (ii) record content information data identifying the selected M kinds of audio information the apparatus comprising:
- reading means for reading the groups of audio information data and the record content information data from the recording medium;
- identifying means for identifying on the basis of the record content information data read by the reading means the M kinds of audio information corresponding to the groups of audio information data read by the reading means;
- instructing means for selecting a combination of the M kinds of audio information to be reproduced;
- and
- signal processing means for extracting the audio information data corresponding to the selected combination to be reproduced, and reproducing the extracted audio information data.
An apparatus for reproducing from a recording medium information data in a form of an arbitrary combination of M.sub.1, . . . , M.sub.L (M.sub.1, . . . , M.sub.L :
- a natural number, L:
- a natural number) kinds of audio information, the information data comprising (i) audio information data corresponding to the M.sub.1, . . . , M.sub.L kinds of audio information each arbitrarily selected from N (N:
- a natural number not less than 3, and M.sub.1, . . . , M.sub.L .ltoreq.N) kinds of audio information, each recorded as groups of audio information data corresponding to the selected M.sub.1, . . . , M.sub.L kinds respectively, and (ii) L pieces of record content information data to respectively identify the selected M.sub.1, . . . , M.sub.L kinds of audio information, the apparatus comprising:
- first instructing means for selecting the group of audio information data to be reproduced;
- reading means for reading from the recording medium the selected group of audio information data and the record content information data corresponding to the selected group of audio information data;
- identifying means for identifying the audio information constituting the group of audio information data read by said reading means on the basis of the record content information data read by said reading means;
- second instructing means for selecting a combination of the M.sub.1, . . . , M.sub.L kinds of audio information constituting the group of audio information data to be reproduced;
- and
- signal processing means for extracting from the group of audio information data read by said reading means the audio information data corresponding to the selected combination to be reproduced, and reproducing the extracted audio information data.
