Abstract

A recording medium playing apparatus allows an arbitrary and easy selection and reproduction of each information piece of a recording medium carrying a plurality of information pieces which variously represent a scene on the same time axis position during reproduction of information. In the recording medium playing apparatus for playing a recording medium on which same-time information groups each formed by a plurality of information pieces of the same time position are recorded, reproducing means for reproducing information of the recording medium reproduces information of the recording medium by arbitrarily selecting each information piece of the recording medium based on a command for reproducing each same-time information group.

Claims

1. A recording medium playing apparatus for playing a recording medium on which at least a same-time information group formed by a plurality of information pieces of a same time position is recorded, each of said plurality of information pieces representing an image of a scene viewed at a different viewing angle, comprising:

reproducing means for reproducing information recorded on said recording medium;

selecting means for randomly selecting a single information piece without user intervention from among the plurality of information pieces of said same-time information group, each information piece representing an image of a different viewing angle; and

control means for controlling said reproducing means to reproduce an information piece selected by said selecting means when reproducing said same-time information group.

2. A recording medium playing apparatus as claimed in any one of claims 1 through 7, further comprising:

memory means for storing specifying data for specifying a selected information piece of said same-time information group, said memory means storing an identification information piece recorded on said recording medium and said specifying data in the form of a pair; and

a comparing means for comparing an identification information piece retrieved from said recording medium with said identification information piece stored in said memory means,

wherein said control means controls said reproducing means to reproduce information of said recording medium based on said specifying data stored in a pair including said identification information when a coincidence between said identification information pieces is detected by said comparing means.

3. An recording medium playing apparatus as claimed in claim 1, further comprising detection means for detecting said same-time information group, wherein said control means controls said reproducing means to reproduce said information piece selected by said selecting means when said same-time information group is detected by said detection means.

4. A recording medium playing apparatus as claimed in claim 3, further comprising setting means for setting an order of reproduction of information pieces recorded on said recording medium, said setting means is operative to set said information piece selected by said selecting means as an information piece to be reproduced in said same-time information group.

5. A recording medium playing apparatus as claimed in claim 1, wherein information recorded on said recording medium is image information, and information pieces included in said same-time information group are image information pieces obtained by shooting or representing a same object at a plurality of angles.

6. A recording medium playing apparatus as claimed in claim 3, wherein information recorded on said recording medium is image information, and information pieces included in said same-time information group are image information pieces obtained by shooting or representing a same object at a plurality of angles.

7. A recording medium playing apparatus as claimed in claim 4, wherein information recorded on said recording medium is image information, and information pieces included in said same-time information group are image information pieces obtained by shooting or representing a same object at a plurality of angles.

9. The recording medium playing apparatus for playing a recording medium of claims 1 or 8, wherein the recording medium stores at least a same-time information group formed by a plurality of information pieces of a same time position, and stores specifying data for specifying a selected information piece for each of said same-time information group.

8. A recording medium playing apparatus for playing a recording medium on which same-time information groups each formed by a plurality of information pieces of a same time position are recorded, comprising:

reproducing means for reproducing information recorded on said recording medium;

input means for entering an all-cells command for reproducing all of the information pieces included in each of said same-time information groups; and

control means for controlling said reproducing means to reproduce, when reproducing the same-time information groups, a single information piece included in each of said same-time information groups if said all-cells command has not been entered, and to reproduce, when reproducing the same-time information groups, all of the information pieces included in each of said same-time information groups without further command entry if said all-cells command has been entered.
