Abstract

[Object] To reproduce a plurality of video contents recorded on a recording medium on one screen and select and reproduce any of the video contents without using a plurality of dedicated decoders.

[Solving Means] A recording/reproducing apparatus (100) reads single angle videos (21) that are shot from a plurality of angles and a multi-angle video (22) obtained by performing authoring on those single angle videos (21) so as to be reproducible on one screen from a BD-ROM (10), combines a time-line operation bar (61) and a cursor (66) with the multi-angle video (22), and displays a multi-angle screen (60). When an operation of selecting a single angle video (21) on which the cursor (66) is positioned is performed on the multi-angle screen (60), the single angle video (21) is reproduced in full screen based on a time code at a time when the selection operation is made. When an operation of pressing a multi-angle key (23) is performed during the full-screen reproduction, the multi-angle screen (60) is reproduced again based on a time code at a time when the press operation is made.

Claims

1. An electronic apparatus, comprising:

an input means for inputting a plurality of different first video contents each having the same first time code and a second video content having a second time code that is the same as the first time code, the second video content being edited so that the plurality of first video contents are simultaneously reproduced within one screen;

a reproduction means for reproducing the input first and second video contents;

an operation input means for inputting, from a user, a first operation of selecting any of the first video contents during reproduction of the second video content; and

a control means for controlling the reproduction means to, in a case where the first operation is input, reproduce the selected first video content based on the first time code corresponding to the second time code at a time when the first operation is input.

2. The electronic apparatus according to claim 1,

wherein the first and second video contents are recorded on a portable recording medium, and

wherein the input means includes means for reading each of the first and second video contents from the recording medium.

3. The electronic apparatus according to claim 2,

wherein the reproduction means includes one decoder that decodes the first and second video contents,

wherein the operation input means inputs, from the user, a second operation of instructing reproduction of the second video content during the reproduction of the first video content, and

wherein the control means controls the reproduction means to, in a case where the first operation is input, reproduce the first video content instead of the second video content based on the first time code corresponding to the second time code at the time when the first operation is input, and controls the reproduction means to, in a case where the second operation is input, reproduce the first video content instead of the second video content based on the second time code corresponding to the first time code at a time when the second operation is input.

4. The electronic apparatus according to claim 2,

wherein the reproduction means includes a first decoder that decodes the first video contents and a second decoder that reproduces the second video content, and

wherein the control means controls the reproduction means to reproduce the first video contents in a first area within the one screen and controls the reproduction means to reproduce the second video content in a second area that is different from the first area within the one screen.

5. The electronic apparatus according to claim 4,

wherein the control means controls the reproduction means to, in a case where the first operation is input, reproduce the selected first video content based on the first time code corresponding to a third time code obtained by adding a predetermined time to the second time code at the time when the first operation is input.

6. The electronic apparatus according to claim 5,

wherein the control means includes

means for judging whether the third time code and the second time code at a time when the selected first video content is reproduced are matched with each other, and

means for performing correction so that the third time code is matched with the second time code, in a case where it is judged by the comparison that the third time code and the second time code are not matched with each other.

7. The electronic apparatus according to claim 2, further comprising a storage means for storing reproduction history information of the plurality of first video contents that have been reproduced based on an input of the first operation,

wherein the control means includes a generation means for generating, based on the reproduction history information, a third video content in which the plurality of first video contents that have been reproduced are linked in a reproduction order, and

wherein the reproduction means reproduces the generated third video content.

8. The electronic apparatus according to claim 2,

wherein the reproduction means includes means for adding a predetermined video effect to the reproduced first video contents,

wherein the storage means stores the added predetermined video effect as a part of the reproduction history information of each of the first video contents, and

wherein the generation means generates the third video content by linking the first video contents with the stored predetermined video effects being added.

9. The electronic apparatus according to claim 2,

wherein the control means includes

means for controlling the reproduction means to display a time-line image that indicates a time line of the second video content and an icon that indicates a predetermined scene having the second time code predetermined on the time line, together with the reproduced second video content, and

means for controlling the reproduction means to move a reproduction point of the second video content to the predetermined scene based on the second time code corresponding to the icon in a case where an operation of selecting the icon is input by the operation input means from the user.

10. The electronic apparatus according to claim 9,

wherein the operation input means inputs, from the user, a third operation of designating any position on the displayed time-line image during the reproduction of the second video content, and

wherein the control means controls the reproduction means to display the icon at the designated any position on the displayed time-line image so that the icon can be selected in a case where the third operation is input,

the electronic apparatus further comprising a storage means for storing the second time code for reproducing the second video content from a scene corresponding to the any position at which the icon is displayed.

11. The electronic apparatus according to claim 2,

wherein the plurality of first video contents are respectively shot in different predetermined locations, and

wherein the second video content includes a predetermined map image including the predetermined locations and a plurality of areas that are arranged to respectively reproduce the plurality of first video contents at positions indicating the predetermined locations on the predetermined map image.

12. A reproduction method, comprising:

inputting a plurality of different first video contents each having the same first time code and a second video content having a second time code that is the same as the first time code, the second video content being edited so that the plurality of first video contents are simultaneously reproduced within one screen;

reproducing the second video content;

inputting, from a user, a first operation of selecting any of the first video contents during reproduction of the second video content; and

reproducing, in a case where the first operation is input, the selected first video content based on the first time code corresponding to the second time code at a time when the first operation is input.

13. A program to cause an electronic apparatus to execute:

a step of inputting a plurality of different first video contents each having the same first time code and a second video content having a second time code that is the same as the first time code, the second video content being edited so that the plurality of first video contents are simultaneously reproduced within one screen;

a step of reproducing the second video content;

a step of inputting, from a user, a first operation of selecting any of the first video contents during reproduction of the second video content; and

a step of reproducing, in a case where the first operation is input, the selected first video content based on the first time code corresponding to the second time code at a time when the first operation is input.
