Method and apparatus for reproducing content according to information embedded in the content
View Patent ↗In an apparatus that carries out reproduction control on the basis of digital watermark information embedded in a content, for the purpose of providing a reproducing apparatus and a reproducing method in which reproduction stoppage in the middle of reproduction according to the detection result of the digital watermark information does not occur, the reproducing apparatus and the reproducing method are configured so that before reproduction the detection section thereof detects attached information embedded in a content that is recorded on a recording medium, so that the content and the attached information that is detected using the detection section are stored in the storage section thereof so as to be related to each other, and so that the reproduction of the content corresponding to the attached information stored in the storage section is controlled according to the attached information.
1. A reproducing apparatus comprising:
a detection section that detects attached information embedded in a content recorded on a recording medium, and
a control section that controls the reproduction of the content corresponding to the attached information detected using said detection section according to the attached information, wherein
when a reproduction start command has been input, attached information detection operation for detecting the attached information is performed before reproducing operation without outputting sound to the outside of the reproducing apparatus, and reproduction control is carried out according to the result of the detection.
2. The reproducing apparatus according to claim 1 , wherein the detection result regarding the attached information detected using said detection section is recordable on said recording medium.
3. The reproducing apparatus according to claim 1 , wherein said detection section is formed of a digital watermark detection section.
4. The reproducing apparatus according to claim 1 , wherein the attached information is information embedded as a digital watermark in the content.
5. The reproducing apparatus according to claim 1 , wherein the detection of the attached information using said detection section is done more quickly than reproducing operation.
6. A reproducing apparatus comprising:
a detection section that detects attached information embedded in a content recorded on a recording medium before reproducing operation without outputting sound to the outside of the reproducing apparatus is carried out,
a storage section that stores the attached information detected using said detection section and the content so as to be related to each other using a method capable of preventing falsification or a method capable of detecting falsification, and
a control section that controls the reproduction of the content corresponding to the attached information stored in said storage section according to the attached information.
7. A reproducing apparatus comprising:
a detection section that detects attached information embedded in a content recorded on a recording medium before reproducing operation without outputting sound to the outside of the reproducing apparatus, when the attached information is in a detectable state,
a storage section that stores the detected attached information and the content so as to be related to each other using a method capable of preventing falsification or a method capable of detecting falsification, and
a control section that controls the reproduction of the content corresponding to the attached information stored in said storage section according to the attached information.
8. A reproducing method comprising:
a step of detecting attached information embedded in a content recorded on a recording medium before reproducing operation without outputting sound to the outside of the reproducing apparatus is carried out when a reproduction start command has been input, and
a step of controlling the reproduction of the content corresponding to the detected attached information according to the attached information.
9. The reproducing method according to claim 8 , wherein the detection result regarding the attached information of the content recorded on said recording medium is recorded on said recording medium.
10. The reproducing method according to claim 8 , wherein the detection of the attached information is done more quickly than reproducing operation.
11. A reproducing method comprising:
a step of detecting attached information embedded in a content recorded on a recording medium before reproducing operation without outputting sound to the outside of the reproducing apparatus is carried out,
a step of storing the detected attached information and the content so as to be related to each other using a method capable of preventing falsification or a method capable of detecting falsification, and
a step of controlling the reproduction of the content corresponding to the stored attached information according to the attached information.
12. A reproducing method comprising:
a step of detecting attached information embedded in a content without outputting sound to the outside of the reproducing apparatus when the attached information is in a detectable state, even before a reproduction start command is input,
a step of storing the detected attached information, and
a step of controlling the reproduction of the content corresponding to the stored attached information according to the attached information.
