Contents distribution system with integrated recording rights control
First Claim
1. A recipient apparatus for acquiring a content from a distributing apparatus, comprising:
- a first storage section that comprises a non-volatile memory and buffers pieces of the content distributed from the distributing apparatus by a streaming technique for a preview;
a reproduction section that successively reproduces to an output device the piece of the content being buffered to said first storage section;
a saving request generation section that generates, during the reproduction of the content distributed by the streaming technique for the preview, a saving request for permission to save the whole of the content; and
a non-volatile second storage section that saves, in the case where the saving request is generated during the reproduction of the content for the preview, a first partial content of the content as first saving data, the first partial content being distributed from the distributing apparatus by a streaming technique and successively reproduced by said reproduction section after the saving request is generated,wherein, in the case where the saving request is generated during the reproduction of the content for the preview, the non-volatile second storage section further saves a second partial content of the content as second saving data, the second partial content being distributed from the distributing apparatus by a downloading technique according to the saving request and corresponding to the pieces of content distributed from the distributing apparatus by the streaming technique and reproduced for the preview by said reproduction section before the saving request is generated, andwherein, in the case where the saving request is generated during the reproduction of the content for the preview, the first saving data and the second saving data are saved in the non-volatile second storage section to acquire the whole of the content.

Abstract
A content distribution system that includes a distributing apparatus that stores content which is distributable to a recipient apparatus. At least some of the content which is designated by the recipient apparatus is distributed by a streaming technique. During distribution of the content by the streaming technique, in response to a saving request from the recipient apparatus, the distributing apparatus generates and transmits a saving permission signal for notifying the recipient apparatus that saving of the content is permitted. As a result, the received content is saved in the recipient apparatus. After the distribution of the content by the streaming technique is completed, the distributing apparatus distributes difference data, which is a portion of the content that has not been saved in the recipient apparatus, by downloading technique.

4. An acquisition method for acquiring a content from a distributing apparatus, comprising:
-
a first storage step of buffering to a first storage device pieces of the content distributed from the distributing apparatus by a streaming technique for a preview; a reproduction step of successively reproducing the pieces of the content buffered in said first storage step; a saving request generation step of generating, during the reproduction of the content distributed by the streaming technique for the preview, a saving request for permission to save the whole of the content; and a second storage step of, in the case where the saving request is generated during the reproduction of the content for the preview, saving to a non-volatile second storage device a first partial content of the content, the first partial content being distributed from the distributing apparatus by a streaming technique and successively reproduced by said reproduction step after the saving request is generated, wherein, in the case where the saving request is generated during the reproduction of the content for the preview, said second storage step further comprises saving a second partial content of the content, the second partial content being distributed from the distributing apparatus by a downloading technique according to the saving request and corresponding to the pieces of content distributed from the distributing apparatus by the streaming technique and reproduced for the preview by said reproduction step before the saving request is generated, and wherein, in the case where the saving request is generated during the reproduction of the content for the preview, the first saving data and the second saving data are saved in the non-volatile second storage device to acquire the whole of the content.

5. A computer program encoded on a computer-readable recording medium and including executable instructions, which when executed perform steps for enabling a recipient apparatus to acquire a content from a distributing apparatus, comprising:
-
a first storage step of buffering to a first storage device the pieces of content distributed from the distributing apparatus by a streaming technique for a preview; a reproduction step of successively reproducing the pieces of the content buffered in said first storage step; a saving request generation step of generating, during the reproduction of the content distributed by the streaming technique for the preview, a saving request for permission to save the whole of the content; and a second storage step of, in the case where the saving request is generated during the reproduction of the content for the preview, saving to a non-volatile second storage device a first partial content of the content, the first partial content being distributed from the distributing apparatus by a streaming technique and successively reproduced by said reproduction step after the saving request is generated, wherein, in the case where the saving request is generated during the reproduction of the content for the preview, said second storage step further comprises saving a second partial content of the content, the second partial content being distributed from the distributing apparatus by a downloading technique according to the saving request and corresponding to the pieces of content distributed from the distributing apparatus by the streaming technique and reproduced for the preview by said reproduction step before the saving request is generated, and wherein, in the case where the saving request is generated during the reproduction of the content for the preview, the first saving data and the second saving data are saved in the non-volatile second storage device to acquire the whole of the content.
