SERVER APPARATUS AND METHOD OF AQUIRING CONTENTS
First Claim
1. A server apparatus that stores a content acquired from a client device in a storage unit, said server apparatus comprising:
- a content segment acquisition unit configured to sequentially acquire, from the client device, comparison counterpart segments constituting a part of a candidate content, the comparison counterpart segments respectively corresponding to one of a plurality of comparison segments constituting a part of one or more already acquired contents stored in the storage unit;
a duplication decision unit configured to compare, each time said content segment acquisition unit acquires the comparison counterpart segment, the comparison counterpart segment and the comparison segment corresponding to the comparison counterpart segment, to thereby decide whether a content including the comparison segment that agrees with the comparison counterpart segment is present among the already acquired contents; and
a content acquisition unit configured to acquire the candidate content from the client device and store the candidate content in the storage unit in the case where said duplication decision unit decides that a content including the comparison segment that agrees with the comparison counterpart segment is not present among the already acquired contents,wherein said content segment acquisition unit is configured to abort acquisition of a subsequent comparison counterpart segment of the candidate content, in the case where said duplication decision unit decides that a content including the comparison segment that agrees with the comparison counterpart segment is not present among the already acquired contents.

Abstract
A server apparatus (200) includes a content segment acquisition unit (202) that sequentially acquires, from a client device (300), comparison counterpart segments constituting a part of a candidate content, each corresponding to each of comparison segments constituting a part of acquired contents, a duplication decision unit (204) that compares, each time the comparison counterpart segment is acquired, the comparison counterpart segment and the corresponding comparison segment to thereby decide whether a content having the comparison segment that agrees with the comparison counterpart segment is included in the acquired contents, and a content acquisition unit (208) that acquires the candidate content from the client device and stores the candidate content in the storage unit (211) in the case where such a content is not included. The content segment acquisition unit (202) aborts acquisition of a subsequent comparison counterpart segment in the case where the above content is not included.

15. A method of acquiring a content from a client device for storing the content in a storage unit, said method comprising:
-
sequentially acquiring, from the client device, comparison counterpart segments constituting a part of a candidate content, the comparison counterpart segments respectively corresponding to one of a plurality of comparison segments constituting a part of one or more already acquired contents stored in the storage unit; comparing the comparison counterpart segment and the comparison segment corresponding to the comparison counterpart segment each time the comparison counterpart segment is acquired in said acquiring of comparison counterpart segments, thereby deciding whether a content including the comparison segment that agrees with the comparison counterpart segment is present among the already acquired contents; and acquiring the candidate content from the client device and storing the candidate content in the storage unit in the case where it is decided that the content including the comparison segment that agrees with the comparison counterpart segment is not present among the already acquired contents, wherein said acquiring of comparison counterpart segments further includes aborting acquisition of a subsequent comparison counterpart segment of the candidate content, in the case where it is decided that the content including the comparison segment that agrees with the comparison counterpart segment is not present among the already acquired contents. - View Dependent Claims (16)
