Abstract
Provided are a synchronization identifier generating method for synchronizing digital contents and an apparatus for the same. The synchronization identifier generating method includes setting a sampling level that indicates a frequency of sampling digital contents; sampling the digital contents on the basis of the set sampling level; generating a first message digest on the basis of data sampled during the sampling the digital contents; and generating a synchronization identifier including the set sampling level and the first message digest.
Claims23
A synchronization identifier generating method for synchronizing digital contents, the method comprising:
- setting a sampling level that indicates a frequency of sampling digital contents;
- sampling the digital contents on the basis of the set sampling level;
- generating a first message digest on the basis of data sampled during the sampling the digital contents;
- and
- generating a synchronization identifier including the set sampling level and the first message digest.
A synchronization identifier generating method for synchronizing digital contents, the method comprising:
- a first device recognizing a first digital content including a synchronization identifier generated by a second device;
- and
- adding the synchronization identifier to an existing synchronization identifier list in the first device, if the synchronization identifier is a duplicate of a synchronization identifier in the existing synchronization identifier list, on the basis of a determination result of determining whether or not the first digital content is identical to a second digital content corresponding to the duplicated synchronization identifier in the existing synchronization identifier list.
A synchronization identifier generating apparatus for synchronizing digital contents, the apparatus comprising:
- a sampling module which sets a sampling level that indicates a frequency of sampling digital contents and samples the digital contents on the basis of the set sampling level;
- a message digest generating module which generates a first message digest on the basis of data sampled during the sampling the digital contents;
- and
- a synchronization identifier generating module which generates a synchronization identifier that comprises the set sampling level and the first message digest.
A synchronization identifier generating apparatus for synchronizing digital contents, the apparatus comprising:
- a fixed device interface module which receives a first digital content including a synchronization identifier generated by another device;
- and
- a synchronization identifier management unit which adds the synchronization identifier to an existing synchronization identifier list, if the synchronization identifier is a duplicate of a synchronization identifier in the existing synchronization identifier list, on the basis of a determination result of determining whether or not the first digital content is identical to a second digital content corresponding to the duplicated synchronization identifier in the existing synchronization identifier list.
