Patent ID: 8539037

Claim:
A podcasting client comprising: a synchronization-processing unit which synchronizes first feed information acquired from a connected device with second feed information; and a communication interface which transmits feed information of content that is podcast based on the synchronized first feed information to the connected device, wherein the synchronization-processing unit performs synchronization based on the first feed information and the second feed information if a first anchor including resultant information of synchronization of the connected device coincides with a second anchor including resultant information of synchronization of the podcasting client, wherein the synchronization-processing unit copies the second feed information into the connected device if the first anchor including resultant information of synchronization of the connected device does not coincide with the second anchor including resultant information of synchronization of the podcasting client, wherein the first anchor and the second anchor include at least one of a first change order number of a first feed change log processed during a previous synchronization with the connected device among first feed change logs included in the first feed information and a second change order number of a second feed change log processed during the previous synchronization with the connected device among second feed change logs included in the second feed information, wherein the first and the second feed change logs record changes generated in a feed database in which the feed information is stored, and wherein the change order number is a number associated with each of the feed change logs.
