1. 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, andwherein the change order number is a number associated with each of the feed change logs.

Abstract
A method and apparatus for synchronizing feed information are provided. A podcasting client includes a synchronization-processing unit which synchronizes first feed information acquired from a connected device with pre-stored second feed information, and a communication interface which transmits feed information of content that is podcast based on the synchronized feed information to the connected device.

1. 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A device comprising:
-
a feed-change-log-management unit which generates a first feed change log in which a change of first feed information is recorded; and a communication interface which receives from a podcasting client an anchor that includes resultant information of synchronization performed based on the first feed change log and a second feed change log in which a change of second feed information of the connected podcasting client is recorded, wherein the anchor includes at least one of a first change order number of a first feed change log processed during a previous synchronization 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 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. - View Dependent Claims (12)

13. A method of synchronizing feed information, the method comprising:
-
synchronizing, with second feed information, first feed information acquired from a connected device; and transmitting, to the connected device, feed information of content that is podcast based on the synchronized first feed information, wherein the synchronizing comprises performing 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 side coincides with a second anchor, and wherein the synchronizing comprises copying the second feed information to the connected device if the first anchor including resultant information of synchronization of the connected device does not coincide with the second anchor, 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. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of synchronizing feed information, the method comprising:
-
generating a first feed change log in which a change of first feed information is recorded; and storing an anchor that includes resultant information of synchronization performed based on the first feed change log and a second feed change log in which a change of second feed information of a connected podcasting client is recorded, wherein the anchor includes at least one of a first change order number of a first feed change log processed during a previous synchronization 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 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. - View Dependent Claims (21)
