Patent ID: 8909600

Claim:
An apparatus comprising: a holding memory configured to hold a communication parameter used to perform communication with a storage device configured to store content; a content data memory configured to store content; a change recording memory configured to store a record of change in the content stored in the content data memory; a transmitter configured to transmit the record of change to the storage device to synchronize content stored in the storage device with content stored in the content data memory; and a processor coupled to the holding memory, the content data memory, the change recording memory, and the transmitter, wherein the processor is programmed to function as: a determination unit configured to determine whether there is an instruction to delete a first communication parameter associated with a first storage device, wherein the first communication parameter associated with the first storage device is used to perform communication with the first storage device; a finding unit configured to find a first record of change associated with the first storage device, upon a determination by the determination unit that there is the instruction to delete the first communication parameter, wherein the first record of change, which indicates a change in the content stored in the content data memory, is used to synchronize content stored in the first storage device with the content stored in the content data memory; and a deletion unit configured to delete the first communication parameter from the holding memory and the first record of change from the change recording memory, upon the determination by the determination unit that there is the instruction to delete the first communication parameter.
