Patent ID: 8776156

Claim:
A content receiving apparatus comprising: a first receiver configured to receive a first identifier of a first content and a replaying position data regarding a replaying position of the first content from a first external apparatus, the first identifier used for accessing the first content; a modification rule database stored with one or more modification rules; a transmission controller configured to generate a second identifier of a second content by changing a portion of the first identifier based on one or more modification rules within the modification rule database if the first identifier includes a specific identifier, the second content corresponding to the first content and a quality of the second content being different from a quality of the first content; a transmitter configured to transmit a content request by using the second identifier to a second external apparatus different from the first external apparatus; a second receiver configured to receive data of the second content transmitted from the second external apparatus in response to the content request; and a processor configured to replay the second content, wherein if the first identifier does not include the specific identifier, the transmission controller is configured not to generate the second identifier based on the one or more modification rules, the transmitter is configured to transmit the content requested by using the first identifier, and the second receiver is configured to receive the first content, wherein the processor is configured to replay the first content from a first replaying position indicated by the replaying position data, and wherein the processor is configured to replay the second content from a second replaying position determined by using the replaying position data.
