Abstract

According to one exemplary embodiment, a content receiving apparatus includes: a first receiver which receives a first identifier of first content from a first external apparatus; a generator which employs the first identifier to generate a second identifier of second content that corresponds to the first content but has different quality from the first content; a transmitter which transmits a content request including the second identifier to a second external apparatus different from the first external apparatus; and a second receiver which receives data of the second content transmitted from the second external apparatus in response to the content request.

Claims

1. 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.

2. The content receiving apparatus of claim 1, wherein the second content comprises a different video resolution level than the first content so that the second content has the different quality from the first content.

3. The content receiving apparatus of claim 1, wherein the second content comprises a different audio bitrate than the first content so that the second content has the different quality from the first content.

4. A data processing apparatus comprising:

a first processor configured to select a first content in content data stored on a first external apparatus;

a modification rule database stored with one or more modification rules;

a transmission controller configured to generate a second identifier of second content by replacing a portion of the first identifier according to one or more modification rules of 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 than a quality of the first content;

an identifier transmitter configured to transmit the second identifier to a second external apparatus different from the first external apparatus; and

a second processor configured to replay a content transmitted from the second external apparatus, 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 request by using the first identifier, and the second receiver is configured to receive the first content,

wherein the second processor is configured to replay the first content from a first replaying position indicated by the replaying position data, and

wherein the second processor is configured to replay the second content from a second replaying position determined by using the replaying position data.

5. A content receiving apparatus comprising:

a first receiver configured to receive a first identifier of 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 that comprises one or more modification rules;

a transmission controller configured to generate a second identifier of second content by changing a portion of the first identifier according to one or more modification rules of the modification rule database if the first identifier includes a specific identifier, the second content corresponds to the first content and differing in quality from 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 according to 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.

6. The content receiving apparatus of claim 5, wherein the second content comprises a different video resolution level than the first content so that the second content has the different quality from the first content.

7. The content receiving apparatus of claim 5, wherein the second content comprises a different audio bitrate than the first content so that the second content has the different quality from the first content.
