Abstract: According to one embodiment, a content providing system of a terminal in a content providing system, a content server is requested to provide specific content. The specific content and a reward item associated with the specific content are received from the content server. A reward item list representing reward items associated with content having content providers different from each other is generated. The reward item list is displayed. Multiple content are received from a plurality of content providers. A corresponding reward item is determined for each received content. A specific content provide request is received from the terminal. The requested content and a reward item corresponding to the requested content are then transmitted to the terminal.

Abstract: A method, devices, and a non-transitory recording medium for providing contents are provided. The method includes reproducing at least one content, at a first device; transmitting information corresponding to the at least one content from the first device to a second device to reproduce content corresponding to the at least one content in the second device; receiving a message from an external device while reproducing the at least one content at the first device; providing the received message while reproducing the at least one content at the first device; and transmitting information corresponding to the received message from the first device to the second device, the information corresponding to the received message being used to enable the second device to provide a message corresponding to the received message while reproducing the content corresponding to the at least one content.

Abstract: Methods and apparatuses are provided for providing contents. A plurality of contents is reproduced at the first device. The plurality of contents is transmitted from the first device to a second device to reproduce, in the second device, content in synchronization with the first device. Data is received from an external device during the reproducing of the plurality of contents at the first device. The received data is reproduced along with at least one of the plurality of contents being reproduced at the first device. The received data is transmitted from the first device to the second device. The transmitted data is used to enable the second device to reproduce the transmitted data together with the at least one of the plurality of contents.
