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. ## Claims ### Claim 1 A method for providing contents, comprising the steps of: reproducing at least one content, at a device; transmitting the at least one content from the device to a display device to reproduce, in the display device, the transmitted at least one content; receiving a message from a mobile device during the reproducing of the at least one content at the device; providing the received message while reproducing the at least one content at the device; and transmitting, from the device, the received message to the display device, the transmitted message being used to enable the display device to provide the transmitted message while reproducing the at least one content. ### Claim 2 (depends on 1) The method of claim 1, further comprising: when a manipulation command is inputted at the device, reproducing, at the device, the content according to the inputted manipulation command; and transmitting, from the device, the manipulation command to the display device so that the display device reproduces according to the manipulation command. ### Claim 3 (depends on 1) The method of claim 1, further comprising: when a command to delete the content is inputted at the device, transmitting, from the device, the command to delete to the display device so that the display device deletes the content according to the command to delete. ### Claim 4 (depends on 3) The method of claim 3, further comprising, when the command to delete the content is inputted at the device, deleting the content according to the inputted command to delete at the device. ### Claim 5 (depends on 1) The method of claim 1, wherein, when the device and the display device are electronic frames, the content comprises photo content or video content reproduced on the device and the display device. ### Claim 6 (depends on 1) The method of claim 1, wherein, when the device and the display device are electronic books, the content comprises text content reproduced on the device and the display device. ### Claim 7 (depends on 1) The method of claim 1, wherein, when the device and the display device are Large Format Displays (LFDs), the content comprises advertisement content reproduced on the device and the display device. ### Claim 8 A device, comprising: a memory for storing at least one content; a communication unit for communicating with a display device; a processor for reproducing the at least one content, transmitting the at least one content to the display device to reproduce the transmitted at least one content, receiving a message from a mobile device during the reproducing of the at least one content at the device, providing the received message while reproducing the at least one content and transmitting the received message to the display device, the transmitted message being used to enable the display device to provide the transmitted message together while reproducing the at least one content. ### Claim 9 A system comprising a device and a display device, the system comprising: the device that reproduces at least one content, transmits the at least one content to the display device, provides a message while reproducing the at least one content at the device when the message is received from a mobile device during the reproducing of the at least one content at the device, and transmits the received message to the display device; and the display device that receives the at least one content from the device, reproduces the at least one content, receives the message from the device, and provides the message while reproducing the at least one content. ### Claim 10 (depends on 8) The device of claim 8, wherein when a manipulation command is inputted, the processor reproduces the content according to the inputted manipulation command and transmits the manipulation command to the display device so that the display device reproduces according to the manipulation command. ### Claim 11 (depends on 8) The device of claim 8, wherein when a command to delete the content is inputted, the processor transmits the command to delete to the display device so that the display device deletes the content according to the command to delete. ### Claim 12 (depends on 11) The device of claim 11, wherein when the command to delete the content is inputted, the processor deletes the content according to the inputted command to delete.
