a storage configured to store a list of a first content group designated to allow sharing by a first user of the first external device, a second content group designed to block sharing by the first user, a third content group designated to allow sharing by a second user of the second external device, and a fourth content group designated to block sharing by the second user; and a processor configured to: selectively process a content list based on detection of the first external device and detection of the second external device through the communication circuit. ## Claims ### Claim 1 A display apparatus comprising: a display configured to rotate; a communication circuit configured to communicate with an external device; a processor configured to: in response to receiving an instruction for displaying a content, identify a position where the display rotates, corresponding to a characteristic of the content, in response to identifying that the external device is detected through the communication circuit, identify whether the detected external device corresponds to the content, based on identifying that the detected external device corresponds to the content, cause the display to rotate to the identified position and display an image of the content on the display, and based on identifying that the detected external device does not correspond to the content, prevent rotation of the display to the identified position and prevent display of the image of the content on the display. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to identify the position of the display where a ratio of a horizontal length and a vertical length of the display matches the image. ### Claim 3 (depends on 2) The display apparatus according to claim 2, wherein the processor is configured to cause the display to rotate to a first position based on identifying that the image is a landscape image, and the display in the first position is in a state that the horizontal length is longer than the vertical length. ### Claim 4 (depends on 2) The display apparatus according to claim 2, wherein the processor is configured to cause the display to rotate to a second position based on identifying that the image is a portrait image, and the display in the second position is in a state that the vertical length is longer than the horizontal length. ### Claim 5 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to obtain the characteristic of the content from metadata of the content. ### Claim 6 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to obtain identification information of the content, and identify that the detected external device corresponds to the content, based on the detected external device corresponding to the identification information of the content. ### Claim 7 (depends on 1) The display apparatus according to claim 1, further comprising a user input section, wherein the processor is configured to receive the instruction from a user through the user input section. ### Claim 8 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to prevent to rotation of the display to the identified position and prevent display of the image of the content on the display, based on identifying that any external device is not detected. ### Claim 9 (depends on 1) The display apparatus according to claim 1, wherein the communication circuit complies with Institute of Electrical and Electronics Engineers (IEEE) 802.15 standards. ### Claim 10 A method of controlling a display apparatus, the method comprising: in response to receiving an instruction for displaying a content, identifying a position where a display rotates, corresponding to a characteristic of the content; in response to identifying that an external device is detected through a communication circuit, identifying whether the detected external device corresponds to the content; based on identifying that the detected external device corresponds to the content, causing the display to rotate to the identified position and displaying an image of the content on the display; and based on identifying that the detected external device does not correspond to the content, preventing rotation of the display to the identified position and preventing display of the image of the content on the display. ### Claim 11 (depends on 10) The method of the display apparatus according to claim 10, further comprising: identifying the position of the display where a ratio of a horizontal length and a vertical length of the display matches the image. ### Claim 12 (depends on 11) The method of the display apparatus according to claim 11, further comprising: rotating the display to a first position based on identifying that the image is a landscape image, wherein the display in the first position is in a state that the horizontal length is longer than the vertical length. ### Claim 13 (depends on 11) The method of the display apparatus according to claim 11, further comprising: rotating the display to a second position based on identifying that the image is a portrait image, wherein the display in the second position is in a state that the vertical length is longer than the horizontal length. ### Claim 14 (depends on 10) The method according to claim 10, further comprising: obtaining the characteristic of the content from metadata of the content. ### Claim 15 (depends on 10) The method according to claim 10, further comprising: obtaining identification information of the content, and identifying that the detected external device corresponds to the content, based on the detected external device corresponding to the identification information of the content. ### Claim 16 (depends on 10) The method of the display apparatus according to claim 10, further comprising: receiving the instruction from a user through a user input section. ### Claim 17 (depends on 10) The method of the display apparatus according to claim 10, further comprising: preventing rotation of the display to the identified position and preventing display of the image of the content on the display, based on identifying that any external device is not detected. ### Claim 18 (depends on 10) The method of the display apparatus according to claim 10, wherein the communication circuit complies with IEEE 802.15 standards. ### Claim 19 A display apparatus comprising: a display configured to rotate; a communication circuit configured to communicate with an external device; a processor configured to: in response to receiving an instruction to rotate the display, obtain identification information of an external device and identify whether the external device indicated by the identification information is detected through the communication circuit, based on identifying that the external device indicated by the identification information is detected, cause the display to rotate according to the instruction, and based on identifying that the external device indicated by the identification information is not detected, prevent rotation of the display.
