When the component information indicates that the received digital contents are a 3D component, it is determined whether a display part corresponds to display of the 3D component. If the display part corresponds to display of the 3D component, the received digital contents are displayed in 3D. ## Claims ### Claim 1 A display apparatus comprising: an interface circuitry configured to receive video content and content information including information which identifies whether or not video content is 3D video content; a video processor configured to conduct video processing of video content; an operation instruction receiver configured to receive an operation instruction by the viewer; a display configured to display video content in 3D view or in 2D view; and a processor, wherein in a case where the content information received via the interface circuitry indicates that the video content to be received is 3D video content, the processor is configured to: cause the display to display an indication that 3D video content is identified; and cause the display to display a selection indication for requesting a viewer to input an operation instruction via the operation instruction receiver to select whether to allow viewing the video content in 3D view or to not allow viewing the video content in 3D view, and wherein in a case where the content information received via the interface circuitry indicates that the video content to be received is not 3D video content, the processor is configured to cause the display to not display an indication for requesting a viewer to input an operation instruction via the operation instruction receiver to select whether to view the video content in 3D view or to not view the video content in 3D view. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to control the video processor to conduct 3D video processing of the video content in a case where the operation instruction via the operation instruction receiver to allow viewing the video content in 3D view is input while the selection indication is displayed on the display. ### Claim 3 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to control the video processor to conduct 2D video processing of the video content in a case where the operation instruction via the operation instruction receiver to not allow viewing the video content in 3D view is input while the selection indication is displayed on the display. ### Claim 4 (depends on 1) The display apparatus according to claim 1, wherein the processor is configured to control the video processor to conduct 2D video processing of the video content in a case where the operation instruction via the operation instruction receiver to erase the selection indication is input without performing a selection operation to the selection indication while the selection indication is displayed on the display. ### Claim 5 (depends on 1) The display apparatus according to claim 1, wherein the content information further comprises information which identifies a 3D method of the video content to be transmitted, and wherein the processor is configured to control the video processor to conduct 3D video processing of the video content if the display apparatus supports a 3D method indicated by the content information. ### Claim 6 (depends on 1) The display apparatus according to claim 1, wherein the content information further comprises information which identifies a 3D method of the video content to be transmitted, and wherein the processor is configured to control the video processor to conduct 2D video processing of the video content if the display apparatus does not support a 3D method indicated by the content information. ### Claim 7 (depends on 1) The display apparatus according to claim 1, wherein it is necessary to wear glasses for viewing a video content in 3D view in order for the viewer to view the video content in 3D view in a case where viewing the video content in 3D view is allowed by the operation instruction. ### Claim 8 A display apparatus comprising: an interface circuitry configured to receive video content and content information including information which identifies whether or not video content is 3D video content; a video processor configured to conduct video processing of video content; an operation instruction receiver configured to receive an operation instruction by the viewer; a display configured to display video content in 3D view or in 2D view; and a processor, wherein in a case where the content information received via the interface circuitry indicates that the video content to be received is 3D video content, the processor is configured to: cause the display to display an indication that 3D video content is identified; cause the display to display a selection indication for requesting a viewer to input an operation instruction via the operation instruction receiver to select whether to allow viewing the video content in 3D view or to not allow viewing the video content in 3D view; control the video processor to conduct 3D video processing of the video content in a case where the operation instruction via the operation instruction receiver to allow viewing the video content in 3D view is input while the selection indication is displayed on the display; and control the video processor to conduct 2D video processing of the video content in a case where the operation instruction via the operation instruction receiver to not allow viewing the video content in 3D view is input while the selection indication is displayed on the display, and wherein it is necessary to wear glasses for viewing a video content in 3D view in order for the viewer to view the video content in 3D view in a case where viewing the video content in 3D view is allowed by the operation instruction. ### Claim 9 (depends on 8) The display apparatus according to claim 8, wherein in a case where the content information received via the interface circuitry indicates that the video content to be received is not 3D video content, the processor is configured to cause the display to not display an indication for requesting a viewer to input an operation instruction via the operation instruction receiver to select whether to view the video content in 3D view or to not view the video content in 3D view. ### Claim 10 (depends on 8) The display apparatus according to claim 8, wherein the processor is configured to control the video processor to conduct 2D video processing of the video content in a case where the operation instruction via the operation instruction receiver to erase the selection indication is input without performing a selection operation to the selection indication while the selection indication is displayed on the display. ### Claim 11 (depends on 8) The display apparatus according to claim 8, wherein the content information further comprises information which identifies a 3D method of the video content to be transmitted, and wherein the processor is configured to control the video processor to conduct 3D video processing of the video content if the display apparatus supports a 3D method indicated by the content information. ### Claim 12 (depends on 8) The display apparatus according to claim 8, wherein the content information further comprises information which identifies a 3D method of the video content to be transmitted, and wherein the processor is configured to control the video processor to conduct 2D video processing of the video content if the display apparatus does not support a 3D method indicated by the content information.
