Provided is a display device comprising a plurality of display modules and a base module. The base module includes a transmitter configured to transmit a plurality of image signals respectively corresponding to each of the plurality of display modules. A first display module is coupled to the base module to receive the image signals and to transmit at least a subset of the image signals to additional display modules, such as a second display module which is coupled to the first display module to receive the at least a subset of the plurality of image signals from the first display module. The plurality of display modules may be thereby coupled with each other to thus receive and further transmit the image signals to and from other display modules, thereby improving convenience in the manufacture, inspection, and repair of the display device.

A communication apparatus includes an acquisition unit configured to acquire image capture information associated with a plurality of image capturing apparatuses, a generation unit configured to generate a playlist in which access information associated with a plurality of pieces of video data captured by the plurality of image capturing apparatuses and the image capture information acquired by the acquisition unit are described, and a transmission unit configured to transmit the playlist generated by the generation unit to another communication apparatus.
