Hybrid broadcasting and communication services are made excellently implementable. A transport stream obtained by time-division multiplexing a first transmission packet including a predetermined component and a second transmission packet including information on the predetermined component is generated. The transport stream is transmitted along a predetermined transmission path. Information on a plurality of distribution protocols, the information on each distribution protocol including at least location information and protocol identification information, for acquiring a specific component to be acquired on a communication path, or acquisition information for acquiring the information on the plurality of distribution protocols is inserted into the second transmission packet, in relation to the specific component. A receiving side can excellently receive the specific component through a distribution protocol in accordance with its own distribution network environment.

A wireless communication device and an image display apparatus including the same are disclosed. An image display according to an embodiment of the present disclosure comprises a display, a memory to store country code information, a signal processing device to output an image signal to the display, and a wireless communication device to perform wireless communication with an external device, wherein the wireless communication device is configured to scan a beacon frame, set wireless channel and wireless transmission power based on the country code information stored in the memory in response to a beacon frame being not received within a predetermined period, and in response to the beacon frame being received within the predetermined period, extract the country code information within the beacon frame and set wireless channel and wireless transmission power based on the extracted country code information. Accordingly, it is possible to efficiently perform wireless communication.
