Abstract

A wireless terminal may include: a communication unit that transmits/receives information; a recognition unit that recognizes whether a wireless terminal having transmitted the information is an opposite attribute wireless terminal based on the information received in the communication unit, when a wireless terminal having an attribute opposite to an attribute of its own terminal between the video transmission attribute and the video reception attribute is defined as the opposite attribute wireless terminal and a wireless terminal having the instruction attribute is defined as an instruction attribute wireless terminal; and a communication control unit that controls the communication unit to transmit information on a wireless terminal recognized as the opposite attribute wireless terminal to the instruction attribute wireless terminal when the recognition unit recognizes that the wireless terminal having transmitted the information is the opposite attribute wireless terminal.

wherein the communication control unit controls the communication unit to perform a process of establishing a wireless connection with the opposite attribute wireless terminal designated by wirelessly received information when the communication unit wirelessly receives, from the instruction attribute wireless terminal, the information for instructing video transmission and designating the opposite attribute wireless terminal that is a connection destination, and

wherein the instruction attribute wireless terminal is defined as a wireless terminal that has the instruction attribute, the instruction attribute wireless terminal being different from either the own terminal or the connectable wireless terminal.

2. The wireless terminal according to claim 1, wherein, in a state in which communication with the opposite attribute wireless terminal has been established, the communication control unit further controls the communication unit to transmit the identification information on the connectable wireless terminal recognized as the opposite attribute wireless terminal to the instruction attribute wireless terminal.

3. A wireless system, which includes a plurality of wireless terminals having only a video transmission attribute and a plurality of wireless terminals having only a video reception attribute, the video transmission attribute being defined as an attribute for wirelessly transmitting a video, the video reception attribute being defined as an attribute for wirelessly receiving and displaying the video, and an instruction attribute being defined as an attribute for instructing at least one of a plurality of wireless terminals having only the video transmission attribute to establish transmission of the video, wherein a wireless terminal having only the video transmission attribute or only the video reception attribute comprises:

a first communication unit that transmits/receives information;

a first communication control unit that controls the wireless terminal to search for a connectable wireless terminal; and

a recognition unit that recognizes whether the connectable wireless terminal is an opposite attribute wireless terminal based on identification information wirelessly received from the connectable wireless terminal, wherein a wireless terminal having an attribute opposite to an attribute of its own terminal between the video transmission attribute and the video reception attribute is defined as the opposite attribute wireless terminal,

wherein the first communication control unit controls the first communication unit to wirelessly transmit the identification information on the connectable wireless terminal recognized as the opposite attribute wireless terminal to an instruction attribute wireless terminal when the recognition unit recognizes that the connectable wireless terminal is the opposite attribute wireless terminal,

wherein the first communication control unit controls the first communication unit not to wirelessly transmit the identification information on the connectable wireless terminal recognized not to be the opposite attribute wireless terminal to the instruction attribute wireless terminal when the recognition unit recognizes that the connectable wireless terminal is not the opposite attribute wireless terminal,

wherein the first communication control unit controls the first communication unit to perform a process of establishing a wireless connection with the opposite attribute wireless terminal designated by wirelessly received information when the first communication unit receives, from the instruction attribute wireless terminal, the information for instructing video transmission and designating the opposite attribute wireless terminal that is a connection destination, and

wherein the instruction attribute wireless terminal is defined as a wireless terminal that has the instruction attribute, the instruction attribute wireless terminal being different from either the own terminal or the connectable wireless terminal.

4. The wireless system according to claim 3, wherein the instruction attribute wireless terminal comprises:
