Video transmission and display system

A connection method conforming to a video radio transmission standard between a video transmission device and a video reception and display device in a video display system that transmits a video from the video transmission device equipped with neither a display unit nor an operation unit for realizing a user interface to the video reception and display device according to the video radio transmission standard for transmitting a video through one-to-one direct radio communication and performs display,

• the connection method comprising:
• (a) a step of the video transmission device connecting the video transmission device and the video reception and display device according to the video radio transmission standard and establishing first connection;
• and
• (b) a step of the video transmission device connecting the video transmission device and the video reception and display device peer-to-peer prior to the establishment of the first connection and establishing second connection, wherein
• the step (b) is started according to any one of acquisition of a request from the video reception and display device and occurrence of an opportunity in the video transmission device.

A computer program for connecting a video transmission device and a video reception and display device according to a video radio transmission standard in a video display system that transmits a video from the video transmission device equipped with neither a display unit nor an operation unit for realizing a user interface to the video reception and display device according to the video radio transmission standard for transmitting a video through one-to-one direct radio communication and performs display,

• the computer program causing a computer to realize:
• a function of connecting the video transmission device and the video reception and display device according to the video radio transmission standard and establishing first connection;
• and
• a function of connecting the video transmission device and the video reception and display device peer-to-peer prior to the establishment of the first connection and establishing second connection, wherein the function of establishing the second connection is started according to any one of acquisition of a request from the video reception and display device and occurrence of an opportunity in the video transmission device.

A video reception and display device comprising:

• a peculiar information acquisition device for acquiring peculiar information provided by a video transmission device;
• and
• a reception-side connection control unit configured to control establishment of connection between the video transmission device and the video reception and display device, the reception-side connection control unit controlling establishment of first connection for connecting the video transmission device and the video reception and display device according to a video radio transmission standard for transmitting a video through one-to-one direct radio communication and second connection for connecting the video transmission device and the video reception and display device peer-to-peer prior to the establishment of the first connection, wherein
• the reception-side control unit acquires the peculiar information with the peculiar information acquisition device before a start of processing of establishment of the second connection and transmits, after the establishment of the second connection, the acquired peculiar information to the video transmission device as connection identification information indicating that the video reception and display device is a connection target conforming to the video radio transmission standard.
