Description

  The present invention relates to a wireless communication system, an output device, and a wireless connection method. For example, the present invention relates to a wireless communication system, an output device, and a wireless connection method using a wireless AV device using wireless LAN such as 802.11a and 802.11b and wireless communication such as Bluetooth.

  Recently, wireless AV devices using wireless communication, such as separating only a display portion such as a display and transmitting and displaying a video signal on the display portion wirelessly, have been widely used.

  FIG. 8 shows a configuration diagram of a conventional wireless TV receiver using wireless communication.

  This wireless TV receiver is configured by separating a broadcast receiving device 311 that receives broadcast waves and an audio / video display device 300 that displays broadcast waves received by the broadcast receiving device 311.

  The broadcast receiving device 311 and the audio / video display device 300 are connected via a wireless network. In order to establish a wireless connection between the broadcast receiving device 311 and the audio / video display device 300, the broadcast receiving device 311 includes audio / video as information necessary for wireless connection with the audio / video display device 300 in advance. Information (bssid and ssid) for specifying the display device 300 and a common encryption key (such as a WEP key) for encrypting data on the wireless network are held. Similarly, in the audio / video display device 300, information (bssid or ssid) for specifying the broadcast receiving device 311 and information on the wireless network as information necessary for establishing a wireless connection with the broadcast receiving device 311 in advance. A common encryption key (such as a WEP key) for encryption is held.

  When the broadcast receiving device 311 and the audio / video display device 300 make a wireless connection after the power is turned on, the connection waiting side enters the connection waiting state based on the stored information, and the device other than the registered device No connection is made.

  In addition, the connection side uses the information that identifies the held partner to perform wireless connection with a predetermined device.

  Since the wireless connection is performed using the information necessary for performing the wireless connection stored in advance in the audio / video display device 300 and the broadcast receiving device 311, the user can perform the audio without setting the wireless connection. A wireless connection can be established between the video display device 300 and the broadcast receiving device 311.

  However, a wireless AV device using conventional wireless communication cannot establish a wireless connection with a device other than a device preset as a communication partner.

  That is, for example, in a wireless TV receiver that is already on the market as shown in FIG. 8, information necessary for wireless connection is registered in the audio / video display device 300 and the broadcast receiving device 311 at the time of shipment from the manufacturer. And the user cannot change that information.

  Further, the audio / video display device 300 and the broadcast receiving device 311 do not perform wireless connection with a device that does not hold information on a communication partner device necessary for wireless connection when wireless connection is executed. Therefore, as shown in FIG. 8, the audio / video display device 300 cannot newly construct a wireless network with an audio / video output device (for example, the video storage device 312) other than the broadcast receiving device 311.

  If you want to display video data from an audio / video output device other than the broadcast receiving device 311 (for example, the video storage device 312) with a conventional wireless TV receiver, connect it to the broadcast receiving device 311 in a wired manner. Wireless connection was made via the receiving device 311 and the audio / video display device 300 was displayed. Or, when a new device is connected, such as displaying by connecting to the audio / video display device 300 by wire, it has been supported by connecting to a device that has already configured a wireless network. .

  Further, even in an AV system, such as a wireless network such as a personal computer, when a user interface is provided so that a wireless connection destination can be registered, knowledge about the wireless network is required for setting.

  In addition, when the audio / video output device such as the broadcast receiving device 311 or the video storage device 312 has a user interface that can register the wireless connection destination, the audio / video output device has no display device or Since many devices can display only a very small amount of information, it is necessary to add a display device for inputting and confirming wireless connection information.

  Further, every time the audio / display output device such as the audio / video display device 300 is changed, it is necessary to input / change information necessary for wireless connection.
