  FIG. 3 is a sequence diagram between apparatuses in the first embodiment of the present invention.

  In FIG. 3, first, the communication terminal device 100 sends a server information acquisition response 702 to the player 200 when access to the server function in the communication terminal device 100 occurs from the player 200, that is, when a server information acquisition request 701 is received. Send. Specifically, when the second wireless communication unit 102 of the communication terminal apparatus 100 receives the server information acquisition request 701 from the player 200 via the wireless communication 610, the second wireless communication unit 102 sends the server information acquisition request 701 to the server function unit 108. To be notified. Upon receiving the server information acquisition request 701, the server function unit 108 transmits a server information acquisition response 702 via the second wireless communication unit 102.

  Similarly, when receiving a content list acquisition request 703 from the player 200, the communication terminal apparatus 100 transmits a content list acquisition response 704 including a list of contents held by the server function unit 108 to the player 200. When the content acquisition request 705 is received, the content held by the server function unit 108 is transferred as the content transfer 706.

In this example, two message types are used for information acquisition and content transfer request. However, the purpose of holding this type is that the server function receives control from another device having a controller function. And a history of whether or not the content transfer has been performed for another device is held, and another message type may be determined and held as long as it can satisfy this purpose.

  Next, the access history holding unit 112 confirms the information held by itself, and performs a process of determining whether both types of information acquisition message and content transfer request message are received from the same device. (Step S153). If it is received from the same device (YES in step S153), the device determined to be the same device is determined to be a player, and a process of holding information on the device is performed (step S154).

  Then, the second wireless communication unit 102 performs a process for determining whether or not communication by the wireless LAN is possible (step S155). If communication is possible, the above process is continued, and if communication is not possible, an access history holding process is performed. finish.

  In FIG. 6, first, the device control method determination unit 109 performs a determination process as to whether the device selected by the user is a player or a renderer (step S171). If the determination result is a player (player in step S171), the device control method determination unit 109 performs determination processing for performing player control by the infrared remote control application (step S172), and then the remote control unit 103 The infrared remote control application is activated, and processing for notifying the UI unit 110 of the display of the infrared remote control application operation screen is performed (step S173). On the other hand, when the determination result in step S171 is a renderer, the device control method determination unit 109 performs a determination process for performing renderer control using UPnP, UPnP AV, and the like represented by DLNA in wireless LAN communication. (Step S174) Subsequently, the renderer control unit 106 performs renderer control, and performs processing for notifying the display unit 113 in the UI unit 110 of the renderer control screen (step S175). With this processing, when a renderer device is selected as a playback device, the renderer control unit 106 can control the renderer 210 by transmitting a control command such as playback or stop via the second wireless communication unit 102. It becomes possible.
