(Embodiment 1)
FIG. 2 shows a schematic configuration of the operation terminal, the data recording device, and the data display device in the first embodiment. In the present embodiment, AV data stored in a movie (data recording device 203) by operating a portable terminal (operation terminal 204) is transferred to a recorder device (data recording device 201) that can transfer AV data to the movie. A method for differential dubbing will be described.

  FIG. 3 is a sequence diagram among the data recording device 201, the data recording device 203, and the operation terminal 204. 206 is a router, and 207 is the Internet.

  First, the operation terminal 204 searches for the data recording device 201 and the data recording device 203 connected to the network using UPnP (registered trademark) (Universal Plug and Play) (S301).

  When the operation terminal 204 determines that the discovered device is a device capable of distributing AV data and capable of dubbing, the AV data stored in the data recording device from the data recording device 201 and the data recording device 203 is obtained. Are obtained (S302 to S303). Non-patent document 2 has a detailed description of a device discovery method using UPnP (registered trademark) technology and a determination method of a server device capable of distributing AV data. Regarding details of the AV data list acquisition method, refer to Non-Patent Document 3 for details.

  The operation terminal 204 determines an icon to be displayed based on the received capability information and AV data list information of the device. In the example of the present embodiment, “dubbing capability” is included in the capability information of the data recording device 201 and the data recording device 203, and the AV data list of the data recording device 201 and the AV data of the data recording device 203 are also included. When there is a difference in the list, the operation terminal 204 displays a difference upload icon (101) as shown in FIG. Details of the method for displaying the differential upload icon will be described later.

  If there is no icon to be displayed, the process is terminated (S305).

  When the differential upload icon is selected, the operation terminal 204 transmits a dubbing request to the data recording device 203 (S306).

  When receiving the dubbing request from the operation terminal 204, the data recording device 203 transmits a CreateObject request to the data recording device 201 (S307). The CreateObject request is defined by UPnP (registered trademark), and is used when dubbing AV data to a partner device. For details on CreateObject, refer to Non-Patent Document 3 for details.

  When receiving the success response to the CreateObject request from the data recording apparatus 201, the data recording apparatus 203 starts transmitting AV data to the data recording apparatus 201 (S308). Regarding the AV data transmission method, refer to Non-Patent Document 1 for details.

  Next, a description will be given of a method in which the operation terminal 204 receives capability information and AV data list information from a data recording device on the network and displays a differential upload icon.

  First, the operation terminal 204 transmits an M-SEARCH request (S401). The M-SEARCH request is transmitted to search for devices connected on the network. Regarding the M-SEARCH request, refer to Non-Patent Document 2 for detailed description. Devices that can respond to the M-SEARCH request (data recording device 201, data recording device 203) transmit an M-SEARCH response to the device (operation terminal 204) that transmitted the M-SEARCH request (S402).

  The operation terminal 204 that has received the M-SEARCH response acquires capability information (Device Description Document) from the data recording device 201 and the data recording device 203 that have transmitted the M-SEARCH response (S403 to S404). Regarding the details of the method of acquiring the capability information of the device and the contents of the capability information, refer to Non-Patent Document 1 and Non-Patent Document 2 for detailed description. The operation terminal 204 can confirm whether the data recording device 201 and the data recording device 203 support dubbing of AV data by referring to the acquired capability information.

Regarding the capability information, there is a detailed description in Non-Patent Document 1, so please refer to that.

  The operation terminal 204 confirms whether or not the “av-upload” value is included in the capability information acquired from the device. If included, the operation terminal 204 is a data recording device capable of dubbing AV data. If it is not included, it is determined that the data recording apparatus cannot copy the AV data. Here, in the example of the present embodiment, it is determined whether or not dubbing of AV data is possible using UPnP capability information. However, the present invention is not limited to the method described above, and other You may judge using the method of.

  FIG. 6 is a sequence diagram when the operation terminal 204 acquires AV data list information from the data recording device 201 and the data recording device 203.

  The operation terminal 204 transmits a CDS: Browse request based on the capability information acquired from the data recording device 201 and the data recording device 203 (S601). Upon receiving the CDS: Browse request, the data recording device 203 transmits a CDS: Browse response including AV data list information to the operation terminal 204 (S602). The CDS: Browse response includes metadata including attribute information of the AV data. The CDS: Browse request / response is used when acquiring AV data list information, and is defined by UPnP (registered trademark). Regarding the details of the CDS: Browse request / response, refer to Non-Patent Document 3 for a detailed description.

  7 and 8 are diagrams conceptually showing icon data display conditions managed by the operation terminal 204. FIG. The icon data display condition includes a device ID, device capability, data type, data ID, and data name.

  FIG. 7 is a diagram conceptually showing the device capability information acquired from the data recording device 201 and the data recording device 203.

  The device ID is an ID assigned to each device by the operation terminal 204. In the example of the present embodiment, “201” is assigned to the data recording apparatus 201, and “203” is assigned to the data recording apparatus 203.

  The device capability is created based on capability information acquired from the data recording device by the operation terminal. Since the data recording device 201 and the data recording device 203 of the example of the present embodiment support AV data list distribution (Browse) and dubbing (av-upload), data indicating that it corresponds to the above capability Is registered. The device capabilities are not limited to these, and include capability information of all data recording devices that can be controlled by the operation terminal via the network.

  Reference numerals 701 to 702 are capability information related to the data recording apparatus 201, and reference numerals 703 to 704 are capability information related to the data recording apparatus 203.

  In “701” and “703”, “Browse” indicating the ability to distribute the AV data list is registered.

  In “702” and “704”, “av-upload” indicating the capability of dubbing is registered.

  FIG. 8 is a diagram conceptually showing a list of AV data acquired from the data recording device 201 and the data recording device 203.

  Since the device ID has been described with reference to FIG.

  The data type represents the type of stored AV data. In the example of the present embodiment, there are “Video” representing video, “Audio” representing music, and “Image” representing a still image. The data recording device 201 stores “Image”, “Audio”, and “Video”, and the data recording device 203 stores “Video”. The data types are not limited to these, and include all types of types that can be processed by the data recording apparatus.
