[Embodiment 1]
FIG. 1 is a block diagram showing an internal configuration of communication apparatus 100 according to the first embodiment.

  FIG. 2 is a schematic diagram illustrating a flow of data exchanged between the communication device 100 and the communication devices 120, 130, and 140 according to the first embodiment.

  The present embodiment will be described with reference to FIGS. 1 and 2. Here, the communication device 100 is, for example, a mobile phone or a PDA (Personal Digital Assistance), and the communication device 120 is, for example, a television, a PC, or the like. The relationship between the functions and screens of the communication device 100 and the communication device 120 may be reversed, or the same function or the same size screen may be used. Further, the communication devices 130 and 140 are, for example, a video server, a web server, a mail server, or the like that stores content.

  In FIG. 1, a communication apparatus 100 includes a communication unit 103 that is a communication interface having a function of exchanging data with an external communication device, a storage unit 102 that stores a communication program 180, a database 190, and the like, a user Includes an input unit 104 for operating the communication device 100 and a control unit 101 for controlling the operation of the communication device 100. Furthermore, the display part 105 which displays the image according to the instruction | indication from the control part 101 is provided.

  The control unit 101 includes a microprocessor, an FPGA (Field Programmable Gate Array), which is a programmable LSI (Large Scale Integration), and an ASIC (Application, which is an integrated circuit designed and manufactured for a specific application. Specific Integrated Circuit) or any other circuit having an arithmetic function may be used.

  The storage unit 102 may be any medium or circuit capable of holding data, such as a hard disk or a flash memory. The storage unit 102 stores a communication program 180 for causing the control unit 101 to perform predetermined processing, device information for specifying a device to be transmitted as a registered device, and device attributes of the registered device in association with each other. The stored database 190 is stored. The device information here is, for example, a value indicating a location such as an IP address in a home LAN (Local Area Network) or the like, but if an arrangement is made in advance between communication devices, the product name, etc. It may be simply a value for identifying the device. The device attribute represents the type of device such as a television or a PC. In accordance with the communication program 180, the control unit 101 performs various processes, arithmetic processes, and the like for each unit inside the communication apparatus 100. The database 190 is basically set by the manufacturer at the time of manufacture, but may be changed by the user using the input unit 104.

  The communication unit 103 performs data communication using short-range wireless communication technologies such as infrared communication and Bluetooth, IEEE802.11a, IEEE802.11b, IEEE802.11g, which are wireless LAN standards, and other wireless technologies and wired LAN technologies. Any communication interface may be used. In this embodiment, two types of communication interface 103A used when communicating with communication device 120 and communication interface 103B used when communicating with communication device 130 are used. The communication interface may be used to communicate with an external communication device.

  The input unit 104 is an interface through which a user can perform input such as a slide switch, a button switch, a touch panel, a keyboard, buttons mounted on a remote controller, a mouse, and the like.

  The display unit 105 includes a liquid crystal display, a CRT (Cathode Ray Tube), an FED (Field Emission Display), a PDP (Plasma Display Panel), an organic EL display (Organic Electro Luminescence Display), a display that adopts other image display methods such as a dot matrix. Any of the devices may be used. In addition, the display unit 105 may be a light emitter that turns on light, for example, an LED (Light Emitting Diode).

  In FIG. 2, the communication device 100 exchanges data with the communication devices 120 and 130. The communication device 120 has a function of receiving data via a communication interface when data including an information source identifier is transmitted from the communication device 100. The communication device 130 has a function of transmitting data including an information source identifier and attribute information to the communication device 100 from the communication interface. In addition, the communication device 120 exchanges data with the communication device 140 having the same function as the communication device 120. The information source identifier referred to here is a value indicating the location of information on a communication line such as a URI (Uniform Resource Identifier) or an IP address. If there is an agreement between the communication devices, for example, only a value for identifying information such as a file name, a product number, and a manufacturing number may be transmitted and complemented on the receiving side. The attribute information referred to here represents the type of device targeted by the content provided from the information source indicated by the information source identifier. For example, if the attribute information is “TV”, it indicates that it is for TV. Note that the communication method of the communication device for inputting information in a certain type of device may be substantially equivalent to representing the type of the device. For example, infrared communication is performed using attribute information “IR-link”. It may indicate that it is for a device that can Further, the attribute information may include a processing method for the content intended by the data sender, for example, information such as relaying and transferring of the content.

  After receiving the data including the information source identifier, the communication device 120 temporarily stores the data in the storage unit or selects a communication device to be connected based on the value of the information source identifier extracted from the data. It has a function of acquiring the content indicated by the original identifier via the communication interface and reproducing the acquired content on the display unit of the communication device 120.

  The transmission performed by the communication device 130 may be a response to the data request from the communication device 100 or may be in accordance with a request from the user of the communication device 130. For example, when the communication device 130 is a web server, data on the server is transmitted to the communication device 100 according to a request from the communication device 100, and when the communication device 130 is a mail server, communication is performed according to a user's mail transmission request. An e-mail is transmitted to the apparatus 100. The content indicated by the information source identifier transmitted by the communication device 130 is often on the communication device 130 when the communication device 130 is a web server, but for example, when the communication device 130 is a mail server. It may be on the communication device 140.

  FIG. 3 is a flowchart showing processing executed by communication device 100 according to the first embodiment.

  Hereinafter, with reference to FIG. 1 and FIG. 2, the communication processing performed between the communication apparatus 100 and the communication devices 120, 130, and 140 will be specifically described with reference to the flowchart of FIG. 3. Note that the processing of the communication apparatus 100 described below is executed by the control unit 101 operating according to the communication program 180 stored in the storage unit 102.

  As shown in FIG. 2 (S1), the communication unit 103B of the communication apparatus 100 receives data including the information source identifier and attribute information transmitted from the communication device 130 (S300). For example, a company that sells video content communicates a promotional mail including URL information of trailer data from the communication device 130 (for example, a mail server) in order to introduce the contents of the content to be newly released to the customer. When image data is transmitted to the device 100 (for example, a mobile phone) or the communication device 130 (for example, a web server) of a company that sells the product responds to a request from the communication device 100 (for example, a PDA), product image data There is a case where an HTML file including the URL information is transmitted to the communication apparatus 100. Note that the data including the information source identifier is not only received from the communication device 130 but also read out from the recording medium on which the data is recorded via the recording medium access unit when the communication apparatus 100 has the recording medium access unit. May be.

  After storing the acquired data in the storage unit 102, the control unit 101 analyzes the contents of the data and extracts information source identifiers and attribute information corresponding to the information source identifiers from the data (S302).

  FIG. 4 is a first example of data including an information source identifier and attribute information corresponding to the information source identifier. For example, if the data is in the HTML format as shown in FIG. 4, the URL information specified by the href attribute of the anchor tag is used as the information source identifier. Further, when the target attribute is designated, an attribute value, for example, “TV” is set as attribute information corresponding to the information source identifier.

  FIG. 5 is a second example of data including an information source identifier and attribute information corresponding to the information source identifier. Alternatively, if the data is in the XLink format as shown in FIG. 5, the URL information specified by the href attribute of the my: link tag is used as the information source identifier. Furthermore, when the role attribute is designated, an attribute value, for example, “IR-link” is set as attribute information corresponding to the information source identifier.

  Although the case where the data is in text format is shown here for explanation, it may be in binary format. Further, any format or attribute name may be used as long as an agreement is made between the communication devices in advance. For example, attribute information may be included in the information source identifier. Further, attribute information indicating that the content indicated by the URL is intended for television is embedded in the URL scheme (for example, “http_tv: // machine name / path”) or embedded in the path indicating the content. (For example, “scheme: // machine name / path? Target = tv”) or embedded in the file name of the content (for example, “scheme: // machine name / path.tv”). In this case, the control unit 101 needs to perform processing for scanning the character string of the URL and extracting the embedded attribute information. When there is a case where there is no agreement between the communication devices regarding the format or attribute name, when the information source identifier and attribute information are separated, the attribute information is ignored and only the information source identifier is used. It is easy to process.

  In step S304, the control unit 101 determines attribute information based on the received data. At this time, for the information source identifier extracted in S302, the value of the attribute information corresponding to the information source identifier is compared with the device attribute stored in the database 190, and the registered device corresponds to the device attribute corresponding to the attribute information. To determine whether or not

  For example, when the received data is in the HTML format as shown in FIG. 4 and has a value of the target attribute “TV”, the target attribute “TV” indicates that the content indicated by the URL is for TV. It is assumed that it is attribute information. At this time, in step S304, the control unit 101 determines whether the attribute attribute extracted in step S302 has a target attribute and has a value of “TV”. As a result, the communication apparatus 100 can easily identify whether the content indicated by the URL is intended for television based on the value of the target attribute. Whether there is a registered device as an attribute can also be identified.

  Alternatively, the received data is in the XLink format as shown in FIG. 5, and the role attribute “IR-link” is an attribute indicating that the content indicated by the URL is for a device capable of communicating with the communication apparatus 100 by infrared communication. Suppose that it is information. At this time, in S304, the control unit 101 determines whether the attribute information extracted in S302 has a role attribute and has a value of “IR-link”. As a result, the communication apparatus 100 can easily identify whether the content indicated by the URL is for a device capable of communicating by infrared communication based on the value of the role attribute, and based on the database 190. It is also possible to identify whether there is a registered device having a device attribute corresponding to “IR-link”.

  As described above, device information and device attributes of registered devices are stored in the database 190 in association with each other. However, device attributes and attribute information may be stored in association with each other. For example, the device attribute “TV” is associated with the attribute information “IR-link” as a device capable of infrared communication. In this case, the registered device may not be stored in the database 190. For example, by directing the transmission unit of the remote controller to which the user transmits infrared rays toward the device capable of infrared communication as the transmission destination, the device to be transmitted Is specified.

  Based on the determination made in S304, the control unit 101 instructs the display unit 105 to display the information source identifier (S305 and S306).

  FIG. 6 is a screen example displayed on the display unit 105 when the data shown in FIG. 4 is received.

  For example, when the data is as shown in FIG. 4, as shown in FIG. 6, when the link to the information source identifier whose target attribute has the value “TV” is selected as the transfer destination by the user. Instructs to display an icon representing the remote control (S305). In addition, for example, based on the determination made in S304, the display unit 105 may be instructed to use a different color for displaying the link depending on whether or not the attribute information is included. Accordingly, the user can easily determine which link can be transmitted to another communication device by displaying the screen on the display unit 105. If communication apparatus 100 does not have a function of transmitting data including an information source identifier for the television, it may be possible not to instruct display of a link to display unit 105 or to indicate that the remote control cannot be used. An instruction to display an icon may be given (S306). As a result, the user can avoid selecting a meaningless link.

  FIG. 7 is a screen example displayed on the display unit 105 when the data shown in FIG. 5 is received.

  Alternatively, for example, when the data is as shown in FIG. 5, as shown in FIG. 7, the title attribute of the my: link tag is displayed on the screen and the role attribute has a value of “IR-link”. If there is, there is an instruction to display an icon indicating that the “remote control transmission” function capable of infrared communication can be selected (“remote transmission” icon in FIG. 8). In addition, for example, an LED is provided in a button assigned to the “remote control transmission” function, and if the “remote control transmission” function is selectable based on the determination made in S304, an instruction is given to turn on the LED. Also good. Thereby, the user can easily determine which link can transmit to another communication device depending on whether or not the light is on. If the communication apparatus 100 does not have an infrared communication function, an instruction to display an icon indicating that the “remote control transmission” function can be selected on the display unit 105 may not be given (S306).

  Based on the screen display displayed on the display unit 105 in S305 or S306, the user uses the input unit 104 to select for which information source identifier the data including the information source identifier is to be transmitted (S307). .

  For example, in the case of the screen display as shown in FIG. 6, when the user presses the up / down / left / right button or the like (S308), the link is selected (S309), and which link is to be processed from the input unit 104. It is determined by the information given to the control unit 101.

  Alternatively, for example, when the screen is displayed as shown in FIG. 7, the user selects a link (S309) by pressing an up / down / left / right button or the like (S308), and the input unit 104 determines which link is to be processed. To the control unit 101.

  In S <b> 310, when the user presses a button assigned to the “link determination” function, information indicating that the link is determined as a processing target is given from the input unit 104 to the control unit 101. Next, the control unit 101 determines whether or not a button whose link is assigned to the “remote control transmission” function is pressed (S312). If the “remote control transmission” key is not pressed (No in S312), control unit 101 instructs communication unit 103B to perform connection processing on the data indicated by the selected information source identifier ( S311). If the “remote control transmission” key is pressed (Yes in S312), data including the selected information source identifier is transmitted from communication unit 103A to communication device 120 (S313).

  In FIG. 6, when the link for “sending the URL of the trailer by remote control” is selected and determined, information indicating that the link is determined as a processing target is provided from the input unit 104 to the control unit 101 in S310. Next, the control unit 101 determines that the button assigned to the “remote control transmission” function has been pressed (Yes in S312). When there is no value “TV” in the device attribute of the registered device, and there is an anchor tag having a value “target” in the target attribute, the user presses a button assigned to the “remote control transmission” function. In some cases, the input may be ignored, or a warning may be displayed indicating that the key input is invalid. Further, it may be set in advance so that data including the information source identifier specified by the href attribute of the anchor tag is transmitted to the communication device 120.

  Alternatively, in FIG. 7, when the “view trailer” link is selected and determined, information indicating that the link is determined as a processing target is given from the input unit 104 to the control unit 101 in S310. Further, if the user selects and determines the “remote transmission” icon, control unit 101 determines that the button assigned to the “remote transmission” function has been pressed (Yes in S312). An instruction is given to the communication device 120 to transmit data including the information source identifier specified by the href attribute of the locator tag whose role attribute extracted in S302 has a value of “IR-link” from the communication unit 103A ( S313). In addition, when the control unit 101 receives information that the button assigned to the “connect” function (“OK” button in FIG. 8) is pressed instead of the button assigned to the “remote control transmission” function in S312 ( No in S312), instructing that the communication unit 103B performs connection processing on the data indicated by the information source identifier specified by the href attribute of the locator tag whose role attribute extracted in S302 has a value of “link” (S311). If the device attribute of the registered device does not have a value “IR-link” and the locator tag has a role attribute “IR-link”, the button assigned to the “remote control transmission” function When the user presses, the input may be ignored, or a warning display indicating that the key input is invalid may be performed. Furthermore, data including an information source identifier specified by the href attribute of a locator tag having another role attribute may be set to be transmitted to the communication device 120.

(1. Example of transmitting information source identifier to other communication device)
In S314, the communication unit 103A receives the transmission request from the control unit 101, and transmits data including the information source identifier to the communication device 120 (see (S2) in FIG. 2). At this time, it is desirable that the control unit 101 instructs the display unit 105 to display what device can use the data indicated by the information source identifier. For example, if the content indicated by the URL is for TV and the communication method is infrared communication, the user may include the URL to be transmitted when a display such as “Please direct the infrared transmitter to a certain direction of the TV” is performed. You can easily know the devices that can use the data. If the communication method is infrared communication or NFC (Near Field Communication), the user can select a communication device as a transmission destination by physically bringing the communication device 100 and the communication device 120 close to each other. The communication device 100 itself does not need to have a communication destination selection function, and the database 190 may not store a registered device. However, when the communication means is Bluetooth, wireless LAN, etc., a list of registered devices that can be connected to the display unit 105 is displayed instead of being able to transmit to a physically distant communication device. The communication apparatus 100 needs to have a function of allowing the user to select a communication device as a transmission destination using the input unit 104.

  For example, the communication device 100 transmits inquiry data (or data for inquiring what kind of data is available) as to whether or not the data indicated by the information source identifier can be used at a predetermined multicast address, and the received communication device If data is available, 120 includes data including information such as an IP address, a port number, and a host name on which data including an information source identifier is waiting, and information indicating what data is available. The included data is returned to the communication apparatus 100. The communication device 100 stores the device that has sent the reply as a registered device in the database 190, and displays a list of devices that can use the data indicated by the information source identifier among the registered devices on the display unit 105, and the user The data including the information source identifier is transmitted to the device selected by the method described above with respect to the IP address and the port number included in the returned data.

  In FIG. 2 (S2), the data transmitted to the communication device 120 together with the information source identifier includes, for example, data representing the content content indicated by the information source identifier. As a data acquisition source, for example, a character string sandwiched between anchor tags in the case of FIG. 4 is used, or a character string value of a title attribute of a locator tag is used in the case of FIG. Is possible. Thereby, in the communication device 120 that has received the data, when the user selects a previously stored information source identifier, it is possible to facilitate the user's selection by displaying data representing the contents of the content. It becomes possible.

  Alternatively, as data transmitted to the communication device 120 together with the information source identifier, for example, there is an ID that can identify the communication device 100. As the ID value, for example, a device ID of the communication device or a value registered in the communication device 100 (for example, a telephone number or a mail address) can be used. As a result, in the communication device 120 that has received the data, the transmitted information source identifier can be classified and stored for each ID.

  Alternatively, as data to be transmitted to the communication device 120 together with the information source identifier, for example, when the communication device 130 is a web server, the data is transmitted from the communication device 130 together with the information source identifier, and communication with the communication device 130 is performed. Sometimes there is a cookie transmitted to the communication device 130. Thus, in the communication device 120 that has received the data, the cookie transmitted from the communication device 100 is transmitted at the time of communication with the communication device 130, so that the user who has connected from the communication device 120 has previously communicated with the communication device 120. It is possible to identify that the user is the same as the user connected from 100 to the communication device 130.

  Alternatively, as data to be transmitted to the communication device 120 together with the information source identifier, for example, the data is transmitted from the communication device 130 together with the information source identifier or the user, and is encrypted from the communication device 130 when communicating with the communication device 130. There is a content decryption key for decrypting the sent content. As a result, in the communication device 120 that has received the data, it is possible to decrypt and reproduce the content received by requesting the communication device 130 using the content decryption key.

  Alternatively, as data to be transmitted to the communication device 120 together with the information source identifier, for example, the communication device 120 that has received the data immediately connects to the data indicated by the information source identifier, or information in the communication device 120 is temporarily stored. You may enter a value that specifies whether to store the original identifier. Thus, before transmission to the communication device 120, the user specifies whether to play the content immediately after reception, and the communication device 120 that has received the data immediately receives the content based on the specified value. It becomes possible to determine whether or not to go to obtain.

  Thereafter, the communication device 120 receives the data including the information source identifier, and then extracts the information source identifier from the data. Based on the extracted information source identifier value, the communication device 120 owns the content to the communication device 130 or the communication device 140. Then, the content transmission is requested (see (S3) and (S3 ′) in FIG. 2).
