Therefore, terminal devices such as telephones and television receivers connected to the respective networks are necessary, and cooperation between these terminal devices is difficult.

  For example, when viewing detailed program information while watching a television broadcast program, the user inputs the URI (Uniform Resource Identifier) of the program homepage described in the program information and the program name from a terminal that can be connected to the Internet. It is necessary to search and browse the program homepage. In this way, the user has to select and collect information provided individually on each network.

  On the other hand, in digital television broadcasting that has become widespread in recent years, information such as program outlines and performers is provided by an electronic program guide (EPG) and linked data broadcasting, etc. It can be displayed on the screen together with the program being viewed. In addition, terminal devices that can be connected to both the television broadcasting network and the Internet, such as a television receiver that can be connected to the Internet and a computer that incorporates a tuner for television broadcasting, have become widespread. In such a terminal device, a method of displaying a television broadcast program and information that can be acquired from the Internet in association with each other has been devised.

  For example, Patent Literature 1 discloses a system that displays detailed information about a currently viewed program and related advertisements in an information area superimposed on a part of the display screen of the currently viewed television program. Yes. The information displayed in the information area can include a link to information available on the Internet or EPG. When the viewer selects the link, the information acquired from the link destination is displayed in the information area or on the display screen. Is displayed throughout.

(Notification information generation process)
Next, details of the notification information generation process performed by the notification information generation unit 106 will be described. FIG. 4 is a diagram illustrating a display example of notification information displayed on the display unit 109 of the content viewing apparatus 100. Note that the notification information example in FIG. 4 is generated from the metadata in FIG. 3. The operation of the notification information generation unit 106 when generating the notification information of FIG. 4 from the metadata of FIG. 3 will be described below.

  The notification information generation unit 106 interprets the metadata in order from the beginning of the data, and generates notification information using tags included in the data. In the example of FIG. 3, first, the <product> tag is detected by the notification information generation unit 106. Since <product> is a tag representing product information, the notification information generation unit 106 generates notification information using the contents described in the portion surrounded by <product>. Here, the notification information 201 of FIG. 4 is generated using the items of the <name> <maker> <price> tags in the <product> tag.

  Next, the notification information generation unit 106 generates notification information about the <url> tag in the <product> tag. Since the <url> tag is access information for accessing the home page on which the product is posted, the notification information generation unit 106 notifies that the product can be examined in detail on the Internet. 202 is generated.

  Furthermore, the notification information generation unit 106 generates notification information based on the contents described in the <information> tag. In the example of FIG. 3, since it can be recognized from the content of the <info-name> tag that the information is for purchasing a product, notification information 203 for notifying that there is information related to the purchase of the product is generated.

  In addition, the notification information 201-203 produced | generated here is an example, Comprising: Notification information may be produced | generated by formats other than the above-mentioned example. For example, in the above example, the <url> and <information> tag information is generated in a format that is displayed by the user's selection. However, the URL is described in the <url> tag or the <phone> tag. Notification information may be generated so as to display the telephone number itself.

  Such a method for generating the notification information can be freely customized by the user on the terminal side. As a result, only the information required by the user can be extracted and displayed in a display format according to the user's preference, improving convenience for the user.

  The notification information 201 to 203 generated in this way is input to the display control unit 107, and is superimposed on the video of the program content and output to the display unit 109. The notification information may be output to the display unit 109 at a timing when it is detected that the user has pressed a predetermined button. Alternatively, notification information may be output when a keyword registered in advance by the user exists in the metadata.

  The notification information 202 and 203 shown in FIG. 4 is configured to be selectable by the user operating the controller 112 or the like. Under the state where the notification information of FIG. 4 is displayed on the display unit 109, a function of selecting the notification information 202 and 203 is assigned to any button of the controller 112. The user selects either the notification information 202 or 203 by pressing the button. Thus, by generating notification information that can be selected by the user, it is possible to selectively display information requested by the user from the information displayed on the screen. Of the large amount of information given by the metadata, Only the information necessary for the user can be selectively displayed.

  When the user presses the button of the controller 112 to which the notification information 202 is assigned on the display screen illustrated in FIG. 4, a signal indicating that the button has been pressed is input to the input unit 105. The transmitted signal is transmitted to the control unit 104. The control unit 104 detects that the notification information 202 has been selected based on the signal transmitted from the input unit 105, and executes processing corresponding to the selected notification information.

  The control unit 104 may be preliminarily given information about processing to be executed corresponding to each notification information from the notification information generation unit 106, and may perform processing corresponding to each notification information. Alternatively, when the notification information is selected, an inquiry is made to the notification information generation unit 106 based on the selected notification information, and the process is executed based on the information given from the notification information generation unit 106 Also good. Alternatively, the notification information generation unit 106 stores information on processing to be executed corresponding to each notification information in a storage unit (not shown), and the control unit 104 refers to the information stored in the storage unit. Thus, the process may be executed.

  In the example of FIG. 4, the notification information 202 is generated corresponding to the <url> tag in the <product> tag. When the notification information 202 is selected, the Web access unit 110 inserts the notification information 202 in the <url> tag. Processing to access the described URL is executed. As a result, a product home page 212 as shown in FIG. 5 is displayed on the display unit 109 together with the television program display screen 210. FIG. 5 shows an example of a display screen displayed on the display unit 109 when the notification information 202 shown in FIG. 4 is selected.

  The notification information 203 is information related to the product purchase described in the <information> tag. When the notification information 203 is selected, the notification information generation unit 106 notifies the notification information based on the information in the <information> tag. Is generated and displayed on the display unit 109. As described above, the process and the combination corresponding to each notification information are determined by the notification information generation unit 106 when the notification information is generated, and are given to the control unit 104.

  FIG. 6 shows an example of a display screen displayed on the display unit 109 when the notification information 203 is selected. When the control unit 104 detects that the knowledge information 203 has been selected, the control unit 104 controls the notification information generation unit 106 to generate notification information related to product purchase as shown in FIG. Since the metadata shown in FIG. 3 describes two product purchase means, online purchase and telephone purchase on the Web, the notification information generating unit 106 provides notification information 204 corresponding to each of the Web and telephone. And notification information 205 is generated.
