[0039]
The embodiment of the data broadcast receiving method according to the present invention includes an operation responding to an operation of the remote controller 4 and an operation responding to an operation of the mouse 5. In the operation in response to the operation of the remote controller 4, the user first presses one of the color buttons 6 or the number buttons 7 of the remote controller 4. The data broadcast receiving device main body 2 extracts the operation corresponding to the button from the received BML document, and executes the operation.
[0040]
The operation includes an operation of selecting one option from a plurality of options displayed on the display surface of the display device 3. When the remote controller 4 further includes an up / down / left / right button and an enter button (not shown), when the up / down / left / right button is pressed, one of the plurality of options is displayed so as to be distinguishable from the other options. When the option button is pressed on the screen and the determination button is pressed, the option displayed on the display screen is selected so as to be distinguishable from other options.
[0041]
FIG. 6 shows an operation responding to the operation of the mouse 5. First, the user selects one point on the display surface of the display device 3 using the mouse 5. The data broadcast receiving device main body 2 specifies one of the color buttons 6 or the number buttons 7 of the remote controller 4 corresponding to the position of the point (step S1). When one button can be specified (step S2; YES), the data broadcast receiving device main body 2 displays a confirmation box 41 on the display surface of the display device 3. The user clicks the Yes button 43 using the mouse 5 when he wants to press the button described in the confirmation box 41, and clicks the No button 44 using the mouse 5 when he does not want to press that button. .
[0042]
When the Yes button 43 is clicked (step S3; YES), the data broadcast receiving device main body 2 executes an operation corresponding to the specified button (step S4). When the button is not specified from the point selected by the mouse 5 (step S2; NO), or when the NO button 44 is clicked (step S3; NO), the data broadcast receiving device main body 2 outputs the BML document. Do not perform the indicated action. That is, the data broadcast receiving device main body 2 executes the operation corresponding to the specified button only when the user approves. At this time, it is possible to prevent an erroneous operation of executing an operation corresponding to a button not intended by the user.
[0043]
The data broadcast receiving device main body 2 can also immediately execute the operation corresponding to the specified button without displaying the confirmation box 41. That is, when the user selects one point on the display surface of the display device 3 using the mouse 5, the data broadcast receiving device main body 2 selects one of the color buttons 6 or the number buttons 7 of the remote controller 4 corresponding to the position of the point. One button is specified. When the button can be specified, the data broadcast receiving device main body 2 executes an operation corresponding to the specified button. Furthermore, when the button is not specified from the point selected by the mouse 5, the data broadcast receiving device main body 2 does not execute the operation shown in the BML document.
[0044]
At this time, the user can intuitively input, and can quickly operate the data broadcast receiving apparatus 1 to quickly start the operation shown in the BML document. For example, according to such a data broadcast receiving apparatus 1, when a quiz program is being broadcast, the user can answer the quiz using the mouse 5 faster than answering the quiz using the remote controller 4. Can be.
[0045]
FIG. 7 shows in detail an embodiment of the operation of step S1 in the flowchart of FIG. 6, that is, the operation of specifying one of the color buttons 6 of the remote controller 4 based on a point selected by the mouse 5. ing. The data broadcast receiving device main body 2 analyzes whether or not two or more of the four colors of blue, red, green, and yellow are displayed on the display surface of the display device 3 (step S11). When the two or more colors are displayed on the display surface of the display device 2 (step S <b>11; YES), the data broadcast receiving device body 2 uses the point selected by the mouse 5 based on the point selected by the mouse 5. Then, the determination area 32-i is extracted from the display surface of the display device 3 (step S12).
[0046]
The determination area 32-i is also extracted in areas other than the area where the option is displayed in the operation of selecting one option from the plurality of options displayed on the display surface of the display device 3.
[0047]
The data broadcast receiving device main body 2 further recognizes the color displayed in the determination area 32-i (step S14). When the color is one of blue, red, green, and yellow (step S14; YES), the data broadcast receiving device main body 2 determines the point selected by the mouse 5 as the one of the color buttons 6 (Step S15).
[0048]
Generally, when asking the user to press the color button 6, the broadcast station creates a video in which an area in which a color is displayed and information (character strings and graphics) corresponding to the color are arranged. According to such a data broadcast receiving method, the user can intuitively input an area in which the color included in the video is displayed by pointing the area with the mouse 5.
[0049]
FIG. 8 shows another embodiment of the determination area extracted by the area extraction unit 23. The determination area 52-j (j = 1, 2, 3, 4) is surrounded by a contour 54-j. The outline 54-j is a predetermined color, for example, a white line. Each of the determination areas 52-j includes an area 53-j in which a color is displayed. For example, the area 53-1 displays blue, the area 53-2 displays red, the area 53-3 displays green, and the area 53-4 displays yellow. At this time, when the point inside the determination area 52-j is selected by the mouse 5, the color button 6 corresponding to the color of the area 53-j in step S13 of FIG. Attached.
[0050]
FIG. 9 shows another embodiment of the determination area extracted by the area extraction unit 23. The determination area 62-k (k = 1, 2, 3, 4) is surrounded by a contour 64-k. The outline 64-k is a predetermined color, for example, a white line. Characters 63-k are displayed in the determination areas 62-k, respectively. The characters 63-k are one or more digits.
[0051]
FIG. 10 shows the operation of step S1 in the flowchart of FIG. 6 when using the determination areas 62-1 to 62-4, that is, one of the number buttons 7 of the remote controller 4 based on the point selected by the mouse 5. 7 shows another embodiment of the operation of specifying one button in detail. The data broadcast receiving device main body 2 analyzes the BML document and analyzes whether or not the operation corresponding to the numeric button 7 of the remote controller 4 is described in the BML document (step S21). When such an operation is described in the BML document, the data broadcast receiving device main body 2 performs the determination on the determination area from the display surface of the display device 3 based on the point selected by the mouse 5. 62-k is extracted (step S22).
[0052]
The data broadcast receiving device main body 2 further recognizes the character displayed in the determination area 62-k (step S14). When the character is one of the characters 0 and 1 to 9 (step S24; YES), the data broadcast receiving device main body 2 corresponds to the point selected by the mouse 5 to that character of the number buttons 7 The corresponding button code is associated (step S25). The data broadcast receiving device main body 2 further corresponds to a code indicating an operation in which, when the character is a plurality of digits, the numeric buttons 7 corresponding to the digits are sequentially pressed from the upper digit of the numeral. Attach. For example, when the area in which the character “15” is described is clicked, the data broadcast receiving device main body 2 presses the “1” button of the number button 7 and then presses the “5” button of the number button 7. Corresponding to the operation to be performed.
[0053]
Generally, when asking the user to press the number button 7, the broadcast station creates a video in which numbers and information (character strings, figures) corresponding to the numbers are arranged. According to such a data broadcast receiving method, the user can intuitively input the area in which the numbers included in the video are displayed by pointing the area with the mouse 5.
