Abstract

A display and a touch panel can replace operation of a remote control. Conversion/management analyzes BML description for realizing the software remote control function corresponding to operation of a special key of the remote control on display with a BML browser and makes function assignment of the touch panel. When event elements are crowded, the proximity of the specified position is once enlarged for preventing erroneous operation from occurring.

2. The digital broadcast reception apparatus according to claim 1, wherein:

the digital broadcast contains the image information for the input operation as a content described in a predetermined document description language for broadcast;

the content is associated with an event caused by the input operation to the remote control;

the touch panel is placed on a surface of a screen on which the display unit displays the image information for the input operation;

the analysis unit displays an operation guide on the display unit corresponding to the area assignment; and

when the user touches an area of the touch panel corresponding to the operation guide display, the control unit causes an event, which is caused by the input operation to the remote control assigned to the area of the touch panel corresponding to the operation guide display.

3. The digital broadcast reception apparatus according to claim 1, wherein:

when input operation functions of the remote control contains an input operation function, which is assigned to no area by the analysis of the operation concerning the remote control, the analysis unit assigns a touch operation area of the touch panel for a software remote control function to the input operation function, which is assigned to no area by the analysis of the operation concerning the remote control; and

the analysis unit displays an operation guide of the software remote control function on the display unit corresponding to the touch operation area for the software remote control function area.

4. The digital broadcast reception apparatus according to claim 3, wherein:

the analysis unit assigns the touch operation area for the software remote control function to the touch panel so as not to overlap the area assigned by analyzing the operation.

5. The digital broadcast reception apparatus according to claim 4, wherein:

if an appropriate area assigned to the software remote control function does not exist in the touch panel, the analysis unit moves an assigned area every given time.

6. The digital broadcast reception apparatus according to claim 3, wherein

when the user does not perform an input operation to the software remote control function within a predetermined time, the analysis unit stops the assignment to the software remote control function and stops the operation guide display for the software remote control function.

7. The digital broadcast reception apparatus according to claim 3, wherein:

the analysis unit assigns an area for starting the software remote control function to an area of the touch panel where the display unit does not display the image information for the input operation; and

when the control unit detects a touch operation to the area for starting the software remote control function, the software remote control function is started.

8. The digital broadcast reception apparatus according to claim 3, further comprising:

a voice recognition unit for recognizing voice input, wherein;

the analysis unit starts the software remote control function when the voice recognition unit recognizes a predetermined instruction.

9. The digital broadcast reception apparatus according to claim 3, wherein:

the analysis unit switches the assignment to the operation guide display on the display unit corresponding to the touch panel area assigned for the software remote control function between effectiveness and ineffectiveness at preset time intervals.

10. The digital broadcast reception apparatus according to claim 2, wherein:

the analysis unit displays on the display unit a cursor and an event element, which is associated with a predetermined event and can be specified based on a position of the cursor;

the analysis unit associates a movement of a touch position of the touch panel detected by the control unit with an event for the remote control to move the cursor; and

the analysis unit associates an operation of stopping touch of the touch panel and breaking away from the touch panel detected by the control unit with an event for the remote control to determine the event element at the cursor position.

11. The digital broadcast reception apparatus according to claim 10, wherein:

the control unit determines as to whether or not the event element exists in the image information for the input operation on the display unit corresponding to a position where the user stops touch of the touch panel and breaks away from the touch panel; and

when the control unit determines that the event element does not exist, the control unit does not interpret user'"'"'s operation as the determination operation.

12. The digital broadcast reception apparatus according to claim 2, wherein:

the analysis unit displays an event element on the display unit in a display mode so that the event element is distinguished from other images.

13. The digital broadcast reception apparatus according to claim 1, wherein:

the analysis unit determines as to whether or not assignment of touch areas of the touch panel based on the analysis result is crowded in accordance with a predetermined criterion;
