Since the present invention is configured as described above, the following effects can be obtained.
When a user event occurs due to a user operation such as cursor movement or screen scrolling during content viewing, drawing of dynamic elements in HTML content is removed to preferentially perform drawing processing such as cursor movement or screen scrolling. Therefore, user operability can be improved. When user event processing by user operation is not performed, only the dynamic element part in the HTML content is updated and rendered, so there is no need to render the unupdated part of the static part, and the processing load is reduced. Can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a system to which a content display apparatus according to an embodiment of the present invention is applied. In FIG. 1, the system determines that data received via the network 12 is display content, a network control device 101 that is passed to the content display device 100, and content storage that temporarily stores the received data in a format that can be interpreted. A memory 102, a remote control device 103 that generates a user operation event by a user operation, and a display display 13 on which the content display device 100 interprets and outputs data stored in the content storage memory 102 are provided.

  FIG. 2 is a block diagram of the content display apparatus according to the embodiment of the present invention. The content display device 100 of FIG. 2 receives a user event received from the content reading unit 201 that reads an HTML file via the network control device 101 and the remote control device 103 related to screen display by cursor movement, screen scrolling, page transition, and the like. The user event processing unit 202 that processes the user event, the user event acquisition / notification unit 203 that notifies the user event processing unit 202 of the user event received from the remote control device 103, and the process start notification and processing end from the user event processing unit 202 A content analysis unit 204 that determines whether or not the event processing state is determined by the notification and analyzes the content read from the content reading unit 201 and interprets the static element tag in the content, and the content The analysis result of the analysis unit 204 and A layout determining section 205 determines a screen layout by processing information from over The event processing unit 202, in accordance with the screen layout determined by the layout determining section 205 has content display unit 206 to display content on a screen. Further, in a normal state other than the user event processing state, the content analysis unit 204 analyzes the content read from the content reading unit 201, interprets the dynamic element tag in the content, and the layout determination unit 205 displays the analysis result. Thus, the screen layout is determined, and the content display unit 206 displays the screen according to the determined screen layout.

  The operation of the content display device configured as described above will be described. FIG. 3 shows a description example of dynamic elements and static elements of HTML content in the embodiment of the present invention. An HTML content file 30 illustrated in FIG. 3 is content information to be read by the content display device 100. The HTML content file 30 is described in such a manner that a dynamic element and a static element are overlapped by a “div” tag. Each target tag has a “motion” attribute defined as an indicator, and each tag of a dynamic element such as a flow character, animation image, or moving image content is represented by “motion =“ on ””. On the other hand, each tag of a static element such as a normal character or a still image is represented by “motion =“ off ””.

  Next, the operation of the content display apparatus that reads the content file described as described above and displays it on the screen will be described. FIG. 4 is a flowchart for explaining the operation of the content display apparatus according to the embodiment of the present invention. First, in response to a page transition request from the user, the content described in the content file is read by the content reading unit (processing step S01), and the content analysis unit changes the current state to the user event processing state by the page transition event. Set (processing step S02). Next, the current state is acquired (processing step S03), the current state is determined (processing step S04), and in the case of the user event processing state, the static part of the content read above, that is, “motion = Interpret the tag specified by the “off” specifier and ignore the tag specified by the “motion =” on ”specifier. Further, in this case, a tag having no “motion” attribute as a specifier as shown in FIG. 5 described later is interpreted (processing step S05). Next, the user event processing unit performs processing corresponding to each type of user event (processing step S07). For example, in the case of cursor movement, an item to be focused is notified to the layout determination unit, and in the case of screen scrolling, the scroll amount or the like is notified to the layout determination unit. The layout determination unit determines a layout to be displayed on the screen based on the contents interpreted by the content analysis unit and the information notified by the user event processing unit (processing step S08), and performs a drawing process on the screen by the content display unit. (Processing step S09). At this time, a screen composed only of static elements is drawn on the screen, and for example, a screen shown in FIG. 6 to be described later is displayed on the display. Next, event reception processing of the event reception / notification unit is performed, a waiting user event is acquired (processing step S10), and it is determined whether there is a processing waiting event (processing step S11). Here, if there is a waiting user event (YES), it is determined whether it is an end event (processing step S12). If it is not an end event (NO), the current state is set as the user event processing state ( Processing step S13) returns to the step of acquiring the current state (processing step S03). On the other hand, when there is no waiting user event (NO), the current state is set to the normal state (processing step S14). When the current state is a normal state other than the user event processing state (NO in processing step S04), the content read by the content reading unit 201 is analyzed (processing step S06), that is, the dynamic part in the content, that is, The tag specified by the specifier of “motion =” on ”” is interpreted, and the tag specified by the specifier of “motion =” off ”” is ignored. Further, in this case, a tag that does not have a “motion” attribute as a specifier as shown in FIG. 5 described later is not interpreted, and only the dynamic part is interpreted. Next, the layout determination unit 205 determines the screen layout of this part only with the dynamic part of the content interpreted by the content analysis unit 204 (processing step S07), and the content display unit 206 performs screen drawing of only this part. (Processing step S08). At this time, a screen as shown in FIG. 7 to be described later is displayed on the display 13 and the static element portion is not updated, and the drawing of only the dynamic element portion is updated and displayed.

  FIG. 5 shows a description example of a part of HTML content in the embodiment of the present invention. The HTML content file 50 is content to be read by the content display device 100, and each tag does not have a specifier that specifies the “motion” attribute. The HTML content file 50 describes the display position information of the image normal with a “div” tag. In the “div” tag, an absolute position “position” attribute that specifies the position of the content of the object from the beginning is defined as an indicator.

  FIG. 6 shows an example of a static display screen displayed in the user event processing state in the embodiment of the present invention. In the example of the static display screen in the figure, for example, as specified by “top: 100pt left: 100pt height: 20pt width: 50pt” of the HTML content file 30, the upper position, the left position, the height, and the width are set. “Static characters” of 100, 100, 20, and 50 points are displayed. Similarly, by specifying a <a> tag for performing a link, a link is made to jump to the Web page address of “http: //hogehoge/link.html”. Click on "Link" to display its contents. A button is displayed by the description of the “button” tag. The upper right image Picture and the lower left image Picture 2 on the screen are still images specified by the “motion =“ off ”” specifier in the “div” tag. The lower right image normal on the screen displays a still image normal at an absolute position having, for example, an upper position, a left position, a height, and a width of 250, 400, 120, and 160 points, respectively.

  FIG. 7 shows an example of a dynamic display screen displayed in a normal state in the embodiment of the present invention. In the example of the dynamic display screen shown in the figure, for example, as specified by “top: 100pt left: 100pt height: 20pt width: 50pt” of the HTML content file 30, the upper position, the left position, the height, and the width are set. “Flow characters” of 100, 100, 20, and 50 points are displayed. Similarly, by specifying a <a> tag for performing a link, a link is made to jump to the Web page address of “http: //hogehoge/link.html”. Click on "Link" to display its contents. A button is displayed by the description of the “button” tag. The upper right image Animation and the lower left image Movie on the screen are moving images specified by a “motion =“ on ”” specifier in a “div” tag. The lower right image normal on the screen displays a still image normal at an absolute position having, for example, an upper position, a left position, a height, and a width of 250, 400, 120, and 160 points, respectively.

  According to such a content display apparatus of the embodiment of the present invention, the content analysis unit 204 of the HTML browser determines whether the dynamic element of the tag described in the HTML content is static or not depending on whether or not the user event processing state is set. By interpreting which of the elements to display, the processing load of the user event processing by the user operation can be reduced, and the operability of the user operation can be improved.

  In the above description, the configuration for displaying the HTML content in the content display device has been described as an example. However, the present invention can be similarly applied to other televisions, mobile phones, and car navigation systems.

  As described above, according to the embodiment of the present invention, depending on whether the content analysis unit 204 of the HTML browser is in the user event processing state, the dynamic element and the static element of the tag described in the HTML content By interpreting which one is displayed, it is possible to reduce the processing load of the user event processing by the user operation, and there is an advantage that the operability of the user operation is improved.

  The content display device and the content display method of the present invention eliminates drawing of dynamic elements in HTML content when a user event occurs due to a user operation such as cursor movement or screen scrolling during content viewing. Since drawing processing by screen scrolling can be preferentially processed, improvement of user operability can be realized, and when user event processing by user operation is not performed, only dynamic element parts in HTML content are updated and drawn Since the processing is performed, there is no need to draw the non-updated portion of the static portion, which has the effect of reducing the processing load, and a browser display that displays HTML content for embedded devices that do not include a high-speed CPU Methods, methods for improving the operability of user operations on embedded devices with browsers, etc. It is useful.
