Description

  The present invention relates to a digital television receiver, and more particularly, to a plane configuration switching function defined in STD-B24 Volume 1 Part 1 6.2 of the Association of Radio Industries and Businesses (ARIB). The present invention relates to a digital television receiver and a display method of the digital television receiver.

  In recent years, as the applications of digital television receivers have been enriched, their usage has tended to diversify. For this reason, there are applications that are difficult to use or cannot be used because it is difficult to set and use even applications that are desired to be used.

  It is only necessary to be able to operate the application after reading the instruction manual regarding the operation method of the application that cannot be used, but if you actually read the instruction manual while operating the application, the digital TV receiver and the instruction manual at hand The eyes will come and go, and there may be a discrepancy between the instruction manual at hand and the TV screen.

  In order to improve usability, electronic instruction manuals (hereinafter electronic instructions) have appeared. An electronic manual is a manual that allows you to check how to use the application you want to use while operating the digital TV receiver. According to this electronic manual, since the usage method of the application that the digital television receiver itself wants to use can be investigated, the consistency between the instruction manual at hand and the television screen as described above can be obtained. Will never go back and forth.

As an example of a method for realizing the electronic instruction manual, there is a method related to plane control.
As one of the realizing methods, there is a method of displaying an explanation content by designating a URL (Uniform Resource Locator) using an HTML (Hypertext Markup Language) browser. This will be described with reference to FIG. FIG. 1 shows a configuration diagram of an example of a general digital television receiver. In the figure, in a scene where an application to be used is being operated, an “electronic instruction” button is pressed among various buttons on a remote controller (hereinafter referred to as remote controller) 101 by a user operation.

  The remote control signal of the code corresponding to the pressed button output from the remote control 101 by pressing this button is supplied to the key operation control unit 103 in the digital television receiver 100 through the user interface (U / I) 102, Here, after the content of the remote control signal is analyzed, the application control unit 104 is accessed to obtain the current application state in the digital television receiver 100.

Then, the application control unit 104 displays the description content to be displayed based on the acquired current application state (for example, an ID indicating a program guide display / non-display state, an electronic manual display / non-display state, etc.). An inquiry is made to the explanation content management table 105.
The explanation content management table 105 informs the browser 106 of the URL to the explanation content 107 consisting of a plurality of explanation content groups, and activates the browser 106 simultaneously.

  The browser 106 is an HTML browser, reads the explanation content in the explanation content 107 according to the display state of the current television screen, and the plane control unit 108 performs alpha blending (superimposition of a translucent image and another image). Are displayed on the screen by the screen display unit 109. At this time, the electronic manual is displayed on the moving image / still image switching plane. While the application is being used, the browser 106 is activated by a user operation from a state where it is not activated.

  Here, as a precondition for realizing the display of the electronic manual, when the “electronic manual” button is pressed by the user's operation of the remote controller 101, it is necessary to promptly display the explanation content. In addition, when the electronic manual is closed, it is necessary to return to the original application screen where the “electronic manual” button was pressed. (Each application screen is realized using still images, text figures, and subtitle planes. ing.).

  In view of the above, it is conceivable to realize an electronic manual by applying the conventional signal processing device described in Patent Document 1 that switches the plane to be displayed. The conventional signal processing apparatus described in Patent Document 1 uses a moving image / still image / text figure plane as a display destination of an image file read from an SD card or the like in order to make a slide show in a predetermined order smooth. The plane to be displayed is switched ".

Next, a configuration and operation when the conventional technique described in Patent Document 1 is applied to a digital television receiver will be described with reference to FIGS.
FIG. 30 shows a plane configuration of a plane displayed by a conventional digital television receiver. This plane configuration is an example in which all ARIB-defined plane configurations are provided by hardware. In FIG. 30, there are a moving image plane 201, a still image plane 202, a moving image / still image switching plane 203, a character graphic plane 204, and a subtitle plane 205. The moving image plane 201 is arranged at the lowest position. , The moving image / still image switching plane 203, the character graphic plane 204, and the subtitle plane 205 are arranged in this order.
The explanation content of the electronic manual is displayed on any one of the moving image plane 201, the still image plane 202, and the character graphic plane 204 fixed by hardware.

FIG. 31 is a flowchart for explaining content display processing in a conventional digital television receiver.
As an example, it is assumed that the application is in a running state. In this state, the user activates the electronic manual by first pressing the “electronic manual” button on the remote control 101 in FIG. 1 (step S11 in FIG. 31), thereby the explanatory content management table 105 in FIG. The browser 106 is activated at the same time as the URL to the explanation content 107 is transmitted to the browser 106 (step S12 in FIG. 31).

  Subsequently, the button of the remote control 101 that has been pressed is the second “electronic manual” button (the second press of the “electronic manual” button means the end of the electronic manual application). The key operation control unit 103 determines whether or not there is (step S13 in FIG. 31), and if the “electronic instruction” button is not pressed, the plane to be used (moving image / still image / text figure plane) is selected. (Step S14 in FIG. 31), it is determined whether or not the selected plane is unused (Step S15 in FIG. 31).

If the selected plane is not unused, the process returns to step S14 to select the plane to be used.
When the selected plane is unused, the browser 106 reads the content of the explanation content 107 (step S16 in FIG. 31), performs alpha blending by the plane control unit 108, and displays the selected plane on the screen display unit 109. (Step S17 in FIG. 31). In the case of an electronic manual, the explanation content is displayed on a selected plane among the moving picture plane 201, the still picture plane 202, and the character graphic plane 204. At this point, the display is not reflected on the screen.

  Subsequently, the contents of the plane displayed so far on the screen of the screen display unit 109 are cleared (step S18 in FIG. 31), and the plane to be displayed is switched and reflected on the screen (step S19 in FIG. 31). As a result, the screen is switched from the plain image that has been displayed so far to the selected plane among the moving image plane 201, the still image plane 202, and the character / graphic plane 204 from which the content has been newly read, and the electronic manual is displayed. Is done. Thereafter, the process returns to step S12.

  On the other hand, when it is determined that the button of the remote controller 101 pressed in step S13 is the “electronic manual” button pressed for the second time meaning the end of the electronic manual application, it is displayed before the browser is started. After returning to the original application screen (step S20 in FIG. 31), the display process of “electronic instruction manual” is ended (step S21 in FIG. 31).

  In addition, in order to display the content, there are few operation procedures that the user has to perform, and the content that can reduce the reading time at the time of page transition and the time until the display is completed is displayed without impairing the content. It is desirable.

  In Patent Document 2, an image with a small amount of data such as a thumbnail image or a compressed image is generated from original image data, displayed, and then read while the user is viewing the content. A method for improving the display speed by replacing and displaying is described.

JP 2003-219351 A JP 2006-221406 A

However, when the conventional technique described in Patent Document 1 is applied to a digital television receiver, there is a problem relating to plane switching means.
In other words, assuming that the ARIB-defined plane is provided by hardware, it may be necessary to deal with hardware in order to replace the plane provided by hardware as it is. In that case, if the conventional plane switching means is used, there is a problem that man-hours and development costs for modifying the hardware are generated, and there is a possibility that the plane cannot be switched as it is. .

  In the display method described in Patent Document 2, it is necessary to perform processing for generating thumbnail images. When displaying the content of a page with many images, many thumbnail images must be generated. It takes time until. In addition, although the display for one piece of content can be performed quickly, when there are a plurality of pieces of content, rereading of data occurs for each piece of content, and there is a problem that the operation waiting time of the user is generated at the time of page transition.

(First embodiment)
The configuration itself of the digital television receiver according to the first embodiment of the present invention is the same as the configuration shown in FIG. 1, and the configuration of the display plane is the same as that of FIG. Based on these configurations, an application display screen and a browser display screen installed in the digital television receiver are seamlessly connected according to the program for executing the flowchart of FIG. 2 in the configuration. Note that the display plane in the present embodiment provides all the plane configurations shown in FIG. 30 defined by the ARIB definition in hardware, and the plane configuration is not fixed by hardware. It is assumed that the explanation content is displayed on the moving image / still image switching planes 203 and 206.

Next, the operation of the first embodiment of the present invention will be described with reference to FIG. 1, FIG. 2, FIG. 3, and FIG.
FIG. 2 is a flowchart for explaining the display processing operation of the digital television receiver according to the first embodiment of the present invention.
First, a user operates the remote controller 101 in FIG. 1 to activate a desired application (step S101 in FIG. 2). Thereby, the activation of the desired application is completed (step S102 in FIG. 2). Subsequently, activation of the browser 106 in FIG. 1 is started (step S103 in FIG. 2). Note that blank content is displayed when the browser is activated.

  In this state, when an arbitrary button among various buttons on the remote controller 101 is pressed by a user operation, a remote control signal of a code corresponding to the pressed button is output from the remote controller 101, and the U / I 102 in FIG. Then, the contents of the remote control signal are analyzed by being supplied to the key operation control unit 103 in the digital television receiver 100, and it is monitored whether or not the button of the remote control 101 pressed here is an “electronic instruction” button ( Step S104 in FIG. Until it is determined that the “electronic instruction” button is pressed, the execution state of the application in step S102 is continued.

If the key operation control unit 103 determines that the “electronic instruction” button has been pressed, the key operation control unit 103 accesses the application control unit 104.
The application control unit 104 displays the description content 107 to be displayed based on the acquired current application state (for example, an ID indicating a program guide display / non-display state, an electronic manual display / non-display state, etc.). 1 is inquired of the content management table 105. The explanation content management table 105 transmits the URL to the explanation content 107 to the browser 106, and the browser 106 reads the content from the explanation content 107 (step S105 in FIG. 2).

Subsequently, the plane control unit 108 moves the moving image / still image switching plane 203 in the structure of the display plane shown in FIG. 30 to the uppermost plane as indicated by 206 in FIG. 3 (step S106 in FIG. 2).
At this time, the display of the plane other than the moving image / still image switching plane used by the current application is turned off, and the display of the moving image / still image switching plane 206 is turned on. As a result, the explanation content of the electronic manual is displayed on the screen display unit 109 by the moving image / still image switching plane 203.

That is, in FIG. 30, it is necessary to display the explanation content 107 and then return to the original application screen. Therefore, the moving image / still image switching plane 203 used to display the explanation content 107 is The arrangement of the character / figure plane 204 and the subtitle plane 205 is moved below the moving image / still image switching plane 203 by hardware. That is, as indicated by 206 in FIG. 3, the uppermost plane on the plane structure is changed from the caption plane 205 to the moving image / still image switching plane.
The principle is the same as when a personal computer is normally used and the window 2 completely overlaps the window 1, the lower window 1 appears not to be displayed.

Subsequently, until the key operation control unit 103 determines that the operated button on the remote control 101 is the second press of the “electronic instruction” button, the browser 106 displays between the explanation content and the explanation content. Transition is made (steps S107 and S108 in FIG. 2). For example, when the explanation contents on the first page cannot be fully explained, when the explanation is continued on the explanation contents on the second page, the above explanation contents are changed.
Further, there is a case where the focus is moved with the “up / down / left / right” button of the remote controller 101 in the explanation content, or a transition to another explanation content is made by pressing the “decision” button of the remote control 101 on the link. However, when it is determined that a button other than the “electronic instruction” button, for example, a “TV screen” button or a “specific application” button is pressed, the application is terminated (not shown in FIG. 2).

  If the key operation control unit 103 determines in step S108 that the “electronic instruction” button is pressed for the second time, the key operation control unit 103 determines that the electronic instruction application is to be terminated, and the plane control unit 108 determines that the electronic instruction application is terminated. As shown at 206, the moving image / still image switching plane at the highest position is moved to the original position indicated at 203 in FIG. 30 (step S109 in FIG. 2). At this time, the display of the moving image / still image switching plane 203 is turned off, and the display of the plane used by the application is turned on.

  Subsequently, the application control unit 104 puts the application into an execution state (step S110 in FIG. 2), and ends the display of the electronic instruction explanation content by the browser 106 (step S111 in FIG. 2). Note that the moving image / still image switching plane displays blank content but is not displayed on the screen.

  As described above, according to the present embodiment, when the application is executed by the application control unit 104, the browser 106 is kept activated (steps S102 and S103 in FIG. 2), and “electronic” is operated by operating the remote controller 101. When the “instruction” button is pressed, the URL to the content in accordance with the state of the currently displayed application is designated from the explanation content management table 105, and the explanation content 107 is displayed on the screen display unit 109 by the browser 106. Therefore, even if the content cannot be prefetched, the time until the content is displayed can be shortened compared to the conventional case.

In addition, according to the present embodiment, the moving image / still image switching plane used to draw the explanation content 107 by starting up the electronic manual application is displayed on the plane structure on the plane by hardware as indicated by 206 in FIG. After the upper plane is set (step S106 in FIG. 2), when the end of the electronic manual application is determined, the moving image / still image switching plane 206 is returned to the original position indicated by 203 in FIG. Since it is now returned to the application screen, there is no need to perform complicated plane control, and it takes almost no time to move the plane and display it on the screen, so the explanation content is displayed with little waiting time for the user. be able to.
Note that the time until display depends on the content creation. In the present embodiment, seamless transition from the application screen to the browser screen can also be realized.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
The configuration itself of the digital television receiver according to the second embodiment of the present invention is the same as the configuration shown in FIG. In addition, the configuration of the display plane is such that the plane provided by the hardware as shown in FIG. 32 by the conventional digital television receiver is a moving picture plane 1001, a still picture plane 1002, a main plane 1003, and an option plane 1004. In this embodiment, software plane technology is used, and instead of the main plane 1003 in FIG. 32, a browser plane 1005 and an application plane 1006 are created in a pseudo manner as shown in FIG.

  That is, in the present embodiment, unlike the first embodiment, the hardware does not provide all of the ARIB-defined plane configuration and is fixed to the plane configuration of FIG. 32 by hardware. The provided main plane 1003 is divided into a browser plane 1005 and an application plane 1006 using a software plane technique, and is characterized in that an ARIB-defined plane configuration is realized in a pseudo manner.

Next, the operation of the second embodiment of the present invention will be described with reference to FIG. 1, FIG. 4, FIG. 5 and FIG.
FIG. 4 is a flowchart for explaining the display processing operation of the digital television receiver according to the second embodiment of the present invention.
First, when the user operates the remote controller 101 in FIG. 1, the application control unit 104 activates a desired application (step S201 in FIG. 4). At this time, the still image plane 1002 and the application plane 1006 shown in FIG. 5 are used, and these displays are turned on. Thereby, the activation of the desired application is completed (step S202 in FIG. 4). Subsequently, activation of the browser 106 in FIG. 1 is started (step S203 in FIG. 4). The plane used at this time is the browser plane 1005 shown in FIG. 5, and the display is turned off.
Note that blank content is displayed when the browser is activated.

  In this state, when an arbitrary button among various buttons on the remote controller 101 is pressed by a user operation, a remote control signal of a code corresponding to the pressed button is output from the remote controller 101, and the U / I 102 in FIG. Then, the contents of the remote control signal are analyzed by being supplied to the key operation control unit 103 in the digital television receiver 100, and it is monitored whether or not the button of the remote control 101 pressed here is an “electronic instruction” button ( Step S204 in FIG. 4). Until it is determined that the “electronic instruction” button is pressed, the execution state of the application in step S202 is continued.

  If the key operation control unit 103 determines that the “electronic instruction” button has been pressed, the key operation control unit 103 accesses the application control unit 104. The application control unit 104 displays the description content 107 to be displayed based on the acquired current application state (for example, an ID indicating a program guide display / non-display state, an electronic manual display / non-display state, etc.). 1 is inquired of the content management table 105. The explanation content management table 105 transmits the URL to the explanation content 107 to the browser 106, and the browser 106 reads the explanation content of the electronic manual from the explanation content 107 (step S205 in FIG. 4).

Subsequently, the plane control unit 108 moves the browser plane 1005 in the structure of the display plane shown in FIG. 5 to the uppermost plane as indicated by 1010 in FIG. 6 (step S206 in FIG. 4). At this time, the display of the application plane 1006 in FIG. 6 is turned off, and the display of the browser plane 1010 is turned on.
Thereby, the explanation content of the electronic manual read in step S205 is displayed on the screen of the screen display unit 109 by the browser plane 1010.

  Next, the key operation control unit 103 continues between the explanation content and the explanation content displayed by the browser 106 until it determines that the operated button on the remote controller 101 is the second press of the “electronic instruction” button. Transition is made (steps S207 and S208 in FIG. 4). However, when it is determined that a button other than the “electronic instruction” button, for example, a “TV screen” button, a “specific application” button, or the like is pressed, both the application and the explanation content are terminated (not shown in FIG. 4). ).

  If the key operation control unit 103 determines in step S208 that the “electronic instruction” button has been pressed for the second time, the key operation control unit 103 determines that the electronic instruction has ended, and moves to the highest position as indicated by 1010 in FIG.

In FIG. 13, in the explanation content display state of the electronic manual, first, when the “return” button is pressed by the operation of the remote controller 101 by the user (step S <b> 901), the U / I unit 102 is transmitted from the remote controller 101. The key code of the “return” button is received and notified to the key operation control unit 103 (step S902), and the key code is further notified to the application control unit 104 (step S903).

  At this time, if the URL of the explanation content currently being displayed is the same as the URL of the explanation content displayed first, the plane control unit 108 notifies the highest position shown in FIG. The browser plane 1010 is moved to the original position indicated by 1005 in FIG. 5 (step S904). Then, the plane control unit 108 turns off the display of the browser plane 1005 (step S905), and turns on the display of the plane used by the application (step S906). Thereby, the screen display unit 109 displays the original application (step S907). As described above, when the “return” button is pressed while the explanation content from the same URL as the explanation content displayed first is displayed, the original application is displayed.

  On the other hand, when the URL of the explanation content currently displayed at the time of step S903 is not the same as the URL of the explanation content displayed first, the application control unit 104 notifies the browser 106 of a “return” button input. (Step S908). As a result, the browser 106 causes the screen display unit 109 to display the URL explanation content displayed one page before (step S909). As described above, when the “return” button is pressed while displaying the explanation content from the URL that is not the same as the URL of the explanation content displayed first, the explanation content returns to the previous page.

Next, a sixth embodiment of the present invention will be described.
This example is an example when the “TV screen” button is pressed as a sequence related to the end of the electronic manual in the example of the second embodiment.
This embodiment will be described with reference to the sequence diagram of FIG.
In the figure, the same components as those in FIG.
In FIG. 14, when the “TV screen” button is pressed by the operation of the remote controller 101 by the user in the electronic instruction explanation content display state (step S <b> 1001), the U / I unit 102 is transmitted from the remote controller 101. The key code of the “TV screen” button is received and notified to the key operation control unit 103 (step S1002).

  When the notified key code is for the “TV screen” button, the key code control unit 103 notifies the application control unit 104 to end the application (step S1003). Accordingly, the application control unit 104 ends the browser 106 (step S1004).

  Subsequently, the application control unit 104 causes the plane control unit 108 to move the browser plane 1010 at the highest position shown in FIG. 6 to the original position 1005 shown in FIG. 5 (step S1005), and further in FIG. The display of the browser plane 1005 is turned off (step S1006), and the display of the application plane 1006 of FIG. 5 used by the application is turned off (step S1007).

  Thereby, the screen display unit 109 displays an image (on-air screen) of a television program that is selected and received by the digital television receiver (step S1008). In this way, when the “TV screen” button is pressed during the display of the electronic instruction explanation content, the on-air screen is displayed.

In the above-described embodiments and examples, the electronic manual implementation method has been described as an example of plane control. However, the present invention is not limited to the above-described embodiments and examples. It can also be used to execute an application installed in a digital television receiver using a plane configuration other than the ARIB definition.
In addition, when switching between the application screen and the browser screen, seamlessness can be realized.

  Next, the digital TV receiver has a memory with a smaller capacity than the memory installed in the personal computer and the browser is installed. An embodiment capable of reducing time will be described.

A third embodiment will be described in which a browser plane is selected from the plurality of planes described above, and content data is displayed in a short time using the browser plane.
(Third embodiment)
A third embodiment of the present invention will be described with reference to FIG.
The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.
As shown in FIG. 15, the digital television receiver 110 in the third embodiment of the present invention is to display instead of the explanation content 107 in the digital television receiver 100 in the first embodiment shown in FIG. A flash memory 111 storing content data in advance and a buffer memory 112 having a content browsing program and temporarily storing the content data stored in the flash memory 111. Is the same.
Here, the explanation content management table 105 has a function of notifying the browser 106 of the URL to the flash memory 111 and reading the content data stored in the flash memory 111 into the buffer memory 112. The browser 106 has a function of reading content data from the buffer memory 112. The buffer memory 112 is much faster than the reading and reading speed of the flash memory 107.

Next, the operation of the third embodiment of the present invention will be described with reference to FIG. 5, FIG. 6, FIG. 15, and FIG.
First, steps similar to steps S201 to S204 in the second embodiment are performed.
(Step S1101)
Next, as illustrated in FIG. 16, when it is determined that the “electronic instruction” button has been pressed, the key operation control unit 103 accesses the application control unit 104. The application control unit 104 displays the display in the flash memory 111 based on the acquired current application state (for example, an ID indicating a program guide display / non-display state, an electronic manual display / non-display state, etc.). The content management table 105 is inquired about the content data to be executed.
The content management table 105 acquires the first page A of the content data in the flash memory 111 based on the content browsing program stored in the buffer memory 112, and reads the page A into the buffer memory 112. Include.

(Step S1102)
Next, the plane control unit 108 moves the browser plane 1005 in the structure of the display plane shown in FIG. 5 to the uppermost plane as indicated by 1010 in FIG.
At this time, the display of the application plane 1006 in FIG. 6 is turned off, and the display of the browser plane 1010 is turned on.

(Step S1103)
Next, it is determined whether or not an image file is used in page A read into the buffer memory 112.

(Step S1104)
If no image file is used in page A, the process is terminated through steps S208 to S211 in FIG. 4. If an image file is used, an image that may not be visible from the beginning is Keep hidden.
However, when an image file is used for the page A displayed at the beginning of the acquired content, all the original data is set to be displayed.
The image that does not need to be seen is an image of each page on and after the next page of page A that uses the acquired content data image file.

(Step S1105)
The image of each page after the next page of page A is set to non-display under the control of the explanation content management table 105 and read from the flash memory 111, and the image data of each page after the next page of page A is read. Is replaced with an image having a smaller data amount than the original image to be displayed and read into the buffer memory 112.

(Step S1106)
Next, the reading of the image data with a small amount of the above data into the buffer memory 112, which is replaced in place of the image of each page on and after the next page of the A page using the image file of the acquired content, After all pages from the next page of A are completed, the first page A data is read from the buffer memory 112 using the browser 106 and displayed on the screen display unit 109. The image data of each page is read again from the flash memory 111 and read into the buffer memory 112 with the original data amount.
At this time, the image of the first page A is displayed on the screen display unit 109.

(Step S1107)
Next, after the reading of the image with the original data amount into the buffer memory 112 is completed in step S1106, the next page of the A page is not required to display the image with the original data amount on the screen display unit 109. The original image of each subsequent page is hidden.

(Step S1108)
Next, when the user designates an arbitrary page on and after the next page of page A, the image of the designated page is switched from non-display to display, read from the buffer memory 112, and displayed on the screen display unit 109.
At this time, the image of the first page A is switched from display to non-display.
(Step S1109)
Next, when the key operation control unit 103 determines that the “electronic instruction” button is pressed for the second time, the same operation as that in steps S208 to S211 of FIG.

As described above, in the present embodiment, when the content is read, only the necessary sentences on the first page are read, and other images after the next page of the first page A that do not need to be displayed immediately. Are replaced with an image having a small data amount and read (steps S1101 to S1105). FIG. 17A shows an example in which the image of the next page (2 sheets) is replaced with an image with a small data amount (for example, a very small transmission image). FIG. 17B shows an example of a display screen when the left two images in FIG. 17A are read as small images.
The display image of the large area on the right side of the display screen is an image with an original data amount (for example, the first page A) before the image of the next page replaced with an image with a small data amount. is there.

Once the display of the content is completed, while the user is viewing the items (pages) that have already been displayed, the images with the smaller data are assigned to the original ones in order from the related items (pages). It is replaced and read (steps S1106 and S1107), and is displayed when the user tries to view another item (page) (step S1108). Hide images that no longer need to be displayed so they are not visible. The “relevant item” is an item that is likely to be viewed next by the user because the button is closely related to the contents of the content.
This also applies to content that can be accessed directly. An example showing the depth of the relationship between contents is shown in FIG.

FIG. 18A shows a display screen of the digital television receiver when the A button is focused and the opened content is the A page. In this case, as shown in FIG. 18 (B), the C button is close to the A button and may be immediately focused. Therefore, the C button is related, and as shown in FIG. The next button in is expected to be linked to the content that continues, and it is highly likely that it will be referenced next.
Therefore, when the A button has focus and the A page is open, the contents of the B and C pages and the contents of the next page are preferentially read.

  In the present embodiment, all pages displayed at the beginning of content are set to display original image data. The image data of the other pages of the content is replaced with data with a small amount of data and is hidden so that the data of all pages of the apparent content is read and then the image data of the first page is displayed. . The content reading method of this embodiment is schematically shown in “Replace and read” in FIG.

  In the present embodiment, all the image data of pages other than the first page A of the content is composed of data with a small amount of data. Therefore, FIG. 17C schematically shows “read all data at once”. Compared with the reading method in which the first page is displayed after reading all the data of all the pages of the content shown in the present embodiment, the time until the display of the first page is completed is shorter. In addition, in this embodiment, the reading time experienced by the user can be shortened compared to the method of alternately reading and displaying each page, which is schematically shown as “reading only one page” in FIG. .

  In the present embodiment, the image data of pages other than the first page A of the content is converted into a buffer in the digital television receiver during the display period displayed on the screen display unit 109. Since the data stored in the memory 112 is then read out as needed, there is an advantage that display switching between pages can be performed at a higher speed than when the page is read again.

  In the present embodiment, after displaying the first page A of the content, the original data is replaced with one having a smaller amount of data in order from the page closely related to the first page A of the content. The reason for reading from the page that is closely related to the first page of the content is that the user is likely to open it as the page of the content to be viewed next. Since these operations are performed while the user is viewing the first displayed content page, the content of the next page can be displayed without the user feeling a waiting time. When the user tries to view another page of the content, the user simply switches the currently displayed content page from display to non-display and switches the content page to be displayed from non-display to display.

  By doing so, it is not necessary to read data again when viewing another page, and it is possible to move between pages at high speed. As an example of means that can actually realize such movement, a case where a digital television receiver equipped with a browser, JavaScript, and CSS (Cascading Style Sheets) is used (java is a registered trademark; the same applies hereinafter) is shown. When JavaScript is used, HTML content can be dynamically operated and interactively operated, and is currently supported by most browsers.

  In this embodiment, it is used for the operation when HTML is first read and for the transition between pages. Also, CSS can align the document format. When you want to arrange several documents in the same style, you can set the formats that are used repeatedly in this way by grouping them together in the CSS. This is called a class. In recent years, it has been widely used because the appearance of content contents can be unified by referring to the same class. In the class, text color, background color, etc. can be set as attributes.

  CSS (Cascading Style Sheets) attributes used in this embodiment are visibility (display attribute that can be set to display or not) and background image (background-image; background in a specified area) Attribute used when specifying the image file to be used). If you set the visibility attribute, you can specify whether or not to display an image that refers to the class. For the image to be displayed first, the visibility is set to “possible”. By making this visible, it is specified to display an image. For images that do not need to be displayed first, when specifying a background image (background-image), make sure that an image with a small amount of data is read first, and set the display attribute to hidden. Set it.

  By doing so, it is specified not to display an image. In the HTML content that is read first, an image with a small amount of data other than the image that is desired to be displayed from the beginning is read. Therefore, all the images are displayed on one piece of content until the display is completed. It is shorter than the time (see FIG. 17C). By using the JavaScript function, it is possible to change the CSS attribute value once read. In the present embodiment, when viewing another image, the visibility of the image that has been viewed so far is switched from visible (display) to hidden (non-display) and hidden. Then, the image that has been hidden (hidden) until now is set to be visible (displayed).

In addition, CSS attributes that can be changed by JavaScript can change not only the display / non-display of images but also the background image attributes that refer to image files. An image with a small amount of data is designated as a background image for an image that is not displayed in the initial state, and display of HTML content is completed once. While the user is looking at the first read item, the address of the original image is changed in order from the closely related item. A closely related item refers to an item that may be referenced immediately from the first loaded item.
For example, it is a continuation item after the first read item (see FIG. 18). The reason for reading from items that are closely related is that the user is more likely to browse next than other items, and therefore, it is considered that an image is required earlier than other items. After changing to the address of the original image, the image is not visible to the user, but is read, and when the visibility is changed to “possible” (display), the image originally desired to be displayed is displayed. When this method is used, only the display / non-display switching of the image is required as compared with the case of displaying the image separately for each page, so that the time until the display is completed is shortened.

  According to the present embodiment, even if the content displayed on the page changes, the HTML content is created as a single HTML, so the HTML content is not reloaded and the user waits until the display is completed. Time can be reduced. Further, according to the present embodiment, an image that has been read once can be displayed only by switching the visibility (possible) or hidden (non-display) from the next use. For this reason, once an image is displayed, no reading time is generated, so that the movement between pages can be performed lightly.

FIG. 19 shows a diagram in which the menu screen in the present embodiment is realized using a large image and HTML.
The rectangular small area images A, B, C, D, and E on the left side of the screen shown in FIGS. 19B to 19C are images showing buttons. By pressing these buttons, The page content corresponding to the selected button is displayed on the large area screen portion on the right side of the screen.
For example, page A is displayed when the A button is pressed, and page B is displayed when the B button is pressed. As a result, although it looks 5 pages, it can actually be created with a single HTML, and the transition between pages is just to switch the visibility of the image, so each page is created and linked to I can do it quickly.

That is, when the three pages A1, B2, and C2 of one content shown in FIG. 19A are selected and displayed, first, as shown in FIG. It is assumed that page A is opened and the A button is focused. As a result, as shown in FIG. 19B, in the class that is read when the page is displayed, the background image attribute is set to the image A1, and the visibility is set to displayable (possible). Is displayed.
In the following, visibility is indicated for solid lines in the figure, and visibility is not displayed for dotted lines (hidden). In the initial state shown in FIG. 19B, the image used in the other page B is an image B1 having a small amount of data as a background image attribute, the visibility is set to be non-displayable, and the image is not displayed. It has become. The same applies to the image C1 used in the page C.

  While the user is viewing page A which is the first display state, images of page B and page C, which are items that are likely to be viewed by user from page A, are displayed as background images in this embodiment. Replace and read the original image. Here, the reason why the relevance is judged to be high is that the items above and below the button A are the button B and the button C. Since these focus movements from the button A are short, page B or page C This is because there is a possibility that it will be referred to sooner than D or page E.

When the images of page B and page C are read, the images of page D and page E are replaced and read in the same manner.
When the user presses the B button to view another page, the visibility of the image A1, which is the background image of the currently displayed page A, is set to be non-displayable so that the background image of the page B is not visible. The visibility of the original image set to “1” is changed to displayable (FIG. 19C). In this example, the button placed on the left side of the screen is pressed to display the next page, but an onclick function is used as one means for detecting that the button has been pressed. How to use is listed.

As shown in FIG. 19C, when the focus moves from the A button to the B button and it is detected that the button is clicked, the visibility of the displayed image A1 is disabled, and the image B1 is displayed. When the visibility is changed to displayable, the screen of the image B2 is displayed on the front.
In page B, page D and page A are thought to be closely related from the position of the button, but since page A has already been displayed, it is not read again. Page D is read if it has not been read while page A is displayed.

Similarly, in the display state shown in FIG. 19B, when the user presses the C button to view another page, the visibility of the image A1, which is the background image of the currently displayed page A, cannot be displayed. The visibility of the original image set as the background image of page C is changed to displayable and displayed. That is, as shown in FIG. 19D, when the focus is moved from the A button to the C button and the click is detected, the visibility of the displayed image A1 is disabled and the image is displayed. When the visibility of C2 is changed to displayable, the screen of the image C2 is displayed on the front.
In page C, it is assumed that page E and page A are closely related from the position of the button, but page A has already been displayed, so it is not read again. Page E is read if it has not been read while page A is displayed.

FIG. 20 is a sequence diagram simply showing the operation of the present embodiment.
In the example of FIG. 19, there are a total of 5 pages of content to be displayed, but in FIG. 20, the description will be made assuming that the number of pages is 3 for easy understanding. Pages B ′ and C ′ are pages obtained by replacing page B and page C with images having a data amount smaller than the data amount.

In FIG. 20, when the user first issues an instruction to display the first page A of content (step S21), the page A data is first read into the buffer memory 112 (step S22), and then the data with the next smallest amount of data. The data of page B ′ and page C ′ replaced with is temporarily read into the buffer memory 112 together without being displayed (steps S23 and S24). Only page A is displayed.
Here, since the content is composed of 3 pages in total, the reading of the first page A of the content is completed by reading the data of a total of 3 pages, pages A, B ′, and C ′, into the buffer memory 112 (step S25). ).

  Here, the time required to complete the reading of page A requires time to complete the reading of other pages B and C, but in this embodiment, the data is replaced with data with a small amount of data. Since page B 'and page C' are apparently read as page B and page C, reading of page A is completed in a shorter time than conventional.

Subsequently, although it seems that the display of page 3 is completed once, the original page B and page C data is read into the buffer memory 112 while the user is displaying page A (step S26, S27). Thereafter, when the user switches the page from page A to page B (step S28), the page displayed on the display unit is switched from A to B (step S29), and the display of page B is completed (step S29). Step S30).
As described above, in the present embodiment, it is only necessary to switch between display and non-display of the page, so that the user does not have time to reload the page, and the page transition can be performed quickly.

FIG. 21 shows a display screen of an embodiment applied to an exhibition guide menu or the like.
With the image shown in FIG. 21A as an initial screen, the screen is switched when a predetermined time elapses or the next button on the initial screen is pressed, and page A, which is the next page shown in FIG. 21B, is opened. While the user is viewing page A, page B is displayed when the B button is pressed, page C is displayed when the C button is pressed, and then the next button is pressed or time passes. The page contents are read with the page to be displayed as a deeply related item.

  After preferentially reading the data of the next page of page B, page C, and page A, the data of page D and page E are read. FIG. 21C shows a display screen when moving to page B, and FIG. 21D shows a display screen when moving to page C. In FIGS. 21C and 21D, the screen of page A is hidden and the screens of page B and page C are displayed on the front as shown by the dotted lines. Then, the data of the next page that seems to be closely related to page B and page C is read. If page D data has not been read while page A is open, page D data is also read preferentially. The B button and the C button are buttons next to the A button. However, since the page A is first activated and displayed, data remains in the flash memory 111 and is not read again.

Next, the effects expected when the third embodiment is actually applied to content will be described with specific numerical values.
The size per content (one page) that can be replaced with a small image is 80 kB. Further, it is assumed that there is 200 kB of minimum data that does not cause replacement. Furthermore, the size of an image with a small data amount set first is 1 kB. The total data amount is shown on the assumption that the number of content pages is 5 (5 pages).

(1) When this embodiment is not applied and data of all pages of content is first read 200 kB + 80 kB × 5 sheets = 600 kB
(2) When this embodiment is not applied, only the first page of content is read, and the second and subsequent pages are read in page units 200 kB + 80 kB × 1 sheet = 280 KB
(3) In the case of this embodiment 200 kB + 80 kB × 1 sheet + 1 kB × 4 sheets = 284 KB
If these contents are viewed on a device with a line speed of 600 KB per second, the time required is 1 second (= 600 KB ÷ 600 KB) when all data is read first without applying this embodiment. When this embodiment is not applied and only the first page is read and then read each time, it is 0.466 seconds (= 280 kB ÷ 600 kB; however, the reading time occurs when other pages are moved). On the other hand, according to the present embodiment, it becomes 0.473 seconds (= 284 kB ÷ 600 kB; reading of other pages is not experienced by the user), and the reading time is reduced to less than half of the data reading of all pages. In addition, it is clear that there is an effect of shortening the waiting time of the user because no waiting time is generated when the page in the content is moved.

  As described above, according to the present embodiment, when viewing a content such as a menu or help with many items on a device having a small memory capacity for screen display, only the necessary images among the content images are first displayed. Display and replace other images with ones with a small amount of data, and use them by reading and replacing items that are closely related to the current content while the user is viewing the content image. Compared to displaying all the images etc. all at once, the time to display can be shortened and the display switching between pages can be performed at high speed. Convenience when browsing content can be improved.

  Next, as in the third embodiment, the memory having a smaller capacity than the memory installed in the personal computer, the browser installed, and the contents stored in the flash memory 111 are displayed. Instead, a digital television receiver that displays content such as images and sounds acquired from a server via a network such as the Internet will be described.

(Fourth embodiment)
The same components as those in FIG. 1 and FIG.
As shown in FIG. 22, the digital television receiver 113 according to the fourth embodiment of the present invention uses a content file type instead of the flash memory 111 of the digital television receiver 110 according to the third embodiment. A data holding unit 114 for storing files of corresponding images (for example, sound, images, moving images, etc.) and a memory 115 for storing original data obtained from the server 116 via the network; Other than that, the same applies.
In the following, it is assumed that the content is described in HTML.

  The content browsing program stored in the buffer memory 112 reads the content page A on the server 116 connected via the Internet.

  In this embodiment, when a content is read and there is a multimedia file such as an image, the data recorded in the data holding unit 114 in the digital broadcast receiver (main body) is replaced with the image. Display. As an example of data recorded in the data holding unit 114 in the main body, an icon having a data amount smaller than an image to be originally displayed so that the type of data can be seen at a glance. At this time, it is assumed that the icons to be displayed are held in the data holding unit 114 in several types so as to be changed according to the original file type as will be described later.

  In this embodiment, an image on the Internet or the like is not read and an image is not generated, and display is performed using data recorded in the data holding unit 114, thereby displaying the image at a high speed and further displaying the image. In the meantime, the original multimedia data is read. If it is necessary to display it, display it after replacing the data. As an example of means for realizing such movement easily and visually, in the present embodiment, in this embodiment, a digital broadcast receiver 113 equipped with a browser 106 and HTML content built in the main body thereof. And a case where it is realized by JavaScript.

  When JavaScript is used, HTML content can be dynamically operated and interactively operated, and is currently supported by most browsers. In the present embodiment, as an example of processing performed after an image in the main body is displayed first and the image is read, as shown in FIG. 23A, the HTML file to be displayed is called image_load () in Java Script. Suppose you have a function that reads the original image. The original image is assumed to be placed on a server (116 in FIG. 22) connected to the Internet.

  When an image is put on HTML content and described as <IMG-onLoad = “processing”>, the processing described in onLoad is performed when the image is read. When a JavaScript function, image_load () as shown in FIG. 23B is inserted, the original image is displayed after the reading of the image recorded in the main body is completed (see FIG. 23C). The original content to be read and displayed can be displayed (see FIG. 23D).

Next, the operation of the fourth embodiment of the present invention will be described with reference to FIG. 22, FIG. 24 and FIG.
In FIG. 25, the right half of the figure shows the movement of the browsing program, and the left half shows the display function.
Here, a case where the icon 114A is used will be described as an example of a small amount of data and high visibility.

First, steps similar to steps S201 to S204 in the second embodiment are performed.
(Step S1201)
Next, as shown in FIG. 24, when it is determined that the “electronic instruction” button has been pressed, the key operation control unit 103 accesses the application control unit 104. The application control unit 104 displays the current application state in the server 116 based on the acquired current application state (for example, an ID indicating a program guide display / non-display state or an electronic manual display / non-display state). The content data management table 105 is inquired about content data.
The content management table 105 reads the original page A of the content data on the server 116 to the buffer memory 112 via the network by the browser 106 based on the content browsing program stored in the buffer memory 112. .

(Step S1202)
Next, the plane control unit 108 moves the browser plane 1005 in the structure of the display plane shown in FIG. 5 to the uppermost plane as indicated by 1010 in FIG. At this time, the display of the application plane 1006 in FIG. 6 is turned off, and the display of the browser plane 1010 is turned on.

(Step S1203)
Subsequently, it is determined whether or not the read page A uses a multimedia file such as an image. If not, the page A is displayed (step S1210), and the process is performed through steps S208 to S211 in FIG. Exit.

(Step S1204)
If a multimedia file is used, an address (reference address) is temporarily stored in the buffer memory 112 from a location referring to the multimedia file. For example, in the case of HTML, if there is a reference to a multimedia file such as <IMG src = “... >><embed src =“ file: //...> ”, The buffer memory 112 stores the referenced address. Save in.
As shown in FIG. 25, the buffer memory 112 stores a file name (Filename) of a multimedia file to be read.

(Step S1205)
Subsequently, from the extension or file name of the reference address stored in the buffer memory 112, it is determined what type (image, sound, etc.) the multimedia file is.
FIG. 26 shows an example specifically showing the relationship between the determined file type and the corresponding icon. FIGS. 26A to 26C show icons created using JPEG images, WAV audio, and MPEG moving images as examples. The icons 114A in FIGS. 26D to 26F are icons used in the example of FIG. 29 to be described later. As shown in FIG. 26, what type of file is present at once by the user. Use something that understands.

  Although not shown in FIG. 26, a user who does not have knowledge of the extension or the like as used in other drawings even if the icon is not divided by the extension or the like of the linked file. There is also a method of dividing and indicating with icons so that it can be understood that there is data such as images, video and audio even if it is viewed. The above icons are stored in advance in the data holding unit 114 in the main body.

(Step S1206)
Returning to FIG. 24 and FIG. 25 again, description will be given.
The browsing program stored in the buffer memory 112 selects an icon of a type corresponding to the determined multimedia file from the icons 114A stored in the data holding unit 114 in the main body of FIG. 22, and the selected icon The page B generated based on 114A is replaced with a multimedia file.

(Step S1207)
Next, the page B of the replaced icon is displayed on the screen display unit 109 while the display of the browser plane 1010 is on.

(Step S1208)
Subsequently, after the display of page B is completed, the multimedia file is read from the server 116 with reference to the address stored in the buffer memory 112 and stored in the memory 115.

(Step S1209) and (Step S1210)
When the reading is completed, the original multimedia file is replaced with the image of page A and displayed on the screen display unit 109. If the referenced file cannot be read for some reason at this time, or there is no data to be read, it will not be replaced.

(Step S1211)
Next, when the key operation control unit 103 determines that the “electronic instruction” button is pressed for the second time, the same operation as that in steps S208 to S211 of FIG.

FIG. 27 is a sequence diagram for explaining the operation of the present embodiment described in conjunction with FIG. 24 and FIG.
In FIG. 27, when the user issues a display request for page A (step S1301-1), the display request is displayed on the screen display unit 109, and the browsing program stored in the buffer memory 112 is the data for page A. Is acquired by the server 116 via the network (step S1302). Thereby, the browsing program acquires the data of page A from the server 116 via the network (step S1303), and stores the reference address for the multimedia file from the acquired data in the buffer memory 112 (112 in FIG. 22). (Step S1304), the icon is changed to the icon in the data holding unit 114 in the main body according to the file type (Step S1305), and the page B in which the icon is referred to is configured (Step S1306).

  Next, the browsing program stored in the buffer memory 112 displays the state of page B on the screen display unit 109 (step S1307-1). When the display of page B on the screen display unit 109 is completed (step S1307-2), the browsing program goes to acquire original data from the server 116 based on the reference address in the buffer memory 112 (step S1308). When the original data is acquired from the server 116 via the network (step S1309), it is stored in the memory 115 (FIG. 22), and then the display of the screen display unit 109 is changed from the state in which the main body icon is displayed. Page A on which an image based on the original data from 115 is displayed is reproduced (steps S1310 and S1311).

  As described above, according to the fourth embodiment, when displaying a page of content using a multimedia file such as an image, data recorded in the main body data holding unit 114 (for example, data (Such as icons that can be seen at a glance) for each file type, read the original data while the data is displayed, and display or play it when necessary. Therefore, it is possible to reduce the time required for reading content and the time required for page transition, and the convenience of the user in the function can be improved.

  In addition, by doing this, it is possible to avoid the problem that no image is displayed even if the display of the page cannot be completed due to insufficient capacity of the buffer memory 112. Since these operations are performed while the user is looking at the displayed page, the reading of all data can be completed without the user feeling a waiting time.

Next, the effects expected when the present embodiment is actually applied to content will be described with specific numerical values.
The size per multimedia file that can be replaced with an icon in the main body is 80 kB. Further, it is assumed that there is 200 kB of minimum data that does not cause replacement. Furthermore, the icon size in the main body with a small amount of data set first is assumed to be 1 kB. Also assume that there are five linked multimedia files.

  As shown in FIG. 28 (A), the present embodiment is not applied, and the total data amount when first reading all the data of the multimedia file is 600 kB (= 200 kB + 80 kB × 5). When these contents are displayed on a device with 600 kB per second, the waiting time required to complete the display is 1 second (= 600 kB ÷ 600 kB).

  On the other hand, as shown in FIG. 28B, in this embodiment in which an image in the main body is first read and then the original image is read and sequentially displayed, the amount of data to be read is 284 kB (= 200 kB + 80 kB × 1). Therefore, when these contents are displayed on a device with a line speed of 600 kB per second, the waiting time until display completion is 0.473 seconds (= 284 kB ÷ 600 kB).

  Therefore, compared with the case of the conventional method shown in FIG. 28A in which the user waiting time is schematically indicated by A in FIG. 28C, the user waiting time is schematically indicated by B in FIG. It is clear that the present embodiment of FIG. 5B has the effect that the reading of other pages is not experienced by the user and that the reading time is shortened to half or less of the total data reading time.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
In the fifth embodiment, in order to further expand the function of steps S1208 to S1210 in FIG. 24 of the fourth embodiment and cope with errors, the data holding unit 114 displays an error. An icon is also prepared.

Next, the operation of the present embodiment will be described with reference to FIG.
In the figure, the same processing steps as those in FIG. 24 are denoted by the same reference numerals, and the description thereof is omitted.
(Step S1212)
After performing steps S1201 to S1207 in FIG. 24, the original multimedia file data on the server 116 is acquired.

(Step S1213)
Next, it is determined whether or not the data of the multimedia file can be displayed.
(Step S1208)
When the data of the multimedia file can be displayed (when the data can be acquired), the original data is replaced. This is the same as in the fourth embodiment.

(Step S1214)
On the other hand, in this embodiment, when it is determined in step S1213 that the browsing program stored in the buffer memory 112 cannot acquire the multimedia file for some reason, the browsing program is returned. Determine the type of error.

(Step S1215)
Then, the icon 114A in the data holding unit 114 in the main body corresponding to the determined error is replaced with the image displaying the page B and displayed on the screen display unit 109.
(Step S1210)
Thereafter, page A in which the address of the reference image is changed is displayed. This is the same as in the fourth embodiment.
(Step S1211)
Next, when the key operation control unit 103 determines that the “electronic instruction” button is pressed for the second time, the same operation as that in steps S208 to S211 of FIG.

  Accordingly, in the present embodiment, even if the multimedia file cannot be displayed, the reason why the multimedia file cannot be displayed to the user can be indicated by the icon 114A, and the problem that no image is displayed can be prevented. .

  The present invention is not limited to the above embodiment, and for example, the present invention can be applied to an electronic device equipped with a browser other than a digital broadcast receiver.
