Abstract

PROBLEM TO BE SOLVED: To solve the problem that even when storable cache data quantity changes due to the change of screen layout such as full screen display and two screen display, the disposal of data is executed in accordance with a priority order determined on the basis of a final use time or the restoration time of a compressed image in the current cache data, and the disposal of cache data corresponding to the change of the screen layout is not executed in a conventional technology.SOLUTION: The electronic equipment includes a function for executing the selective storage/disposal of a cache corresponding to screen layout by using a cache rule for determining the cache priority order of information (in-screen information) to be displayed in a screen in accordance with the screen layout.

Description

  The present invention relates to a technology for suitably caching in-screen information displayed in a screen according to a screen layout in a memory.

  Currently, GUIs (graphical user interfaces) for executing various functions are provided in electronic devices such as televisions. Examples of such a GUI include an electronic program guide for making a recording / viewing reservation, a selection screen for content (such as a movie) distributed on demand from a server device on the Internet, and the like. In such a GUI, for example, in-screen information such as program text information to be displayed in each program column of the electronic program guide and thumbnail images for selection of on-demand distribution content is held in a memory as a cache and can be reused. It is configured.

  By the way, the storage capacity of the memory in which in-screen information (program text information, thumbnail images, etc.) used for the GUI is cached is finite. Therefore, in these electronic devices, for example, the cache data in the memory is used last. The configuration is such that the recorded time is discarded in ascending order. Patent Document 1 discloses a technique for determining an image to be discarded (replaced) in consideration of a decompression time of a compressed image that is cache data, not in order of last use time.

  However, the above prior art has the following problems. That is, in an electronic device capable of screen display, the screen display can be performed in various screen layouts such as full-screen display, two-screen display, and picture-in-picture (PinP) display. Of course, when displaying only the GUI as described above, for example when displaying only the GUI as described above, and when displaying the GUI and content separately by two-screen display or PinP display, for example, the latter naturally displays a larger amount of information. Also, the amount of memory used increases. That is, the memory area that can be used to hold cache data is reduced accordingly.

  However, in the above prior art, even if the amount of cache data that can be held changes due to the change in the screen layout in this way, it is determined from the data currently cached based on the last use time, the compressed image restoration time, etc. There is a problem that the data is discarded according to the priority order, and the cache data is not discarded according to the change of the screen layout.

In the first embodiment, claims 1 to 9 will be mainly described.

Example 1
<Overview>
FIGS. 1A and 1B are diagrams for explaining an example of priority determination such as discarding of cache data according to the present embodiment. As shown in FIG. 1A, icon images A1, A2, A3 and text information A4 are displayed in the GUI screen (first page) of “full screen display”. These data A1 to A4 are held as a cache. The GUI screen is a content selection screen (recording list or the like) configured over a plurality of pages, and icon images B1 and B2 and the like of the next page (second page) are similarly held as a cache. And the priority order of each cache data at the time of this full screen display is determined as B1, B2, A1, A2,... According to the rule α.

  Here, as shown in FIG. 1B, the display mode of the screen is switched to “two-screen display”, a photographic image by the image viewer is displayed on the left side of the screen, and a GUI screen (recording list) is displayed on the right side. The Then, in the electronic device of this embodiment, the priority order is recalculated based on the rule β different from the previous rule, and the priority order of B1, A1, B2, and A2 is determined. As described above, in the electronic apparatus of this embodiment, the priority order of the cache data can be determined by switching the display mode of the screen.

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the electronic apparatus according to the present embodiment. The electronic device in the present invention refers to an electronic device that can use a plurality of screen layouts. “Screen layout” refers to a display layout within one screen. For example, a display screen layout of processing results of each task in a multitask processing environment (a layout for displaying a full screen, a layout for displaying two screens, a picture-in-picture ( PinP) display layout). The electronic apparatus according to the present embodiment is configured such that one screen layout can be selected from such a plurality of screen layouts. For example, a television receiver, a display device, and other various devices having an information display function are provided. Applicable.

  And the electronic device of a present Example is provided with each component as described below, and they can be implement | achieved as a combination of hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications. Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or hard disk is processed and stored, An instruction for controlling the software is generated. Alternatively, each functional block of the apparatus may be realized by dedicated hardware.

  The present invention can be realized not only as an apparatus but also as a method. A part of the invention can be configured as software. Further, a software product used to cause a computer to execute such software and a recording medium on which the product is fixed are naturally included in the technical scope of the present invention (the same applies throughout the present specification). .

  As shown in FIG. 2, the “electronic device” (0200) of this embodiment includes a “screen layout ID acquisition unit” (0201), a “rule holding unit” (0202), and a “cache unit” ( 0203).

  The “screen layout ID acquisition unit” (0201) has a function of acquiring a screen layout ID currently in use, and can be realized by, for example, a CPU, a main memory, a screen layout ID acquisition program, or the like. Specifically, for example, when the screen layout can be changed by an operation input from the user, there is a configuration in which an ID indicated by the change operation signal is acquired. In addition, when the screen layout is automatically switched, the screen layout ID indicated by the switching instruction may be acquired.

  The “rule holding unit” (0202) has a function of holding a screen layout ID in association with a cache rule that determines a cache priority order of in-screen information that is information displayed on the screen. It can be realized by a storage medium such as a memory. The “in-screen information” refers to information displayed on the screen, and includes text information and image information including icon images.

FIG. 3 is a diagram illustrating an example of the rules held here. As shown in this figure, for example, the rule in screen layout ID: ALL (full screen display) is α = R ₁ (x, y, z,...), And in screen layout ID: PBYP (two screen display). The rule is set such that α = R ₂ (x, y, z,...) (Α: index value indicating priority. X, y, z,...: Download) Each variable, such as time).

  Note that the rules according to the screen layout are not particularly limited as long as the rules are set to have different index values for each layout (or for each layout group). For example, the variables x and y are not limited. , Z..., And so on, a mathematical expression in which the display position of the in-screen information within the current screen, the display size of the in-screen information, the acquisition time of the in-screen information, and the image complexity of the in-screen information . Further, a rule for each screen layout may be set as table data for defining index values using these variables as keys instead of mathematical expressions.

  Further, this rule may be set as a rule in which the priority order of the in-screen information is changed in accordance with the display form of the in-screen information in the changed screen layout. That is, when the screen layout is set to the two-screen display and the recording list over a plurality of pages is displayed on both screens, the in-screen information B1 and B2 of the next page which is hidden in the full-screen display is also displayed. In such a case, a rule is set such that the priority of the in-screen information on the next page having a low priority is increased because it is not displayed during full screen display.

  Alternatively, when the screen layout is changed from full screen display to two-screen display, PinP display, or the like, the resolution of one screen during the latter screen display becomes half or less. Therefore, for example, when there are two types of in-screen information with the same icon image and different resolutions, it is easy to use an icon image with a high resolution during full-screen display, and there is no problem with using a low-resolution image during two-screen display or PinP display. . Therefore, the rule is such that the priority is higher for the information with the same resolution and the higher resolution among the in-screen information with the same resolution when the full screen is displayed, but the priority with the lower resolution is higher when displaying the two screens. An example is a rule.

  Alternatively, as shown in FIG. 4, for example, the display aspect ratio of the GUI screen is 16: 9 during full screen display, and the display aspect ratio of the GUI screen is 8: 9 during two screen display (so-called PbyP display), or A black band or the like may be provided at the top and bottom to display 4: 3. As the display aspect ratio changes in this way, A1 to A4 are displayed as in-screen information during full screen display, whereas a GUI screen composed of a plurality of pages is further displayed during two screen display. The in-screen information B1, B2, C1, etc. from the next page can also be displayed. Therefore, a rule is set so that the priority order of B1, B2, and C1, which are likely to be displayed later due to page transition, is increased during full-screen display, and B1 or B1 already displayed on the first page is displayed during two-screen display. There is an example in which the rules are set such that the priority order of B2 and C1 is lowered.

The “cache unit” (0203) has a function of executing caching of in-screen information using the acquired screen layout ID and a cache rule associated with the acquired screen layout ID. For example, a CPU, a main memory, a cache program, etc. Can be realized. Specifically, as will be described in detail later, for example, if the acquired screen layout ID is ALL (full screen display), an index value α indicating the priority order of information in each screen is calculated using rule R _1. To do. Then, in-screen information managed in association with α is stored in the cache memory. On the other hand, when the screen layout is changed and ID: PBYP (two-screen display) is acquired, the priority index value α of each screen information is recalculated using the rule R ₂ and associated with the screen information. The managed α is updated to a recalculated value.

  In addition, this cache unit may include “cache priority order acquisition means” and “discard means” (not shown). The “cache priority acquisition unit” has a function of acquiring the cache priority of the in-screen information based on the cache rule. The “discard means” has a function of discarding the in-screen information cached in ascending order of the acquired cache priority. Therefore, when the cache memory cannot hold all the in-screen information, the index value α indicating the priority managed in association with the in-screen information is referred to, and the in-screen information is discarded in descending order of α. It is a condition of going.

  In addition, the cache discarding process may further include the following configuration. As shown in FIG. 5, the cache memory is a shared memory, and stores content display data for displaying content in the currently used screen layout and the cache data at the same time. Therefore, as described above, for example, when the screen layout is changed from full screen display to two screen display and the occupied storage capacity of the content display data in the memory increases, the cache memory capacity decreases as a result. Therefore, the cache unit calculates the memory size that can be used for storing cache data in the memory in the currently used screen layout, and discards the information in the screen according to the calculated memory size and the acquired priority order. Condition.

  Hereinafter, the cache processing including discarding of in-screen information during full screen display of the GUI screen and two screen display including the same GUI screen will be described with reference to FIGS. 6 and 7. In this example, the GUI screen is composed of a plurality of pages. However, at the time of full screen display, such a plurality of pages is not taken into consideration, and basically the information in each screen (icon image, etc.) A rule that preferentially caches a long download time or display processing time is used. On the other hand, at the time of two-screen display, as described above, the capacity of the cache memory is reduced by the amount of another screen display as compared with the case of full-screen display, so that much in-screen information cannot be cached. Therefore, in order to prevent an image icon or the like from being displayed at all immediately after the GUI screen display is switched due to the page transition, information on each screen arranged on the left side of each page which is likely to be noticed first ( An example will be described in which a rule in which the priority order of the first page A1, the second page B1, the third page C1) in FIG. Of course, this is only an example, and if the rules used to acquire the cache priority order are different depending on the display form of the GUI screen, for example, when the entire screen is displayed, the arrangement position of the information in the screen is given priority. Any rule may be used, such as a rule that considers the download time or the like when the two screens are displayed.

FIG. 6 is a conceptual diagram for explaining an example of cache processing in the cache unit when the GUI screen is displayed on the full screen. As shown in this figure, for example, the data (A1 to C2) that is the in-screen information of the GUI screen consisting of a plurality of pages is given a score (number of milliseconds) according to the download (DL) time and display processing (development) time Has been. And are coefficients determined such each such screen arrangement position screen priority or next screen priority of each data by the rules R ₁ at full screen. And calculated by equation shown the scores and factor in the rule R _1, the priority index value α of each screen in the information A1~C2 is calculated.

  The calculation formula is not particularly limited, but examples include “α = (DL time + display processing time) * in-screen priority * next screen priority * other coefficient”.

  In-screen priority indicates the priority of information in each screen within the same screen, and the next screen priority is likely to be required when switching to the next screen in view of the current screen layout. It may be set as indicating the degree of necessity of in-screen information. Specifically, for example, as a concept of in-screen priority, when a new GUI screen is displayed, the user's line of sight is first sent to the upper left rather than the lower right. There is an example in which the in-screen priority of the in-screen information arranged on the left side and in the vertical direction is set higher). Or, the information in the screen once selected with the cursor is highly likely to be selected again, or conversely, if it is a recording list, etc., a screen showing a recorded program (not selected with the cursor) It is also possible to set the priority of the in-screen information that has been selected many times to be higher or lower in consideration of the past operation selection history and the like. .

  As the next screen priority, for example, the next screen switching is a loop type, that is, the last screen information is displayed, and when the next screen display switching is performed, the first screen information is displayed. In this case, if the current screen layout is the display of the last in-screen information, an example is given in which the priority order of the first in-screen information is set higher. Also, when the next screen is switched in page units, when page switching is considered to occur continuously (such assumption may be made in advance, or when the input interval of the immediately previous page switching operation is continuously shortened) It may be determined that the screen can be switched continuously in the future), and if the information on the screen is not displayed by switching the page, it will not lead to a suitable operation feeling of the user. A higher next screen priority may be used.

  As another coefficient, for example, “resolution priority” can be cited. This is because the in-screen information such as multiple images with the same content and different resolutions can be easily acquired by resizing the in-screen information with a large resolution without caching the in-screen information with a small resolution. This is a parameter for setting the latter priority higher. Further, as in the prior art, the order of last access may be used as other coefficients.

  And, for example, adding the in-screen priority and next-screen priority of each in-screen information set as in the above example to the above formula, DL time, display processing time, and other factors, and currently displaying The priority index value (α) of the in-screen information A1 is 720, A2 is 600, A3 is 500, A4 is 300, B1 of the next page is 1040, B2 is 220, and C1 of the third page is 1800, C2 is calculated to be 900.

  Therefore, when the capacity of the cache memory is tight and it becomes necessary to delete the cache data, the priority of each data indicated by the priority index value, the remaining capacity of the cache memory, and the capacity of each cache data, For example, cache data C1, B1, and C2 whose remaining capacity is within the remaining capacity in descending order of priority are left, and the remaining data are discarded.

FIG. 7 is a diagram for explaining an example of cache processing in the cache unit when displaying two screens including the same GUI screen as described above. As shown in this figure, for example, for data A1 to C2 which are in-screen information, scores according to the download (DL) time and display processing (development) time, and coefficients such as in-screen priority and next screen priority Is given in the same manner as above. This time, according to the rule R _{2 for} displaying two screens instead of the rule R _{1 for} displaying full screen, the priority index value of the currently displayed in-screen information A1 is 1200, A2 is 600, A3 is 500, and A4 is 300, B1 of the next page is 2000, B2 is 220, C1 of the third page is 3400, C2 is 900, and so on.

  Therefore, when the cache data needs to be discarded as described above, the total capacity is within the remaining capacity in the descending order of priority. For example, in addition to the cache data C1 and B1, the full screen display characters are discarded. A1 is left, and the remaining data including C2 left at the time of full screen display is discarded.

  As described above, in the electronic device of this embodiment, when a plurality of screen layouts such as full screen display and two screen display are selected and used, the priority order of the cache data is appropriately determined according to the selected screen layout. The cache can be discarded according to the priority.

<Hardware configuration>
FIG. 8 is a schematic diagram illustrating an example of the configuration of the electronic device when the functional components are realized as hardware. The operation of each hardware component in the in-screen information cache process will be described with reference to FIG.

  As shown in this figure, the “CPU (central processing unit)” (0801) and “main memory” (0802), which are the screen layout ID acquisition unit and the cache unit and execute other arithmetic processing, Electronic equipment is provided. Also, a “flash memory” (0803) that is a rule holding unit, a “display” (0804) that displays various screens identified by the screen layout ID, an “input device” (0805) that receives an operation input from the user, an external It is also preferable to provide a “broadcast reception tuner” (0806), an “Internet connection circuit” (0807), etc. for acquiring in-screen information from the network. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, via the “input device”, for example, an operation for displaying a thumbnail list for selecting moving image distribution contents on the Internet in full screen display is input by the user. Then, the “CPU” interprets the screen layout ID acquisition program, acquires the screen layout ID “ALL” (full screen display) indicated by the input operation according to the interpretation result, and stores it in the address 1 of the “main memory”. To do.

  The “CPU” interprets a screen display program (not shown), etc., accesses the video distribution server from the “Internet connection circuit” according to the interpretation result, and displays the thumbnail image (screen of the distribution video as display thumbnail list information). Internal information) and the like are acquired and stored in address 2 of the “main memory”. The selection thumbnail list is displayed on the “display” using the display information of the acquired thumbnail image and other selection thumbnail lists. At that time, the “CPU” counts the download time and display processing time for each thumbnail image, and stores and manages the count information in the address 3 of the “main memory” in association with the ID of the thumbnail image.

  Subsequently, the “CPU” interprets the cache program, and in accordance with the interpretation result, first, using the acquired screen layout ID: ALL as a key, associate it with ALL from among a plurality of cache rules held in the “flash memory”. The cache rule A that is managed and held is specified. Then, according to the specified cache rule A, the download time and display processing time for each thumbnail image, the display position of the thumbnail image indicated by the thumbnail display information, and the display page when the selection thumbnail list covers a plurality of pages, etc. Based on the numerical value, an index value indicating a cache priority order for each thumbnail image is calculated by a calculation process of “CPU”. The calculated index value is managed in association with the thumbnail image ID, and the cache data of the thumbnail image is stored in the address 4 of the “main memory”. At that time, if the data capacity of the thumbnail image exceeds the capacity limited for cache data, the “CPU” determines the thumbnail image in descending order of the priority index value of the thumbnail image according to the interpretation result of the cache program. To the limit capacity.

  Thereafter, when an operation input for switching the screen layout to “two-screen display” for displaying a television image received by the “thumbnail list for selection” and the other “broadcast reception tuner” via the “input device” is received, “CPU” Acquires the screen layout ID “PBYP” (two-screen display) indicated by the input operation according to the interpretation result of the screen layout ID acquisition program, and stores it in the address 1 of “main memory”.

  Subsequently, according to the interpretation result of the cache program, the “CPU” executes a plurality of cache rule search processes using the PBYP as a key, and specifies a cache rule B different from the cache rule A. Similarly, in accordance with the cache rule B specified in the same manner, the index value for each thumbnail image is determined based on the numerical values such as the download time, display processing time, thumbnail image display position, and display page for each thumbnail image. Calculates an index value indicating a different cache priority by an arithmetic process of “CPU”. The calculated index value is managed in association with the thumbnail image ID, and the cache data of the thumbnail image is stored in the address 4 of the “main memory”.

  At this time, since it is a two-screen display, a partial capacity of the “main memory” is used for broadcast program display. Therefore, the capacity for cache data is lower than the previous capacity. Therefore, the “CPU” caches the thumbnail images up to the limit capacity in descending order of the priority index values of the thumbnail images different from the previous one according to the interpretation result of the cache program. Alternatively, the cache data of the thumbnail image that was previously discarded is cached.

<Process flow>
FIG. 9 is a flowchart illustrating an example of a process flow in the electronic apparatus of the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care.

  As shown in this figure, first, in an electronic device that can use a plurality of screen layouts, the screen layout ID currently being used is acquired (step S0901). Then, using the acquired screen layout ID and the cache rule previously stored in association with the screen layout ID in the rule holding unit configured with a storage medium, the in-screen information is cached (step S0902). . Thereafter, the screen layout is changed in accordance with the user operation or the like (step S0903), and when another screen layout ID is acquired, the above process is repeated, and this time, this is associated with another screen layout ID and stored in advance in the rule storage unit. The in-screen information is cached using a cache rule different from the previous cache rule.
