Description

Display device and control method thereof

[0001] The present invention relates to display devices (e.g., TVs, mobile devices, PCs, etc.). In particular, it is applicable to TVs and other devices that store and use various applications in memory. However, the present invention is not necessarily limited to TVs.

[0002] Not only mobile phones, but also TVs have become smart devices. This means that various applications can be accessed through TV.

[0003] However, since the unused applications are always in a preloading state, the screen transition speed when changing channels is slow, and the communication traffic cost for maintaining the preloading state for numerous applications increases exponentially.

[0004] Figure 1 shows the expected costs for server management by year according to the prior art.

[0005] As mentioned above, according to conventional technology, when a TV, an example of a display device, is turned on, the Channel Home application is preloaded and runs in the background. This process generates traffic with the server.

[0006] As shown in Figure 1, each OS or platform incurs approximately 140 million in server-related costs.

[0007] Therefore, based on a given TV product, server costs are expected to reach approximately KRW 280 million by the end of 2024, and considering the five-year TV replacement cycle, they are expected to surge to approximately KRW 700 million per year starting in 2027.

[0008] Therefore, there is a need for systems and protocols that can solve such problems.

[0009] One embodiment of the present invention seeks to reduce data traffic costs with a server by not performing preloading for any application.

[0010] One embodiment of the present invention seeks to improve the channel switching speed, for example, on TV, by not performing preloading for any application.

[0011] A method for controlling a display device according to any one of the embodiments of the present invention comprises the steps of storing at least one application in a memory of the display device, starting booting of the display device, determining whether to preload before selecting a specific application among the at least one application stored in the memory, and triggering preloading when a specific condition is satisfied based on history information stored in the memory.

[0012] The above specific condition means, for example, that the specific application has been used for a preset period of time or more within 7 days prior to the start of the boot. Here, the preset period corresponds to, for example, 10 seconds.

[0013] The above triggering step is characterized in that it uses specific data stored in the memory without requesting specific data for the specific application to a server for preloading.

[0014] The specific data includes, for example, at least one of a thumbnail image or a font file related to the specific application.

[0015] A display device according to one embodiment of the present invention includes a memory storing at least one application, and a controller.

[0016] In particular, the controller is designed to initiate booting of the display device, determine whether to preload before selecting a specific application from among at least one application stored in the memory, and trigger preloading if a specific condition is satisfied based on history information stored in the memory.

[0017] It is also within the scope of the present invention for a third party to implement a computer-readable medium (e.g., an application, memory, software, etc.) recording a program for performing any of the above-described methods and various embodiments described in the specification.

[0018] According to one embodiment of the present invention, data traffic costs with a server can be reduced by not performing preloading for any application.

[0019] According to one embodiment of the present invention, there is a technical effect of improving the channel switching speed, for example, for TV, by not performing preloading for any application.

[0020] In addition to the technical effects described above, it is self-evident that effects that can be inferred by a person skilled in the art from the entire specification should also be taken into consideration.

[0033] FIG. 2 is a block diagram illustrating components of a display device according to one embodiment of the present invention.

[0034] As illustrated in FIG. 2, a display device (100) according to one embodiment of the present invention includes a memory (110), a display (120), a controller (130), etc. If the display device (100) is a TV, it may be controlled wirelessly via a remote control (140).

[0035] The memory (110) stores at least one application.

[0036] The controller (130) initiates booting of the display device (100) and determines whether to preload before selecting a specific application among at least one application stored in the memory (110).

[0037] And, the controller (130) triggers preloading only for a specific application when a specific condition is satisfied, based on the history information stored in the memory (110).

[0038] The above specific condition means, for example, that the specific application has been used for a predetermined period (e.g., 10 seconds) or more within the seven days prior to the booting start. More specific examples related to this will be described in more detail below with reference to FIGS. 4 and 5.

[0039] Furthermore, the controller (130) is characterized in that it uses specific data stored in the memory (110) without requesting specific data for the specific application from the server for preloading.

[0040] And, the specific data includes, for example, at least one of a thumbnail image or a font file related to a specific application.

[0041] Meanwhile, according to one embodiment of the present invention, an application in which preloading is triggered only under certain conditions will be described in more detail below with reference to FIG. 3.

[0042] Figure 3 is a diagram illustrating various applications that can be preloaded.

[0043] FIG. 3 illustrates a list of applications that can be preloaded according to one embodiment of the present invention.

[0044] The preload types illustrated in Figure 3 are divided into one-shot and periodic. For applications corresponding to the one-shot type, preloading occurs once after the A / C boots. On the other hand, for applications corresponding to the periodic type, if the application terminates after preloading, re-preloading can be designed to occur periodically if there is free memory.

[0045] Meanwhile, the priority for preloading can be established based on two criteria.

[0046] When using dynamic priority, preloading is designed to occur only for applications that have been used for a certain period of time (e.g., more than 10 seconds). For example, this means the case where the priority shown in Figure 3 is “10.”

[0047] On the other hand, when using a static priority, since it is a critical application, it is designed to be preloaded unconditionally unless it has been inactive for more than 7 days, regardless of the usage period. For example, this refers to the case where the priority shown in Figure 3 is "1."

[0048] However, a channel-related application (310) is added to FIG. 3, which requires a large amount of memory. If a user always preloads the channel-related application (310) regardless of whether the application is used or not, there is a problem that the annual server cost increases exponentially (especially if the OS is updated annually).

[0049] Figure 4 is a flow chart illustrating a control method of a display device according to one embodiment of the present invention.

[0050] For example, by designing the application (310) related to the channel illustrated in FIG. 3 so that preloading is performed only for TVs used 7 days ago, for example, server traffic can be minimized.

[0051] Therefore, the server management cost per OS / platform, which was approximately $112,260 (KRW 140 million) per year according to the prior art, can be reduced by 86% to approximately $15,816 (KRW 200 million).

[0052] To explain the experimental data more specifically, the cumulative number of TVs (A) using the application (310) related to the channel was 1,909,085, the ratio of the number of TVs turned on among the TVs connected to the Internet (B) was 0.9, and the average number of AC boots per TV per month (C) was 5.5. The average number of AC boots per TV per month (C) is calculated as the average monthly TV usage time (131.14 hours) / 24 hours. Here, the reason for dividing by 24 hours is that it is assumed that the TV AC boots every 24 hours, but the present invention can also be applied to a TV that AC boots every 12 hours.

[0053] Server traffic (D) generated 0.011 GB. More specifically, 3 MB of data was required for application code and 8 MB for application data. The cost per GB (E) was $0.09.

[0054] Therefore, if we multiply all of the aforementioned A factor, B factor, C factor, D factor, and E factor, the monthly server cost according to the prior art was $9,355.

[0055] In order to solve the above-mentioned conventional technology problem, as shown in FIG. 4, a display device according to an embodiment of the present invention stores at least one application in memory (S410).

[0056] When booting the above display device starts (S420), before selecting a specific application among at least one application stored in memory, it is determined whether preloading is performed (S430).

[0057] In particular, preloading is triggered when certain conditions are met based on the history information stored in memory (S440). For example, preloading is performed only if a specific application has been used within 7 days prior to booting.

[0058] Therefore, the aforementioned A factor can be reduced (from 1,909,085 to 328,729 (users within 7 days)).

[0059] Furthermore, according to another embodiment of the present invention, the D factor can be reduced. The application data is reduced from the existing 8M to 6M. To achieve this, the thumbnail image and font files among the application data are not requested from the server, but are instead stored in the TV's memory.

[0060] According to the improved A and D factors as above, if A, B, C, D, and E are multiplied again, only $1,318 is required as monthly server cost (according to the prior art, as mentioned above, $9,355).

[0061] However, if primary filtering is applied only to applications used within 7 days, there is a limitation in performing preloading even on TVs that are only used for a very short time and are unlikely to be reused.

[0062] To solve this problem, the process of applying secondary filtering will be described below with reference to Figure 5.

[0063] FIG. 5 is a drawing for more specifically explaining the specific conditions shown in step S440 of FIG. 4.

[0064] As illustrated in FIG. 5, a display device (e.g., a TV) according to an embodiment of the present invention determines whether a specific application (e.g., a channel-related application (310) illustrated in FIG. 3) used within 7 days prior to booting is present (S441).

[0065] As a result of the above judgment (S441), if there is no specific application used within 7 days, preloading is disabled to minimize server traffic-related costs.

[0066] On the other hand, if there is a specific application that has been used within 7 days as a result of the above judgment (S441), preloading is not performed immediately, but it is designed to additionally determine whether the specific application has been used continuously for more than 10 seconds (S442).

[0067] And, based on the above judgment result (S442), only when a specific application is used continuously for 10 seconds or more, the display device according to one embodiment of the present invention performs preloading for the specific application (S443).

[0068] And, FIG. 6 shows the expected cost reduction for server management by year according to one embodiment of the present invention.

[0069] Compared to Figure 1, the projected server cost decreased from 2.8 billion to 400 million in 2024, from 4.2 billion to 600 million in 2025, and from 5.6 billion to 800 million in 2026. Furthermore, the projected server cost decreased from 700 million to 100 million in 2027.

[0070] As the years go by and the number of operating systems / platforms to manage increases, the technological benefits of the present invention will only grow over time.

[0071] The present invention described above can be implemented as computer-readable code on a medium having a program recorded thereon. Computer-readable media include all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include applications, hard disk drives (HDDs), solid-state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like, and also include media implemented in the form of carrier waves (e.g., transmission via the Internet).

[0072] Although the data processing device and method according to the embodiments of the present invention have been described in specific embodiments, these are merely examples, and the present invention is not limited thereto, and should be construed to have the broadest scope in accordance with the basic idea disclosed in this specification. Those skilled in the art may implement embodiments not specified by combining or replacing the disclosed embodiments, but this also does not exceed the scope of the present invention. In addition, those skilled in the art may easily modify or alter the disclosed embodiments based on this specification, and it is clear that such modifications or alterations also fall within the scope of the present invention.
