Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to clarify the technical idea of the present invention. When describing the present invention, detailed descriptions of known related functions or constituent elements that are judged to be unnecessary and confuse the gist of the present invention will be omitted. For the components having the same functional structure in the drawings, even if they are shown on different drawings, the same reference symbols and reference symbols are given as much as possible. For the convenience of explanation, the equipment and method are explained together when necessary.

FIG. 1 is a diagram showing a schematic configuration of a switching advertisement providing system that executes a method for providing switching advertisements according to an embodiment of the present invention.

Referring to FIG. 1, an embodiment of the present invention The report providing system 10 includes: a broadcast content providing server 100, a central server 200, a broadcast receiving device 300, an intermediate management server 400, and a plurality of distributed servers 411, 413, ..., 415; 410. According to an embodiment, the switching advertisement providing system (10) further includes an advertiser terminal device (not shown) applying for switching advertisements. A network 500 is formed between each constituent element constituting the switching advertisement system (10) to transmit and receive signals with each other.

The broadcast content providing server 100 provides various forms of digital broadcast content to the broadcast receiving device 300. The broadcast content providing server 100 includes: a terrestrial station, a local cable station, an interactive network (IPTV: Internet Protocol Television) station, a satellite station, a video on demand (VOD: Video On Demand) server, an application server, and the like. According to an embodiment, the broadcast content providing server 100 receives a signal requesting specific broadcast content from the broadcast receiving device 300 together with the channel switching signal, and transmits broadcast content information corresponding to the request to the broadcast receiving device 300 through the network 500.

In the process of providing digital broadcasting, the broadcast receiving device 300 receives the compressed data from the broadcast content providing server 100 and is necessarily displayed on the screen along with the decompression, and therefore, the time generated by the signal processing will inevitably occur delay. In this specification, the time difference that occurs during the broadcast receiving process is referred to as the switching time, and eventually the switching time will appear during the process of changing the broadcast content. For example, during continuous listening to the corresponding broadcast content in one broadcast channel, the switching time delayed by the process of receiving, releasing, and processing the broadcast content is continuous, thereby reducing the inconvenience caused by the switching time. But listen to one radio content, then listen to the other When broadcasting content, for example, when changing channels, no broadcast content can be displayed during the switching time due to the processing of the corresponding broadcast content. In the present invention, during the switching time, the switching advertisement is displayed on the user's screen using the point where the broadcast content is not displayed.

The central server 200 stores the switching advertisement editing data and the switching advertisement data necessary for switching the advertisement editing, and periodically provides the switching advertisement data or the switching advertisement editing data to the broadcast receiving device 300 according to the embodiment. Switching advertisement data includes advertisements such as content, enterprises, products, and services. However, according to an embodiment, switching advertisement editing data includes: switching creative material information, switching advertisement display information, and switching advertisement additional information. The central server 200 stores all edited switching advertisement data.

Specifically, the switching advertisement data transmitted to the user's broadcast receiving device 300 is provided to the user, that is, the user, in the form of keywords, graphic images, dynamic images, and sounds. For switching advertisement data, the identification and other information used to identify the switching advertisement is the switching creative information, and the graphic image, dynamic image, sound and other information provided directly to the user are the display information of the switching advertisement. In the case of switching ads, more specific information provided separately corresponds to the additional information for switching ads.

According to an embodiment, the central server 200 performs functions such as receiving an application for switching advertisements from an advertiser, calculating a fee corresponding to the switching advertisement, and requesting an advertisement fee from the advertiser.

The broadcast receiving device 300 receives various forms of digital content from the broadcast content providing server 100 and displays it on the screen. The server 200 receives switching advertisement data and stores and displays it.

The broadcast receiving apparatus 300 includes a digital multimedia broadcast (DMB: Digital) including a built-in digital video conversion box for receiving ground wave, satellite or cable broadcasting, a TV with a built-in digital video conversion box function, and a network-based IPTV Multimedia Broadcasting) or handheld digital TV (DVB-H: Digital Video Broadcasting-Handheld) receiving module for mobile phones, smartphones, laptops, tablets, personal multimedia players (PMP: Personal Multimedia Player), navigators and other digital equipment.

It will be described later, but in the broadcast receiving device 300, during the time when the broadcast content is not displayed, since the switching advertisement material displayed in the lower part of it naturally appears, the broadcast receiving device 300 should store a part of the switching advertisement data. However, the broadcast receiving device 300 stores and executes various application programs for providing broadcast content, and thus, there is a limitation in storing switching advertisement data. Therefore, it is necessary to use the small storage space of the broadcast receiving device 300 and to effectively provide a method for switching advertisement materials.

The advertiser terminal device is a terminal device that can be accessed by an advertiser who needs to switch advertisements, and the advertiser accesses the central server 200 through the advertiser terminal device to apply for switching advertisements. The advertiser terminal device determines the channel for providing the switching advertisement, the time period for providing the switching advertisement, the exchange period for switching the advertisement, etc. on the switching advertisement application screen provided by the central server 200, and applies for switching the advertisement. According to the embodiment, the advertiser terminal device includes a network-connected power supply including a personal computer Child device.

The central server 200 maps specific advertisements and channels, advertisement provision time periods, etc. based on the application for switching advertisements of the advertiser's terminal device, thereby generating switching advertisement editing materials. According to the embodiment, the switching advertisement editing data is stored in the central server 200 or transmitted to the broadcast receiving device 300 at a set cycle.

The network 500 serves as a wired/wireless communication network such as a terrestrial wave, satellite, cable, or network, and serves as a broadcast content providing server 100 and broadcast receiving device 300, central server 200 and broadcast receiving device 300, central server 200, and intermediate management The communication medium between the servers 400. The broadcast content providing server 100 transmits the broadcast content to the broadcast receiving device 300 through the network 500, and the central server 200 transmits the address of the switching creative information and/or the switching advertising data and the intermediate management server to the network 500 Broadcast receiving device 300. The intermediate management server 400 receives the request to switch the advertisement data or is connected to the central server 200 via the network 500 from the broadcast receiving device 300. In FIG. 1, it is shown that a plurality of distributed servers 410 are connected to the network 500 through the intermediate management server 400, but the plurality of distributed servers 410 can be connected to other constituent elements through the network 500, respectively.

FIG. 2 is a conceptual diagram for explaining a layered structure suitable for a digital display screen.

Referring to FIG. 2, the digital display screen is composed of multiple planes (BP, VP, GP, CP). Each plane has a specific function in theory, and each plane has a vertical hierarchy. That each plane is in theory There is a hierarchy of priority listening, and the user views the screen that vertically overlays and displays the entire plane.

The background plane (BP) is the plane that is theoretically at the bottom, and displays the decoded video or image statically. Generally speaking, the background plane (BP) only supports MPEG-2i-frame (defined in ISO/IEC13818-2), JPEG (Joint Photographic Experts Group, defined in ISO/IEC10918-1) and other formats.

The video plane (VP) is a plane that outputs decoded video, and is a plane that outputs broadcast content. According to an embodiment, a digital display screen includes a plurality of video planes (VP), and a plurality of videos are decoded and displayed on each plane. According to an embodiment, a chip that supports the Picture-In-Picture (PIP: Picture-In-Picture) function simultaneously displays this screen and another small screen on the display screen. In this case, multiple videos are decoded and displayed to the user at the same time.

A graphics plane (GP), as a plane for displaying information based on images or text, includes at least one graphics plane. Moreover, the graphics plane supports various colors and resolutions. For example, the graphics plane is used to display various applications (VOD, etc.) provided by the broadcast receiving device 300, channel numbers, program information, broadcast edit tables (EPG, Electronic Program Guide), etc. The graphics plane is displayed preferentially with the video plane and the background plane. The information displayed in the graphics plane covers the screen of the video plane and is displayed according to the area where the corresponding information is displayed.

According to an embodiment, the digital display screen further includes a cursor plane (CP). Cursor plane (CP) refers to the plane used to display the cursor input through the hardware on the screen, and is used in the system chip (SoC: System On Chip) may not be provided.

In this specification, the relationship between multiple planes is theoretically placed in the lower part and displayed. However, when visual observation is performed, the plane in the upper part theoretically covers the plane in the lower part. Therefore, the background plane ( BP) is shown behind the video plane (VP), graphics plane (GP), and cursor plane (CP). Also, in this case, the cursor plane (CP) is displayed on top of other planes (BP, VP, GP).

In the present invention, the broadcast receiving apparatus 300 is explained based on providing a display screen including a video plane (VP) displaying broadcast content and a background plane (BP) displaying switching advertisement materials in a plurality of planes. However, the present invention is not limited to these two planes. When the broadcast content and the switching advertisement material are theoretically displayed on the upper and lower sides, and when the broadcast content is displayed, the switching advertisement material is distinguished, and the switching advertisement material is only displayed when the broadcast content is not displayed. Full display.

Therefore, while the broadcast content is displayed on the video plane (VP), only the broadcast content is displayed regardless of whether the advertisement material is switched to be displayed on the background plane (BP) or not displayed on the background plane (BP). However, when the user changes from the currently viewed broadcast content to another broadcast content by changing the channel or the like, the broadcast receiving device 300 receives the new broadcast content from the broadcast content transmission device 100 and displays it on the video plane (VP) , To generate the time when no information is displayed on the video plane (VP), that is, the switching time. In this case, the switching advertisement material is displayed on the background plane (BP), and when there is no display on the video plane (VP), the switching advertisement material is naturally displayed.

With the broadcast content displayed on the video plane (VP), It is necessary to display the switching advertisement material on the background plane (BP) in advance. In particular, when there is a change in the switching advertisement material, it is preferable to confirm the switching advertisement material and display it while the broadcast content is displayed on the video plane (VP).

According to the embodiment, the information displayed on multiple planes is mixed in the broadcast receiving device 300 and transmitted and received as a signal.

FIG. 3 is a sequence diagram for explaining a method for providing switching advertisements according to an embodiment of the present invention.

Referring to FIG. 3, the broadcast receiving apparatus 300 detects a state change condition (step S311). The state change condition is a specific condition on the broadcast receiving device 300, and corresponds to a condition in which a new switching advertisement material is displayed or updated in a specific layer constituting the display screen.

According to an embodiment, the status change conditions include: power on/off of the broadcast receiving device 300, power on/off of the display device (eg, TV, etc.), channel switching, execution and end of the application, and information sent and received by the application , Switch advertisement information changes (for example: switch advertisement edit information update, etc.), etc.

More specifically, when the power of the broadcast receiving device 300 or the display device is changed from the on state to the off state or from the off state to the on state, the broadcast receiving device 300 detects the state change of the broadcast receiving device 300 or the display device and Judgment according to the condition of condition change. In particular, when the display device is switched from the off state to the on state, the display device needs to display all the switching advertisement material and the broadcast content. Therefore, there is a switching device material that needs to be identified to be displayed on the display device. 300 If the condition is met, the condition is changed according to the status To be tested.

In addition, when a user listens to a channel currently broadcasting content, if the channel is changed to a channel that provides other broadcasting content or requests to change the broadcasting content, the broadcast receiving device 300 judges according to the state change condition by the channel switching signal. For example, the channel change signal includes an infrared signal for remote control provided to the broadcast receiving device 300.

In addition, the switching advertisement material is edited in association with the broadcast content watched by the user through the broadcast receiving device 300. Even if the broadcast receiving device 300 receives the channel change signal, in the case where the user continuously changes channels, the user can simply move the channel according to the user The situation is judged, and a switching advertisement material edited by the previously watched channel is continuously displayed. That is, the condition detection unit 310 determines that the channel is continuously changed as a state change condition. The continuous channel change according to the embodiment is determined based on receiving the channel change signal within the set time.

After the channel switching signal is input, when the channel switching signal is not input during the set time, the broadcast receiving device 300 judges according to the converted channel watched by the user, and judges that the edited switching advertisement data needs to be displayed again for the corresponding channel. Therefore, after receiving the channel switching signal, the broadcast receiving device 300 considers that the channel switching signal has not been input within the set time as the channel viewing condition, and judges it according to the state change condition.

According to an embodiment, a user who views channels providing various broadcast contents by switching advertisement materials may edit a program at a specific time period. Therefore, even if the broadcast receiving device 300 says that the channel has not been changed, And according to the situation that the advertisement editor should change the displayed switching advertisement data, it is also detected according to the state change condition. For example, the broadcast receiving device 300 detects the state change condition at the set time interval. According to the embodiment, the advertisement editing material for switching broadcast programs is provided by the central server 200.

In other embodiments, in the case where the user reserves a broadcast program through the broadcast reservation application, the broadcast reservation application of the broadcast receiving device 300 generates various command signals for processing the scheduled broadcast and will execute the broadcast reservation application according to The command signal generated by the program is judged according to the state change condition. That is, a specific broadcast program is displayed as broadcast content according to the execution of the broadcast reservation application program, and the switched advertisement data edited in the corresponding broadcast content should be displayed on the background plane.

According to the embodiment, in the case where the state change condition is the user's operation behavior, the broadcast receiving apparatus 300 receives the operation signal from the remote controller or the display device to detect the state change condition. In addition, the broadcast receiving device 300 receives various signals from the broadcast content providing server 100 or the central server 200, and detects a state change condition, for example, when a change occurs to information on broadcast content or information about switching advertisements, and receives the change signal And it is detected according to the status change condition.

The broadcast receiving device 300 that detects the condition change condition in this way transmits the channel information as the basis for displaying the switching advertisement data to the central server 200 (step S312). As described above, the switch advertisement data is edited for a specific channel, and along with the transmission of channel information that provides the broadcast content that the current user listens to, the central server 200 determines whether a certain switch advertisement data is displayed on the broadcast receiving device 300.

The central server 200 exports the advertisement material information based on receiving the channel information provided by the broadcast receiving device 300 (step S321). Creative information refers to information that forms part of the switching advertisement data or information that identifies the switching advertisement data. That is, the central server 200 does not transmit all the switching advertisement data to be displayed to the broadcast receiving device 300 based on the channel information, and only exports switching advertisement material information that can identify the corresponding switching advertisement data.

For example, based on the channel information for viewing the broadcast content provided by the broadcast receiving device 300, the central server 200 exports switching advertisement data edited for the corresponding broadcast content or the corresponding channel. It can store the edited data for switching advertisements in the central server 200.

The central server 200 transmits the exported switching creative information together with the address of the intermediate management server to the broadcast receiving device 300 (step S322). The central server 200 manages all information including the switching of advertisement data information. Assuming that all central servers 200 connected to the broadcast receiving device 300 transmit all information to the broadcast receiving device 300, the network load of the central server 200 is quite large. Therefore, failed to provide switching ads properly. As shown above, the switching of advertising data needs to be displayed in advance in a faster time than the broadcast content. Therefore, it is required to reduce network load and network connection time.

Therefore, the central server 200 provides the minimum information identifying the switching advertisement data, that is, the switching material information, together with the address of the intermediate management server to the broadcast receiving device 300. According to the embodiment, the central server 200 additionally displays the switching creative information and the address of the intermediate management server. In the case where the address of the intermediate management server is fixed, the broadcast server is initially connected. When the receiving device 300 transmits the address of the intermediate management server once, it is also possible to transmit only the creative material information after detecting the new state change condition.

The broadcast receiving apparatus 300 detects whether or not to store the switching advertisement data corresponding to the switching advertisement material information in the broadcast receiving apparatus 300 based on the switching advertisement material information received by the central server 200 (step S313).

The broadcast receiving device 300 is provided with a space capable of storing the switching advertisement material. Since the broadcast receiving device 300 requires various functions, it is very difficult to secure a space for storing the switching advertisement material. According to the embodiment, in the broadcast receiving device 300, only a few switching advertisement materials are stored in the volatile memory. The volatile memory (volatile memory) included in the broadcast receiving device 300, such as dynamic random access memory (DRAM: Dynamic Random Access Memory) or static random access memory (SRAM: Static RAM), etc., when power is lost, The data disappears, but it is a storage area with fast access speed.

In the case where the switching advertisement data is stored in the volatile memory (step S313, YES), the broadcast receiving device 300 directly displays the corresponding switching advertisement data on the background plane (step S315).

According to the embodiment, the switching advertisement data stored in the broadcast receiving device 300 is managed according to storage rules. According to the embodiment, the storage rule is determined according to the storage capacity of the broadcast receiving device 300, the size of the switching advertisement material, the editing frequency, the creation date, the storage date, the end date, the switching display frequency of the advertisement material, and the like.

For example, in a case where only three switching advertisement data or only 1 Mbyte of switching advertisement data is stored in the storage space of the broadcast receiving device 300, the broadcast receiving device 300 retains only the three recently displayed switching advertisement data or 1 Mbyte, and Delete other switching advertising materials. The storing and deleting actions of the switching advertisement data are executed according to the set time period for receiving new switching advertisement data or receiving commands from outside. Alternatively, in an embodiment, when the switching advertisement data is received by another server, the switching advertisement data also includes information as to whether it is stored in the storage space of the broadcast receiving device 300.

When the broadcast receiving device 300 does not store the switching advertisement data (step S313, No), the broadcast receiving device 300 requests the intermediate management server 400 to switch the advertising data according to the address of the intermediate management server transmitted by the central server 200. (Step S316).

The intermediate management server 400 is physically the same as or separated from the central server 200, and a load balancing server (Load Balancing server) that distributes requests for switching advertisement data received from multiple broadcast receiving devices 300 to multiple distributed servers 410 Server) corresponding.

According to the embodiment, the intermediate management server 400 is connected to a plurality of distributed servers 410 to control the state of the distributed servers 410 in real time. Thus, the intermediate management server 400 selects to handle the switching transmitted from the broadcast receiving apparatus 300 based on the respective load status and network status of the distributed server 410 and the switching advertisement data stored in the distributed server 410 according to the embodiment The distributed server of the request for the advertising material transmits the request to the corresponding distributed server.

According to the embodiment, the intermediate management server 400 receives the identification information of the broadcast receiving device 300 from the broadcast receiving device 300. The identification information on the broadcast receiving device includes regional information such as the location information of the broadcast receiving device or the information of the joined broadcast business. The intermediate management server 400 selects the cloth server closest to the geographical position of the broadcast receiving device 300 based on the identification information of the broadcast receiving device, transmits the request of the broadcast receiving device 300, and provides the switching advertisement data corresponding to the request.

However, according to the embodiment, the intermediate management server 400 determines the decentralized server that most effectively transmits and receives data with the broadcast receiving device 300, and the connection with the broadcast receiving device 300 is not the geographic location of the broadcast receiving device 300. In addition, the intermediate management server 400 specifies an appropriate distributed server in consideration of the geographical position of the broadcast receiving device 300 and the load of each distributed server.

The intermediate management server 400 requests switching of advertisement data to the designated distributed server (step S332). The intermediate management server 400 transmits the identification information of the broadcast receiving device 300 to the designated distributed server 410, whereby the distributed server 410 can also be controlled to directly communicate with the broadcast receiving device 300. In other embodiments, the distributed server 410 can communicate with the broadcast receiving apparatus 300 through the intermediate management server 400.

The distributed server 410 requesting to receive switching advertisement data judges whether the requested switching advertisement data is stored internally (step S341). The distributed server 410 has a smaller data capacity than the central server 200, and therefore, like the central server 200, not all switching advertisement data is stored in the distributed server 410.

It is determined that the requested switching advertisement data is not stored in the distributed server 410 (step S341, No), and the central server 200 is requested to switch the advertisement data accordingly. The distributed server 410 communicates directly with the central server 200 or through the intermediate management server 400.

The distributed server 410 requests the central server 200 receiving the switching advertisement data to transmit the corresponding switching advertisement data to the distributed server 410 (step S323).
