2 is a conceptual diagram illustrating a layer structure applied to a digital display screen.

Referring to FIG. 2, a digital display screen may be implemented with a plurality of planes BP, VP, GP, and CP. Each plane logically has a specific function, and each plane has a vertical layer. That is, each plane has a layer that is logically first viewed, and a viewer views a screen in which all planes are vertically overlapped.

The background plane BP is a plane that is logically located at the bottom, and statically displays a decoded video or image. In general, the background plane (BP) supports only specific formats such as MPEG-2 i-frame (defined in ISO/IEC 13818-2) and JPEG (Joint Photographic Experts Group, defined in ISO/IEC 10918-1). .

The video plane (VP) is a plane through which decoded video is output, and is a plane through which broadcast content is output. Depending on the embodiment, the digital display screen may include a plurality of video planes (VPs), and a plurality of videos may be decoded and displayed on each plane. According to an embodiment, a chip supporting a Picture-In-Picture (PIP) function may simultaneously display a small screen separately from a screen viewed on a display screen, and in this case, a plurality of videos may be decoded and displayed to a viewer at the same time.

The graphics plane GP is a plane that displays graphic or text-based information, and may include at least one graphics plane. In addition, the graphics plane can support various colors and resolutions. For example, the graphics plane may be used to display various applications (such as VOD), channel numbers, program information, and broadcast schedules (EPG, Electronic Program Guide) provided by the broadcast receiving device 300. The graphics plane is displayed with priority over the video plane and the background plane, and information displayed on the graphics plane may be displayed while covering the screen of the video plane as much as an area displaying the corresponding information.

According to an embodiment, the digital display screen may further include a cursor plane CP. The cursor plane (CP) is a plane used to display a cursor input through hardware on a screen, and may not be provided in a general TV SoC (System On Chip).

In this specification, the relationship between a plurality of planes is expressed as being logically located at the bottom, but visually, since the plane located at the top logically covers the plane located at the bottom, the background plane (BP) is a video It can be expressed as being located at the rear of the plane (VP), graphics plane (GP), and cursor plane (CP). In addition, in this case, the cursor plane CP may be expressed as being positioned on the upper surface of the other planes BP, VP, and GP.

The present invention describes providing a display screen including a video plane (VP) in which broadcast content is displayed and a background plane (BP) in which zapping advertisement data is displayed among a plurality of planes. However, the present invention is not limited to these two planes, and when broadcast content and zapping advertisement data are logically displayed at the top and bottom of each other and broadcast content is displayed, the zapping advertisement data is hidden, and the zapping advertisement data is not displayed. It is sufficient to be exposed only if not.

According to an embodiment, information displayed on a plurality of planes may be mixed in a broadcast receiving device and transmitted and received as a single signal.

3 is a block diagram showing the configuration of a broadcast receiving device that provides zapping advertisements according to an embodiment of the present invention.

Referring to FIG. 3, the broadcast reception device 300 according to an embodiment of the present invention may include a condition detection unit 310, an information acquisition unit 320, a storage unit 330, and a control unit 340. have.

The condition detection unit 310 may detect a state change condition and generate a command signal according to the sensed state change condition. The condition change condition may correspond to a condition in which new zapping advertisement data should be displayed or updated in a specific layer constituting the display screen by becoming a specific condition in the broadcast reception device 300. Depending on the embodiment, the condition change conditions include power on/off of the broadcast receiving device 300, power on/off of a display device (eg, TV, etc.), channel switching, execution and termination of an application, information transmitted and received by the application, This may include changing zapping advertisement information (eg, updating zapping advertisement scheduling information, etc.).

More specifically, when the power of the broadcast reception device 300 or the display device is changed from an on state to an off state or from an off state to an on state, the condition detection unit 310 is the broadcast reception device 300 or the display device. It can be determined as a condition change condition by detecting that the state of is changed. In particular, when the display device is turned on from the off state, since both the zapping advertisement data and the broadcast data must be displayed on the display device, it is necessary to identify the zapping advertisement data to be displayed on the display device. If this condition is satisfied, it is detected as a condition change condition.

In addition, when a user switches a channel from a current broadcast channel to another broadcast channel, the condition detection unit 310 may detect a channel change signal and determine a condition change condition. However, even if the broadcast receiving device 300 receives the channel switching signal, when the user continuously switches channels, it is determined that the viewer simply moves the channel, and one zapping advertisement arranged on the channel previously viewed. Data can be displayed continuously. That is, the condition detection unit 310 does not determine this state as a state change condition.

However, if the channel switching signal is not input for a preset time after the channel switching signal is input, the condition detection unit 310 determines that the viewer is watching the switched channel and displays the zapping advertisement data arranged for the channel. I judge that it is. Accordingly, the condition detection unit 310 considers a case in which the channel change signal is not input for a preset time after the channel change signal is input as a channel viewing condition and determines this as a state change condition.

According to an embodiment, zapping advertisement data may be organized for each specific time period for viewers who watch a specific channel, respectively. Therefore, even if the channel is not changed, the condition detection unit 310 may also detect a condition change condition when it is necessary to change the displayed zapping advertisement data according to advertisement scheduling. In this case, the condition detection unit 310 may detect the condition change condition at preset time intervals.

In another embodiment, when a user reserves a broadcast program through a broadcast reservation application, the broadcast reservation application of the broadcast reception device 300 may generate various command signals for processing the reserved broadcast, and a condition detector 310 may determine a command signal generated when the broadcast reservation application is executed as a condition change condition. That is, according to the execution of the broadcast reservation application, a specific broadcast program may be displayed as broadcast content, and zapping advertisement data arranged in the corresponding broadcast content may be displayed.

According to an embodiment, when the condition change condition is a user's manipulation action, the condition detection unit 310 may detect the condition change condition by receiving an operation signal from a remote control or a display device. In addition, the condition detection unit 310 may receive various signals from the broadcast content providing server 100 or the zapping advertisement server 200 to detect a condition change condition, such as information on broadcast content or information on zapping advertisement. When a change of is occurred, it can be detected as a condition change condition by receiving a change signal.

The information acquisition unit 320 may acquire broadcast content information from the broadcast content providing server 100 or zapping advertisement material information from the zapping advertisement server 200 according to the condition change condition.

Here, the broadcast content information may include identification information and additional information on broadcast content (eg, channel information of broadcast content, schedule time information, etc.). The zapping advertisement material information may correspond to which zapping advertisement is to be displayed, that is, identification information on the zapping advertisement data. In the present invention, as the simplest information for identifying a zapping advertisement according to the detection of a state change condition, the zapping advertisement material information is first obtained, and it is first determined whether all zapping advertisement data to be displayed on the display screen is recorded in the storage unit.

The storage unit 330 may store zapping advertisement data. In the present invention, the storage unit 330 includes a plurality of storage areas, and may include, for example, a first storage area 331 and a second storage area 332. Storage areas included in the storage unit 330 may have different storage characteristics, for example, storage space capacity, data transmission speed, and access speed. For example, the first storage area 331 may have a fast access speed, while the second storage area 332 may have a relatively slow access speed, and the first storage area 331 may contain data that was stored when power was cut off. All of the data are lost, but the second storage area 332 may retain all of the stored data even when the power is cut off.

In one embodiment, the first storage area 331 may be configured as a volatile memory, and data is lost when power is lost, for example, such as a dynamic random access memory (DRAM) or static RAM (SRAM). It may be a storage area with a fast access speed. The second storage area 332 may be formed of a nonvolatile memory, for example, flash memory, magnetic RAM (MRAM), phase-change RAM (PRAM), ferroelectric RAM (FeRAM). And the like. The second storage area 332 preserves data even when power is cut off, but has a relatively slow access speed and low degree of integration.

According to an embodiment, an integrated program for management of the broadcast reception device 300 may be installed in the second storage area 332. Accordingly, one partitioned storage area of the storage unit 330 may be managed as a storage area for zapping advertisement data only, regardless of a broadcast application.

In the present invention, zapping advertisement data may be stored in a plurality of storage areas constituting the storage unit 330 in different ways according to a storage policy. In an embodiment, the storage unit 330 may store zapping advertisement data in at least one of the first storage area 331 and the second storage area 332 according to the storage policy, or the first storage according to the storage policy. The zapping advertisement data may be deleted from the area 331 or the second storage area 332.

In the present invention, the storage policy is the first storage area in consideration of the size of the zapping advertisement data, the frequency of arrangement of the zapping advertisement data, the initial storage time of the zapping advertisement data, the frequency of exposure of the zapping advertisement data, the exposure time of the zapping advertisement data, etc. It refers to determining the storage target zapping advertisement data to be stored in 331 or the second storage area 332, or determining the deletion target zapping advertisement data to be deleted from the first storage area 331 or the second storage area 332.

The control unit 340 searches whether zapping advertisement data corresponding to the zapping advertisement material information exists in the storage unit 330, but sequentially assigns priority to a plurality of storage areas constituting the storage unit 330. You can search whether or not zapping advertisement data is stored. The control unit 340 may display zapping advertisement data on a second plane (eg, a background plane) visually located below a first plane (eg, a video plane) in which broadcast content is displayed according to the search result. have.

In one embodiment, the control unit 340 first searches whether there is zapping advertisement data corresponding to the zapping advertisement material information from the first storage area 331 configured with a volatile memory having a high access speed and/or a high transmission speed. And, if the corresponding zapping advertisement data does not exist in the first storage area 331 as a result of the search, it is possible to search whether the corresponding zapping advertisement data exists in the second storage area 332 configured with a nonvolatile memory.

When the zapping advertisement data does not exist in both the first storage area 331 and the second storage area 332, the control unit 340 may receive the zapping advertisement data from the zapping advertisement server 200. The control unit 340 may transmit a query requesting zapping advertisement data for a specific zapping advertisement material to the zapping advertisement server 200 and receive zapping advertisement data in response thereto.

In this case, the controller 340 may store the zapping advertisement data received according to the storage policy in at least one of the first storage area 331 and the second storage area 332. According to an embodiment, the first received zapping advertisement data may be first stored in the first storage area 331 according to a priority given when searching. In another embodiment, the zapping advertisement data received from the zapping advertisement server 200 includes zapping advertisement data information and additional zapping advertisement information (e.g., a broadcast channel in which a zapping advertisement is to be provided, an advertisement time period in which a zapping advertisement is provided, a zapping advertisement). May include the expiration date of, the advertiser information of the zapping advertisement, etc.). According to the storage policy, the control unit 340 may display the corresponding zapping advertisement data with a high frequency based on future zapping advertisement programming, or when the zapping advertisement corresponds to a zapping advertisement arranged in a user's preferred channel, or when the validity period of the zapping advertisement is long The zapping advertisement data may be stored in the first storage area 331 according to a priority given based on the like.

In this case, the controller 340 may store the zapping advertisement data received according to the storage policy in at least one of the first storage area 331 and the second storage area 332. In one embodiment, the control unit 340 uses the received zapping advertisement data based on future zapping advertisement programming, when the corresponding zapping advertisement data is displayed with a large frequency or corresponds to a zapping advertisement arranged in a user's preferred channel, or When a zapping advertisement has a long validity period or when a storage area is previously designated in the zapping advertisement data itself, the zapping advertisement data may be controlled to be stored in the first storage area 331 configured with a volatile memory accordingly.

The control unit 340 uses the zapping advertisement data obtained in step S420 or S440 to a second plane (eg, a background plane) visually located below a first plane (eg, a video plane) on which broadcast content is displayed. It can be displayed in (S450). In this case, the zapping advertisement data displayed on the second plane is not exposed to viewers by broadcast content displayed on the first plane in general. However, when a channel is changed due to input of a channel switching signal, etc., broadcast content may not be temporarily displayed on the first plane, and in this case, a zapping advertisement displayed on the second plane is exposed.

However, when the above-described channel viewing condition is detected, such as watching a specific channel while the user changes the channel past this state, broadcast content is exposed through the display device in response to the condition change condition including the channel viewing condition. While it is being performed, the zapping advertisement data may be changed and displayed in advance on the second plane (eg, the background plane).

Even if the zapping advertisement data is changed, the process of changing the zapping advertisement data is not exposed because the broadcast content is already displayed on the visual upper part, so that the zapping advertisement data can be efficiently provided to the user without feeling inconvenient, and the zapping advertisement data When changing to, since the information of the broadcast content has already been changed and processed, the load of signal processing can be minimized. And above all, according to the present invention, zapping advertisement data having a fast access speed and a high exposure frequency is stored in the first storage area 331, and the zapping advertisement data corresponding to the broadcast content by searching the first storage area 331 in advance. There is a high possibility that you can acquire. And even if this is not the case, there is a possibility that the zapping advertisement data stored in the second storage area 332 may be displayed, so that the need to increase the network load by querying the zapping advertisement data to the zapping advertisement server 200 is reduced. .

Accordingly, it is possible to prevent screen flicker that occurs in a method of receiving and exposing zapping advertisement data for a short blank time as in the prior art, and consumption of too much resources generated to expose the zapping advertisement data during a short blank time and The computational process can be reduced, and the problem of increasing the time required to expose zapping advertisement data can also be solved.

The control unit 340 may detect that the zapping advertisement data displayed on the second plane is exposed and generate advertisement exposure information including the number of exposures and the exposure time for the zapping advertisement data (S460). According to an embodiment, the controller 340 counts the channels that have moved according to the channel change signal, but the moved channels may be limited to the channels that have been viewed. That is, channels that move in the middle without meaning are not counted as viewed channels, and accordingly, zapping advertisement data is counted as being continuously exposed. Specifically, a viewer may transmit a channel change signal to the broadcast reception device 300 by inputting a channel increase button through a remote control in order to move to channel 23 while watching channel 15. The broadcast receiving device 300 moves to channel 16 according to the channel switch signal, but receives the channel switch signal again before the preset time elapses, moves to channel 17, and switches the channel again before the preset time elapses. Receives a signal and moves to channel 18, channel 19, channel 20, channel 21, channel 22, and channel 23. Therefore, in these cases, although a number of channel movements occur eight times according to the channel switching signal, the channel viewing condition is not satisfied, and accordingly, the zapping advertisement data arranged for channel 15 is counted as being continuously exposed. Then, if the channel switch signal is not input for a preset time when it reaches channel 23, it is determined that the viewer is watching channel 23, that is, it is determined that the channel viewing condition is satisfied, and the zapping advertisement data corresponding to channel 23 is displayed on the second plane. can do. Here, the viewing channel includes only channels 15 and 23, and it may be counted that a zapping advertisement corresponding to channel 15 is exposed once through a single channel change. In order to determine that the viewer is watching a channel according to an embodiment, a preset time at which the channel switching signal is not received may be determined in the range of 3 seconds to 4 seconds.

According to an embodiment, the exposure time may correspond to a time when channel 23 is displayed outside of channel 15.

According to an embodiment, the control unit 340 may determine whether to change the storage state of the zapping advertisement data stored in the first storage area 331 and the second storage area 332 based on the advertisement exposure information according to the storage policy. Yes (S470). The controller 340 may change the storage state according to a preset period, perform the corresponding step by an external command, or in response to detecting a state change condition.

According to an embodiment, the controller 340 may determine whether to move and store the zapping advertisement data stored in the first storage area 331 to the second storage area 332 based on the advertisement exposure information. For example, zapping advertisement data that does not satisfy the required exposure frequency for the zapping advertisement data stored in the first storage area 331 is moved to the second storage area 332 and stored, or the first storage area 331 When a certain period of time elapses after the initial storage in the device, it may be moved to and stored in the second storage area 332, or may be moved to and stored in the second storage area 332 when a certain period of time elapses after the last exposure. have.

According to an embodiment, the controller 340 may determine whether there is a storage space to store the zapping advertisement data by moving it to the second storage area 332. If there is no storage space for storing zapping advertisement data in the second storage area 332, the controller 340 may determine the zapping advertisement data to be deleted from the second storage area 332 according to the storage policy. In a similar manner, the control unit 340 uses zapping advertisement data that has passed a certain period of time after being stored in the second storage area 332, zapping advertisement data that has passed a certain period of time since the last exposure, or a preset reference frequency. The zapping advertisement data that does not satisfy the value or the zapping advertisement data whose validity period has expired may be deleted from the second storage area 332.

According to an embodiment, zapping advertisement data stored in the second storage area 332 may be selectively deleted according to a user's selection.

In the present specification, the zapping advertisement data to be stored to be stored in the first storage area 331 or the second storage area 332 is determined, or the zapping advertisement to be deleted to be deleted from the first storage area 331 or the second storage area 332 All policies for determining data or for determining moving zapping advertisement data stored in the first storage area 331 to the second storage area 332 are included. In an embodiment, the storage policy may determine the zapping advertisement data to be stored or the zapping advertisement data to be deleted using at least one of the number of exposures and the exposure time of the zapping advertisement data included in the advertisement exposure information.

Similar to the above, in determining the zapping advertisement data to be stored according to the storage policy, the control unit 340 compares the number of exposures generated with respect to the zapping advertisement data stored in the first storage area 331, and the number of exposures is The small zapping advertisement data may be moved to the second storage area 332 and determined as storage target data to be stored. Alternatively, the control unit 340 compares the exposure times generated for the zapping advertisement data stored in the first storage area 331, moves to the second storage area 332 in the order of the oldest exposure time, and determines the storage target data to be stored. I can. In addition, in determining the zapping advertisement data to be deleted according to the storage policy, the control unit 340 compares the number of exposures generated with respect to the zapping advertisement data stored in the second storage area 332, and compares the number of exposures generated to the zapping advertisement data with a small number of exposures. The data to be deleted from the second storage area 332 may be determined. Alternatively, the controller 340 may compare the exposure times generated for the zapping advertisement data stored in the second storage area 332 and determine the data to be deleted from the second storage area 332 in the order of the oldest exposure time. have. In addition, the control unit 340 may set a storage policy by setting a priority or weight, etc. to the number of exposures and exposure time, and the number of exposures generated for zapping advertisement data stored in the first storage area 331 according to this storage policy, and Storage target data to be stored by moving to the second storage area 332 may be determined based on the exposure time, or deletion target data to be deleted from the second storage area 332 may be determined. In addition, the control unit 340 may set a storage policy to determine the zapping advertisement data to be stored or the zapping advertisement data to be deleted periodically or according to a preset time.

According to an embodiment of the present invention, since the first storage area 331 and the second storage area 332 can be simultaneously utilized, the limitation on storage space is overcome and the efficiency of the storage space according to data storage and deletion is improved. I can make it. In addition, depending on the embodiment, a plurality of first storage areas 331 made of volatile memory may be configured in consideration of storage space and cost.

In addition, the broadcast receiving device 300 according to an embodiment of the present invention includes a first storage area 331 composed of a volatile memory, which has a higher transmission speed and an access speed than the second storage area 332 which is a storage device composed of a non-volatile memory. ), it is possible to reduce the load on the storage device by reducing the number of times the second storage area 332 is accessed. In addition, the storage unit 330 can perform a caching role by determining the storage target data to be moved to and stored in the second storage area 332 and the data to be deleted from the second storage area 332 based on the advertisement exposure information. , It is possible to reduce the number of times of downloading zapping advertisement data from an external server (zapping advertisement server), and further reduce the network load.
