FIG. 5 is a block diagram illustrating an exemplary embodiment of a detailed configuration of the controller of FIGS. 2 to 4.

Examples of the control unit may include a demultiplexer 510, an image processor 5520, an on-screen display (OSD) generator 540, a mixer 550, a frame rate converter (FRC). 555, and a formatter 560. In addition, although not shown, the controller may further include a voice processor and a data processor.

The demultiplexer 510 demultiplexes an input stream. For example, the demultiplexer 510 may demultiplex the input MPEG-2 TS video, audio, and data signals.

The video decoder 425 decodes the demultiplexed video signal, and the scaler 435 scales the resolution of the decoded video signal so that the display unit can output the resolution.

The image decoder 525 may support various standards. For example, the video decoder 525 performs the function of the MPEG-2 decoder when the video signal is encoded in the MPEG-2 standard, and the video signal is encoded in the Digital Multimedia Broadcasting (DMB) method or the H.264 standard. In this case, the function of the H.264 decoder can be performed.

For example, the frame rate converter 555 may convert the frame rate of the input 60Hz image to have a frame rate of, for example, 120Hz or 240Hz according to the output frequency of the display unit. As described above, various methods may exist in the method of converting the frame rate. For example, when the frame rate converter 555 converts the frame rate from 60 Hz to 120 Hz, the frame rate converter 555 inserts the same first frame between the first frame and the second frame or predicts the first frame from the first frame and the second frame. It can be converted by inserting three frames. As another example, when converting the frame rate from 60 Hz to 240 Hz, the frame rate converter 555 may insert and convert three more identical or predicted frames between existing frames. On the other hand, when no separate frame conversion is performed, the frame rate converter 555 may be bypassed.

The formatter 560 changes the output of the input frame rate converter 555 to match the output format of the display unit. For example, the formatter 560 may output R, G, B data signals, and the R, G, B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS. Can be. In addition, when the output of the input frame rate converter 555 is a 3D video signal, the formatter 560 may support a 3D service through the display by configuring the output in a 3D form according to the output format of the display.

The voice processing unit (not shown) in the controller may perform voice processing of the demultiplexed voice signal. The voice processor (not shown) may support processing of various audio formats. For example, even when a voice signal is encoded in a format such as MPEG-2, MPEG-4, AAC, HE-AAC, AC-3, BSAC, etc., a decoder corresponding thereto may be provided.

Also, the voice processing unit (not shown) in the controller may process base, treble, volume control, and the like.

The data processor in the control unit (not shown) may perform data processing of the demultiplexed data signal. For example, the data processor may decode the demultiplexed data signal even when it is encoded. Here, the encoded data signal may be EPG information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel.

On the other hand, the above-described digital device is an example according to the present invention, each component may be integrated, added, or omitted according to the specifications of the digital device that is actually implemented.

On the other hand, the control means such as the remote control 610, pointing device 620, keyboard 630, the touch pad as necessary, more convenient and various control purposes, such as text input, pointer movement, zooming in / out of pictures and videos Can be used for

Therefore, in the present specification, a user who wants to control a digital device through a control means recognizes the state (mode) of the digital device so that the user can control the error more quickly and conveniently without an unnecessary process. .

Hereinafter, in the digital device, the second service data is generated based on the first service data received from the first server, and the third service data is received from the second server based on the generated second service data and provided to the user. Process and a service system therefor will be described in more detail.

In the above description, the first to third service data and the first to second servers will be described in more detail in the following embodiments.

In the present specification, through such a service system, for example, an item that is most interested in view of a viewer who is watching a broadcast program may be provided through a real-time popular search term provided by a portal service company, and the corresponding popularity may be provided. It extracts the search terms related to the current viewer rating among the search terms and determines that the users who are using the corresponding digital devices will be most interested in the probability, and transmits the search terms to the server providing the advertisement content. Through this, when an advertisement request is received from the device, the server may increase an advertisement hit ratio of the device user by transmitting an advertisement for a related product based on the search terms received so far.

Through this, the advertiser can judge the actual needs of the advertisements of the actual users, and can select and concentrate or improve the product advertisement based on this, and in the end, promote the product sales through the above advertisement.

In addition, from the digital device user's point of view, it is possible to easily access advertisements for items of interest and to quickly and easily obtain information on recent trends and latest products.

Hereinafter, various embodiment (s) of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 7 is a diagram illustrating a first embodiment of a service system, FIG. 8 is a diagram illustrating a second embodiment of a service system, and FIG. 9 is a diagram illustrating a third embodiment of a service system. FIG. 10 is a diagram for describing a service processing process in the service system of FIGS. 7 to 9.

The service system of FIG. 7 includes a digital device 710, a portal server 722, and an advertisement server 724, and the service system of FIG. 8 includes a digital device 810, a portal server 822, and a content / SNS server ( 824, and the service system of FIG. 9 includes a digital device 910, a portal server 922, an advertisement server 924, and a content / SNS server 926.

Here, although some components in FIG. 7 to 9 have the same reference numerals although the names are the same, this is for convenience of description and may be the same component.

Hereinafter, embodiments of the service system of FIGS. 7 to 9 will be described with reference to the service processing process of FIG. 10.

In FIG. 10, the advertisement server, the content server, and the SNS server are described as one component, but may be individual components as shown in FIGS. 7 to 9.

The digital device is paired with one or more servers for data transmission and reception (S1002 / S1004).

In FIG. 10, although the digital device is sequentially paired with each server as in steps S1002 and S1004. However, in some cases, the digital device may perform a pairing process simultaneously with a plurality of servers or all servers.

Alternatively, unlike FIG. 10, the digital device may first pair with the portal server and then perform a pairing process with the advertisement / content / SNS server at a later point in time.

Meanwhile, the subject of the pairing process is a digital device, which determines the wired / wireless network which is available at the current location or the current time, and pairs with all servers that can be connected through all available wired / wireless networks based on the determination result. You can try

The pairing may be performed when the digital device transmits pairing request data to each server through a wired or wireless network, and each server responds to the pairing request of the digital device. In the pairing process, an authentication procedure or a log-in procedure may be required for whether the digital device has a legitimate authority with respect to the network and the server.

On the other hand, the digital device categorizes the network list of the networks available for the pairing process and / or the server list of the servers that can be connected through the networks in a predetermined unit and provides them on the screen. You can also pair only with a network or server.

In addition, in providing the network list or the server list, the digital device may recommend the network or the server and / or perform the connection and pairing automatically based on the network state or the server state. For example, a digital device pre-registers a network or server according to default or preset, and pairs directly with a server registered through the registered network when the digital device is powered on or requested by the user. You can also do Here, if there is a problem in the registered network or server status, it may be recommended based on network traffic or compatibility with the server, or may be paired with the corresponding server through the corresponding network. Conversely, the digital device may be configured to exclude a specific network or / and a specific server from pairing or transmitting and receiving data to be described later regardless of the network state or the server state.

When the digital device is paired with the portal server, the digital device receives first service data from the paired portal server (S1006).

Here, the first service data includes portal server data, and the portal server data includes, for example, real-time popular search word data generated by the corresponding portal server.

In addition, the real-time popular search word data is composed of various data formats. For example, the real-time popular search term data provided by the portal server may have an xml form. However, the format of the real-time popular search term data is not limited thereto, and may include all types of data types such as streaming forms, audio / video forms, image forms such as thumbnail images, or text forms. The form may be a combined form.

Meanwhile, if the above-described first service data is portal server data and is real-time popular search term data, the first service data includes data on search term ranking, search term category, search term, search term ranking change, time, etc. as items. Data may be provided. In addition, the keyword ranking change data in the above may be affected by various parameters such as ranking rise, rank fall, newly included in the rank, ranking rise, rank descent.

The first service data may be continuously transmitted at a predetermined period or aperiodic period after pairing with the digital device in the portal server.

In particular, the latter aperiod includes a case where the case is transmitted when there is a change in at least one item constituting the real-time popular search word data included in the first service data. For example, the ranking of at least one search term among the search term items constituting the real-time popular search term data may be changed, a new search term may be added, or a specific search term may rise or fall above a predetermined range, or may fall below a predetermined range. Therefore, when there is an event, that is, at least one real-time popular search term data item has changed, the portal server transmits the latest real-time popular search term data updated with the previous data back to the digital device. Such a change is information based on the interest of a plurality of portal users and the like, even if a digital device user cannot use the corresponding portal server or portal site. It is desirable to send to the user.

Meanwhile, the first service data may be transmitted only when a data transmission request is made from the digital device to the portal server.

In the above, the request may be made in various ways.

For example, when a user is running a web browser, the first service data may be requested by selecting a specific item on a web page provided by the corresponding portal server. In this case, the digital device may provide the received first service data through a web browser.

Alternatively, when a user accesses a specific button and calls a predetermined function through the control means of the digital device, first service data may be requested to the portal server in response to the specific button or the predetermined function.

On the other hand, the control means of the digital device is, for example, a pointing device or a motion remote controller, and a user can select a predetermined object or item from the content provided by the digital device on the screen. When the user selects or calls a menu, a function, or the like, the first service data may be requested to the portal server.

In this case, the digital device may extract data related to an object, an item, a menu, a function, etc. selected or called by the user, and request the first service data from the portal server.

Accordingly, the digital device may receive first service data related to an object, item, menu, function, etc. selected or called from the portal server and provide the same to the user.

In addition, the first service data request may be automatically made in the playback, channel change or tuning, time, etc. of specific content set through an electronic program guide (EPG) or the like called according to a user's request on a digital device. have.

For example, the digital device requests the first service data from the portal server whenever the channel A is tuned according to a preset setting, or the first service data is transmitted to the portal server when viewing a certain category of content such as news or drama. You can request Alternatively, the digital device may request the first service data from the portal server in a predetermined time unit, that is, every 30 minutes or every hour.

Meanwhile, in the transmission of the first service data, as described above, the portal server may transmit all of the real-time search word data generated in advance, and may correspond to a selection or request of a digital device from the generated real-time search word data. Only the query data may be filtered and transmitted.

When the first service data is received from the portal server through step S1006, the digital device outputs the first service data to a predetermined area on the screen and generates second service data based on the received first service data (S1008).

In the above, the digital device outputs the first service data received from the portal server to a predetermined area on the screen, and may refer to the attribute or OSD data of the content currently provided on the screen.

Except for certain cases, digital devices generally generate OSD data for them in outputting content on the screen. Accordingly, the digital device may determine the output area of the first service data received from the portal server with reference to the OSD data for the currently provided screen. For simplicity, the digital device may output a blank area in which OSD content is not output in the OSD data. However, if the digital device determines that the content is output to all areas of the screen as a result of determining the OSD data, the priority of each area is determined based on the content property, etc., so that the area having a lower priority than the other areas is sacrificed. The first service data may be controlled to be output on the content of the corresponding area.

In addition, the digital device may control the first service data to be provided only temporarily in a pop-up form or continuously provided to a predetermined area for a predetermined time.

Next, the digital device generates second service data. Here, the second service data includes all the information generated in the digital device for receiving, for example, data that is more suitable for the user's needs or interests from the related server or the like, that is, the third service data.

The second service data may be generated based on the received first service data or may be generated by further including or combining additional information in the first service data. In the above description, the additional information may refer to information previously stored in a digital device, and the electronic program guide (EPG) is an embodiment.

The second service data is generated in the process of searching for the item information that is most influential or of interest to the user by extracting a common factor between the received first service data and the EPG information. As described later, the data map may be implemented.

For example, the most suitable advertisement category and main keyword are selected from the real-time popular search term information and EPG information, that is, the program list data for correction, which is most suitable for the user who is currently watching or consuming the digital device. Here, it is preferable that the popular search word service server also transmits category information about the search word.

The second service data may include various data according to various criteria.

For example, when the second service data is configured, the second service data may be weighted on items having a high search rank increase rate among search terms, may be individually weighted for each search rank rank, or may be individually weighted according to the search rank rank increase rate step. Can be. Alternatively, the second service data may select a category that may be a product and other advertisement targets among search term categories. For example, after the advertisement-related category is preset and stored in the internal data of the digital device, the search word XML data in the first service data received is compared with the character.

Alternatively, the second service data may be configured by comparing the channel and program names tuned by the digital device at the current time with the search word character in the first service data and correcting them based on the EPG data. For example, if you are watching a program called OnGameNet via a digital device, the weights are based on whether the game words in the search term category and the game words on the OnGameNet match or are compared to other channel information and included or matched as a result. If not individually or if there is no case may not be assigned a weight.

Alternatively, a list suitable for an advertisement product may be extracted from existing popular search term data, and the map data (Map data.xml) in XML format may be generated by adding a weight value determined to a rank for each search term. In this case, the category information may be adjusted first or secondly to increase or decrease the matching rate.

Ad Rank category Advertiser Control One game Diablo 3 2 Enterprise Kupang 3 Enterprise 11th Avenue

The map information configured as shown in Table 1 may be configured as second service data and transmitted to the advertisement server to request an advertisement.

Therefore, the advertisement server may determine the advertisement list according to <rank> <category> <advertising keyword> among the advertisement lists to be sent and transmit the corresponding advertisement list to the digital device. In this case, if there is no match item, the advertisement data, which is transmitted most frequently for the category or the advertisement keyword, which is generally sent, may be transmitted as the third service data to the digital device.

When the second service data is generated using only the first service data, the digital device generates second service data depending on the first service data, and thus will be described later based on the second service data. The third service data provided may receive data that has nothing to do with content currently being viewed on the digital device. In other words, the generated second service data may be generated for the interests of ordinary people at the time of receiving the first service data.

In contrast, in the case of generating the second service data using EPG information, in the former case, although the interests of the general people are reflected, the needs or interests of the user of the corresponding digital device may be neglected. By combining the second service data generated according to the electronic scheme. Here, the correction means, for example, the target suitability of the third service data to be described later, that is, to correspond more to the needs or interests of the user of the corresponding digital device.

For example, the digital device extracts data such as a channel, a program name, and the like of the program currently being viewed on the screen from the EPG information. The digital device generates a list of data that is related to the extracted data with respect to the first service data or that is higher than or equal to a predetermined level. The digital device generates second service data by referring to the relevant data list.

Alternatively, in the latter case, the digital device may generate second service data by further combining thumbnail image data in place of or in addition to the EPG information. Here, the thumbnail image data may be a capture screen of a channel or content currently being viewed, or may be a preview image or a thumbnail image included in the EPG information.

The digital device transmits the second service data generated through the step S1008 to the advertisement / content / SNS server (S1010).

Here, the transmission of the second service data from the digital device to the advertisement / content / SNS server may be performed, for example, by the user's screen switching (ex, home, premium service screen, etc.).

The advertisement / content / SNS server collects third service data to be returned to the corresponding digital device based on the second service data received through the step S1010 (S1012).

Here, the advertisement / content / SNS server may establish a database in advance and collect data related to the second service data received.

The advertisement / content / SNS server selects one or more data from the collected data, generates third service data, and returns the third service data to the digital device (S1014).

The digital device decodes the third service data returned from the advertisement / content / SNS server in step S1014 and outputs the decoded third service data to a predetermined area on the screen (S1016). The digital device may provide the decoded third service data in the same or similar form as the output scheme of the first service data described above with respect to the output. In this case, the first service data and the third service data may be provided together. In addition, when decoding the third service data, the third service data may be appropriately converted.

Meanwhile, the portal server may receive second service data generated through step S1008 and third service data received through step S1014 from a digital device or an advertisement / content / SNS server.

The received second service data and / or third service data may be reflected in, for example, real-time search term ranking or search term related images, advertisements, and other data in the portal server.

FIG. 11 is a diagram illustrating a fourth embodiment of a service system, and FIG. 12 is a diagram illustrating a service processing process in the service system of FIG. 11.

FIG. 11 has a configuration similar to the above-described service system of FIGS. 7 to 9, but the cloud server 1120 is positioned between the digital device 1110 and the servers 1130 to transmit and receive data through the cloud server 1120. . Accordingly, the fourth embodiment of FIG. 11 may be particularly effective in the mobile device as shown in FIG. 3. However, it will be apparent that the present invention can be applied to other mobile devices.

Hereinafter, in the following description of FIGS. 11 and 12, the description of the overlapping parts with reference to FIGS. 7 to 10 will be described above, and the detailed description thereof will be omitted.

The digital device pairs with the portal server, the cloud server, and the advertisement / content / SNS server, respectively (S1202 to S1206).

After pairing through steps S1202 to S1206, the digital device receives the first service data from the portal server. In this case, unlike FIGS. 7 to 10 described above, when the portal server uploads the first service data to the cloud server and transmits the URL address of the first service data uploaded to the cloud server to the digital device, The first service data may be downloaded from the digital device by directly accessing the URL address.

The digital device outputs the received or downloaded first service data to a predetermined area on the screen, and generates second service data based on the first service data (S1212).

The digital device uploads the second service data generated in step S1212 to the cloud server and receives URL address data of a location where the uploaded second service data is stored from the cloud server (S1214).

The digital device transmits the URL address data returned after the second service data is uploaded to the advertisement / content / SNS server in step S1214, and the advertisement / content / SNS server accesses the transmitted URL address and uploads the uploaded URL by the digital device. 2 Download the service data (S1216).

The advertisement / content / SNS server collects data from the database based on the second service data downloaded through the step S1216 and selects one or more third service data from the received data (S1218).

The advertisement / content / SNS server uploads the selected third service data to the cloud server through step S1218, receives the URL address data storing the uploaded third service data, and transmits it to the digital device (S1220).

After the step S1220, the digital device accesses the URL address received from the advertisement / content / SNS server and downloads the third service data (S1222).

The digital device appropriately processes the third service data of the advertisement / content / SNS server downloaded through the step S1222 and outputs it on the screen (S1224).

Meanwhile, when the above-described second service data and third service data are uploaded to the cloud server, the URL address data of the data is transmitted from the digital device or the advertisement / content / SNS server to the portal server, and the corresponding URL address is transmitted from the portal server. Can be downloaded and used as described above.

In FIG. 12, the data uploaded through the cloud server is downloaded and connected to the URL address where the data is stored, not the cloud server. However, in the drawing, the data is indicated as facing the cloud server.

FIG. 13 is a diagram illustrating a fifth embodiment of a service system, and FIG. 14 is a diagram illustrating a service processing process in the service system of FIG. 13.

FIG. 13 is similar to the above-described service system of FIGS. 7 to 9 or the service system of FIG. 10, but the service server 1320 is located between the digital device 1310 and the servers 1390, through the service server 1320. Data transmission and reception are different.

First, the configuration of the service system of FIG. 13 will be described.

FIG. 13 is a block diagram illustrating a service system including the first server 1320 and the second server 1390 as described above. Hereinafter, the configuration of the service server 1320 will be described in more detail.

Here, the first server 1320 is a service server, and the second server 1390 means a server including at least one or more of the portal, advertisement, content, and SNS servers illustrated in FIGS. 7 to 9 and 11.

The service system of FIG. 13 includes a digital device 1310, a service server 1320, and a second server 1390. As described above, the service server 1310 may be a server provided by the manufacturer of the digital device 1310. Although not shown, the service system of FIG. 13 may further include a cloud server.

The process of processing data between the digital device 1310 and the second server 1390 in the service server 1320 will be described in terms of the components of the service server 1320.

The service server 1320 may include a control unit 1325, a crawler module 1330, a search module 1340, a processing unit 1350, various databases 1360 and 1370, and a search engine. 1380).

Here, the service server 1320 may use only some of the components shown in FIG. 13 or may further include some components to process data. In addition, some of the illustrated components may be implemented in one module or vice versa.

The control unit 1325 receives the first service data from the second server 1390, analyzes the received first service data, and transmits the received first service data to the digital device 1310 or the first or second service through the processing unit 1350. It can be stored in the database (1360, 1370). Here, the processor 1350 may replace the function of the controller 1325 receiving the first service data. In this case, the processor 1350 may transfer the received first service data to the digital device 1310 through the controller 1325 or store the received first service data in the first or second service databases 1360 and 1370.

The control unit 1325 receives the second service data from the digital device 1310 based on the transmitted first service data and transmits the second service data to the crawler module 1330, and the crawler module 1330 passes through the processing unit 1350. The data may be stored in the first or second service databases 1360 and 1370. The processing unit 1350 receives location information, that is, URL address data including address data in which the second service data transmitted from the databases 1360 and 1370 are stored.

The processor 1350 transfers the URL address data of the returned second service data to the second server 1390.

The second server 1390 accesses the corresponding URL based on the received URL address data of the second service data, downloads and analyzes the second service data, and generates third service data based on an analysis result. It returns to the processing unit 1350 again.

When the third service data is returned from the second server 1390, the processing unit 1350 reports at least one of the control unit 1325, the crawler module 1330, and the search module 1340 (but, for convenience, reports it from the controller). The third service data may be informed that the received third service data is returned, and the third service data may be temporarily stored in the databases 1360 and 1370.

The controller 1325 extracts the temporarily stored third service data according to a report of the processor 1350 and returns the data to the digital device 1310 directly or delivers URL address data of the location of the stored third service data. The digital device 1310 controls the direct download by accessing the corresponding URL address. In this way, one function of the service server may be terminated.

The service server 1320 may be connected to a plurality of digital devices instead of only one digital device 1310. In this case, the above-described process may be repeated for each digital device.

In this regard, the controller 1325 receives the first service data and / or the third service data from the second server 1390 regardless of the request of the digital device 1310 and the like and temporarily stores them in the databases 1360 and 1370. When a request for the first service data or the second service data is received from one digital device, the processor 1350 temporarily stores the first service data in the databases 1360 and 1370 through the processor 1350.

Thereafter, the controller 1320 may control the search module 1340 to analyze and search the first service data or the third service data related to the received request for the first service data or the second service data.

The search module 1340 examines whether the received first service data request or the second service data of one digital device is the same as or similar to the request of the first service data or the second service data received from another digital device. . As a result of the review, if the same or similarities are many, the first service data or the third service data or the stored URL address data previously returned to other digital devices are extracted and returned to the corresponding digital device. Alternatively, as a result of the review, if the same or similarity of both data is below a predetermined criterion, the request or the second service data may be delivered to the second server 1390 for processing as described above.

In the case of the service system of FIG. 13, the service server 1320 functions as an intermediate link between a plurality of digital devices and a second server, and processes or combines the first to third service data as appropriate. In addition to reducing the load on the system, the data processing speed or efficiency can be maximized. In addition, the service server 1320 may process raw data provided by one digital device or a second server with reference to data of another digital device or server, thereby further enriching the data to be more suitable for user needs or interests. Data can be obtained and trends can be easily identified. In addition, the service server can additionally obtain the viewership information or other necessary information from the return data of the digital device, and the second server can secure the return of the service provided through a stable route, thereby improving the service or the needs of the user. It is easy to see the interest.

Hereinafter, in the following descriptions of FIGS. 13 and 14, descriptions overlapping with the descriptions of FIGS. 7 to 10 and 11 to 12 will be referred to above and detailed descriptions thereof will be omitted.

Unlike the above-described embodiments, the digital device only pairs with the service server (S1402). Here, the portal server and the advertisement / content / SNS server are indirectly paired through the service server.

The digital device may directly pair with at least one of the portal server and the advertisement / content / SNS server. Here, the digital device only pairs directly with the service server, but indirectly pairs with the remaining servers through the service server (S1404 and SS1406).

Accordingly, in the following, each data is transmitted and received between the digital device and another server through the service server, but is not necessarily limited thereto. For example, the portal server may directly transmit and receive first service data to and from the digital device through the same process as in the previous embodiment. Similarly, the advertisement / content / SNS server may also transmit and receive data as in the previous embodiment without passing through the service server.

After pairing through steps S1402 (S1406), the digital device requests the first service data to the portal server via the service server, and the portal server uploads the first service data to the service server in response to the request (S1408). .

In this case, the portal server may also transmit only URL address data of the location where the first service data is stored to the service server. Alternatively, the service server may store the first service data uploaded through the portal server at a predetermined location and transmit the URL address of the stored location to the digital device.

The digital device directly accesses the service server to directly download the first service data uploaded from the portal server or directly accesses the URL address received from the service server to download the first service data of the portal server (S1410).

The digital device outputs the downloaded first service data to a predetermined area on the screen and generates second service data based on the first service data (S1412).

The digital device uploads the second service data generated in step S1412 to the service server (S1414).

Here, the service server stores the second service data of the uploaded digital device and delivers URL address data for the location of the stored second service data to the advertisement / content / SNS server or directly transmits the uploaded second service data. It can be delivered to advertisement / content / SNS server.

The advertisement / content / SNS server downloads the second service data of the digital device by accessing the URL address data received from the service server (S1416).

The advertisement / content / SNS server collects data from the database based on the second service data downloaded through the step S1416 and selects one or more third service data from the received data (S1418).

The advertisement / content / SNS server directly uploads the selected third service data to the service server through step S1418 (S1420).

The service server stores the uploaded third service data in a predetermined location and transmits URL address data of the location of the stored third service data to the digital device. The digital device directly accesses the received URL address data and downloads the uploaded third service data (S1422).

The digital device appropriately processes the third service data of the advertisement / content / SNS server downloaded through the step S1422 and outputs it on the screen (S1424).

In FIG. 14, the data uploaded through the service server is downloaded and connected to the URL address where the data is stored, not the service server. However, the data is indicated as being directed to the service server for convenience.

FIG. 15 is a diagram illustrating a load balancing system that can be borrowed from the service systems of FIGS. 7 to 9, 11, and 13.

FIG. 15 may be an example of a cloud server service system borrowed or newly configured in the above-described embodiment of each service system.

Meanwhile, when only one digital device and one server are targeted in the service system process of FIGS. 7 to 9, 11, and 13 described above, there is no problem with each other. However, if you put a lot of digital devices and one server, this can be a huge load on the server side. Therefore, the server side may incur additional costs such as server expansion due to excessive traffic load, and may cause inconvenience to the user due to problems such as speed.

In relation to FIG. 15, a load balancing server 1500 as shown in FIG. 15 is disclosed so that data can be transmitted / received at predetermined intervals between digital devices and servers as one of the above-described service systems or individual service systems.

Referring to FIG. 15, the service system includes a digital device stage (1510 to n, where n is a positive integer), a load balancer stage 1500, and an image host node stage (1550 to m, m is a positive integer). It is composed.

Here, the load balancer stage 1500 and the image host node stages 1550 to m may be viewed as the server side, and the digital device stages 1510 to n may be viewed as clients.

In addition, the server may be a cloud server, which may be the cloud server of FIG. 11 described above.

The server of FIG. 15 basically uploads first service data at predetermined time intervals, and receives and uploads second service data at predetermined time intervals from each digital device terminal. Here, the predetermined time may be, for example, 10 seconds. The server may also be controlled to accept at least a predetermined number of uploads per 10 seconds. Here, the predetermined number of times may mean, for example, at least 30,000 times.

In addition, the server may upload only the latest second service data to the digital device terminals 1510 to n and download the first service data or the third service data.

In addition, the server does not need to have a permanent storage medium for storing the first to third service data. For example, since the server temporarily stores the first service data received from the digital device, the previous first service data is continuously updated in consideration of the memory capacity (the size of each first service data is 50 to 100 KB), the cost, and the like. You can delete it immediately, so you don't need to save it permanently. Thus, the server does not need to have a permanent storage medium. That is, when new data is received, the old data is no longer needed and thus deleted.

In addition, when the second service data is uploaded from a specific digital device, if the second service data received before the predetermined time exists, the server first determines whether the second service data is the same, and rejects the upload request in the same case. You may. For example, the same may be applied to other digital devices other than the specific digital device. That is, it is possible to return only the first or third service data in the future without receiving the actual second service data.

Meanwhile, the server may transmit the next upload request time in response to the rejection to the corresponding digital device as a response. Here, the next upload request time, for example, if the original upload request time was 10 seconds, may be increased by 1 second for each rejection. However, if the request time reaches a maximum of 300 seconds (5 minutes) due to the continuous rejection, it is not increased any more. In addition, the continuously increased request time may be automatically initialized when the request is permitted at a particular moment. That is, the next upload request time may be 10 seconds.

The server may group each digital device based on location, access address, user, and the like. For example, the server may be grouped based on at least one of, for example, an original network identifier, a transport stream identifier, a service identifier, a service name, and the like.

Therefore, when the server requests the third service data according to the first service data or the second service data transmission from at least one digital device in the group, the server may return the first service data or the third service data to the entire group. . It may be returned to the whole group only when at least one third or more of the digital devices request, and only to the corresponding digital devices. However, when data is received, the server may compare the data received from the corresponding group or another group and use the data for analysis. Accordingly, the server may quickly respond without performing a comparative analysis process on the second server 1390 or the advertisement data received therefrom based on the analysis result.

In addition, upload or download can also be controlled in groups.

In addition, since the digital device and the image host node in the service system may not have a one-to-one correspondence, server errors, data errors, and users may occur due to excessive load unless the control operation is performed to properly distribute data transmission and reception between each other. Problems such as complaints, system errors, etc. To this end, the server-side may further include, for example, a load balancer 1500 that performs load balancing on a group basis for each node.

The load balancer 1500 includes round robin, list connection, response time, hash, minimum missies, and bandwidth based loadbalancing. Server load balancing algorithm. Hereinafter, a hash method will be described as an example to help understanding of the present invention and for convenience of description.

Hashing is a method of load balancing using, for example, a hashing algorithm provided by Altheon itself, where the source IP creates an index for servers in a real server group. Used as Service requests to the same user connect to the same server, but can be reassigned if a service error occurs on that server, or if a real server is removed from or added to a server group . However, in the hash method, the weight option cannot be used, but the maximum connection can be supported. Therefore, load balancing is fair when there are a large number of access users.

The hash algorithm specifies a path with a hashing key for each client on a new connection (TCP / UDP). Here, the hashing key is determined only by the client's IP + port or IP address. By maintaining a session once established between clients and servers, a particular client connects only to that particular server. This method determines which server to connect to by the client's source IP address (32 bit) divided by the number of real servers.

Combine source IP and destination IP. For example, suppose you have a source IP of "192.168.1.1" and a destination IP of "10.10.10.254", and say that the source is a user and the destination is vip. The combination of these two IPs then yields some numbers. So if we combine the ending IP 1 with 254, we get a number of 255. Divide this number by the number of real servers you have set, and if there are three servers, the remainder is zero (255/3 = 85 remaining zeros). This will connect you to Real Server 1. If the combination is 124. Then the remainder divided by 3 becomes 1 (124/3 = 41 remainder 1), which is allocated to real server 2.

Then the next time you connect, the vip and client ip are the same, so the rest of the values will always be the same. Then you will always connect to the same server.

This is usually used for sites that need to maintain sessions (authentication, security, etc.). The server is chosen by the IP value generated by creating a hash table. The real server, once selected on the client side, will continue to serve one server. According to this hash method, the advantage is that the path is guaranteed, uses less memory, and the request procedure is simple.

In Fig. 15, for example, the upload IP address is' http://A2.com/lg_epg_thumbnail/post?id=dvb://233a.2f.1 & service_name = BBC1 ', and the download IP address is' http: / /A3.com/lg_epg_thumbnail/get?id=dvb://233a.2f.1 & service_name = BBC1 '.

Accordingly, the load balancer 1500 may determine a corresponding image host node by using a hash method for the combination of 3-id and service name when the digital device is connected through the above-described IP address in the upload / download process.

Meanwhile, referring to FIG. 15, the service server may additionally easily aggregate and provide viewer rating information when each image host node of the server side counts the number of uploaded data. However, at this time, a specific image host node or a separate aggregation server may be provided, and communication with each node may collect and classify viewer rating information on a specific channel or service.

16 is a flowchart illustrating a service processing process of the above-described service system.

The second service data may be generated with reference to the received first service data and EPG data stored in the digital device, and the first service data includes real-time popular search term data in xml format. The real-time popular search term data may include at least one of a search term, a search term ranking, a search term category, changes in search term ranking, and search term update time information.

In addition, the second service data may be weighted or categorized according to an item having a high search word ranking increase rate among the first service data, for each search word rank or increase rate level, and then, among the search word categories of the second service data, Identify a category to be included in the second service data in comparison with a category corresponding to an advertisement target, or compare or include a current time program, a channel and a program name included in the EPG data with a search term category of the first service data According to the present invention, the weight may be determined by further assigning a weight, and may be configured to include at least one of an advertisement rank, an advertisement category, and an advertisement keyword as a set.

Meanwhile, the first server may be a portal server, and the second server may be any one of an advertisement, content, or SNS server.

Referring to FIG. 16, the digital device pairs with one or more servers (S1602).

The digital device receives the first service data from the at least one paired server (S1604), configures the received first service data, and outputs appropriately to a predetermined area on the screen (S1606).

The digital device generates second service data based on the data selected from the received first service data or the outputted first service data (S1608).

The digital device transmits the generated second service data to at least one server (S1610).

The digital device receives third service data from at least one server based on the transmitted second service data (S1612), processes the received third service data, and outputs it on the screen (S1614).

In the present specification, the portal server, the advertisement server, the content server, and the SNS server have been described on the assumption that there is only one, but each of them may be extended to a plurality. For example, when the digital device receives the first service data from the portal server, and the portal server is plural, the digital device divides the first service data received from each of the plurality of portal servers into server units and provides the same. Alternatively, duplicates can be eliminated and provided in combination with the digital device. This principle can be applied to the second service data and the third service data as it is. Therefore, in the present specification described above, although one server or data has been described as an embodiment for convenience, the present invention is not limited thereto and can be expanded to a plurality.

Meanwhile, the second service data described above may not be generated based on the first service data, but may be generated only by data provided in the digital device.

For example, when a user accesses an item related to a predetermined content or a person through an EPG or the like, the second service data is generated based on the access and transmitted to a portal, an advertisement, a content, an SNS server, and the like. Third service data corresponding to the data may be received and provided around the accessed item.

Alternatively, when the user makes a reservation recording, a time shift, a viewing reservation through an EPG, or the like, the second service data is generated based on the user's action and transmitted to the server to receive the third service data from the server. It is saved along with transport data such as reservation recording, time shift, viewing reservation, or the like. When the digital device plays the reserved recording, the time shift, and the viewing-reserved content, the digital device outputs the third service data stored together at the appropriate time. In this case, the digital device may replace the pre-stored third service data by receiving the presence or absence of updated data and the updated data from the server in relation to the pre-stored third service data. Alternatively, when other data associated with previously stored third service data is received, the digital device may provide the received other data instead of the third service data.

On the other hand, the digital device may deliver one or a plurality of second service data through the above-described data transmission / reception scheme. For example, the digital device may transmit the plurality of first service data at one time.

In addition, the digital device may receive a plurality of third service data instead of one from the server side.

In this case, the digital device may process the third service data differently when only one third service data is received.

First, if only one third service data is received, the digital device decodes it and outputs it to a predetermined area on a screen currently being provided. In this case, if the decoded third service data is not only image data but also audio or video data, it may be appropriately processed accordingly.

However, when a plurality of third service data are received, the processing scheme may vary. Basically, the digital device may temporarily store the plurality of received third service data and ignore it without storing unnecessary or redundant third service data as compared with previously stored third service data. At this time, if necessary, the digital device may provide a plurality of pieces of third service data received to the user in the form of a list, and may discard the third service data which is previously selected or not selected even without decoding. In addition, the order of providing may be selected through the list.

The digital device may simultaneously provide the processed third service data in the form of a list (for example, a channel browser or an EPG) on the entire screen at the same time, or may be provided in a predetermined area on a screen currently being provided or sequentially output. have.

The digital device outputs the processed third service data in the form of a list at the bottom of the screen, expands and provides the entire screen or a predetermined area only when the user accesses the data, and continues to provide the list of services in the form of a list for a predetermined time. It may be.

In this case, although not shown, as described above, the digital device receives the viewer rating information from the service server according to the screen captured during the transmission of the second service data, and together with or separately from the first or third service data. It can also be processed and provided on the screen.

In addition, when a plurality of third service data are received from a plurality of servers, the digital device may process the respective pieces of data by the server unit. Here, the plurality of servers may mean a service server and different advertisement servers.

On the other hand, the digital device processes the classification according to the attribute or type of the transmitted third service data, for example, whether the third service data is information on a current product, information on a recommended product, or information on predetermined content on the screen. You may.

Next, the utilization of the third service data received and provided by the digital device or the additional service related thereto will be described.

For example, the third service data may not only provide image data about recommended advertisement data but may also include purchase information and the like in order to maximize an advertisement effect when it is selected by a user. Here, the purchase information refers to information necessary for the user's purchase, such as the homepage of the company providing the advertisement, the contact information, location information on nearby vendors based on the location information of the current digital device, and the contact information of the seller. For this purpose, a web browser or the like may be executed separately.

In addition, when the user accesses the output of the third service data, the digital device may ask for the user's intention and provide recommendation or non-recommendation feedback information about the advertisement, whether to accept the update of the regular or irregular advertisement data, and the like. Update information may also be received. In this case, the advertisement server may be used to change advertisements based on the feedback information of the user, and may provide other event information such as purchase information and discount information to the feedback user or the corresponding digital device together with the third service data.

In addition, when the user accesses the third-party service data output, the digital device may provide recommendation / deprecated feedback by interworking with SNS or by interworking with a cafe or webpage related to a corresponding advertisement product on SNS or the web. It may also provide a convenience for purchase according to the advertisement.

Alternatively, when the user accesses the third-party service data output, the digital device provides an advertisement home page, downloads software / firmware already purchased or necessary for purchase, receives a repair request if necessary, product failure or usage, etc. Various user request processing may be provided so that it can be processed immediately without a separate operation.

In the meantime, when the third service data includes or is able to provide the related content, the digital device may provide the content according to the user's access to the third service data and may provide the content according to the user's selection.

In addition, when the digital device accesses the third service data, the digital device may be provided with an automatic check or error resolution information about an error on the previously purchased device.

Meanwhile, in providing the third service data according to the connection of the external device, the digital device provides the third service data being provided when the digital device is turned off or the connection of the external device is released. It may be provided continuously, or may be provided at the user's request that it has been temporarily stored. In the latter case, the third party may provide unconfirmed third party service data in a pop-up form only when the digital device is powered on or when the corresponding external device is reconnected, and may be immediately deleted without being provided or stored at the user's option.

Meanwhile, in the present specification, the advertising data is mainly described, but various contents other than the advertising data may be transmitted and received between the digital device and the servers. This mainly depends on the property or data configuration of the second service data, but the service configuration to the third service data configuration can be completely different by contacting the content server or the SNS server instead of the advertisement server.

For example, when a movie content server is contacted instead of an advertisement server, the content server is based on the second service data, and the content server may include the latest movie list, the movie list with a large number of viewers, the movie list with a high rating, the domestic / international movie list, and the genre. When the list of movies is first sent and a payment is made by accessing a payment server or the like according to a user's selection of a digital device, the corresponding movie content may be provided.

Alternatively, if the SNS server, based on the second service data of the digital device, it may recommend to the currently active account or provide to monitor some or all of the relevant SNS service data.

In this case, when the third service data is not only advertisement data but also predetermined content or SNS data, the related function may be automatically called according to the type or attribute of the received third service data. For example, if preview data of movie content is received, the video playback player is automatically called to provide a preview image in a predetermined area of the screen, or if SNS data, a window for SNS service is called and a separate log-in procedure is performed. By performing the preparatory procedure or preliminary work for using the service.

According to the present invention described above, it is possible to provide an adaptive service according to the user response of the digital device based on the data received from the server, and not to simply receive passive advertisement data passively but to the item of interest to the user. Actively receive advertising data to improve user's satisfaction and maximize the advertising effect of advertisers.In addition to providing simple advertising data, various related services can be linked to provide useful information to users. Product satisfaction of the digital device that provides the can also increase the user's desire to purchase.
