2 is a block diagram of a digital TV according to an embodiment of the present invention.

The digital TV 200 includes a network interface 201, a TCP / IP manager 202, a service delivery manager 203, an SI decoder 204, A demultiplexer or demultiplexer 205, an audio decoder 206, a video decoder 207, a display A / V and OSD module 208, a service management manager 209, a service discovery manager 210, an SI & metadata DB 211, a metadata manager 212, a service manager 213, A UI (User Interface) manager 214, and the like.

The network interface unit 201 transmits the IP packet (s) (IP packet (s)) or the IP datagram (s) ) From the server 105 or transmits it to the server 105. For example, the network interface unit 201 may receive a service, application, content, and the like from a service provider through a network.

The TCP / IP manager 202 analyzes the IP packets received by the digital TV 200 and the IP packets transmitted by the digital TV 200, that is, the packet transfer between the source and the destination packet delivery). The service discovery manager 210, the service control manager 209, the meta data manager 212, the service discovery manager 210, the service control manager 209, and the metadata manager 212. The TCP / IP manager 202 classifies the received packet (s) ) Or the like.

The service delivery manager 203 is responsible for controlling the received service data. For example, the service delivery manager 203 may use RTP / RTCP when controlling real-time streaming data. When the real-time streaming data is transmitted using the RTP, the service delivery manager 203 parses the received data packet according to the RTP and transmits the packet to the demultiplexing unit 205 or the control of the service manager 213 In the SI & meta data database 211. [ Then, the service delivery manager 203 feedbacks the network reception information to the server providing the service using the RTCP.

The demultiplexer 205 demultiplexes the received packets into audio, video, SI (System Information) data, and transmits them to the audio / video decoder 206/207 and the SI decoder 204, respectively.

The SI decoder 204 decodes the demultiplexed SI data, that is, Program Specific Information (PSI), Program and System Information Protocol (PSIP), Digital Video Broadcasting Service Information (DVB-SI), Digital Television Terrestrial Multimedia Broadcasting / Coding Mobile Multimedia Broadcasting). Also, the SI decoder 204 may store the decoded service information in the SI & meta data database 211. The stored service information can be read out and used by the corresponding configuration, for example, at the request of the user.

The audio / video decoder 206/207 decodes each demultiplexed audio data and video data. The decoded audio and video data is provided to the user through the display unit 208.

[ In other words, the application manager can manage the overall state of the digital TV 200, provide a user interface (UI), and manage other managers.

The UI manager 214 provides a GUI (Graphic User Interface) / UI for a user using an OSD (On Screen Display) or the like, and receives a key input from a user to perform a device operation according to the input. For example, the UI manager 214 receives the key input regarding the channel selection from the user, and transmits the key input signal to the service manager 213.

The service manager 213 controls the manager associated with the service such as the service delivery manager 203, the service discovery manager 210, the service control manager 209, and the metadata manager 212. In addition, the service manager 213 generates a channel map and controls the selection of a channel using the generated channel map according to a key input received from the UI manager 214. [ The service manager 213 receives the service information from the SI decoder 204 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 205. The PID thus set can be used in the demultiplexing process described above. Accordingly, the demultiplexer 205 filters (PID or section) audio data, video data, and SI data using the PID.

The service discovery manager 210 provides information necessary for selecting a service provider that provides the service. Upon receiving a signal regarding channel selection from the service manager 213, the service discovery manager 210 searches for the service using the information.

The service control manager 209 is responsible for selection and control of services. For example, the service control manager 209 uses IGMP or RTSP when a user selects a live broadcasting service such as an existing broadcasting system, and selects a service such as a video on demand (VOD) , RTSP is used to select and control services. The RTSP protocol may provide a trick mode for real-time streaming. In addition, the service control manager 209 can initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

The metadata manager 212 manages the metadata associated with the service and stores the metadata in the SI & metadata database 211.

The SI & meta data database 211 stores service information decoded by the SI decoder 204, meta data managed by the meta data manager 212, and information necessary for selecting a service provider provided by the service discovery manager 210 . In addition, the SI & meta data database 211 may store set-up data for the system and the like. The SI & meta data database 211 may be implemented using a non-volatile RAM (NVRAM) or a flash memory.

Meanwhile, the IMS gateway 250 is a gateway that collects functions necessary for accessing the IMS-based IPTV service.

Particularly, it is possible to supply power to a control unit 325 that can be implemented in the form of a system on chip (SoC), a display unit 380 for displaying an image, and an audio output unit 335 for audio output . To this end, the power supply unit 340 may include a converter (not shown) for converting the AC power to the DC power. For example, when the display unit 380 is implemented as a liquid crystal panel having a plurality of backlight lamps, an inverter (not shown) capable of PWM (Pulse Width Modulation) operation for variable luminance or dimming driving and an inverter (not shown).

The remote control device 345 transmits the user input to the user input interface 320. [ To this end, the remote control device 345 may use Bluetooth, RF communication, infrared (IR) communication, UWB, ZigBee, or the like. The remote control device 345 can receive the video, audio, or data signal output from the user input interface 320 and display it on the remote control device 345 or output sound or vibration.

In addition, the digital TV according to the present invention may further include a configuration which is not shown or which is not reversed, as needed, among the configurations shown. On the other hand, the digital TV does not have a tuner and a demodulator but may receive and reproduce the content through the network interface unit or the external device interface unit.

3B, an example of the control unit includes a demultiplexer 350, an image processor, an OSD generator 366, a mixer 370, a frame rate converter (FRC) 380 ), And a formatter 390, as shown in FIG. The control unit may further include a voice processing unit and a data processing unit.

The demultiplexer 350 demultiplexes the input stream. For example, the demultiplexer 350 can demultiplex the received MPEG-2 TS video, audio, and data signals. Here, the stream signal input to the demultiplexer 350 may be a stream signal output from a tuner, a demodulator, or an external device interface.

The image processing unit performs image processing of the demultiplexed video signal. To this end, the image processing unit may include a video decoder 362 and a scaler 364. The video decoder 362 decodes the demultiplexed video signal, and the scaler 364 scales the decoded video signal so that the resolution of the decoded video signal can be output from the display unit. The video decoder 362 may support various standards. For example, the video decoder 362 performs the function of the MPEG-2 decoder when the video signal is encoded in the MPEG-2 standard, and the video decoder 362 encodes the video signal in the DMB (Digital Multimedia Broadcasting) It can perform the function of the H.264 decoder. On the other hand, the video signal decoded by the image processing unit is input to the mixer 370.

The OSD generating unit 366 generates OSD data according to a user input or by itself. For example, the OSD generating unit 366 generates data for displaying various data in the form of graphic or text on the screen of the display unit based on the control signal of the user input interface unit. The generated OSD data includes various data such as a user interface screen of a digital TV, various menu screens, a widget, an icon, and viewing rate information. The OSD generation unit 366 may generate data for displaying broadcast information based on a caption of a broadcast image or an EPG (Electronic Program Guide).

The mixer 370 mixes the OSD data generated by the OSD generating unit 366 and the image signal processed by the image processing unit and provides the mixed signal to the formatter 390. Since the decoded video signal and the OSD data are mixed, the OSD is overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 380 converts a frame rate of an input image. For example, the frame rate conversion unit 380 may convert the frame rate of the input 60 Hz image to have a frame rate of 120 Hz or 240 Hz, for example, in accordance with the output frequency of the display unit. As described above, there are various methods for converting the frame rate. For example, when the frame rate is changed from 60 Hz to 120 Hz, the frame rate conversion unit 380 may insert the same first frame between the first frame and the second frame, Three frames can be inserted. As another example, when converting the frame rate from 60 Hz to 240 Hz, the frame rate conversion unit 380 may insert and convert three or more identical frames or predicted frames between existing frames. On the other hand, when the frame conversion is not performed, the frame rate conversion unit 380 may be bypassed.

The formatter 390 changes the output of the input frame rate converter 380 to match the output format of the display unit. For example, the formatter 390 may output R, G, and B data signals, and the R, G, and B data signals may be output as low voltage differential signals (LVDS) or mini-LVDS . If the output of the input frame rate converter 380 is a 3D video signal, the formatter 390 may configure and output the 3D format according to the output format of the display unit to support the 3D service through the display unit.

On the other hand, the voice processing unit (not shown) in the control unit can perform the voice processing of the demultiplexed voice signal. Such a voice processing unit (not shown) may support processing various audio formats. For example, even when a voice signal is coded in a format such as MPEG-2, MPEG-4, AAC, HE-AAC, AC-3, or BSAC, a corresponding decoder can be provided. In addition, the voice processing unit (not shown) in the control unit can process the base, the treble, the volume control, and the like. A data processing unit (not shown) in the control unit can perform data processing of the demultiplexed data signal. For example, the data processing unit can decode the demultiplexed data signal even when it is coded. 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 on each channel.

Meanwhile, the above-described digital TV is an example according to the present invention, and each component can be integrated, added, or omitted according to specifications of a digital TV actually implemented. That is, if necessary, two or more components may be combined into one component, or one component may be divided into two or more components.

On the other hand, the log data may be collected on a time basis. The log data transmission may be periodic or non-periodic. The periodic transmission of the log data may be performed at a predetermined time or time unit. The period may be changed based on network traffic or log data on the digital TV 720 and the service server 730. [ On the other hand, the aperiodic transmission of the log data can be performed when a specific event occurs, for example, regardless of time, depending on an event. Meanwhile, the period and the non-periodic log data transmission may be appropriately combined.

The service server 730 analyzes the transmitted log data (S706). The analysis may be performed by only the log data of the corresponding device. Alternatively, the service server 730 can use log data of the corresponding digital TV 720 to analyze log data by referring to log data received from one or more other digital devices registered in advance. The service server 730 returns the log data analysis result to the corresponding digital TV 720 (S708). The return may be made according to various criteria upon request of the digital TV 720 or according to the judgment of the service server 730 itself.

The digital TV 720 stores the log data analysis result returned from the service server 730 in a memory (S710).

At least one of the steps S702 to S710 may be continuously performed and updated during a time point when the power of the digital TV 720 is turned off from the turn-on time.

For convenience, the digital TV 720 assumes that the power is turned on and that the first application is running on the screen. Meanwhile, the first application may correspond to all applications executable on the digital TV 720 such as a TV service application and a web application, but for convenience, the TV service application of a specific channel will be described as an example.

When a first control command is received from the mobile terminal 710 (S712), the digital TV 720 parses the received first control command. The digital TV 720 can identify the user who first transmitted the first control command in order to perform a function or operation based on the parsing result (S714). The user identification method may be based on the log data analysis result returned from the service server 730, or may be performed by various methods. However, if there is log-in information in the digital TV 720, for example, the user may be identified based on the identification information of the paired mobile terminal 710 based on the log-in information. In the present invention, unlike the above-described log-in information or identification information, the user identification relates to an approximate identification of an adult, a child, an elderly person, a man, a woman, etc., and if there is more accurate user identification information, Meanwhile, since the user identification process may be performed based on the log data analysis result returned from the service server 730, the user identification step may not necessarily be performed.

The digital TV 720 displays the first service log UI (S716). Here, the first service log UI may be, for example, the personalization icons shown in FIG. Accordingly, the first control command may be a personalization icon selection signal of any one of the personalization icons of FIG. Alternatively, if the first control command is a channel change request signal, the digital TV 720 may have the service log UI shown in FIG. 16 and below as the first service log UI. As described above, since the application provided through the screen of the digital TV 720 is a TV service application, the first service log UI can include a channel list. The first service log UI including the channel list is generated in advance based on at least one of the log data analysis result received from the service server 730 and the identified user information and stored in the memory, . That is, one or more channels provided through the first service log UI may be determined in advance based on, for example, a log data analysis result returned from the service server 730. At this time, VOD data whose channel number is not determined in advance, external input such as HDMI, web application such as web browser, game application, and the like can be arbitrarily allocated in advance in the digital TV 720. The randomly assigned channel number can be arbitrarily changed. This will be described in detail with reference to FIG.

When the second control command is received from the mobile terminal 710 (S718), the digital TV 720 parses the received second control command and displays a second service log UI corresponding to the parsed second control command (S720). When the third control command is received from the mobile terminal 710 (S722), the digital TV 720 parses the third control command, and in response to the parsed third control command, The display is displayed (S724). When the user selects a predetermined item from the displayed third service log UI, the digital TV 720 identifies the selected predetermined item. If the identified item is a specific application, for example, if the corresponding application data does not exist in the memory or the like, the digital TV 720 requests application data corresponding to the predetermined item identified by the service server 730 (S728). The service server 730 collects required application data according to a request from the digital TV 720 in operation S730 and returns the collected application data to the digital TV 720 in operation S732.

The digital TV 720 stores the application data returned from the service server 730 and can display it on the screen through an OSD or a UI when necessary. When the fifth control command is received from the user (S734), the digital TV 720 parses the fifth control command and performs an operation corresponding to the parsed fifth control command (S736).

In the above description, contents to display the first to fifth control commands and the corresponding first to third service log UIs are described. However, the present invention is not limited thereto. For example, some of the first to fifth control commands and some service log UIs among the first to third service log UIs may be omitted or merged as needed. Or vice versa.

On the other hand, the digital TV 720 collects and stores log data, and provides a service log UI according to the user's control command based on time information, user identification information, etc. based on the user's control command, It can automatically perform a specific function or operation.

FIG. 8 is a view for explaining a process of processing log data in the content discovery service system according to the present invention.

The service server 730 may communicate data with one or more digital TVs. 8, the first digital TV 810 and the second digital TV 820 are devices registered in advance in the service server 730 and are described as digital TVs having different device IDs (Identifiers) for the sake of convenience .

Referring to FIG. 8, the service server 730 includes a crawler / controller 832, a database 834, a log analysis engine 836, and the like.

The first digital TV 810 collects log data, transmits the collected log data to a predetermined signal, and transmits the log data to the crawler / controller 832.

The crawler / control unit 832 parses the log data of the received first digital TV 810 and transmits it to the database (DB) The crawler / control unit 832 may classify the parsed log data in advance and transmit the classified log data to the database (DB) 834. The classification may be performed based on each group or a combination thereof, such as a group unit, a device unit, an event unit, a time unit, or the like. In the above, the group may mean one or more digital devices grouped according to predetermined criteria. The grouping may be based on, for example, a device ID, a device type or a type, a device attribute, a network ID to which devices belong, and other setting items. For example, a plurality of digital TVs belonging to a home network may be a group. The device unit may mean an individual device or only a device of the same type or kind among a plurality of devices. For example, one or more digital TVs belonging to the home network may be one group unit or one device unit. On the other hand, a mobile terminal belonging to the home network may be a different device unit. The crawler / control unit 832 can control the classified log data to be separately stored in the database (DB) 834.

The log analysis engine 836 analyzes the log data stored in the database (DB) The log analysis engine 836 can analyze the log data units classified and stored according to the control of the crawler / The analyzed log data, that is, the log analysis data, is transferred directly to the crawler / controller 832 or stored in the database (DB) 834, and then returned to the corresponding digital TV.

The crawler / controller 832 may read the log analysis data stored in the database (DB) 834 and return to the first digital TV 810. Also, the return may be made at the request of the first digital TV 810.

In this regard, the second digital TV 820 shown in FIG. 8 carries out a data communication between the first digital TV 810 and the service server 730, It is omitted.

The log analysis engine 836 analyzes the log data received from the first digital TV 820 and / or the log analysis data of the first digital TV 820 at the time of analyzing the log data of the second digital TV 820 Can be referenced. The opposite is also true. Alternatively, when the first digital TV 810 and the second digital TV 820 are related to each other, for example, the log analysis engine 836 analyzes the first digital TV 810 and the second digital TV 820, (820) belong to the same group unit or the same device unit, it is possible to refer to each other's log data or the log analysis data analyzed in the log data analysis.

The log analysis engine 836 may use the original rating matrix R (user x item) as a model-based approach to transform U (user x hidden), which minimizes the least squared error WR (Alternating Least Squares with Wrighted-Lamda-Regularization) algorithm, which factorizes a feature with an M (item x hidden feature).

8 has been described as an individual digital TV having different device IDs, such as the first digital TV 810 and the second digital TV 820. However, the digital TV 810 and the digital TV (820) is a digital TV that processes a content discovery service using a digital TV (810) providing a screen at the time of log data collection and log analysis data received from the service server (730) Or a digital TV 820 providing a screen. In other words, it can be viewed as representing before and after the same digital TV or content discovery service.

FIG. 9 is a diagram illustrating an architecture of a service area related to a content discovery service according to an exemplary embodiment of the present invention, and FIG. 10 is a diagram illustrating a sequence diagram of FIG. 9. Referring to FIG.

Here, FIG. 9 may be supported by, for example, the WebOS TV platform.

The digital TV collects the log data and transmits it to the service server. Here, the log data may include data on channel preference such as a device ID, a MyChannel, a preferred recommendation list, and a weight.

The service server inquires the current broadcast channel list related to the log data from the database (DB) (mySQL-Channel) for the channel. In addition, the service server reads a real-time popular program list, a personalization list, and the like stored in the memory based on the presence or absence of the user's history.

The service server returns the personalized recommendation list for the device to the digital TV based on the read real-time popular program list, the personalization list, and the like.

In the content discovery service sequence diagram of FIG. 10, 'LIVE_MENU' related to a live menu and myRecommendedList related to a my recommended list are APIs for a content discovery service sequence according to the present invention, Application Program Interface). On the other hand, the TV, onNow Web, onNow WAS, IBS Web, and IBS WAS involved in the API call / return of FIG. 10 are respectively involved in call / return flow of the API, Hardware / software. Hereinafter, for ease of explanation, reference numerals are assigned to the respective components.

First, a live menu call sequence will be described as follows.

The TV 1010 calls a first request API for requesting a live menu according to a user's action. According to the first request API call, the onNow Web 1020 calls the second request API corresponding to the called first request API. According to the second request API call, the onNow WAS 1030 calls the third request API corresponding to the called second request API. At this time, the third request API may be an API for requesting a device-specific recommendation list corresponding to the live menu, not the live menu itself. In response to the third request API call, the IBS Web 1040 calls a fourth request API corresponding to the third request API. In response to the fourth request API call, the IBS WAS 1050 queries the database DB and reads data corresponding to the live menu or the device-specific recommendation list. The database (DB) may include a channel database (Channel DB) and an EPG database (EPG DB). The read data may include a real-time popular channel / program list, a personalized list, and the like.

Next, the response sequence corresponding to the API call according to the live menu request of the TV 1010 is the reverse order of the above-described call sequence. Therefore, detailed description of the response sequence will be omitted.

FIG. 11 is a diagram illustrating an architecture of a service area related to a content discovery service according to another embodiment of the present invention, and FIG. 12 is a diagram illustrating the sequence diagram of FIG.

FIG. 11 particularly shows a sequence diagram of a service in a service server according to a user's action.

When a user views a query or a predetermined program related to a digital TV with respect to a live menu, an application store, a wedge (VOD), etc., the IBS WAS receives a user ID, that is, a device ID, , And log data such as a user's click log (contentID).

The IBS WAS updates the ALS-WR model by adding preference information from the user's click log. The IBS WAS calculates a score after the ALS-WR model update and stores the score in a memory. The IBS WAS returns a response to the main WAS after storing the memory.

Referring to FIG. 12, a live menu click call sequence will be described as follows.

The TV 1210 calls the first API according to the click of the live menu according to the action of the user. According to the first API call, the onNow Web 1220 calls the second API corresponding to the called first API. According to the second API call, the onNow WAS 1230 stores the live menu click log data in the first database DB corresponding to the called second API, and calls the third request API. In response to the third request API call, the IBS WAS 1240 writes the personalization log data including the live menu click log data stored in the memory in the second database (DB).

Next, the response sequence corresponding to the API call according to the click of the live menu of the TV 1210 is the reverse order of the above-described call sequence. Therefore, detailed description of the response sequence will be omitted.

FIG. 13 is a diagram showing an architecture of a training area related to a content discovery service according to an embodiment of the present invention, and FIG. 14 is a diagram showing the sequence diagram of FIG.

FIG. 11 particularly shows a sequence diagram for training in a service server according to a user's action.

The recommended batch server queries and stores the database (DB) for a predetermined amount of data, for example, one match, of the user's click log data. Also, the posted distribution server stores the viewer log data of the user in the same manner as the database (DB).

Thereafter, the ordered distribution server performs computation on a model-by-model basis. Here, the model refers to a user, an item feature, or the like for deriving a user's preference item (program).

Through the above-described process, the user's preference program genre statistics by time zone are stored again in the database. At this time, it is preferable that the log data is merge based on the latest data.

The model is subjected to a full update through the above calculation, and the result is stored again in the database (DB). The above-described pool update process may be performed at predetermined intervals.

A DB call sequence for full update will be described with reference to FIG.

The IBS WAS 1410 queries the DB. The query may be performed in a polling manner that selects, i.e., checks whether a full update is ready.

The database DB transfers the DB query to the IBS Recommended 1420. The IBS Recommended 1420 transmits the received DB query to the Viewship log DB and the Click log data DB, (Insert / update).

Next, FIGS. 15 to 24 illustrate and describe a service scenario related to the content discovery service according to the present invention, and various UIs therefor.

15 is a diagram illustrating a personalization icon UI for a content discovery service according to an embodiment of the present invention.

Referring to FIG. 15, personalization icons may be called and displayed by input means of a digital TV, such as a remote controller, a mobile terminal, a camera sensor, a voice recognition sensor, and the like provided in the digital TV. On the other hand, in the case of the input means or the like, touch, key button selection, voice, gesture, eye-tracking or the like can be used.

In other words, FIG. 15 discloses a personalization icon for personalization service entry and identification, which may vary depending on the system. However, in the present specification, six men and women, male adolescents, adult male, elderly male, and elderly female were classified for convenience. Even if the user can not accurately identify the user through the camera sensor or the mobile terminal, the present invention identifies the corresponding user based on the log data based on the data communication with the service server, To perform a personalization service. Here, the personalization service includes a content discovery service for the identified user according to the present invention. According to the present invention, even if there are a plurality of users belonging to the same category, for example, adult women, the personalization service can be flexibly performed. Meanwhile, unlike the above, the personalization icon can be changed according to the setting or automatically such as a man / woman, an adult / a teen, a family / a non-family, or the like.

Referring to FIG. 15A, a digital TV provides a specific application execution screen as a full screen and a menu launcher based on a web OS platform in a predetermined area. In the context of the present invention, personalization icons 1520 may be provided on the upper right area of the screen. However, the present invention is not limited thereto. Meanwhile, the provided personalization icons 1520 may be performed according to the selection of the provided personalized menu item 1510 on the provided menu launcher as well as specific key buttons and the like.

In FIG. 15A, all six personalized icons are displayed for the sake of explanation, but if there is an identified user, only the corresponding personalized icons may be displayed. On the other hand, when the latter accesses a personalization icon corresponding to a specific user, it is possible to select another personalization icon, change the icon setting, and the like. Alternatively, when a particular personalization icon is selected, a personalization service, i.e., a content discovery service, may be provided, as described below.

15B, unlike FIG. 15A, personalization icons are provided at the center of the screen, and a digital TV screen may be provided according to a personalization icon selected from the provided personalization icons. At this time, depending on the setting, a menu shape, a menu size, a resolution, an audio setting, a screen configuration, and the like may be different according to each personalization icon.

As shown in FIGS. 15A and 15B, when a specific personalization icon is selected from among the provided personalization icons, the digital TV can immediately execute the application mapped to the selected personalization icon and provide a screen. On the other hand, if the selected personalization icon does not match the personalization icon on the previously analyzed log data, for example, it can be verified. For example, if the user on the log data analyzed in advance based on the current time is a juvenile man, if the juvenile icon is selected as an adult male, there may be an application requiring adult authentication or a juvenile-viewing disabled application among the recommended applications , And in such a case, it undergoes a verification procedure. Such verification can be accomplished in various ways such as password, pattern recognition, voice contrast, image matching obtained through a camera sensor, message transmission and authorization on a pre-registered parent mobile terminal.

On the other hand, not only the above-mentioned recommended application but also the message transmission time can be set differently for each personalization icon, for example, a viewable time (for example, one hour can be viewed), a specific channel access impossible, In addition, the settings for each personalized icon, such as resolution, brightness, and voice control range, can be set differently.

FIG. 16A is a scenario for providing a service UI when the content discovery service is invoked through FIG. 15 or another path. FIG.

Referring to FIG. 16A, a content discovery service UI 1610 is provided on the screen of a digital TV. The provided content discovery service UI 1610 includes a channel number, a channel name, a channel log, a playback bar, .

Referring to FIG. 16A, the digital TV provides a predetermined application execution screen through the entire screen, and a content discovery service UI 1610 may be provided in one area on the application execution screen.

In the above, the content discovery service UI 1610 may also be invoked by selecting a personalization icon provided in another area on the screen. Alternatively, the content discovery service UI 1610 may be provided according to an input control command. The control command may be, for example, a channel change request. For example, when the user wishes to view a channel other than the current channel, if the channel up / down button of the remote control is selected, the control command corresponding to the selection is transmitted to the digital TV. The digital TV parses the control command and provides a content discovery service UI 1610 including a recommended channel list as shown in FIG. 16A for channel switching of the identified user or channel surfing convenience.

On the other hand, the content discovery service UI 1610 may be provided with a list of related applications based on an application attribute currently being executed. As described above, if the application is a broadcast program of a specific channel, a list of recommended channels and programs for the identified user may also be provided with respect to the broadcast program. In other words, the provided content discovery service UI 1610 can recommend only the broadcast program if the application has the same attribute as the currently running application on the recommended list, for example, if the application is a broadcast program. However, the present invention is not limited thereto. For example, VOD and the like may be included.

The content discovery service UI 1610 provides six channels and programs, for example, in FIG. 16A. The content discovery service UI 1610 may further include additional channels and program lists in a form of wrap around or scrollable .

Also, channel switching (application switching) is directly performed to the channel and the broadcasting program corresponding to the selected item from the content discovery service UI 1610. Alternatively, the channel of the selected item may be previewed in the PIP or PBP format and may be finally selected by the user.

In addition, the channel and program of each item provided in the content discovery service UI 1610 may or may not be an application currently being provided. When an item of the former is selected, it immediately provides channel switching or PIP as described above. When the latter item is selected, sub-items (not shown) may be provided to enable selection of functions such as viewing reservation, instant recording, scheduled recording, and downloading.

16B is a diagram for explaining the channel number in relation to the present invention.

Generally, channels related to the TV service application provided by the digital TV are based on a method predetermined by a standard between the broadcasting station and the digital TV. That is, for each channel tuned by the digital TV, Is a channel, and the channel knows what broadcasting program it provides and services it. This is done, for example, based on the service data in the broadcast signal received over the channel. The EPG is also generated and provided based on the service data.

As such, channel data such as channel numbers are known in advance for applications related to terrestrial waves, cables, satellites, and IPTV services, and the user can provide services in response to channel up / down key button selection. The user also detects the channel selection according to his / her selection in advance. However, according to the content discovery service according to the present invention, a general web application other than the above-described TV service application, discovery is performed even if it is not necessarily a TV service application, and the result thereof is provided. With such a web application, for example, a VOD application can be illustrated. Referring to FIG. 16A, in the pooq application No. 333, the content called " three times three times again " is provided. Here, the channel number 333 is randomly allocated according to the present invention. That is, even if discovery is performed according to the content discovery service according to the present invention, the VOD application should be accessible to the user. However, since it is a different type of service in the related art, it has been required to perform a separate process, that is, to find and execute the corresponding application, to search for the desired content in the re-executed application, and to request execution. Of course, as shown in FIG. 16A, it is impossible to recognize or access the content through the content discovery service UI 1610 while using the TV service application.

The VOD application is assigned a channel number 333, which is a channel number arbitrarily assigned by the digital TV as described above. With the channel number structure of FIG. 16B, a channel number can be allocated for access convenience of a discovery application through a content discovery service other than the TV service application. This is to allow a user to conveniently access and discover desired applications simply by inputting channel up / down key buttons such as a remote controller or inputting channel numbers such as numbers.

The channel number structure of FIG. 16B may have a multi-channel number structure. However, the present invention is not limited to the multi-channel number structure. A digital channel number structure in the form of a physical number-logical number (for example, X-Y, 7-1, etc.) has recently been activated. In a similar manner, the present invention seeks to randomly assign a channel number to the VOD application based on a multi-channel number structure. In Fig. 16B, for example, a 3-channel number structure is illustrated. The first channel number 1622 refers to the VOD application server and the second channel number 1624 refers to the content of the series and the third channel number 1626 refers to the content of the second channel number 1624 It can mean content. For example, if the first channel number 1622 is X, it means the Pooq application server. If the second channel number 1624 is Y, it means the second season number 2 of the rural area. If the third channel number 1626 is Z, It can mean the third of season 2 of the three farm village side. In other words, the third episode of Season 3 of Season 3, provided by the Pooq application server, shows that the channel number is X-Y-Z. For example, in a numerical form, it can be expressed as 333-032-003, where 333 is the pooq application server, 032 is 0 for free content, 3 is for rural, 2 is for season 2, and 003 can mean three. By arbitrarily allocating the channel number in this way, the user can predict the content such as other series based on the current content in advance and select the channel only with the channel number, thereby maximizing user convenience. It is preferable that the randomly allocated channel number is provided so as not to overlap with a pre-allocated TV service application. However, even if they are duplicated, the same channel number should not be assigned completely.

FIG. 17 shows a channel content discovery service UI configured to easily recognize information about a previous channel and a next channel before a channel up / down for user convenience, for example. This is for the purpose of enhancing the selection convenience when, for example, the user is aware of the channel number or if he / she mainly selects the channel up / down button. Meanwhile, the previous channel / next channel UI may be changed to, for example, a favorite channel list UI.

Referring to FIG. 17A, a previous channel and a next channel UI are provided in the same form as a channel browser UI for a current channel.

On the other hand, referring to FIG. 17B, unlike the channel browser UI for the current channel, the previous channel and the next channel UI provide preview image data for the program currently being broadcasted on the channel. For example, if the user tries to switch from the current channel to the next channel and is presently advertising on the next channel, or before the desired program has yet been provided, it may wait for channel switching or access another channel.

For example, if a channel browser for a current channel is selected as well as a channel browser for another channel, the user can directly switch to the corresponding channel in FIGS. 17A and 17B. Alternatively, if a channel browser for the other channel is selected, it can be maintained in the case of channel switching to another channel of the user. The channel browser selection for the other channel is accepted as a viewing reservation of the user so as to save the viewing reservation of the user.

FIG. 18 shows a content discovery service according to the present invention in combination with the above-described FIG. 16A and FIG. 17A.

At this time, the content discovery service UI 1810 may or may not include the channel (s) being provided to the channel browser UI being provided on the screen.

On the other hand, FIG. 19 is an implementation of the content discovery service UI 1910 in a manner different from FIG. For example, the content discovery service UI 1910 of FIG. 19 implements channel lists in the content discovery service UI 1810 of FIG. 18 in the form of a menu launcher of FIG.

The digital TV displays a function icon 1942 and a corresponding channel item 1930 for performing functions such as viewing reservation, recording reservation, channel switching, and the like of the corresponding channel in the vicinity of the channel item 1930 selected by the cursor 1920 in FIG. A deletion icon 1944 for deleting the content from the content discovery service UI 1910, and the like.

Meanwhile, the content discovery service UI 1910 arranges channel items from left to right according to various criteria such as channel order, preference order, and the like, according to predetermined rules. Referring to FIG. 19, a total of five channel items are provided, as described above, which may be wraparound or scrolling, and scroll icons 1952 and 1954 for that may be further provided. Scrolling for searching for the channel items may be performed in various ways in addition to the icons 1952 and 1954. [

Next, FIG. 20 shows an example of a scenario in which a content discovery service is performed in a digital TV when a predetermined channel item 1930 is selected in FIG. 19, for example.

Referring to FIG. 20, the digital TV reads information on the selected channel item. According to the read result, the subchannel items 2020, 2032, and 2034 can be provided directly in the content discovery service UI.

For example, assume that the selected channel item is the VOD content of the Pooq application. The channel item 1930 selected by the cursor 2010 is changed to the channel item 2020 shown in FIG. 20, and the channel item 2020 is selected as the channel item 2020 of FIG. can do. At this time, around the channel item 2020, a series of midnight season 7 series 2032 and 2034 that can be provided or provided by the pooq application may be provided together.

In addition, the channel item 2020 and / or the subchannel items 2032 and 3024 in FIG. 20 may be provided so that function icons can be selected around the channel item 2020 and / or the subchannel items 2032 and 3024 as shown in FIG.

When the function icons are selected, a predetermined function may be provided or an OSD / UI mapped to the function icons may be provided. The OSD / UI can provide data on various functions and items such as viewing reservation, channel switching, recording reservation, instant recording, resolution change, download / storage, volume setting, time machine function setting, have.

21 is provided with the content discovery service UI 2110 as shown in Fig. 16A, but unlike Fig. 16A, a function box or a function icon (hereinafter, function icon) 2120 is provided corresponding to each channel item.

The function icon 2120 can be set according to a user action in a predetermined form such as selection, deletion, and the like. For example, if the function icon item is displayed as 'x' according to the user action, the corresponding channel item may be deleted from the content discovery service UI 2110. Also, when the function icon item is displayed as 'v' according to the user action, the corresponding channel item may be set to perform a predetermined function.
