2 is a block diagram illustrating a digital device according to an exemplary embodiment of the present invention.

The digital device described herein corresponds to the client 100 of FIG. 1 described above.

The digital device 200 includes a network interface 201, a TCP / IP manager 202, a service delivery manager 203, an SI decoder 204, A demultiplexer (demux 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 manager 214, and the like.

The network interface unit 201 receives the IP packet (s) (IP packet (s)) or the IP datagram (s) ) Is transmitted / received. For example, the network interface unit 201 can receive services, applications, content, and the like from the service provider 20 of FIG. 1 through a network.

The TCP / IP manager 202 determines whether the IP packets received by the digital device 200 and the IP packets transmitted by the digital device 200 are packet delivery (i.e., packet delivery) between a source and a 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 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 application manager may include, for example, the UI manager 214 and the service manager 213 and may perform the functions of the controller of the digital device 200. [ In other words, the application manager can manage the overall state of the digital device 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 transmits the key input signal to the service manager 213 upon receipt of a key input from the user regarding channel selection.

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.

The service manager 213 also generates a channel map and controls the selection of a channel using the generated channel map according to the 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 VOD (Video on Demand) , RTSP is used to select and control services. The RTSP protocol may provide a trick mode for real-time streaming. Also, 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.

For example, the frame rate conversion unit 555 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 converting the frame rate from 60 Hz to 120 Hz, the frame rate conversion unit 555 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 555 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 555 may be bypassed.

The structure of the software for digital devices is based on a single process and a closed product based on multi-threading with conventional problem solving and market-dependent monolithic structure, And has been pursuing new platform-based development since then, has pursued cost innovation through chip-set replacement, UI application and external application development efficiency, and developed layering and componentization Layer structure and an add-on structure for add-ons, single-source products, and open applications. More recently, the software architecture provides a modular architecture for functional units, a Web Open API (Application Programming Interface) for echo-systems, and a game engine And a native open API (Native Open API), and thus, a multi-process structure based on a service structure is being created.

7 is a diagram illustrating a Web OS architecture according to an embodiment of the present invention.

Referring to FIG. 7, the architecture of the Web OS platform will be described as follows.

The platform can be largely divided into a kernel, a system library based Web OS core platform, an application, and a service.

The architecture of the Web OS platform is layered structure, with the OS at the lowest layer, the system library (s) at the next layer, and the applications at the top.

First, the lowest layer includes a Linux kernel as an OS layer, and can include Linux as an OS of the digital device.

The OS layer is provided with a BOS (Board Support Package) / HAL (Hardware Abstraction Layer) layer, a Web OS core modules layer, a service layer, a Luna-Service layer Bus layer, Native Developer ◎ Kit / QT layer, and Application layer in the top layer.

Meanwhile, some layers of the above-described web OS layer structure may be omitted, and a plurality of layers may be one layer, or one layer may be a plurality of layer structures.

The web OS core module layer is composed of a Luna Surface Manager (LSM) for managing surface windows and the like, a System & Application Manager (SAM) for managing the execution and execution status of applications, and a WebKit And a WAM (Web Application Manager) for managing web applications and the like.

The LSM manages an application window displayed on the screen. The LSM manages display hardware (Display HW) and provides a buffer for rendering contents necessary for applications. The LSM composes the results of rendering by a plurality of applications, Can be output.

The SAM manages various conditional execution policies of the system and the application.

WAM, on the other hand, is based on the Enyo Framework, which can be regarded as a basic application for web applications.

The use of an application's service is done via a luna-service bus, a new service can be registered on the bus, and an application can find and use the service it needs.

The service layer may include various service level services such as TV service and Web OS service. Meanwhile, the web OS service may include a media server, a Node.JS, and the like. In particular, the Node.JS service supports, for example, javascript.

Web OS services can communicate over a bus to a Linux process that implements function logic. It can be divided into four parts. It is developed from TV process and existing TV to Web OS, services that are differentiated by manufacturer, service which is manufacturer's common service and JavaScript, and is used through Node.js Node.js service.

The application layer may include all applications that can be supported in a digital device, such as a TV application, a showcase application, a native application, a web application, and the like.

An application on the Web OS can be divided into a Web application, a PDK (Palm Development Kit) application, a QT (Qt Meta Language or Qt Modeling Language) application and the like depending on an implementation method.

The web application is based on a WebKit engine and is executed on a WAM runtime. These web applications can be based on the ENI framework, or they can be developed and run on a common HTML5, CSS (Cascading Style Sheets), or JavaScript based.

The PDK application includes a native application developed in C / C ++ based on a PDK provided for third-party or external developers. The PDK refers to a development library and a tool set provided for a third party such as a game to develop a native application (C / C ++). For example, PDK applications can be used to develop applications where performance is critical.

The QML application is a Qt-based native application and includes a basic application provided with a web OS platform such as a card view, a home dashboard, a virtual keyboard, and the like. Here, QML is a mark-up language in the form of a script instead of C ++.

In the meantime, the native application is an application that is developed and compiled in C / C ++ and executed in a binary form. The native application has a high speed of execution.

FIG. 8 is a diagram illustrating an architecture of a Web OS device according to an exemplary embodiment of the present invention. Referring to FIG.

8 is a block diagram based on the runtime of the Web OS device, which can be understood with reference to the layered structure of FIG.

The following description will be made with reference to FIGS. 7 and 8. FIG.

Referring to FIG. 8, services and applications and WebOS core modules are included on the system OS (Linux) and system libraries, and communication between them can be done via the Luna-Service bus.

E-mail, contact, calendar, etc. Node.js services based on HTML5, CSS, java script, logging, backup, file notify notify, database (DB), activity manager, system policy, audio daemon (AudioD), update, media server, TV services such as Electronic Program Guide (PVD), Personal Video Recorder (PVR), data broadcasting, voice recognition, Now on, Notification, search, , CP services such as Auto Content Recognition (ACR), Contents List Browser (CBOX), wfdd, DMR, Remote Application, download, Sony Philips Digital Interface Format (SDPIF), PDK applications, , QML applications, etc. And the enyo framework based on the TV UI-related applications and web applications, Luna - made the process via the Web OS core modules, such as the aforementioned SAM, WAM, LSM via the service bus. Meanwhile, in the above, TV applications and web applications may not necessarily be UI-based or UI-related.

CBOX can manage the list and metadata of external device contents such as USB, DLNA, cloud etc. connected to TV. Meanwhile, the CBOX can output a content listing of various content containers such as a USB, a DMS, a DVR, a cloud, etc. to an integrated view. In addition, CBOX can display various types of content listings such as pictures, music, video, and manage the metadata. In addition, the CBOX can output the contents of the attached storage in real-time. For example, when a storage device such as a USB is plugged in, the CBOX must be able to immediately output the content list of the storage device. At this time, a standardized method for processing the content listing may be defined. In addition, CBOX can accommodate various connection protocols.

The SAM is intended to improve module complexity and scalability. For example, the existing system manager processes various functions such as system UI, window management, web application runtime, and UX constraint processing in one process to separate the main functions to solve the large implementation complexity, Clarify the implementation interface by clarifying the interface.

LSM supports independent development and integration of system UX implementations such as card view, launcher, etc., and supports easy modification of product requirements. LSM can make multi-tasking possible by utilizing hardware resources (HW resources) when synthesizing a plurality of application screens such as an application in-app, A window management mechanism can be provided.

LSM supports implementation of system UI based on QML and improves its development productivity. Based on MVC, QML UX can easily construct views for layouts and UI components, and can easily develop code for handling user input. On the other hand, the interface between the QML and the Web OS component is via the QML extension plug-in, and the graphic operation of the application can be based on the wayland protocol, luna-service call, etc. have.

LSM is an abbreviation of Luna Surface Manager, as described above, which functions as an Application Window Compositor.

LSM synthesizes independently generated applications, UI components, etc. on the screen and outputs them. In this regard, when components such as recents applications, showcase applications, launcher applications, etc. render their own contents, the LSM defines the output area, interworking method, etc. as a compositor. In other words, the compositor LSM handles graphics synthesis, focus management, input events, and so on. At this time, the LSM receives events, focus, etc. from the input manager. These input managers can include HIDs such as remote controllers, mouse & keyboards, joysticks, game pads, application remotes, and pen touches.

As such, LSM supports multiple window models, which can be performed simultaneously in all applications due to the nature of the system UI. In this regard, it is also possible to provide various functions such as launcher, resent, setting, notification, system keyboard, volume UI, search, finger gesture, Voice Recognition (STT (Sound to Text), TTS LSM can support a pattern gesture (camera, mobile radio control unit (MRCU), live menu, ACR (Auto Content Recognition), etc.) .

9 is a diagram illustrating a graphic composition flow in a web OS device according to an embodiment of the present invention.

9, the graphic composition processing includes a web application manager 910 responsible for the UI process, a webkit 920 responsible for the web process, an LSM 930, and a graphic manager (GM) Lt; RTI ID = 0.0 > 940 < / RTI >

When the web application-based graphic data (or application) is generated as a UI process in the web application manager 910, the generated graphic data is transferred to the LSM 930 if the generated graphic data is not a full-screen application. On the other hand, the web application manager 910 receives an application generated in the web kit 920 for sharing a GPU (Graphic Processing Unit) memory for graphic management between the UI process and the web process, If it is not an application, it transfers it to the LSM 930. In the case of the full-screen application, the LSM 930 may be bypassed and directly transmitted to the graphic manager 940.

The LSM 930 transmits the received UI application to the wayland compositor via the weir surface, and the weir composer appropriately processes the received UI application and transmits it to the graphic manager. The graphic data transmitted from the LSM 930 is transmitted to the graphic manager composer via the LSM GM surface of the graphic manager 940, for example.

On the other hand, the full-screen application is passed directly to the graphics manager 940 without going through the LSM 930, as described above, and this application is processed in the graphics manager compositor via the WAM GM surface.

The graphical manager processes all the graphic data in the web OS device, including the data through the LSM GM surface described above, the data through the WAM GM surface, as well as the GM surface such as data broadcasting application, caption application, And processes the received graphic data appropriately on the screen. Here, the functions of the GM compositor are the same or similar to those of the compositor described above.

FIG. 10 is a view for explaining a media server according to an embodiment of the present invention, FIG. 11 is a view for explaining a configuration block diagram of a media server according to an embodiment of the present invention, and FIG. 12 Is a diagram illustrating a relationship between a media server and a TV service according to an embodiment of the present invention.

The media server supports the execution of various multimedia in the digital device and manages the necessary resources. The media server can efficiently use hardware resources required for media play. For example, the media server requires an audio / video hardware resource for multimedia execution and can efficiently utilize the resource usage status by managing it. In general, a fixed device having a larger screen than a mobile device needs more hardware resources to execute multimedia, and a large amount of data must be encoded / decoded and transmitted at a high speed. On the other hand, the media server is a task that performs broadcasting, recording and tuning tasks in addition to streaming and file-based playback, recording simultaneously with viewing, and simultaneously displaying the sender and recipient screens in a video call And so on. However, the media server is limited in terms of hardware resources such as an encoder, a decoder, a tuner, and a display engine, and thus it is difficult to execute a plurality of tasks at the same time. For example, And processes it.

The media server may be robust in system stability because, for example, a pipeline in which an error occurs during media playback can be removed and restarted on a per-pipeline basis, Even if it does not affect other media play. Such a pipeline is a chain that links each unit function such as decoding, analysis, and output when a media reproduction request is made, and the necessary unit functions may be changed according to a media type and the like.

The media server may have extensibility, for example, adding a new type of pipeline without affecting existing implementations. As an example, the media server may accommodate a camera pipeline, a video conference (Skype) pipeline, a third-party pipeline, and the like.

The media server can process general media playback and TV task execution as separate services because the interface of the TV service is different from the case of media playback. The media server supports operations such as setchannel, channelup, channeldown, channeltuning, and recordstart in connection with TV services and supports operations such as play, pause, and stop in connection with general media playback, Operations can be supported and processed as separate services.

The media server can control or integrally manage the resource management function. The allocation and recall of hardware resources in the device are performed integrally in the media server. In particular, the TV service process transfers the running task and the resource allocation status to the media server. The media server obtains resources and executes the pipeline each time each media is executed, and permits execution by a priority (e.g., policy) of the media execution request, based on the resource status occupied by each pipeline, and And performs resource recall of other pipelines. Here, the predefined execution priority and necessary resource information for the specific request are managed by the policy manager, and the resource manager can communicate with the policy manager to process the resource allocation, the number of times, and the like.

The media server may have an identifier (ID) for all playback related operations. For example, the media server may issue a command to indicate a particular pipeline based on the identifier. The media server may separate the two into pipelines for playback of more than one media.

The media server may be responsible for playback of the HTML 5 standard media.

In addition, the media server may follow the TV restructuring scope of the TV pipeline as a separate service process. The media server can be designed regardless of the TV restructuring scope. If the TV is not a separate service process, it may be necessary to re-execute the entire TV when there is a problem with a specific task.

The media server is also referred to as uMS, i.e., a micro media server. Here, the media player is a media client, which is a media client, for example, a web page for an HTML5 video tag, a camera, a TV, a Skype, a second screen, It can mean a kit (Webkit).

In the media server, management of micro resources such as a resource manager, a policy manager, and the like is a core function. In this regard, the media server also controls the playback control role for the web standard media content. In this regard, the media server may also manage pipeline controller resources.

Such a media server supports, for example, extensibility, reliability, efficient resource usage, and the like.

In other words, the uMS or media server may be a web OS device, such as a resource, such as a cloud game, a MVPD (pay service), a camera preview, a second screen, a Skype, And manage and control the use of resources for proper processing in an overall manner so as to enable efficient use. On the other hand, each resource uses, for example, a pipeline in its use, and the media server can manage and control the generation, deletion, and use of a pipeline for resource management as a whole.

Here, the pipeline refers to, for example, when a media associated with a task starts a series of operations, such as parsing of a request, a decoding stream, and a video output, . For example, with respect to a TV service or an application, watching, recording, channel tuning, and the like are each individually handled under the control of resource utilization through a pipeline generated according to the request .

The processing structure and the like of the media server will be described in more detail with reference to FIG.

10, an application or service is connected to a media server 1020 via a luna-to-service bus 1010, and the media server 1020 is connected to pipelines generated again via the luna- Connected and managed.

The application or service can have various clients depending on its characteristics and can exchange data with the media server 1020 or the pipeline through it.

The client includes, for example, a uMedia client (web kit) and a RM (resource manager) client (C / C ++) for connection with the media server 1020.

The application including the uMedia client is connected to the media server 1020, as described above. More specifically, the uMedia client corresponds to, for example, a video object to be described later, and the client uses the media server 1020 for the operation of video by a request or the like.

Here, the video operation relates to the video state, and the loading, unloading, play, playback, or reproduce, pause, stop, Data may be included. Each operation or state of such video can be processed through individual pipeline generation. Accordingly, the uMedia client sends the state data associated with the video operation to the pipeline manager 1022 in the media server.

The pipeline manager 1022 obtains information on resources of the current device through data communication with the resource manager 1024 and requests resource allocation corresponding to the state data of the uMedia client. At this time, the pipeline manager 1022 or the resource manager 1024 controls resource allocation through the data communication with the policy manager 1026 when necessary in connection with the resource allocation or the like. For example, when the resource manager 1024 requests or does not have resources to allocate according to a request of the pipeline manager 1022, appropriate resource allocation or the like may be performed according to the priority comparison of the policy manager 1026 or the like .

On the other hand, the pipeline manager 1022 requests the media pipeline controller 1028 to generate a pipeline for an operation according to the request of the uMedia client with respect to resources allocated according to the resource allocation of the resource manager 1024 .

The media pipeline controller 1028 generates necessary pipelines under the control of the pipeline manager 1022. [ The generated pipeline can generate pipelines related to playback, pause, suspension, etc., as well as media pipelines and camera pipelines, as shown. The pipeline may include pipelines for HTML5, Web CP, smartshare playback, thumbnail extraction, NDK, Cinema, MHEG (Multimedia and Hypermedia Information Coding Experts Group), and the like.

In addition, the pipeline may include, for example, a service-based pipeline (its own pipeline) and a URI-based pipeline (media pipeline).

Referring to FIG. 10, an application or service including an RM client may not be directly connected to the media server 1020. This is because the application or service may directly process the media. In other words, if the application or service directly processes the media, it may not pass through the media server. However, at this time, uMS connectors need to manage resources for pipeline creation and use. Meanwhile, when receiving a resource management request for direct media processing of the application or service, the uMS connector communicates with the media server 1020 including the resource manager 1024. To this end, the media server 1020 also needs to have an uMS connector.

Accordingly, the application or service can respond to the request of the RM client by receiving the resource management of the resource manager 1024 through the uMS connector. These RM clients can handle services such as native CP, TV service, second screen, Flash player, YouTube Medai Source Extensions (MSE), cloud gaming, Skype. In this case, as described above, the resource manager 1024 can appropriately manage resources through data communication with the policy manager 1026 when necessary for resource management.

On the other hand, the URI-based pipeline is performed through the media server 1020 instead of processing the media directly as in the RM client described above. Such URI-based pipelines may include a player factory, a G streamer, a streaming plug-in, a DRM (Digital Rights Management) plug-in pipeline, and the like.

On the other hand, the interface method between application and media services may be as follows.

It is a way to interface with a service in a web application. This is a way of using Luna Call using the Palm Service Bridge (PSB), or using Cordova, which extends the display to video tags. In addition, there may be a method using the HTML5 standard for video tags or media elements.

And, it is a method of interfacing with PDK using service.

Alternatively, it is a method of using the service in the existing CP. It can be used to extend existing platform plug-ins based on Luna for backward compatibility.

Finally, it is a way to interface in the case of non-web OS. In this case, you can interface directly by calling the Luna bus.

Seamless change is handled by a separate module (eg TVWIN), which is the process for displaying and streamlining the TV on the screen without Web OS, before or during WebOS boot . This is because the boot time of WebOS is delayed, so it is used to provide the basic function of the TV service first for quick response to the user's power on request. In addition, the module is part of the TV service process and supports quick boot and null change, which provides basic TV functions, and factory mode. In addition, the module may also switch from the Non-Web OS mode to the Web OS mode.

Referring to FIG. 11, a processing structure of a media server is shown.

11, the solid line box represents the process processing configuration, and the dashed box represents the internal processing module during the process. In addition, the solid line arrows represent inter-process calls, that is, Luna service calls, and the dotted arrows may represent notifications or data flows such as register / notify.

A service or a web application or a PDK application (hereinafter referred to as an application) is connected to various service processing components via a luna-service bus, through which an application is operated or controlled.

The data processing path depends on the type of application. For example, when the application is image data related to the camera sensor, the image data is transmitted to the camera processing unit 1130 and processed. At this time, the camera processing unit 1130 processes image data of a received application including a gesture, a face detection module, and the like. Here, the camera processing unit 1130 can generate a pipeline through the media server processing unit 1110 and process the corresponding data if the user desires to use the pipeline or the like.

Alternatively, when the application includes audio data, the audio processing unit (AudioD) 1140 and the audio module (PulseAudio) 1150 can process the audio. For example, the audio processing unit 1140 processes the audio data received from the application and transmits the audio data to the audio module 1150. At this time, the audio processing unit 1140 may include an audio policy manager to determine processing of the audio data. The processed audio data is processed in the audio module 1160. Meanwhile, the application can notify the audio data processing related data to the audio module 1160, which can also perform the notification to the audio module 1160 in the associated pipeline. The audio module 1150 includes an Advanced Linux Sound Architecture (ALSA).

Alternatively, when the application includes or processes (includes) DRM-attached content, the DRM service processing unit 1170 transmits the content data to the DRM service processing unit 1160, and the DRM service processing unit 1170 generates a DRM instance And processes the DRM-enabled content data. Meanwhile, the DRM service processing unit 1160 may process the DRM pipeline in the media pipeline through the Luna-Service bus to process the DRM-applied content data.

Hereinafter, processing in the case where the application is media data or TV service data (e.g., broadcast data) will be described.

FIG. 12 shows only the media server processing unit and the TV service processing unit in FIG. 11 described above in more detail.

Therefore, the following description will be made with reference to FIGS. 11 and 12. FIG.

First, when the application includes TV service data, it is processed in the TV service processing unit 1120/1220.

The TV service processing unit 1120 includes at least one of a DVR / channel manager, a broadcasting module, a TV pipeline manager, a TV resource manager, a data broadcasting module, an audio setting module, and a path manager. 12, the TV service processing unit 1220 includes a TV broadcast handler, a TV broadcast interface, a service processing unit, a TV middleware (TV MW (middleware)), a path manager, a BSP For example, NetCast). Here, the service processing unit may be a module including, for example, a TV pipeline manager, a TV resource manager, a TV policy manager, a USM connector, and the like.

In this specification, the TV service processing unit may have a configuration as shown in Fig. 11 or 12, or may be implemented by a combination of both, in which some configurations are omitted or some configurations not shown may be added.

The TV service processing unit 1120/1220 transmits the data to the DVR / channel manager in the case of DVR (Digital Video Recorder) or channel related data based on the attribute or type of the TV service data received from the application, To generate and process the TV pipeline. On the other hand, when the attribute or type of the TV service data is broadcast content data, the TV service processing unit 1120 generates and processes the TV pipeline through the TV pipeline manager for processing the corresponding data via the broadcasting module.

Alternatively, a json (JavaScript standard object notation) file or a file created in c is processed by a TV broadcast handler and transmitted to a TV pipeline manager through a TV broadcast interface to generate and process a TV pipeline. In this case, the TV broadcast interface unit may transmit the data or the file that has passed through the TV broadcast handler to the TV pipeline manager based on the TV service policy and refer to it when creating the pipeline.

On the other hand, the TV pipeline manager can be controlled by the TV resource manager in generating one or more pipelines according to a TV pipeline creation request from a processing module in a TV service, a manager, or the like. Meanwhile, the TV resource manager can be controlled by the TV policy manager to request the status and allocation of resources allocated for the TV service according to the TV pipeline creation request of the TV pipeline manager, and the media server processing unit 1110 / 1210) and uMS connectors. The resource manager in the media server processing unit 1110/1210 transmits the status of the current TV service, the allocation permission, etc. according to the request of the TV resource manager. For example, if a resource manager in the media server processing unit 1110/1210 confirms that all the resources for the TV service have already been allocated, the TV resource manager can notify that all the resources are currently allocated. At this time, the resource manager in the media server processing unit, together with the notify, removes a predetermined TV pipeline according to a priority or a predetermined criterion among the TV pipelines preliminarily allocated for the TV service, And may request or assign generation. Alternatively, the TV resource manager can appropriately remove, add, or control the TV pipeline in the TV resource manager according to the status report of the resource manager in the media server processing unit 1110/1210.

Meanwhile, the BSP supports, for example, backward compatibility with existing digital devices.

The TV pipelines thus generated can be appropriately operated according to the control of the path manager in the process. The path manager can determine and control the processing path or process of the pipelines by considering not only the TV pipeline but also the operation of the pipeline generated by the media server processing unit 1110/1210.

Next, when the application includes media data, rather than TV service data, it is processed by the media server processing unit 1110/1210. Here, the media server processing units 1110 and 1210 include a resource manager, a policy manager, a media pipeline manager, a media pipeline controller, and the like. On the other hand, the pipeline generated according to the control of the media pipeline manager and the media pipeline controller can be variously generated such as a camera preview pipeline, a cloud game pipeline, and a media pipeline. On the other hand, the media pipeline may include a streaming protocol, an auto / static gstreamer, and a DRM, which can be determined according to the control of the path manager. The specific processing in the media server processing units 1110 and / or 1210 cites the description of FIG. 10 described above, and will not be repeated here.

In this specification, the resource manager in the media server processing unit 1110/1210 can perform resource management with, for example, a counter base.

13 is a diagram illustrating a control method of a remote controller for controlling any one of the video display devices according to the embodiments of the present invention.

13A illustrates that the pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180. As shown in FIG.

The user can move or rotate the remote control device 200 up and down, left and right (Fig. 13 (b)), and back and forth (Fig. 13 (c)). The pointer 205 displayed on the display unit 180 of the video display device corresponds to the motion of the remote control device 200. [ In this remote control device 200, as shown in the figure, since the pointer 205 is moved according to the movement in the 3D space, it can be called a space remote controller.

13B illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display unit 180 of the video display device also shifts to the left corresponding thereto.

Information on the motion of the remote control device 200 sensed through the sensor of the remote control device 200 is transmitted to the image display device. The video display device can calculate the coordinates of the pointer 205 from the information about the motion of the remote control device 200. [ The video display device can display the pointer 205 so as to correspond to the calculated coordinates.

13C illustrates a case where the user moves the remote control device 200 away from the display unit 180 while the specific button in the remote control device 200 is pressed. Thereby, the selected area in the display unit 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control apparatus 200 close to the display unit 180, the selection area within the display unit 180 corresponding to the pointer 205 may be zoomed out and displayed. On the other hand, when the remote control device 200 moves away from the display unit 180, the selected area is zoomed out, and when the remote control device 200 approaches the display unit 180, the selected area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control device 200 moves away from or approaches the display unit 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

The pointer in the present specification means an object displayed on the display unit 180 in correspondence with the operation of the remote control device 200. [ Therefore, various shapes of objects other than the arrow shapes shown in the drawings are possible with the pointer 205. [ For example, it can be a concept that includes points, cursors, prompts, thick outlines, and so on. The pointer 205 may be displayed corresponding to a point on a horizontal axis or a vertical axis on the display unit 180 or may be displayed corresponding to a plurality of points such as a line or a surface Do.

14 is an internal block diagram of a remote controller for controlling any one of the video display devices according to the embodiments of the present invention.

14, the remote control device 200 includes a wireless communication unit 225, a user input unit 235, a sensor unit 240, an output unit 250, a power supply unit 260, a storage unit 270, , And a control unit 280. [

The wireless communication unit 225 transmits / receives a signal to / from any one of the video display devices according to the above-described embodiments of the present invention. Of the video display devices according to the embodiments of the present invention, one video display device 100 will be described as an example.

In this embodiment, the remote control device 200 may include an RF module 221 that can transmit and receive signals to and from the image display device 100 according to the RF communication standard.

In this case,

17, the controller 1530 receives a command for selecting a specific portion of the first area from the external remote controller 1740 through the communication module 1520 using the pointer 1734 And displays a specific area 1732 to be enlarged corresponding to the received command in advance. Therefore, there is an advantage in that a user can confirm in advance which region will be enlarged.

FIG. 18 is a diagram illustrating a pointer shape being changed when a specific area enlarging mode according to an embodiment of the present invention is activated.

18, when a command is received from the external remote controller 1830 to activate the specific area mode 1840, the controller 1530 changes the pointer shape from the original shape (first graphic image) to another shape Graphic image).

For example, if the magnification ratio is increased in the specific area enlargement mode, the controller 1530 changes the pointer shape from the original shape 1810 to the + shape 1820.

When the enlargement ratio is reduced in the specific area enlargement mode, the controller 1530 changes the shape of the pointer to -shaped.

Therefore, according to the embodiment of the present invention, when the specific area enlargement mode is activated, the pointer changes to a magnifying glass shape and the pointer shape changes according to the increase and decrease of the enlargement ratio, It is intuitively known whether or not the increase rate is increased and the user convenience is improved.

FIG. 19 is a diagram illustrating control of a screen when a specific area enlargement mode is activated according to an embodiment of the present invention. Of course, it is also possible to simply name it "enlargement mode" instead of "specific area enlargement mode" for convenience.

First, a display device according to an embodiment of the present invention displays content on a main screen 1910, and enters an enlargement mode according to an enlargement input request received from a remote controller.

Displays a window 1920 containing the content displayed on the main screen 1910 and displays an indicator 1930 in the displayed window 1920 for selecting a specific area of the displayed content.

To enlarge a selected specific area of the displayed content and to magnify and display a selected specific area of the displayed content on the main screen 1910. [ The content corresponds to, for example, a moving picture.

Of course, for convenience of explanation, the main screen 1910 may be referred to as a first area and the window 1920 may be referred to as a second area. There is no limitation on the shape or size of the window 1920.

More specifically, for example, when video data included in a broadcast signal is output from the main screen 1910 and an input signal is received from the remote controller 1940 for a predetermined time or longer (for example, an OK button) The video data is also displayed on the display unit 1920. When the specific area enlargement mode is executed for the first time, the same video data is output to the main screen 1910 and the window 1920. The video data displayed on the main screen 1910 and the video data displayed on the window 1920 are the same but only different in size.

Further, an indicator 1930 is displayed in the window 1920, and the indicator 1930 is used to select a specific area to be enlarged by the user. For example, as shown in FIG. 19, the indicator 1930 may be implemented as a graphic image of a guide box that guides a specific area to be enlarged or already enlarged, but it is also possible to adopt a graphic image of another shape All of which fall within the scope of the present invention.

The window 1920 may be referred to as a total window or the indicator 1930 may be referred to as a local window. Then, the area specified by the indicator 1930 is enlarged and outputted to the main screen 1910. When the user first enters the specific area enlargement mode, the original (original) video data is output to the main screen 1910, and the original (original) video data is displayed on the main screen 1910 using the window 1920 and the indicator 1930 When the specific area is selected, the enlarged video data is replaced and displayed on the main screen 1910 instead of the original video data. Further, for example, in accordance with the change of the position of the pointer 1932, the position of the indicator 1930 is also changed. Also, if a specific area to be enlarged is determined after the specific area enlargement mode is executed, for example, the original video data is displayed in the window 1920 at one time, but only the size is reduced. Furthermore, the main screen 1910 displays video data that is enlarged (more than 1 time, for example, 1.2 times, 1.5 times, or 2.0 times) only a specific area other than the original video data.

For example, the controller 1530 brightly adjusts the brightness of the area inside the indicator 1930 in the window 1920 and darkens the brightness of the area outside the indicator 1930, thereby easily .

Also, a ratio display bar including an enlargement button and a reduction button for changing the screen enlargement ratio exists in the main screen 1910. The controller 1530 receives the command for selecting one of the reduction button 1922 and the enlargement button 1924 from the external device 1940 using the pointer 1932 and stores the size of the indicator 1930 in correspondence thereto Adjust it to a preset ratio. The controller 1530 changes the shape of the pointer 1932 differently according to the command for selecting the reduction button 1922 and the enlargement button 1924. [ The ratio indicator / control bar including the reduction button 1922 and the enlargement button 1924 is called a second indicator and is distinguishable from the indicator 1930 described above.

Here, the minimum value of the ratio in accordance with the selection of the reduction button 1922 may be one, and the maximum value of the ratio in accordance with the selection of the enlargement button 1924 may be five times. Here, the maximum value of the enlargement ratio is not limited to 5 and is adjustable. If the enlargement ratio is less than 1, the image displayed on the screen is reduced.

For example, when the controller 1530 receives a command to select the shrink button 1922, it changes the shape of the pointer from the original shape 1932 to a - shape. When the controller 1530 receives the command for selecting the enlargement button, it changes the shape of the pointer from the original shape 1932 to the + shape.

Further, the window 1920 can be implemented as a PIP screen, and the size of the PIP screen is designed to be adjustable. For example, the controller 1530 clicks the edge portion and the corner portion of the PIP screen, and moves the command from the first point to the second point, which is different from the first point, to the external device ( For example, a remote controller), the size of the PIP screen can be adjusted.

Further, the controller 1530 can change the position of the PIP screen.

For example, the controller 1530 may click the first point of the PIP screen as a pointer and move the first point at the first point to a different second point in the first area Is received from the external remote controller, the position of the PIP screen can be changed. The PIP screen described here corresponds to the window 1920 shown in Fig.

For example, if the window 1920 continues to be displayed, it may be inconvenient for the user to watch the video data being played back. Accordingly, after a predetermined time (for example, three seconds) has elapsed, the controller 1530 switches the window and the indicator to the hidden state, and upon receiving the preset command from the external device 1940, Display it again on the PIP screen.

The controller 1530 switches the window and the indicator to the hidden state when the pointer 1932 is located at the right boundary line, the left boundary line, the upper boundary line, and the lower boundary line of the second area 1920, Upon receiving a specific command from the device 1940, the window 1920 is displayed again in the full screen 1910 as a PIP screen.

The controller 1530 moves the indicator 1930 using the pointer 1932 and changes the video data displayed on the main screen 1910 in accordance with the change in the position of the indicator 1930. For example, the video data in the area specified by the indicator 1930 and the video data enlarged and displayed on the main screen 1910 are the same and differ only in size (the main screen 1910 and the indicator 1930), and will be apparent to those skilled in the art. More specifically, for example, when the indicator 1930 in the window 1920 includes only a specific object, the main screen 1910 also displays video data including only a specific object, When compared to my video data, there is a difference in size only.

Therefore, by displaying the changed position and size of the indicator 1930 in real time, there is a technical effect that the enlarged specific area of the original video data can be checked more quickly.

To summarize again, when the specific area enlargement mode is executed, the original video data is output to both the main screen area 1910 and the window 1920. However, in the window 1920, video data reduced in size only is displayed. For specific area enlargement, a pointer 1932 may be located within the main screen 1910 or may be located within the window 1920. The specific area to be enlarged with the pointer 1932 as a center point is confirmed.

However, if the specific area to be enlarged is confirmed, the main screen 1910 displays video data in which a specific area is enlarged instead of the original video data. Further, due to the enlargement ratio adjustment or the like, the enlarged video data displayed on the main screen 1910 can be designed to return to the original video data. After the original video data is displayed again on the main screen 1910, a specific area to be enlarged by selecting any point in the main screen 1910 can be newly designated. Of course, it is also within the scope of the present invention to newly designate a specific area to be enlarged by using the indicator 1930 in the window 1920.

Further, when the enlargement / reduction ratio is adjusted by using the external device 1940 or the like while outputting enlarged video data on the main screen 1910, the size of the indicator 1930 in the window 1920 Design to change automatically. Therefore, the user has the advantage that it is easy to check which portion of the window 1920 the video data that is enlarged or reduced in the main screen 1910 in real time corresponds to.

The second indicators 1922 and 1924 shown in Fig. 19 are used for setting the magnification level. Further, the content output to the main screen 1910 is received through a tuner or via an external device. The external device corresponds to at least one of STB, PC, or cellular phone, for example.

The size of the indicator 1930 is automatically changed according to the magnification level selected through the second indicators 1922 and 1924.

Further, although not shown in FIG. 16, a person skilled in the art will be able to refer to FIG. 19 described above by receiving a first enlargement level for enlarging the displayed content, and based on the received first enlargement level, The method of claim 1, further comprising: displaying the magnification indicator having a display size; receiving a second magnification level for magnifying the displayed content; and based on the received second magnification level, And displaying the magnification indicator having a display size.

The window 1920 includes, for example, a Picture In Picture (PIP) window.

Moving the window 1920 in the main screen 1910 also belongs to another right scope of the present invention and in order to select another specific area of the content displayed in the window 1920, Moving the indicator 1930 also falls within the scope of other rights of the invention.

The indicator 1930 moves according to the pointer 1932 signal received from the remote controller 1940 and the size of the indicator 1930 is changed according to the wheel signal received from the remote controller 1940.

Increases the size of the indicator 1930 in accordance with the reduced magnification level 1922 while decreasing the size of the indicator 1930 in accordance with the increased magnification level 1924.

The indicator 1930 is implemented, for example, as a graphic image of a guide box that guides a specific area to be enlarged or enlarged.

The method further comprises the step of converting the coordinate information of the pointer moving according to the motion of the remote controller according to the video data of the content outputted on the main screen of Fig. For example, if the resolution information of the video data of the content corresponds to HD (High Definition), the step of scaling 0.66 times the coordinate information of the pointer, the resolution information of the video data of the content is FHD Scaling the coordinate information of the pointer by one when the resolution information of the video corresponds to UHD (Ultra High Definition), and if the resolution information of the video data of the content corresponds to UHD (Ultra High Definition) / RTI > In this regard, it will be described in more detail below with reference to FIG.

Controls the window 1920 and the indicator 1930 to disappear according to at least one or more commands received from the remote controller 1940 after a predetermined time has elapsed since the enlargement mode was executed. After the window and indicator are all disappeared, a graphical image is displayed to guide the enlargement mode being executed, and the graphic image includes information indicating an enlargement magnification. The window 1920 and the indicator 1930 are displayed again in response to a command for selecting the graphic image. In this regard, it will be described later in detail with reference to FIG. 31 to FIG.

Here, the memory 1550 corresponds to, for example, an external hard disk, an external USB memory, or a memory built in the multimedia device.

The controller 1530 displays the bar 2310 indicating the reproduction time point at the lower end of the first area 2300 in which the video data is displayed. For example, when the genre information of the video data corresponds to a sport, the controller 1530 displays a marking at a point of time (2312) at which a goal was scored and at a point (2314) at which people watched the most. The specific time points 2312 and 2314 can be collected through EPG information or web search. When the specific time points are selected, the specific area enlargement mode is automatically designed to be executed.

According to another embodiment of the present invention, the controller 1530 retrieves at least one video data stored in the memory 1550 and reproduces only a section in which the specific area enlargement function of the retrieved video data is executed.

For example, in video data in which a specific singer group composed of nine members including a first singer and a second singer is singing, the user may be interested only in a section in which the first singer and the second singer sing . Unlike the conventional time sheet function, the controller 1530 stores information on the section in which the specific area enlargement function is executed in the memory 1550 together with the video data.

The controller 1530 searches the memory 1550 for a section in which the specific area enlargement function has been executed and reproduces only the searched section.

Therefore, according to the present invention, there is an advantage that the user does not need to reproduce the entire section of the video data, since the section in which the specific area enlargement function is automatically searched is searched and only the searched section is reproduced.

According to another embodiment of the present invention, the controller 1530 divides the entire screen based on the number of times the specific area enlargement function has been executed in the video data temporarily stored in the memory. In each divided screen, the video data in which the specific area enlargement function is executed, that is, the video data enlarged only in the specific area, is designed to be output. For example, when the number of times of executing the specific area expanding function for one video data (broadcast program) is nine in total, the controller 1530 displays nine divided screens. The controller 1530 reproduces the sections in which the specific area enlargement function is executed, on the screen divided into nine sections.

Therefore, there is an advantage that the section in which the specific area enlargement function is executed can be confirmed more quickly.

FIG. 24 is a diagram illustrating switching between a full screen and a zoom screen according to an embodiment of the present invention.

As shown in Fig. 24, when the controller 1530 receives a specific command from the external remote controller, the controller 1530 changes the video signal sent to the first area and the video signal sent to the second area, Display.

Specifically, the video signal to be transmitted to the first area corresponds to the enlarged video data of the specific area, and the video signal to be transmitted to the second area corresponds to the original video data whose size is reduced.

Therefore, in the upper figure 2410 of Fig. 24, the video data in which the specific area is enlarged is displayed on the main screen, and the original video data in which only the size is reduced is displayed on the PIP screen. Specifically, the PIP screen displays the positions of the entire screen reduced in a certain ratio and the area enlarged in the entire screen.

In the lower figure 2420 of FIG. 24, the full screen is displayed on the main screen, and the screen on which the specific area is enlarged is displayed on the PIP screen.

Therefore, according to the embodiment of the present invention, there is an advantage that the original video data and the enlarged video data can be selectively switched to the full screen or PIP screen as needed.

FIG. 25 is a view showing enlargement of several points in a screen according to an embodiment of the present invention.

25, the controller 1530 receives a command specifying a plurality of points in the first area 2510 from an external remote controller through the communication module within a predetermined time in a state in which the specific area enlargement mode is activated , The PIP screen is automatically generated and displayed by the plurality of times.

For example, when the controller 1530 receives a command for selecting a specific point in three first areas 2510 within 3 seconds from the external remote controller through the communication module while entering the specific area enlargement mode, A PIP screen 2520, a second PIP screen 2530, and a third PIP screen 2540. [ Each PIP screen includes video data magnified around the three specific points.

According to an embodiment of the present invention, when a user wishes to view various points in a single screen, a plurality of points can be specified and displayed on a PIP screen in a specific portion of the screen.

In this case, when multiple people are in different positions on a single screen, it is possible to identify multiple people at the same time, to identify each specific individual, and to know details of clothes, watches, and accessories worn by the identified person , The user convenience is improved.

FIG. 26 is a view showing enlargement by selecting various points on a screen according to an embodiment of the present invention. Fig. 26 is an embodiment similar to Fig. 25, so that the difference will mainly be described, and those skilled in the art can supplement the Fig. 26 with reference to Fig.

For example, when the controller 1530 enters a specific area enlargement mode and receives a command for selecting three specific points within three seconds from the external remote controller through the communication module, the controller 1530 controls the first area The first sub screen 2620, the second sub screen 2630 and the third sub screen 2640 are displayed in an area excluding the first area 2610 by reducing the size of the first sub screen 2610 by 80% Each PIP screen includes video data magnified around the three specific points.

Compared with Fig. 25, Fig. 26 shows a solution for solving the problem that the original video data is blocked from the PIP screen. Particularly, according to the number of sub-screens 2620, 2630, and 2640, the size of the first area 2610 from which the original video data is output is also different.

FIG. 27 is a diagram for solving the case where the remote control coordinates and the input video coordinates do not match according to an embodiment of the present invention. In the process of implementing another embodiment of the present invention, the technical problems to be described later in Fig. 27 and the following should be solved.

As shown in FIG. 27, the remote control coordinates are 1920 x 1080 in the two-dimensional plane 2710, and the coordinate of the video signal may be 3840 x 2160 in the two-dimensional plane 2720. Here, the coordinates are not fixed and can be changed depending on the resolution of the input video signal and the device. The number of coordinates is not an absolute value, but can be changed to a relative value. The resolution refers to how many pixels are contained in one screen. The resolution is expressed as the number of pixels in the horizontal direction multiplied by the number of vertical pixels. That is, when the resolution is 1920 x 1080, the number of horizontal pixels is 1920 and the number of vertical pixels is 1080, which is represented by a two-dimensional plane coordinate.

For example, even if the user selects a P point of x = 1440 and y = 270 on the screen currently displayed by using the remote controller due to the mismatch between the coordinates of the remote controller and the video signal, the controller 1530 obtains x = 720 and y = 135 P 'point is selected.

Therefore, a difference occurs between the coordinates the user intended and the coordinates the controller 1530 recognizes.

Here, when transmitting the data to the display device, the external remote controller transmits data including coordinate information of the remote controller. The external remote controller and the display device are connected by wireless communication, and include RF communication and IR communication. In addition, the external remote control can be a mobile device including a smart phone and a tablet PC.

The controller 1530 scales the coordinate information of the external remote controller according to the video signal information of the contents.

Specifically, the controller 1530 detects changed video signal information when the video signal information of the content is changed, and scales the plane coordinates of the external remote controller received from the external remote controller based on the detected video signal information.

For example, if the remote control coordinates are 1920 x 1080 and the video signal resolution information of the content is 720P HD with 1280 x 720, the controller 1530 scales the received remote control coordinates based on the video signal information to 1280 x 720 Change it. When the resolution is HD, the scaling coefficient is 0.66.

If the video signal resolution information of the content is FHD of 1920 x 1080, the controller 1530 scales based on the video signal information. When the resolution is FHD, the remote control coordinates and the video signal information coordinates are the same, so that the scaling factor is 1.

If the video signal resolution information of the content is a UHD of 3840 x 2160, the controller 1530 scales the remote coordinate received based on the video signal information to 3840 x 2160. If the resolution is UHD, the scaling factor is 2.

28 illustrates solving the case where a specific area to be enlarged is out of a video output range according to an embodiment of the present invention.

As shown in an upper diagram (2810) of FIG. 28, when a specific area is enlarged with the point where the pointer is located as a center point, there arises a problem that an area not included in the original video data occurs.

Therefore, as shown in the lower diagram 2820 of FIG. 28, the specific area is enlarged by moving to another point 2824 instead of the point 2822 where the pointer is located. Compared with the top picture (2810) of FIG. 28, there is an advantage that only the area included in the original video data is enlarged.

FIG. 29 is a flowchart illustrating a method of dividing a screen into a predetermined number when outputting video data according to an embodiment of the present invention, enlarging a selected screen when a user selects one of the divided screens, Fig.

As shown in the upper diagram (2910) of Fig. 29, when the controller 1530 receives a specific command from the external remote controller, it divides one screen into nine images when outputting the video data. The controller 1530 enlarges and reproduces only the video data corresponding to the selected specific screen 2912 when the user receives a command from the external remote controller to select a specific screen 2912 from among the divided screens.

29, the controller 1530 reduces the original video data to a predetermined ratio and displays it in the second area 2924. In the first area 2920, And enlarges and displays the video data of the specific area selected in the area. Also, as described above, an indicator 2922 for guiding the enlarged specific area is displayed together in the second area 2924. [

30 is a diagram showing that the controller divides the screen into four, nine, or sixteen divisions according to user selection when outputting video data according to an embodiment of the present invention.

30, when the controller 1530 receives the specific command 3020 from the external remote controller 3010, the controller 1530 divides the screen into four parts (3030) and outputs it when the arbitrary video data is output, (3040), displays it, divides the screen into 16 parts (3050), and displays it. The number of divided screens may be set to a predetermined default value, or may be selectable by the user. By referring to the divided screen, the user can select a specific area of the video data to be enlarged.

If the magnification or reduction magnification of the video data displayed in the first area is changed according to at least one command received from the external device after the specific area enlargement mode is executed, 2 Automatically changes the size of the indicator in the area. Hereinafter, the details will be described later in detail with reference to FIG.

If the specific area to be enlarged is recognized in the first area in accordance with at least one command received from the external device after the specific area enlargement mode is executed, Automatically changes the center point of the indicator. Hereinafter, this will be described later in more detail with reference to FIG.

The controller 1530 controls the video data and the indicator in the second area to disappear according to at least one or more commands received from the external device after a predetermined time has elapsed since the specific area enlargement mode was executed do. Hereinafter, this will be described later in more detail with reference to FIG.

Further, the controller 1530 displays a graphic image that guides the execution of the specific area enlargement mode after all of the video data and indicators in the second area are disappeared, and the graphic image displays information indicating the enlargement magnification . Then, the controller 1530 is designed to display the video data and the indicator in the second area again according to a command to select the graphic image. Hereinafter, this will be described later in more detail with reference to FIG.

Figure 31 illustrates a process for adjusting the magnification factor during execution of a specific area magnification mode, in accordance with an embodiment of the present invention. It is also within the scope of the present invention for those skilled in the art to implement some other embodiments in conjunction with FIG. 31 with reference to the previous figures.

31, when the specific area enlargement mode is executed and the specific area to be enlarged is determined, the video data of the area specified by the indicator 3130 in the second area 3120 is stored in the first area 3110 ). As described above, the video data in the indicator 3130 and the video data in the first area 3110 correspond to each other and are the same but different in size.

Further, it is possible to transmit, to the multimedia device (EX: TV, STB), an instruction to further enlarge or reduce the video data being displayed in the first area 3110 by using the external device 3100 . For example, as shown in FIG. 31, a command to enlarge video data in the first area 3110 is generated through a specific button of the external device 3100 and is transmitted to the multimedia device.

Therefore, as shown in Fig. 31, the enlarged video data is output in the first area 3111 as compared with the previous first area 3110. [ It is a feature of the present invention that at least one of the position or the size of the indicator 3131 in the second area 3121 is automatically changed so as to correspond to the video data in the first area 3111.

32 illustrates a process for selecting an enlarged area during execution of a specific area enlargement mode, in accordance with an embodiment of the present invention. It is also within the scope of the present invention to those skilled in the art to implement some other embodiments as shown in Figure 32 with reference to the previous figures.

32, the same video data is output to the first area 3210 and the second area 3220 at the time when the specific area enlargement mode is first executed, not. The position of the indicator 3230 in the second area 3220 is designed to correspond to or correspond to a specific area last selected in the previously-executed specific area enlargement mode.

On the other hand, assuming such a situation, it is assumed that a specific region to be enlarged is selected using the external device 3200.

Therefore, as shown in FIG. 32, the original video data is continuously output to the second area 3221, as in the previous second area 3220, while the video data of the specific area is enlarged in the first area 3211, . However, at least one of the position or the size of the indicator 3231 in the second area 3221 is automatically changed, and as shown in FIG. 32, it is possible to correspond to a video data output from the first area 3211 The position or size of the indicator 3231 is automatically changed. In the case of such a design, there is an advantage that it is possible to more easily and quickly confirm which particular area of the original video data is enlarged and watched.

33 illustrates a process for disabling an associated indicator during execution of a specific area enlargement mode, in accordance with an embodiment of the present invention. It is also within the scope of the present invention that a person skilled in the art may implement some embodiments different from those of FIG. 33 with reference to the previous drawings.

33, after the specific area enlargement mode is executed, original video data is output to the second area 3330, and only the specific area is enlarged in the first area 3310 Video data is displayed. In addition, the indicator 3320 is changed in size and position in association with the first area 3310.

However, due to the video data and the indicator 3320 in the second area 3330, some of the enlarged video data is hidden by the video data and the indicator 3320 in the second area 3330. In order to solve such a problem, when the multimedia device receives a specific command after a preset time elapsing time (EX: 3 to 5 seconds) or from the external device 3300, the first area 3311 still has a specific area enlarged And the second area 3321 is designed so as not to display the indicator and original video data when compared with the previous second area 3320. [ Therefore, the user is expected to have a technical effect that only the video data in which the specific area is enlarged can be viewed in the first area 3311.

34 illustrates a process of redisplaying a related indicator that has disappeared during the execution of a specific area enlargement mode, according to an embodiment of the present invention. It is also within the scope of the present invention to those skilled in the art to implement some other embodiments than those of FIG. 34 with reference to the previous drawings. In particular, Fig. 34 assumes Fig. 33, which was described immediately before.

34 is similar to the first embodiment shown in Fig. 33 except that the first area 3410 outputs video data in which a specific area is enlarged. However, Lt; RTI ID = 0.0 > 3440 < / RTI > In particular, the second other indicator 3440 includes information indicating whether the video data being output in the first area 3410 is enlarged by several times as compared with the original video data.

If the second indicator 3440 is selected using the external device 3400, the second area 3430 again outputs the original video data and the indicator 3410 corresponding to the first area 3411 (3420) is displayed again.

According to an embodiment of the present invention, when a command for activating the screen enlargement mode is received from the external remote controller, a notification message and a pointer are displayed on the screen, and a specific portion of the main screen is displayed as a guide box The area specified by the guide box can be displayed on the full screen and the sub-screen in which the main screen is reduced in a predetermined ratio can be displayed as the PIP screen within the entire screen. As a result, It can be intuitively understood.

According to another embodiment of the present invention, the viewer can enlarge and view only a desired portion of the broadcast image, thereby improving user convenience.

According to another embodiment of the present invention, the user can easily adjust the position or magnification ratio of an area to be enlarged on the screen, thereby improving user convenience.

According to another embodiment of the present invention, when the screen enlargement mode is used, the user can easily recognize that the screen enlargement mode has been executed by changing the pointer of the screen, thereby improving user convenience.

According to another embodiment of the present invention, when the user clicks a specific point in the main screen showing the enlarged image, the center point of the screen enlargement area can be moved, and thus the screen enlargement area can be finely adjusted in a narrow area Thereby improving user convenience.

According to another embodiment of the present invention, the screen enlargement function is automatically executed in a specific genre such as sports and news, thereby improving user convenience.

According to another embodiment of the present invention, when the playback point is shifted to a point in time when the user wants to see again in conjunction with the time shift function, the user can view a desired portion in an enlarged image, thereby improving user convenience.

According to another embodiment of the present invention, when the screen enlargement function is executed, in some cases, the main screen and the PIP screen are switched and the user can view the original image on the enlarged screen, thereby improving user convenience.

According to another embodiment of the present invention, when there is a mismatch between the coordinates of the remote control and the video signal, the coordinates of the remote control are converted based on the coordinates of the video signal, thereby solving the problem of coordinate mismatch.

According to another embodiment of the present invention, when the guideline is out of the screen display area, the problem of moving out of the screen display area by moving the center point of the guideline can be solved, thereby improving user convenience.

1 to 34, it is assumed that the user mainly selects a specific area to be enlarged. On the other hand, in the following, FIG. 35 to FIG. 48, which will be described later, will explain an embodiment in which a specific area expected to be preferred by the user is automatically detected and only the detected area is enlarged. It is of course possible for those skilled in the art to combine at least two of the embodiments described in FIGS. 1 to 48 to implement other embodiments, which is also within the scope of the present invention.

35 is a flowchart illustrating in detail a process of automatically extracting a user-preferred specific area and enlarging only the extracted specific area according to another embodiment of the present invention.

As shown in FIG. 35, the display device according to another embodiment of the present invention extracts resolution information of broadcast video data (S3510), and determines a maximum value of the enlargement magnification according to the extracted resolution information S3520). In this regard, it will be described later in detail with reference to FIG. 37 to FIG.

Further, the display device determines whether there is a specific area that the user is expected to be interested in (S3530), and automatically enlarges the corresponding area if it exists (S3540). In this regard, it will be described later in more detail in Fig.

In addition, the display device determines whether a specific area exists in the caption of the video data (S3550), and if there is a specific area, enlarges the corresponding area automatically (S3540). In this regard, it will be described later in more detail in Fig.

Further, the display device determines whether or not a specific keyword set by the user is included in the video data (S3560), and if it exists, enlarges the corresponding area automatically (S3540). In this regard, the details will be described later in detail with reference to FIG.

The display device continuously or periodically tracks (traces) the user's line of sight (S3570), and if the tracked area is confirmed, automatically enlarges the determined specific area (S3540).

According to another aspect of the present invention, there is provided a display device including: at least one content receiving unit for displaying video data corresponding to the received at least one content on a main screen of the display device; Adjusts the enlargement ratio of the specific area and controls the range of the enlargement ratio according to the resolution information of the video data.

In particular, it is designed to further include a step of converting coordinate information of a pointer moving according to the motion of the remote controller according to the resolution information of the video data. More specifically, for example, when the resolution information of the video data of the content is HD (High Definition), scales 0.66 times the coordinate information of the pointer, and when the resolution information of the video data of the content corresponds to FHD (Full High Definition), the coordinate information of the pointer is multiplied by 1 And scales the coordinate information of the pointer by two if the resolution information of the video data of the content corresponds to UHD (Ultra High Definition). In this regard, previously described in detail in FIG. 27 above.

15 and FIG. 35, a display device according to another embodiment of the present invention includes a tuner 1510, a memory 1550, a display module 1540, and a controller 1530. The tuner 1510 receives at least one content and the display module 1540 displays the video data corresponding to the received at least one content on the main screen of the display device and the controller 1530 ) Adjusts the magnification ratio of a specific area in the video data. In particular, the controller 1530 is designed to control the magnification range according to the resolution information of the video data.

36 shows a first embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention. According to the first embodiment, the display device 3600 automatically detects and magnifies the group of specific areas 3610, 3620 that the user is expected to be interested in.

For example, the EPG recognizes that the currently tuned channel is a sports channel through the channel list of the EPG. Further, it is detected through the program list of the EPG whether or not the program being broadcast on the currently tuned channel is a soccer game.

Two solutions for detecting the specific areas 3610 and 3620 shown in FIG. 36 are possible. First, the image processing enlarges and displays the area where the soccer ball is located, the area around the goalpost or the area where the corner kick is made. Second, when a voice called "corner kick" is detected in the audio signal output through the audio processing, the area surrounding the corner kick is enlarged and displayed.

37 to 39 show a process of adjusting the maximum value of the enlargement magnification based on the resolution information of the broadcast video data, according to another embodiment of the present invention.

When enlarging a specific area automatically or manually, if the enlargement is done infinitely, the screen may be broken. 37 to 39 are solutions for solving such a problem.

First, a display device according to another embodiment of the present invention analyzes resolution information of video data of an input signal. For example, the signal may be input through a tuner, but the present invention is not limited to a broadcast signal input through a tuner.

37, when the resolution information of the video data of the signal received by the display device 3700 corresponds to the HD picture quality, a message 3710 indicating that the specific area enlargement can be performed only up to twice is displayed. Of course, it can also be implemented as audio.

38, when the resolution information of the video data of the signal received by the display device 3800 corresponds to Full HD image quality, a message 3810 indicating that the specific area enlargement can be performed only up to 8 times is displayed on the display do. Of course, it can also be implemented as audio.

39, when the resolution information of the video data of the signal received by the display device 3900 corresponds to the UHD image quality, a message 3910 indicating that the specific area enlargement can be performed only up to 16 times is displayed . Of course, it can also be implemented as audio.

40 shows a second embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention. Most users can easily predict the character portion in the subtitles, but the numerical portion can not be predicted easily. FIG. 40 is an embodiment for solving such a problem.

As shown in FIG. 40 (a), the display device 4000 according to the related art displays all the characters and numbers in the subtitles at the same size, but it is difficult for the user to particularly predict the numerical portion.

In order to solve such a problem, the display device is designed to judge whether or not video data currently being output includes caption data, and enlarge display by considering the area where the caption data is displayed as a specific area.

Therefore, as shown in FIG. 40B, the display device 4010 enlarges and displays the area 4011 including only the numbers in the subtitles, and has the technical effect of solving the existing problems.

FIG. 41 shows a third embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention. In the embodiments of Figs. 1 to 34, there is a problem in that the area to be enlarged must be specified each time the user needs it. FIG. 41 is an embodiment to solve such a problem.

That is, the user using the display device according to another embodiment of the present invention sets in advance predetermined keywords (ex: Kill, Economy, LG sales, Apple stock, etc.) desired to be automatically enlarged, You are storing one keyword.

As shown in (a) of FIG. 41, it is assumed that the display device 4100 outputs an arbitrary broadcast, and a subtitle including a specific keyword (Kill) preset by the user is displayed. According to the related art, no response occurs at this time, whereas the display device according to another embodiment of the present invention stores a specific keyword in the memory, so that the display device 4110 as shown in FIG. 41 (b) Only the specific keyword 4111 is automatically enlarged and displayed. Therefore, there is a technical effect that the user does not need to perform the enlargement function every time.

Meanwhile, although not shown in the drawings, it is also possible to implement another embodiment by applying the known eye tracking technology to the present invention. For example, although not shown in FIG. 15, the display device additionally includes a camera and a line-of-sight tracking module. Therefore, the user's eyes located around the display device are tracked, and the specific area to be enlarged is determined according to the tracking result. That is, there is a technical effect that the user can easily specify the area to be enlarged without using the remote controller.

Figure 42 illustrates a solution for selecting a specific area of the user's preference, in accordance with another embodiment of the present invention.

As shown in FIG. 42, the display device 4200 maps the numbers of the areas 4201, 4202, and 4203 when the in-screen video data is divided into a plurality of areas. Therefore, the user can simply push the numeric key of the remote control to select a specific area to enlarge.

It is also within the scope of the present invention to design such that each area is sequentially enlarged in the order of the numbers shown in FIG. 42, or that all selected areas are enlarged at the same time. When the user presses the right arrow button on the remote controller while the first area 4201 is enlarged, the second area 4202 is enlarged. When the right arrow button is pressed once more, the third area 4203 is enlarged. . Accordingly, it is easy to search for an area to be enlarged.

43 and 44 illustrate a fourth embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention.

43 and 44 are designed so that the enlarged area varies depending on the type of subtitles. That is, as shown in FIG. 43, when the caption is static, the enlarged area of the lens shape automatically moves from the right side 4310 to the left side 4311.

On the other hand, when the caption is dynamic as shown in FIG. 44, the first region 4410 in which the movement of the caption starts is regarded as the enlarged region, and a graphic image of the lens shape is output.

45 and 46 illustrate a fifth embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention.

As shown in FIG. 45, the zoom factor is designed to vary according to the distance between the display device and the user. That is, the memory of the display device stores information having a different zoom magnification depending on the distance between the user and the display device recognized through a camera or the like. For example, when the distance between the user and the display device is in the first range, the first zoom factor corresponds to twice, and when the distance between the user and the display device is in the second range, the second zoom factor corresponds to four times And the first zoom factor corresponds to 8 times when the distance between the user and the display device is in the third range.

Therefore, assuming that the information shown in Fig. 45 is stored in the memory, if the distance between the user and the display device is within the first range (for example, within 0 to 2 meters), as shown in Fig. 46 (a) , The subtitle is displayed on the screen in a state in which the subtitle is automatically magnified twice.

On the other hand, when the distance between the user and the display device is in the second range (for example, within 2 meters to 10 meters) as shown in Figure 46 (b), the subtitle is automatically enlarged four times Is displayed. Of course, the subtitle is exemplified in FIG. 46, but it is also applicable to breaking news and stock information.

47 shows a sixth embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention. Users who can not hear the sound tend to deduce the contents of the conversation through the mouth shape of the speaker.

The entire face 4710 or the mouth 4720 of the in-screen person is detected as shown in Fig. 47 (a), and only the face 4711 or 4720 is enlarged as shown in Fig. 47 (b) Or the mouth enlarged area 4721 is displayed. It is also within the scope of the present invention to design such that it can be started by the user's choice or automatically when a broadcast of a news category is outputted.

48 shows a seventh embodiment of automatically extracting a user-preferred specific area according to another embodiment of the present invention. An embodiment in which a user is zoomed out of an area of no interest and automatically zooming in on the remaining area will be described with reference to FIG.

As shown in FIG. 48 (a), according to the related art, the stock information 4810 that the user is not interested in continuously occupies a small area.
