1, a service system includes a content provider 10, a service provider 20, a network provider 30, and a Home Network End User (HNED) (Customer) 40. Here, the HNED 40 includes, for example, a client 100, i.e., a digital device according to the present invention.

The content provider 10 produces and provides various contents. As shown in FIG. 1, the content provider 10 may include a terrestrial broadcast sender, a cable SO (System Operator), a MSO (Multiple SO), a satellite broadcast sender, Personal content providers, and the like. On the other hand, the content provider 10 can produce and provide various services and applications in addition to the broadcast content.

The service provider 20 provides service packetizing of the content produced by the content provider 10 to the HNED 40. [ For example, the service provider 20 packages at least one of the first terrestrial broadcast, the second terrestrial broadcast, the cable MSO, the satellite broadcast, the various internet broadcast, and the contents produced by the application for service, (40).

The service provider 20 provides services to the client 100 in a uni-cast or multi-cast manner. Meanwhile, the service provider 20 can transmit data to a plurality of clients 100 registered in advance, and an Internet Group Management Protocol (IGMP) protocol can be used for this purpose.

The above-described content provider 10 and the service provider 20 may be the same entity. For example, the service provided by the content provider 10 may be packaged and provided to the HNED 40, thereby performing the function of the service provider 20 or vice versa.

The network provider 30 provides a network for exchanging data between the content provider 10 and / or the service provider 20 and the client 100.

The client 100 is a consumer belonging to the HNED 40. The client 100 constructs a home network through the network provider 30 to receive data and stores data related to various services and applications such as VoD and streaming / RTI >

Meanwhile, the content provider 10 or / and the service provider 20 in the service system can use conditional access or content protection means for protecting the content to be transmitted. Accordingly, the client 100 can use a processing means such as a cable card (or a POD: Point of Deployment), a DCAS (Downloadable CAS) or the like in response to the restriction reception or the content protection.

In addition, the client 100 can use the two-way service through the network. Accordingly, the client 100 may rather perform the function or role of the content provider, and the service provider 20 may receive the content and transmit the same to another client or the like.

In FIG. 1, the content provider 10 and / or the service provider 20 may be a server that provides a service described later in this specification. In this case, the server may also mean to own or include network provider 30 as needed. The service or service data includes an internal service or an application, as well as a service or an application received from the outside, and the service or the service includes a service for a Web OS-based client 100 Or application data.

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 stored service information can be read out and used by the corresponding configuration, for example, by a user's request.

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

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. In addition, the service control manager 209 can initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

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

The SI & meta data database 211 stores service information decoded by the SI decoder 204, meta data managed by the meta data manager 212, and information necessary for selecting a service provider provided by the service discovery manager 210 . In addition, the SI & meta data database 211 may store set-up data for the system and the like.

The SI & meta data database 211 may be implemented using a non-volatile RAM (NVRAM) or a flash memory.

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

The processed image frame can be displayed on the display section 351. [

The image frame processed by the camera 321 may be stored in the memory 360 or transmitted to the outside via the wireless communication unit 310. [ At least two cameras 321 may be provided depending on the use environment.

The microphone 322 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 312 in the case of the communication mode, and output. The microphone 322 may be implemented with various noise reduction algorithms for eliminating noise generated in receiving an external sound signal.

The user input unit 330 generates input data for user's operation control of the terminal. The user input unit 330 may include a key pad, a dome switch, a touch pad (static pressure / static electricity), a jog wheel, a jog switch, and the like.

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 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.

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's Kit (NDK) / QT layer (Enyo framework / NDK / QT layer), and Application layer in the uppermost 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 implemented on the basis of regular HTML5, CSS (Cascading Style Sheets), and JavaScript.

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 at the time of 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. In the above description, the media server supports operations such as 'setchannel', 'channelup', 'channeldown', 'channeltuning', and 'recordstart' in relation to the TV service, ',' stop ', and so on, so that they can support different operations for both, and can be 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 '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 block diagram illustrating a mobile device and at least one digital device in accordance with one embodiment of the present invention.

Further, the controller 1304 controls the display module 1301 to display image data identifying each of the at least one or more detected digital devices 1310, 1320, and 1330. In particular, in contrast to the prior art simply listing connectable devices, the present invention is a technique related to how to capture, receive, and generate the image data. A first embodiment for listing a connectable digital device according to a predetermined priority will be described later in detail with reference to FIG.

For example, unlike the prior art, the image data is received from each digital device 1310, 1320, 1330.

Further, the image data received from the first digital device 1320 having the display corresponds to the image data captured by the current screen being output through the display 1322, while the second digital device The image data received from the image processing units 1310 and 1330 corresponds to the image data previously stored in the memory of the second digital device. Meanwhile, a second embodiment using different image data according to the presence or absence of display of a digital device connectable to a mobile device will be described later in detail with reference to FIG. 15 and FIG.

When specific image data among image data identifying each of the at least one detected digital device is selected through the touch sensor 1302, the controller 1304 notifies the specific digital device corresponding to the specific image data And transmits at least one of the video data and the audio data.

Further, the controller 1304 may transmit the video data or the audio data for notification to the specific digital device corresponding to the specific image data only when the specific image data is selected below the predetermined pressure through the touch sensor 1302 And at least one of the data is transmitted. A third embodiment in which a digital device connectable to a mobile device generates a feedback signal will be described later in detail with reference to FIG. 17 and FIG.

The display device 1320 includes a tuner 1321, a display module 1322, a speaker 1323, a wireless communication module 1324, and a controller 1325 according to an exemplary embodiment of the present invention.

The tuner 1321 receives a broadcast signal, the display module 1322 outputs video data included in the received broadcast signal, and the speaker 1323 receives audio data included in the received broadcast signal Output.

The wireless communication module 1324 is designed to communicate with the mobile device 1300 and the controller 1325 controls the tuner 1321, the display module 1322 and the wireless communication module 1324.

Particularly, the controller 1325 transmits the image data captured by the display module 1322 to the mobile device 1300 in response to the first request signal received from the mobile device 1300, Lt; / RTI > In particular, the first request signal corresponds to a probe request used in step S1901 described later with reference to FIG. 19, for example.

Further, the controller 1325 may receive data indicative of the particular digital device selected through the mobile device 1300 corresponding to the display device, corresponding to the second request signal received from the mobile device 1300 And outputs the output signal. In particular, the second request signal corresponds to the Current Location Request used in step S1905 described later with reference to FIG. 19, for example.

The data to be displayed may be output through at least one of the display module 1322 and the speaker 1323, for example.

Therefore, according to an embodiment of the present invention, a mobile device can list up a connectable digital device having a high priority based on at least one of the same network, existence of connection history, and signal strength among digital devices searched through a wireless network .

Further, according to another embodiment of the present invention, by designing the searched device (digital device) to capture a screen being output and transmitting the screen to the searched device (mobile device), the mobile device can display the current state of the connectable digital device There is a technical effect that can be confirmed in real time. However, it is another feature of the present invention that, in consideration of a digital device without a display, in this case, a photograph of the corresponding model is transmitted.

According to another embodiment of the present invention, when a searched device is selected, a specific indication is displayed on the screen of the searched device to give a feedback effect. However, another feature of the present invention is that, in consideration of a digital device without a display, in this case, it is designed to generate specific audio data as a feedback signal.

As a result, there is a technical effect of increasing the processing speed of connecting to a specific digital device using a mobile device and increasing the accuracy of guaranteeing connection to a specific digital device desired by the user.

14 shows a process of listing a plurality of digital devices connectable with a mobile device according to a predetermined priority according to the first embodiment of the present invention.

As shown in FIG. 14, when the mobile device 1400 turns on the wireless network function, an ID identifying each of a plurality of connectable digital devices 1410, 1420, 1430, 1440, 1450, 1460 is displayed. Unlike the prior art, however, the list order is designed to be automatically changed according to a predetermined priority in order to optimize the user's needs.

For example, for each of the retrieved devices (digital devices), priority is given to each searched device by checking whether they are connected through the same network, whether or not there is a previously connected history, and signal strength.

More specifically, for example, a digital device having a history (history) connected to the same network and having a previously connected history is given the highest priority, and if there are a plurality of digital devices having the same condition, .

Furthermore, when displaying each of the connectable digital devices, it is also within the scope of the present invention to adjust not only the position but also the font size and color of the name or ID corresponding to each digital device.

The first digital device 1410 and the second digital device 1420 are in the same network and have a connection history, but are determined to be the highest priority because the signal strength of the first digital device 1410 is higher.

The third digital device 1430 and the fourth digital device 1440 do not have a previous connection history but exist in the same network. However, since the signal strength of the third digital device 1430 is higher, it is determined to have a relatively high priority.

Finally, since the fifth digital device 1450 and the sixth digital device 1460 do not exist in the same network and have no connection history, only the signal strengths are compared. For reference, the "-digit dBm" unit, which indicates the signal strength, means that the larger the number, the weaker the signal strength.

15 shows a GUI for displaying captured image data identifying a plurality of digital devices connectable with a mobile device, according to a second embodiment of the present invention.

As described above, one of the problems in the related art is that it is difficult for the user to display a desired digital device by simply displaying the name of the connectable digital device. Even the same name is displayed for multiple connectable digital devices.

On the other hand, according to the second embodiment shown in FIG. 15, when the mobile device 1500 performs a wireless communication network function (for example, Wi-Fi on), each of the digital devices 1510, 1520, 1530, 1540, 1550 , 1560) of the current output image.

The mobile device 1500 displays the current captured image data 1511 of the first digital device 1510 and the current captured image data 1511 of the fourth digital device 1540 when displaying the connectable external digital device, Displays the image data 1541, and displays the currently captured image data 1551 of the fifth digital device 1550. The first digital device 1510, the fourth digital device 1540 and the fifth digital device 1550 described above are possible because they have a display or a screen.

However, for a digital device that does not have a display or a screen, it can be solved by receiving and displaying a representative model photograph stored in each memory.

For example, when displaying a connectable external digital device, the mobile device 1500 may include a representative model photograph (image data) (e.g., a photograph) representative of the appearance received from the second digital device 1520 (Image data) 1531 indicating the appearance received from the third digital device 1530 (for example, a refrigerator), and the sixth digital device 1560 (Image data) 1561 for displaying an appearance received from a projector (for example, a projector).

Further, there is a possibility that the screen displayed on the digital device having the display and the captured image data displayed on the mobile device 1500 may vary considerably after a lapse of a predetermined time. In order to solve such a problem, the mobile device 1500 of the present invention designates the update option 1501 so that the captured image data is updated in real time. Furthermore, there is a technical effect that unnecessary data transmission / reception can be reduced by designing not to transmit an update request signal to a digital device without a display.

The specific data format required for implementing the above-described embodiment in FIG. 15 will be described later with reference to FIG.

Figure 16 illustrates a process for displaying captured image data identifying each of a plurality of digital devices connectable with a mobile device, according to a second embodiment of the present invention.

In order for two devices (for example, a mobile device and a digital device) to search (wireless communication connection) with each other, when a device to be searched broadcasts a packet called probe request, the device receiving the probe request transmits a probe response And transmits the packet to the mobile device as a device to be searched.

In the probe response packet, the mac information, the listen channel information, and the device name of the corresponding device are included. In particular, according to the embodiment of the present invention, it is designed to transmit the captured image data of the current screen together.

That is, as shown in FIG. 16A, the mobile device 1600 broadcasts a probe request packet (S1601). Each digital device 1610 that receives the packet is designed to transmit a packet called a probe response to the corresponding mobile device 1600. In particular, FIG. 16 (b) illustrates the information included in the probe request and the information included in the probe response, but it is also within the scope of the present invention to design some modifications according to needs of those skilled in the art.

However, even in the above-described embodiment, if the same channel is being watched on, for example, a plurality of TVs, the same captured image data will be displayed on the mobile device. In such a case, it is expected that the user will have difficulty in specifying the TV to be connected. The solution for solving this will be described later in more detail in Fig. 17 and Fig.

17 is a diagram for explaining a process of generating a different feedback signal depending on whether a digital device connectable to a mobile device is displayed according to the third embodiment of the present invention.

The third embodiment is advantageous in that when a specific device to be connected is selected, a specific indication is displayed on the selected device, thereby giving a feedback effect in advance.

As shown in Fig. 17 (a), the mobile device 1700 displays a plurality of connectable digital devices. At this time, when a specific digital device is selected, the mobile device 1700 is designed to transmit a specific packet to the selected specific digital device.

For example, when selecting the specific TV 1701 shown in FIG. 17A, the TV 1710 receiving the specific packet can communicate with the mobile device 1700 as shown in FIG. 17B And displays a message 1711 to the user on a predetermined area of the screen. However, the problem solving of a digital device in which a display or a screen does not exist is shown in Fig. 17C.

That is, when the specific projector 17012 shown in FIG. 17 (a) is selected, the projector 1720 receiving the specific packet transmits the audio data indicating that the projector 1720 can communicate with the mobile device 1700 as shown in FIG. There is a technical effect that the user can more quickly confirm whether the device to which the device to be connected is a device.

17, the case of selecting a specific device is not separately described. However, only when a touch is recognized under a predetermined strength (pressure), it is implemented as shown in FIG. 17 (b) or (c) It is also within the scope of the present invention to design a communication connection with the digital device immediately without a feedback signal.

FIG. 18 is a diagram for explaining a process of changing IDs identifying connectable digital devices according to the strength (or pressure) of a touch recognized by the mobile device according to the third embodiment of the present invention.

As shown in Fig. 18 (a), the mobile device 1800 lists the digital devices connectable to the wireless communication. At this time, when the user 1802 touches the ID 1801 indicating the specific digital device and the recognized touch pressure is equal to or less than a preset threshold value, the selected specific digital device 1810 determines that the communication connection is possible And outputs the message 1811 in video form.

On the other hand, as shown in FIG. 18 (b), the mobile device 1850 lists the digital devices connectable to the wireless communication. At this time, when the user 1852 touches the ID 1851 indicating the specific digital device and the recognized touch pressure exceeds the predetermined threshold value, the selected specific digital device does not react and the mobile device 1850 also displays the captured image data 1853 of the screen currently being output by the particular digital device in addition to the ID 1851 that displays the particular digital device.

19 is a flowchart illustrating a signal processing process of a mobile device and a digital device according to an embodiment of the present invention.

In order for the two devices 1900 and 1910 to be searched, the device 1900 broadcasts a probe request packet (S 1901). The device 1910 receiving the probe request searches for a packet called a probe response I.e., the mobile device 1900 (S1902). Unlike the prior art, the packet used in step S1902 includes captured image data of a screen that the digital device 1910 is currently outputting.

Accordingly, the device (mobile device) 1900 receiving the probe response can know information such as the MAC information, the listen channel, and the device name of the corresponding device based on the information in the packet, (S1903). As described above, unlike the prior art, the displayed list is designed to include the currently captured image data of the connectable digital device.

If the name of the specific device is mildly touched within the searched list (S1904), the mobile device 1900 transmits a new packet called Current Location Request to the corresponding digital device 1910 (S1905).

The device 1910 receiving the new packet of Current Location Request generates a notification message on the screen (S1906) and transmits the Current Location Response to the mobile device 1900 (S1907). If you have a digital device that does not have a screen, you can solve the expected problem by designing it to send a Current Location Response packet after a beep.

20 is a flowchart illustrating a method of controlling a mobile device according to an embodiment of the present invention. With reference to the previous drawings, those skilled in the art can supplement the flow chart shown in Fig.

The mobile device according to an embodiment of the present invention performs wireless communication (S2010), and displays image data identifying each of at least one or more digital devices capable of communicating through the wireless communication performed (S2020).

The mobile device determines whether specific image data among the image data identifying each of the at least one or more digital devices is selected (S2030).

If the determination result is YES, at least one of video data or audio data for notification is transmitted to a specific digital device corresponding to the specific image data (S2040).

Although not shown in FIG. 20, according to another embodiment of the present invention, it is possible to further include receiving the image data from each of the digital devices.

20, according to another embodiment of the present invention, the image data received from the first digital device having the display may correspond to the captured image data of the current screen being output through the display And the image data received from the second digital device having no display corresponds to the image data previously stored in the memory of the second digital device.

13 to 20, a process of capturing and outputting a screen currently being output in each digital device in the process of searching for an external digital device connectable to a wireless communication according to an embodiment of the present invention has been described in detail have.

21, which will be described later, describes a process of reflecting the actual position of each digital device in the process of searching for an external digital device capable of wireless communication connection, according to another embodiment of the present invention I will. Of course, those skilled in the art can combine the embodiment described in FIGS. 13 to 20 with another embodiment described later in FIGS. 21 to 29, which is also within the scope of the present invention.

FIG. 21 shows a location where a mobile device and a plurality of digital devices actually exist according to another embodiment of the present invention.

As shown in FIG. 21, a plurality of digital devices are located in a house or a building. Accordingly, the mobile device 2100 according to another embodiment of the present invention may include a first speaker 2110, a second speaker 2120, a TV 2130, an STB 2140, a notebook 2150, And wireless communication is possible. However, according to the related art, devices that can be connected only in a list form are displayed without considering the actual physical position of each digital device, and it is difficult for a user to determine a desired specific digital device. Solutions for solving this will be described below with reference to FIG. 22 and FIG.

22 shows a GUI in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

First, the mobile device 2200 according to another embodiment of the present invention displays each of its location 2201 and the locations of other connectable digital devices in the form of a map, as shown in FIG.

The functions of the respective components will be described in detail with reference to FIG.

The touch sensor 1302 senses a user's touch and the wireless communication module 1303 is designed to be capable of communicating with at least one digital device 1310, 1320, 1330.

The controller 1304 controls the display module 1301, the touch sensor 1302 and the wireless communication module 1303, and in particular, the controller 1304 controls the wireless communication module 1303, A display module (1301) for controlling the display module (1301) to display first image data identifying each of the at least one or more detected digital devices and a second image identifying the mobile device Display the data. Here, the image data may be a captured image of a screen currently being output by each device, or may simply correspond to a device name. Further, the first image data corresponds to each of the digital devices 2211, 2221, 2231, 2241, and 2251 shown in FIG. 22, and the second image data corresponds to the mobile device 2201 shown in FIG. 22 .

Particularly, the feature of the present invention resides in that the position where the first image data and the second image data shown in Fig. 22 are displayed is changed according to the signal intensity recognized in the course of detec- tion of each of the digital devices by the mobile device Change.

An embodiment for indicating the position of each digital device capable of communicating with the mobile device according to the signal strength will be described later in more detail in Fig. However, an embodiment for supplementing the above will be described later in more detail with reference to FIG.

Further, the touch sensor 1302 shown in FIG. 13 is designed to recognize a command for selecting a specific digital device among at least one or more digital devices 1310, 1320, 1330 connectable via the wireless network.

The controller 1304 controls the wireless communication module 1303 to transmit the first message to the specific digital device if the specific digital device is selected to be equal to or less than a predetermined touch pressure. The first message corresponds to, for example, a command that instructs the specific digital device to output only an audio signal having a relatively small amount of data.

On the other hand, when the specific digital device is selected to exceed the predetermined touch pressure, the controller 1304 controls the wireless communication module 1303 to transmit a second message to the specific digital device, The second message is characterized by being different. The second message corresponds to, for example, a command that instructs the specific digital device to output a specific video signal (ex: device name). A more specific embodiment will be described later in more detail in Fig.

Further, as shown in FIG. 22, the mobile device 2200 according to another embodiment of the present invention provides an additional optional function.

When the first option 2281 is selected, wireless communication connectable digital devices 2211, 2221, 2231, 2241, and 2251 are displayed as shown in FIG. 22, and the position of each digital device, unlike the prior art, . For example, the higher the signal strength with the mobile device 2201, the closer it is displayed to the mobile device 2201.

When the second option 2282 is selected, a remote controller-related application capable of controlling the selected digital device is downloaded.

When the third option 2283 is selected, the selected digital device is designated as the source device, while when the fourth option 2284 is selected, the selected digital device is designated as the sink device. Therefore, even if the user does not directly control the source device and the sink device, it is possible to designate the source device and the sink device as a mobile device and design a mirror cast connection.

23 shows a fourth embodiment in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

As shown in FIG. 23 (a), the mobile device 2300 according to an embodiment of the present invention displays external digital devices 2301 and 2302 capable of wireless communication. However, it is difficult for the user to match the name of the digital device displayed on the mobile device 2300 with the actual external digital devices 2310, 2320 and 2330 only by using the simple name.

Thus, for example, if the name 2301 of a particular digital device is touched below a predetermined pressure, the corresponding digital device 2320 outputs a beep or any audio signal 2321. To implement this, the mobile device 2300 is designed to transmit the command to the selected particular digital device 2320.

Meanwhile, as shown in FIG. 23B, the mobile device 2350 according to an embodiment of the present invention displays external digital devices 2351 and 2352 capable of wireless communication. However, from the user's point of view, it is difficult to match the name of the digital device displayed on the mobile device 2350 with the actual external digital devices 2360, 2370, and 2380 only by using the simple name.

Thus, for example, if the name 2352 of a particular digital device is touched to a preset pressure, the corresponding digital device 2350 outputs a specific video signal 2381 (ex: device name). To implement this, the mobile device 2350 is designed to transmit the command to the selected particular digital device 2380.

FIG. 24 shows a fifth embodiment in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

As shown in FIG. 24A, when the mobile device 2100 according to another embodiment of the present invention searches for a digital device capable of wireless communication in the first position, as shown in FIG. 24B (b) Digital devices 2401 capable of wireless communication based on signal strength are displayed on the basis of a mobile device.

24 (a), when the mobile device according to another embodiment of the present invention recognizes the touch of the refresh button 2450 at the second position, as shown in FIG. 24 (c) It is possible to confirm that the wireless communication enabled digital devices 2411 according to the signal strength are updated on the basis of the mobile device of the changed position as described above. However, when designing in this way, some errors may occur with the actual physical location of the digital devices. A solution for solving this will be described later in Fig.

FIG. 25 shows a sixth embodiment in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

25, the mobile device 2500 according to another embodiment of the present invention may include a digital device 2511, 2512, 2513, 2514, 2515, 2516 (hereinafter, referred to as " ) Can be manually moved and stored in the memory. It can be confirmed that the map 2510 including all of the positions of the digital devices described above is slightly more similar to the actual position illustrated in FIG. 24 (a). Further, since the adjusted map 2510 is stored in the memory, there is an advantage that the user need not change again. However, the digital device may disappear from its original place, and a solution for solving the problem will be described later with reference to FIG.

FIG. 26 shows a seventh embodiment in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

First, suppose that the B digital device and the F digital device disappear in Fig. Even if any one of the wireless communication-enabled digital devices stored in the memory is searched, a map stored in the memory is displayed.

However, if it is ascertained that any digital device is not capable of wireless communication, the mobile device 2600 according to another embodiment of the present invention may include the non-scanned digital devices 2610 and 2620, It is designed to only display a dotted line or to display a message to turn on the power or to turn on the wireless communication device.

Fig. 27 shows an eighth embodiment in which a mobile device according to another embodiment of the present invention displays a plurality of digital devices according to their locations.

When there are a large number of digital devices capable of wireless communication in the home, there is a limitation in displaying them in the portrait mode of the mobile device. A solution to this problem corresponds to the eighth embodiment of FIG.

For example, when the mobile device 2700 searches for a digital device capable of wireless communication and is searched for a predetermined number (for example, four) or less, 2702, 2703, and 2704, respectively. The location of the digital devices is determined by the signal strength with the mobile device 2701.

On the other hand, when the mobile device 2700 searches for a digital device capable of wireless communication, if it is searched for more than a predetermined number (for example, four), the digital devices (2702, 2703, 2704, 2705, 2706, 2707). The location of the digital devices is determined by the signal strength with the mobile device 2701.

23, when the mobile device 2800 recognizes a touch input for selecting a particular digital device capable of wireless communication, the mobile device 2800 transmits a probe request signal to the particular digital device 2810 (step < RTI ID = 0.0 > S2801). The probe request signal includes a command for outputting a specific audio or video signal.

In response to the received probe request signal, the digital device 2810 displays its name or simply outputs a blinking LED signal or a specific sound (S2802).

Meanwhile, the digital device 2810 transmits a probe response signal to the mobile device 2800 (S2803), and the mobile device 2800 receiving the probe response signal displays the guide message (S2804). The guide message includes at least one of, for example, "Find a device displaying a name "," Look for a device whose LED signal flashes ", or "Look for a device that outputs a specific sound ".
