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.

[ 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 receives the key input regarding the channel selection from the user, and transmits the key input signal to the service manager 213.

The service manager 213 controls the manager associated with the service such as the service delivery manager 203, the service discovery manager 210, the service control manager 209, and the metadata manager 212.

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

The service discovery manager 210 provides information necessary for selecting a service provider providing 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 uses RTSP when selecting a service such as VOD Service selection and control. 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 the service information decoded by the SI decoder 204, the meta data managed by the meta data manager 212, and the information necessary for selecting a service provider provided by the service discovery manager 210 do. 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 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.

For example, the formatter 560 may output R, G, and B data signals, and the R, G, and B data signals may be output as low voltage differential signals (LVDS) or mini-LVDS . If the output of the input frame rate converter 555 is a 3D video signal, the formatter 560 may configure and output the 3D format according to the output format of the display unit to support the 3D service through the display unit.

On the other hand, the voice processing unit (not shown) in the control unit can perform the voice processing of the demultiplexed voice signal. Such a voice processing unit (not shown) may support processing various audio formats.

For example, the data processing unit can decode the demultiplexed data signal even when it is coded. Here, the encoded data signal may be EPG information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel.

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

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.

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

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 the 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, service which is differentiated by manufacturer, service which is manufacturer differentiated, Web OS common service and JavaScript, and is used through Node.js Node.js service.

The application layer can 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 according to 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 native application based on Qt, and includes a basic application provided with the Web OS platform such as a card view, a home dashboard, and a virtual keyboard. 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.

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

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 Web OS services such as 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. UI-related TV applications and Web applications based on the ENO framework are processed through the Luna-Service bus through Web OS core modules such as SAM, WAM, and LSM described above. 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 a wayland protocol, a luna-service call, 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, and input events. At this time, the LSM receives an event, focus, etc. from an input manager. Such an input manager may include a HID such as a remote controller, a mouse & keyboard, a joystick, a game pad, an application remote, and a pen touch.

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.) .

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

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 new types of pipelines 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 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 a pipeline 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 web OS boot . This is because the boot time of the 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. Also, the module may be capable of switching 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 may notify the audio data processing related data to the audio module 1150, which can perform the notification to the audio module 1150 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 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 DVR or channel related data to the DVR / channel manager based on the attribute or type of the TV service data received from the application, Create and process lines. 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 can transmit data or files that have passed through the TV broadcast handler to the TV pipeline manager based on the TV service policy, and can refer to the generated 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.

Hereinafter, various embodiments (s) for a method of processing audio data in a digital device according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 13 is a block diagram illustrating a configuration of a digital device according to an exemplary embodiment of the present invention. Referring to FIG. 13, a solid line arrow between each configuration module indicates an inter-process call, that is, a Luna service call, a notify such as register / notify, a data flow .

The application 1310 may be connected to various service processing configurations via a luna-service bus and may be operated or controlled through a connected service processing configuration.

The application 1310 includes audio data and may include an application 1311 related to the system sound, an application 1312 related to alert alerts, an application 1313 related to ringtones, An application 1314 related to notifications, an application 1315 related to media, an application 1316 related to TTS (Text to Speech), an application 1317 related to flash audio (Flash), and the like can do. However, this is merely an example, and fewer or more applications may be associated with the application 1310. [ It is also assumed that the digital device has implemented functions necessary for the operation of these applications.

The application 1311 related to the system sound refers to a sound selected by a specific key provided in the remote control devices 610, 620, and 630, a sound of a specific application output to the display unit of the digital device, And the like.

An application 1316 related to TTS (Text to Speech) is an application related to audio data for outputting a guidance message output through a display unit of a digital device by voice, and is mainly used when a voice recognition function is activated.

The application 1317 associated with flash audio (Flash) may be an application related to audio data streamed to Adobe Flash.

Depending on the user's selection or the occurrence of a specific event, the TV service processing unit 1330 or the pulse audio module 1340 can receive audio data from a specific application. For example, audio data to be processed through a decoder in hardware can be received at the TV service processing unit 1330, and PCM audio data that is already decoded audio data or does not need to be processed through a hardware decoder can be transmitted to a pulse audio module Lt; RTI ID = 0.0 > 1340 < / RTI > It can be controlled by the audio processing unit (AudioD) 1320 at which of the TV service processing unit 1330 or the pulse audio module 1340 the audio data from the specific application is to be received. The TV service processing unit 1330 may include a DASS (DSP Audio Sink Server) for hardware control of audio data. The pulse audio module 1340 may include an Advanced Linux Sound Architecture (ALSA), which is an interface for outputting audio data.

The TV service processing unit 1330 and the pulse audio module 1340 can notify the audio processing unit 1320 of audio data received from the application 1310. [ The audio processing unit 1320 may control the output of the audio data by controlling the TV service processing unit 1330 or the pulse audio module 1340 by applying a policy related to the audio data according to the notification.

The policy associated with the audio data is used to determine which type of audio data should be preferentially output based on the priority of each type of audio data when there is audio data corresponding to each of a plurality of contents, Control of the output volume level, and to which port of the audio output unit 1350 specific audio data is to be output. In the memory (not shown) in the digital device, a policy related to the audio data may be stored in advance. The audio processing unit 1320 controls the pulse audio module 1340 so that the audio data received from the application 1311 related to the system sound is outputted through the audio output unit 1350 without applying the policy You may.

The audio processing unit 1320 can adjust the input volume level and / or the output volume level of specific audio data. The audio processing unit 1320 may control an input volume level by controlling an input source of the volume level of specific audio data, may adjust the output volume level output through the audio output unit 1350 while maintaining the input level volume have.

The audio output unit 1350 may include a plurality of ports capable of outputting audio data in addition to a port 1351 connected to a TV speaker (internal speaker). For example, the audio output unit 1350 includes a port 1351 connected to a TV speaker, a port 1352 connected to an external speaker, a port 1353 connected to a headphone, an optical output port (SPDIF) 1354, A connected port 1355, and the like. The audio output unit 1350 outputs the audio data received from the TV service processing unit 1330 and / or the pulse audio module 1340.

Hereinafter, with reference to FIG. 14 to FIG. 21, examples of policies related to audio data applied in the audio processing unit 1320 will be described for each scenario.

14 is a diagram for explaining a method for activating a voice recognition function in a digital device according to an embodiment of the present invention. However, the method of activating the speech recognition function shown in FIG. 14 is merely an example, and the present invention is not limited thereto.
