Above the OS layer, a BSP (Board Support Package)/HAL (Hardware Abstraction Layer) layer, a Web OS core modules layer, a service layer, and a Luna-Service bus layer (Luna-Service) Bus layer), Nyo framework/NDK (Native Developer◎ Kit)/QT layer (Enyo framework/NDK/QT layer) and the application layer are sequentially present in the top layer.

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

The webOS core module layer is based on Luna Surface Manager (LSM) that manages surface windows, SAM (System & Application Manage) that manages execution and execution status of applications, and WebKit. It may include a Web Application Manager (WAM) for managing web applications.

The LSM manages an application window displayed on the screen. The LSM controls the display hardware (Display HW), provides a buffer for applications to render necessary content, and composites the results rendered by multiple applications on the screen. Can print

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

On the other hand, WAM, the web OS can view the web application (Web App) as a basic application, and is based on the Enyo Framework.

The service use of the application is performed through a Luna-service bus, and the service can be newly registered on the bus, and the application can also find and use the service it needs.

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

The WebOS service is a Linux process that implements function logic and can communicate over the bus. It can be largely divided into four parts, TV processes and services that are migrated to WebOS from existing TVs or services that are manufacturer differentiated services, webOS common services and JavaScript, and used through Node.js. It consists of Node.js service.

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

Applications on the web OS can be classified into a web application (Web Application), a Palm Development Kit (PDK) application, and a Qt Meta Language or Qt Modeling Language (QML) application depending on the implementation method.

The web application is based on a WebKit engine and is executed on the WAM runtime. The web application may be based on the ENYO framework, or developed and executed based on general HTML5, Cascading Style Sheets (CSS), and JavaScript.

The PDK application includes a native application developed in C/C++ based on a PDK provided for a third-party or external developer. The PDK refers to a set of development libraries and tools provided for third parties such as games to develop native applications (C/C++). For example, PDK applications can be used to develop applications where performance is important.

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

Meanwhile, in the above, the native application refers to an application developed and compiled in C/C++ and executed in a binary form, and such a native application has an advantage of fast execution speed.

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 a runtime of a web OS device, which can be understood by referring to the layered structure of FIG. 7.

Hereinafter, description will be given with reference to FIGS. 7 and 8.

Referring to FIG. 8, services and applications and WebOS core modules are included on a system OS (Linux) and system libraries, and communication between them may be performed through a Luna-service bus.

Node.js services based on HTML5, CSS, and JavaScript, including e-mail, contact, calendar, logging, backup, and file notify webOS services such as notify, database (DB), activity manager, system policy, audio daemon (AudioDmon), update, media server, etc., EPG TV services such as (Electronic Program Guide), PVR (Personal Video Recorder), data broadcasting, voice recognition, Now on, Notification, search CP services such as Auto Content Recognition (ARC), Contents List Broswer (CBOX), wfdd, DMR, Remote Application, Download, SDPIF (Sony Philips Digital Interface Format), PDK applications, browser , Native applications such as QML applications, and UI-related TV applications and web applications based on the Enyo framework are processed through web OS core modules such as SAM, WAM, and LSM described above through the Luna-service bus. Meanwhile, in the above, TV applications and web applications may not necessarily be based on the Enyo framework or UI.

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

The SAM is intended to improve module complexity and improve scalability. For example, the existing system manager handles several functions such as system UI, window management, web application runtime, and constraint processing on UX in a single process. By clarifying the inter-interface, the implementation complexity is reduced.

LSM supports system UX implementation such as card view and launcher to be independently developed and integrated, and supports to easily respond to changes in product requirements. On the other hand, LSM, in the case of compositing multiple application screens such as app-on-apps, makes full use of hardware resources (HW resource) to enable multi-tasking, such as multi-window (multi-window) and 21:9. It can provide a window management mechanism (window management mechanism) for.

LSM supports the implementation of system UI based on QML, and improves the development productivity. QML UX is based on MVC, so it is easy to construct views for screen layout and UI components, and it is also easy to develop code for processing user input. On the other hand, the interface between the QML and the webOS component is done through 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, and functions as an application window compositor.

LSM composes and outputs independently developed applications and UI components on the screen. In relation, when components such as a Recents application, a showcase application, and a launcher application respectively render their own contents, the LSM defines an output area, an interworking method, etc. as a compositor. In other words, the compositor LSM handles graphic composition, focus management, and input events. At this time, the LSM receives events, focus, and the like from the input manager. Such input managers may include a remote controller, HID such as a mouse & keyboard, joystick, game pad, application remote, pen touch, and the like.

As such, the LSM supports multiple window models, which can be executed simultaneously in all applications due to the system UI characteristics. In relation, Launcher, Recents, Settings, Notification, System Keyboard, Volume UI, Search, Finger gesture, Voice Recognition (STT (Sound to Text), TTS (Text to) LSM can support Sound), NLP (Natural Language Processing), etc., 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.

Referring to FIG. 9, the graphic composition processing includes a web application manager 910 in charge of a UI process, a webkit 920 in charge of a web process, a LSM 930 and a graphic manager (GM) 940.

When the web application-based graphic data (or application) is generated as a UI process in the web application manager 910, if the generated graphic data is not a full-screen application, it is transferred to the LSM 930. On the other hand, the web application manager 910 receives the application generated by the web kit 920 to share the graphic processing unit (GPU) memory for graphic management between the UI process and the web process, and this is a full-screen as described above. If it is not an application, it is delivered to the LSM 930. In the case of the full-screen application, the LSM 930 may be bypassed, and in this case, it may be directly transferred to the graphic manager 940.

The LSM 930 transmits the received UI application via the Wayland surface to the Wayland Compositor, and processes it appropriately in the Wayland Compositor and delivers it to the graphic manager. The graphic data transmitted from the LSM 930 is transmitted to the graphic manager compositor through the LSM GM surface of the graphic manager 940, for example.

Meanwhile, as described above, the full-screen application is delivered directly to the graphic manager 940 without going through the LSM 930, which is processed by the graphic manager compositor through the WAM GM surface.

The graphic manager processes all graphic data in the webOS device, such as the data through the LSM GM surface described above, the data through the WAM GM surface, as well as the GM surface, such as a data broadcasting application and a caption application. All graphic data passed through is received and processed to be properly displayed on the screen. Here, the function of the GM compositor is the same or similar function to the compositor described above.

10 is a view illustrating a media server according to an embodiment of the present invention, and FIG. 11 is a diagram illustrating 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 necessary resources. The media server can efficiently use hardware resources required for media play. For example, the media server requires audio/video hardware resources to execute multimedia, and can efficiently utilize the resource usage status. In general, a fixed device having a larger screen than a mobile device requires more hardware resources when executing multimedia, and the encoding/decoding and graphic data transfer speeds need to be fast due to a large amount of data. Meanwhile, in addition to streaming and file-based playback, the media server performs broadcasting, recording, and tuning tasks, recording simultaneously with viewing, or simultaneously displaying a sender and a receiver screen during a video call. It should be able to handle the back. However, in the media server, hardware resources such as an encoder, a decoder, a tuner, and a display engine are limited on a chip-set basis, making it difficult to execute multiple tasks at the same time. Process the input.

The media server can enhance system stability, for example, by removing and restarting a playback pipeline for which an error occurred during media playback for each pipeline, and thus generating an error as described above. This may not affect other media play. This pipeline is a chain that connects each unit functions such as decoding, analysis, and output when requesting media playback, and required unit functions may be changed according to a media type.

The media server can have extensibility, for example, a new type of pipeline can be added without affecting the existing implementation. For 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 normal media playback and TV task execution as separate services because the interface of the TV service is different from the media playback case. In the above, the media server supports operations such as setchannel, channelup, channeldown, channeltuning, recordstart, etc. in relation to TV service, and supports operations such as play, pause, stop, etc. in relation to general media playback, and is different for both. It supports operations and can be processed as a separate service.

The media server can control or integrate resource management functions. The hardware resource allocation and retrieval in the device are integrated in the media server, and in particular, the TV service process delivers the running task and resource allocation status to the media server. The media server secures resources each time each media is executed and the pipeline is executed. Based on the resource status occupied by each pipeline, the media server allows execution by priority (for example, policy) when requesting media execution and Resource recovery of other pipelines is performed. Here, the predefined execution priority and required resource information for a specific request are managed by a policy manager, and the resource manager communicates with the policy manager to process resource allocation, recovery, and the like.

The media server may have an identifier (ID) for all operations related to playback. For example, the media server may issue a command by instructing a specific pipeline based on the identifier. The media server may issue commands to the pipelines by dividing the two into two or more media.

The media server can be responsible for playing HTML 5 standard media.

In addition, the media server can follow the TV restructuring scope for the separate service process of the TV pipeline. The media server may be designed and implemented regardless of the TV restructuring range. If the TV is not serviced separately, the entire TV may need to be re-run when a problem occurs in a specific task.

The media server is also called a uMS, that is, a micro media server. Here, the media player is a media client, which is, for example, the web for HTML5 video tags, cameras, TVs, Skype, second screens, and the like. It can mean a kit (Webkit).

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

The media server supports, for example, extensibility, reliability, and efficient resource usage.

In other words, uMS, that is, the media server, is a cloud game (cloud game), MVPD (pay service, etc.), camera preview (camera preview), second screen (2nd screen), skyOS, and other resources such as web OS devices such as TV resources It manages and controls the use of resources for proper processing in general, and functions to manage and control for efficient use. Meanwhile, each resource uses a pipeline, for example, when used, and the media server can overall manage and control the creation, deletion, and use of the pipeline for resource management.

Here, a pipeline is generated when, for example, a media related to a task starts continuation of operations such as request, decoding stream, and video output. Can be. For example, in relation to a TV service or application, watching, recording, channel tuning, etc. are individually handled under control of resource usage through a pipeline generated according to the request. .

Referring to FIG. 10, the processing structure of the media server and the like will be described in more detail as follows.

In FIG. 10, an application or service is connected to a media server 1020 and a Luna-service bus 1010, and the media server 1020 communicates with pipelines regenerated through the Luna-service bus 1010. Connected and managed.

The application or service has various clients according to its characteristics, and through which data can be exchanged with the media server 1020 or the pipeline.

The client includes, for example, a uMedia client (web kit) and a resource manager (RM) client (C/C++) for connecting 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 the video by request or the like.

Here, the video operation relates to a video state, and loading, unloading, play, playback, reproduce, pause, stop, etc. are all states related to the video operation. Data. Each operation or state of this video can be processed through individual pipeline creation. Accordingly, the uMedia client transmits state data related to the video operation to the pipeline manager 1022 in the media server.

The pipeline manager 1022 acquires information about a resource of the current device through data communication with the resource manager 1024 and requests allocation of a resource corresponding to the status data of the uMedia client. At this time, the pipeline manager 1022 or the resource manager 1024 controls the resource allocation through data communication with the policy manager 1026 when necessary. For example, when the resource manager 1024 has no or insufficient resources to allocate at the request of the pipeline manager 1022, appropriate resource allocation or the like is made according to the request according to the priority comparison of the policy manager 1026 or the like. Can.

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

The media pipeline controller 1028 creates a necessary pipeline under the control of the pipeline manager 1022. As shown in the pipeline, the media pipeline and the camera pipeline, as well as pipelines related to playback, pause, pause, etc. may be created in the pipeline. Meanwhile, the pipeline may include a pipeline for HTML5, web CP, smartshare playback, thumbnail extraction, NDK, cinema, Multimedia and Hypermedia Information coding Experts Group (MHEG), and the like.

In addition, the pipeline may include, for example, a service-based pipeline (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 handle the media. In other words, when an application or service directly processes media, it may not go through a media server. However, at this time, resource management is required for pipeline creation and its use. For this, the uMS connector functions. Meanwhile, when a resource management request for direct media processing of the application or service is received, the uMS connector communicates with the media server 1020 including the resource manager 1024. To this end, the media server 1020 should also be provided with a uMS connector.

Accordingly, an application or service may respond to a request of an RM client by receiving 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 medium source extensions (MSE), cloud games, and Skype. In this case, as described above, the resource manager 1024 may manage resources through data communication with the policy manager 1026 when necessary for resource management.

On the other hand, the URI-based pipeline is made through the media server 1020, not in the case of directly processing media like the RM client described above. The URI-based pipeline may include a player factory, a Gstreamer, a streaming plug-in, and a digital rights management (DRM) plug-in pipeline.

Meanwhile, an interface method between an application and media services may be as follows.

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

And, it is a method of interfacing using services in PDK.

Or, it is a method of using the service in the existing CP. This can be used by extending the plug-in of the existing platform based on Luna for backward compatibility.

Finally, in the case of non-webOS, it is a way to interface. In this case, the Luna bus can be called directly to interface.

The seamless change is processed by a separate module (for example, TVWIN), which is a process for displaying and displaying the TV on the screen without webOS first and seamlessly, before or during booting of the webOS. . This is used for the purpose of first providing the basic function of the TV service for quick response to a user's Power On request because the booting time of the WebOS is late. In addition, the module supports a firmware change, factory mode, etc. that provide fast booting and basic TV functions as part of the TV service process. In addition, the module may be in charge of switching from Non-WebOS mode to WebOS mode.

11, the processing structure of the media server is illustrated.

In this case, in FIG. 11, the solid line box indicates a process processing configuration, and the dotted line box indicates an internal processing module during the process. In addition, a solid arrow indicates an inter-process call, that is, a Luna service call, and a dotted arrow indicates a notification or data flow such as register/notify.

The service or web application or PDK application (hereinafter referred to as an application) is connected to various service processing components through a Luna-service bus, through which the application operates or is controlled.

The data processing path varies depending on the type of application. For example, when the application is image data related to a camera sensor, it is transmitted to the camera processor 1130 for processing. At this time, the camera processor 1130 processes image data of the received application, including a gesture, a face detection module, and the like. Here, the camera processing unit 1130 may process the data by creating a pipeline through the media server processing unit 1110, for example, in the case of data that is required by the user or automatically using a pipeline.

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

Alternatively, when the application includes or processes (hereinafter included) DRM-hung content, the corresponding content data is transmitted to the DRM service processing unit 1160, and the DRM service processing unit 1170 creates a DRM instance. To process DRM-hung content data. Meanwhile, the DRM service processing unit 1160 may be connected to and process the DRM pipeline in the media pipeline through the Luna-service bus for processing of the DRM-hung content data.

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

FIG. 12 is a view for explaining in more detail only the media server processing unit and the TV service processing unit in FIG. 11 described above.

Therefore, hereinafter, it will be described with reference to Figures 11 and 12 together.

First, when the application includes TV service data, it is processed by the TV service processor 1120/1220.

Here, the TV service processing unit 1120 includes, for example, 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 configuration module, and a route manager. Alternatively, the TV service processing unit 1220 in FIG. 12 includes a TV broadcast handler, a TV broadcast interface, a service processing unit, a TV middleware (TV middleware), a route manager, and a BSP ( For example, NetCast). Here, the service processing unit may mean, for example, a module including a TV pipeline manager, a TV resource manager, a TV policy manager, and a USM connector.

In the present specification, the TV service processing unit may have a configuration as illustrated in FIG. 11 or 12 or may be implemented in a combination of both, and some components may be omitted or some components not shown may be added.

The TV service processing unit 1120/1220 transmits to the DVR/channel manager in case of digital video recorder (DVR) or channel-related data based on the attribute or type of TV service data received from the application, and then back to the TV pipeline manager To the TV pipeline and process it. On the other hand, when the attribute or type of the TV service data is broadcast content data, the TV service processor 1120 generates and processes the TV pipeline through the TV pipeline manager to process the data through the broadcast module.

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

Meanwhile, the TV pipeline manager may be under the control of the TV resource manager in creating one or more pipelines according to a TV pipeline generation request from a processing module or a manager in the TV service. Meanwhile, the TV resource manager may be under the control of the TV policy manager to request the status and allocation of resources allocated for the TV service according to the TV pipeline manager's request to create a TV pipeline, and the media server processor 1110 /1210) and uMS connector. The resource manager in the media server processing unit 1110/1210 transmits the status and allocation of resources for the current TV service at the request of the TV resource manager. For example, as a result of checking the resource manager in the media server processing unit 1110/1210, if all the resources for the TV service have already been allocated, the TV resource manager may notify that all resources are currently allocated. At this time, the resource manager in the media server processing unit, along with the notify, removes a predetermined TV pipeline according to a priority or a predetermined criterion among TV pipelines allocated for a TV service, and the TV pipeline for the requested TV service. You can also request or allocate creation. Alternatively, the TV resource manager may appropriately remove, add, or establish a 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 backward compatibility with, for example, existing digital devices.

The TV pipelines thus generated can be properly operated under the control of the route manager in the process. The route manager may determine or control the processing route or process of the pipelines in consideration of the operation of the pipeline generated by the media server processor 1110/1210 as well as the TV pipeline in the process.

Next, when the application includes media data rather than TV service data, the media server processing unit 1110/1210 processes it. Here, the media server processing unit 1110/1210 includes a resource manager, a policy manager, a media pipeline manager, a media pipeline controller, and the like. Meanwhile, the pipeline created under 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. Meanwhile, the media pipeline may include a streaming protocol, an auto/static gstreamer, DRM, etc., and the processing flow may be determined according to the control of the route manager. The detailed processing process in the media server processing unit 1110/1210 uses the description of FIG. 10 described above, and is not described herein again.

In the present specification, the resource manager in the media server processor 1110/1210 may manage resources on a counter basis, for example.

13 is a diagram illustrating a control method of a remote control device that controls any one of video display devices according to embodiments of the present invention.

As illustrated in FIG. 13A, a pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180.

The user can move or rotate the remote control device 200 up, down, left and right (FIG. 13 (b)), and back and forth (FIG. 13 (c)). The pointer 205 displayed on the display unit 180 of the image display device corresponds to the movement of the remote control device 200. The remote control device 200 may be referred to as a spatial remote controller, as the corresponding pointer 205 is moved and displayed according to the movement on the 3D space, as shown in the drawing.

13B illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display unit 180 of the image display device moves to the left correspondingly.

The video display device may calculate the coordinates of the pointer 205 from information on the movement of the remote control device 200. The image display device may display the pointer 205 to correspond to the calculated coordinates.

13C illustrates a case in which a user moves the remote control device 200 away from the display unit 180 while pressing a specific button in the remote control device 200. Accordingly, the selected area in the display unit 180 corresponding to the pointer 205 may be zoomed in to be enlarged and displayed. Conversely, when the user moves the remote control device 200 to be closer to the display unit 180, the selected area in the display unit 180 corresponding to the pointer 205 may be zoomed out and reduced. On the other hand, when the remote control device 200 moves away from the display unit 180, the selection area is zoomed out, and when the remote control device 200 approaches the display unit 180, the selection area may be zoomed in.

Meanwhile, in a state in which a specific button in the remote control device 200 is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device 200 moves to move away from or approach the display unit 180, the up, down, left, and right movements are not recognized, and only the forward and backward movements can be recognized. When a specific button in the remote control device 200 is not pressed, only the pointer 205 moves according to the up, down, left, and right movements of the remote control device 200.

Meanwhile, the moving speed or the moving direction of the pointer 205 may correspond to the moving speed or the moving direction of the remote control device 200.

Meanwhile, the pointer in the present specification means an object displayed on the display unit 180 in response to the operation of the remote control device 200. Accordingly, various shapes of objects other than the arrow shape illustrated in the drawing are possible with the pointer 205. For example, it may be a concept including points, cursors, prompts, and thick outlines. In addition, the pointer 205 may be displayed corresponding to any one point of the horizontal axis and the vertical axis on the display unit 180, as well as a plurality of points such as a line and a surface. Do.
