The microphone 322 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.
The user input unit 330 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, and a jog switch.
The sensing unit 340 provides sensing signals for controlling operations of the mobile terminal 300 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 340 may detect an open/closed status of the mobile terminal 100, the relative positioning of components (e.g., a display and keypad) of the mobile terminal 300, a change of position (or location) of the mobile terminal 300 or a component of the mobile terminal 300, a presence or absence of user contact with the mobile terminal 300, and an orientation or acceleration/deceleration of the mobile terminal 300. As an example, a mobile terminal 300 configured as a slide-type mobile terminal is considered. In this configuration, the sensing unit 340 may sense whether a sliding portion of the mobile terminal is open or closed. According to other examples, the sensing unit 340 senses the presence or absence of power provided by the power supply unit 390, and the presence or absence of a coupling or other connection between the interface unit 370 and an external device. According to one embodiment, the sensing unit 340 can include a proximity sensor 341.

A representative example of the transparent display is the TOLED (transparent OLED). A rear configuration of the display 351 can be implemented as the optical transmittive type as well. In this configuration, a user may be able to see an object located at the rear of a terminal body on a portion of the display 351 of the terminal body.
At least two displays 351 can be provided in the mobile terminal 300 in accordance with one embodiment of the mobile terminal 300. For instance, a plurality of displays can be arranged to be spaced apart from each other or to form a single body on a single face of the mobile terminal 300. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 300.
If the display 351 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) are configured as a mutual layer structure (hereinafter called ‘touch screen’), the display 351 is usable as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, or a touchpad.
The touch sensor can be configured to convert pressure applied to a specific portion of the display 351 or a variation of capacitance generated from a specific portion of the display 351 to an electronic input signal. Moreover, the touch sensor is configurable to detect pressure of a touch as well as a touched position or size.
If a touch input is made to the touch sensor, a signal(s) corresponding to the touch input is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 380. Therefore, the controller 380 is made aware when a prescribed portion of the display 351 is touched.
Referring to
The proximity sensor 341 can include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. If the touch screen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of an electric field according to the proximity of the pointer. In this configuration, the touch screen (touch sensor) can be considered as the proximity sensor.
For clarity and convenience of explanation, an action for enabling the pointer approaching the touch screen to be recognized as placed on the touch screen may be named ‘proximity touch’ and an action of enabling the pointer to actually come into contact with the touch screen may named ‘contact touch’. And, a position, at which the proximity touch is made to the touch screen using the pointer, may mean a position of the pointer vertically corresponding to the touch screen when the pointer makes the proximity touch.
The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state). Information corresponding to the detected proximity touch action and the detected proximity touch pattern can be output to the touch screen.
The audio output module 352 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, and a broadcast reception mode to output audio data which is received from the wireless communication unit 310 or is stored in the memory 360.

The alarm unit 353 is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be output via the display 351 or the audio output module 352. Hence, the display 351 or the audio output module 352 can be regarded as a part of the alarm unit 353.
The haptic module 354 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 354. The strength and pattern of the vibration generated by the haptic module 354 are controllable. For instance, different vibrations can be output in a manner of being synthesized together or can be output in sequence. The haptic module 354 is able to generate various tactile effects as well as the vibration. For instance, the haptic module 354 may generate an effect attributed to the arrangement of pins vertically moving against a contact skin surface, an effect attributed to the injection/suction power of air though an injection/suction hole, an effect attributed to the skim over a skin surface, an effect attributed to a contact with an electrode, an effect attributed to an electrostatic force, and an effect attributed to the representation of a hot/cold sense using an endothermic or exothermic device. The haptic module 354 can be implemented to enable a user to sense the tactile effect through a muscle sense of a finger or an arm as well as to transfer the tactile effect through direct contact. Optionally, at least two haptic modules 354 can be provided in the mobile terminal 300 in accordance with an embodiment of the mobile terminal 300.

A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectible to the mobile terminal 300 via the corresponding port.
When the mobile terminal 300 is connected to an external cradle, the interface unit 370 becomes a passage for supplying the mobile terminal 300 with a power from the cradle or a passage for delivering various command signals input from the cradle by a user to the mobile terminal 300. Each of the various command signals input from the cradle or the power can operate as a signal enabling the mobile terminal 300 to recognize that it is correctly loaded in the cradle.
The controller 380 typically controls the overall operations of the mobile terminal 300. For example, the controller 380 performs the control and processing associated with voice calls, data communications, and video calls. The controller 380 may include a multimedia module 381 that provides multimedia playback. The multimedia module 381 may be configured as part of the controller 380, or implemented as a separate component.
Moreover, the controller 380 is able to perform a pattern (or image) recognizing process for recognizing a writing input and a picture drawing input carried out on the touch screen as characters or images, respectively.
The power supply unit 390 provides power required by various components of the mobile terminal 300. The power may be internal power, external power, or combinations of internal and external power.

Also, the tuner 410 may convert the received RF broadcast signal to an IF (Intermediate Frequency) signal or a baseband signal.
For example, if the received RF broadcast signal is a digital broadcast signal, the RF broadcast signal is converted to the IF (Intermediate Frequency) signal. Also, if the received RF broadcast signal is an analog broadcast signal, the RF broadcast signal is converted to an analog baseband video or audio signal (CVBS/SIF).

The digital device 400 may a digital broadcast receiver for processing a digital broadcast signal of ATSC type or DVB type.
Also, in the digital device 400, some of the components may be omitted or a component may be added as required. The digital receiver according to the present invention may not include the tuner and the demodulator, differently from the digital receivers shown in
The digital receiver according to the present invention may include a demultiplexer 510, an image processor 520, an OSD generator 540, a mixer 550, a frame rate converter (FRC) 555, and a 3D formatter (or an Output formatter) 560.
The demultiplexer 510 can demultiplex an input stream signal into an MPEG-2 TS image, an audio signal and a data signal, for example.
The image processor 420 can process a demultiplexed image signal using a video decoder 525 and a scaler 535.
The video decoder 525 can decode the demultiplexed image signal and the scaler 535 can scale the resolution of the decoded image signal such that the image signal can be displayed.
The video decoder 525 can support various standards.
The image signal decoded by the image processor 520 may be input to the mixer 550.
The OSD generator 540 may generate OSD data automatically or according to user input. For example, the OSD generator 540 may generate data to be displayed on the screen of an output unit in the form of an image or text on the basis of a control signal of a user input interface. OSD data generated by the OSD generator 540 may include various data such as a user interface image of the digital receiver, various menu screens, widget, icons, and information on ratings. The OSD generator 540 can generate a caption of a broadcast image or data for displaying EPG based broadcast information.
The mixer 550 may mix the OSD data generated by the OSD generator 540 and the image signal processed by the image processor 520. The mixer 550 may provide the mixed signal to the 3D formatter 560. By mixing the decoded image signal and the OSD data, OSD may be overlaid on a broadcast image or external input image.
The frame rate converter (FRC) 555 may convert a frame rate of input video. For example, the frame rate converter 555 can convert the frame rate of an input 60 Hz video to a frame rate of 120 Hz or 240 Hz, according to an output frequency of the output unit. The frame rate converter 555 may be bypassed when frame conversion is not executed.
The 3D formatter 560 may change the output of the frame rate converter 555, which is input thereto, into a form suitable for the output format of the output unit. For example, the 3D formatter 560 can output an RGB data signal. In this case, this RGB data signal can be output according to low voltage differential signaling (LVDS) or mini-LVDS. When a 3D image signal output from the frame rate converter 555 is input to the 3D formatter 560, the 3D formatter 560 can format the 3D image signal such that the 3D image signal is matched to the output format of the output unit, to thereby support a 3D service.
An audio processor (not shown) may audio-process a demultiplexed audio signal. The audio processor (not shown) can support various audio formats. For example, when audio signals are encoded in MPEG-2, MPEG-4, advanced audio coding (AAC), high efficiency-AAC (HE-AAC), AC-3 and bit sliced audio coding (BSAC) formats, the audio processor (not shown) can include decoders corresponding to the formats to process the audio signals.
Furthermore, the audio processor (not shown) can control base, treble and volume.
In addition, a data processor (not shown) can process a demultiplexed data signal. For example, when a demultiplexed data signal is encoded, the data processor (not shown) can decode the encoded demultiplexed data signal. Here, the encoded data signal may be EPG information including broadcast information such as the start time and end time (or duration) of a broadcast program which is broadcast through each channel.

The digital device described in the present specification can be operated by based on WebOS platform. Hereinafter, a WebOS based process or algorithm may be performed by the controller of the above-described digital device. The controller includes the controllers of
Such a WebOS based platform may improve development independency and functional extensibility by integrating services, applications, etc. based on a Luna-service bus, for example, and increase application development productivity based on web application framework. In addition, system resources, etc. may be efficiently used via a WebOS process and resource management to support multitasking.
A WebOS platform described in the present specification may be available or loaded not only for stationary devices such as personal computers (PCs), TVs and set top boxes (STBs) but also for mobile devices such as cellular phones, smartphones tablet PCs, laptops, and wearable devices.
A software structure for a digital device is a monolithic structure which solves conventional problems depending on markets, is a single process and closed product based on multi-threading, and has difficulties in terms of external applications. In pursuit of new platform based development, cost innovation via chipset replacement and UI application and external application development efficiency, layering and componentization are performed to obtain a 3-layered structure and an add-on structure for an add-on, a single source product and an open application. Recently, modular design of a software structure has been conducted in order to provide a web open application programming interface (API) for an echo system and modular architecture of a functional unit or a native open API for a game engine, and thus a multi-process structure based on a service structure has been produced.
The architecture of a WebOS platform will now be described with reference to
The platform may be largely divided into a kernel, a webOS core platform based on a system library, an application, a service, etc.
The architecture of the WebOS platform has a layered structure. OS is provided at a lowest layer, system library(s) are provided at a next highest layer and applications are provided at the highest layer.
First, the lowest layer is an OS layer including a Linux kernel such that Linux is included as an OS of the digital device.
At layers higher than the OS layer, a board support package (BSP)/hardware abstraction layer (HAL) layer, a WebOS core modules layer, a service layer, a Luna-service bus layer and an Enyo framework/native developer's kit (NDK)/QT layer are sequentially provided. At the highest layer, an application layer is provided.
One or more layers of the above-described WebOS layered structure may be omitted and a plurality of layers may be combined to one layer and one layer may be divided into a plurality of layers.
The WebOS core module layer may include a Luna surface manager (LSM) for managing a surface window, etc., a system & application manager (SAM) for managing execution and performance status of applications, etc., and a web application manager (WAM) for managing web applications based on WebKit.
The LSM manages an application window displayed on a screen. The LSM may control display hardware (HW) and provide a buffer for rendering content necessary for applications, and compose and output results of rendering a plurality of applications on a screen.
The SAM manages policy according to several conditions of systems and applications.
The WAM is based on Enyo framework, because a WebOS regards a web application as a basic application.
An application may use a service via a Luna-service bus. A service may be newly registered via a bus and the application may detect and use a desired service.
The service layer may include services having various service levels, such as a TV service, a WebOS service, etc. The WebOS service may include a media server, Node.JS, etc. and, in particular, the Node.JS service supports JavaScript, for example.
The WebOS service may be communicated to a Linux process implementing function logic via a bus. This WebOS service is largely divided into four parts, migrates from a TV process and an existing TV to a WebOS, is developed as services which differ between manufacturers, WebOS common services and Javascripts, and is composed of the Node.JS service used via Node.JS.
The application layer may include all applications supportable by a digital device, such as a TV application, a showcase application, a native application, a web application, etc.
Applications on the WebOS may be divided into a web application, a palm development kit (PDK) application, a Qt Meta Language or Qt Modeling Language (QML) application, etc. according to implementation methods.
The web application is based on a WebKit engine and is performed on WAM runtime. Such a web application is based on Enyo framework or may be developed and performed based on general HTML5, cascading style sheets (CSS) and JavaScripts.
The PDK application includes a native application developed with C/C++ based on a PDK provided for a third party or an external developer. The PDK refers to a set of development libraries and tools provided to enable a third party to develop a native application (C/C++) such as games. For example, the PDK application may be used to develop applications requiring high performance.
The QML application is a native application based on Qt and includes basic applications provided along with the WebOS platform, such as card view, home dashboard, virtual keyboard, etc. QML is a markup language of a script format, not C++.
The native application is an application which is developed and compiled using C/C++ and is executed in the binary form and has an advantage such as high execution speed.
Hereinafter, a description will be given with reference to
Referring to
Node.JS services based on HTML5 such as e-mail, contact or calendar, CSS, Javascript, etc., WebOS services such as logging, backup, file notify, database (DB), activity manager, system policy, audio daemon (AudioD), update, media server, etc., TV services such as electronic program guide (EPG), personal video recorder (PVR), data broadcasting, etc., CP services such as voice recognition, Now on, notification, search, auto content recognition (ACR), contents list browser (CBOX), wfdd, digital media remastering (DMR), remote application, download, Sony Philips digital interface format (SDPIF), etc., native applications such as PDK applications, browsers, QML applications, a UI-related TV applications based on Enyo framework and web applications are processed via WebOS core modules such as the above-described SAM, WAM and LSM via the Luna-service bus. The TV applications and the web applications are not necessarily based on Enyo framework or related to UI.
The CBOX may manage metadata and lists of content of external devices such as USB drivers, DLNA devices or Cloud servers connected to a TV. The CBOX may output content listing of various content containers such as USB, data management system (DMS), DVR, Cloud server, etc. as an integrated view. The CBOX may display various types of content listings such as pictures, music or video and manage metadata thereof. The CBOX may output content of an attached storage in real time. For example, if a storage device such as a USB is plugged in, the CBOX should immediately output a content list of the storage device. At this time, a standardized method for processing the content listing may be defined. The CBOX may accommodate various connection protocols.
The SAM is used to improve module complexity and extensibility. For example, an existing system manager processes several functions such as system UI, window management, web application runtime and UX constraint processing via one process and thus has high implementation complexity. In order to solve such a problem, the SAM divides main functions and clarifies an interface between functions, thereby decreasing implementation complexity.
The LSM is supported to independently develop and integrate a system UX such as card view, launcher, etc. and to easily cope with change in product requirements. The LSM maximally uses hardware resources to enable multitasking if a plurality of application screens is composed using an app-on-app method and may provide a window management mechanism for 21:9 and a multi-window.
The LSM supports implementation of a system UI based on a QML and improves development productivity. QML UX may easily configure a view using a screen layout and UI components based on model view controller (MVC) and easily develop code for processing user input. An interface between the QML and the WebOS component is achieved via a QML extensibility plug-in and graphic operation of an application may be based on Wayland protocol, luna-service call, etc.
The LSM is an abbreviation for a Luna surface manager and functions as an application window compositor.
The LSM composes and outputs independently developed applications, UI components, etc. on a screen. When components such as recent applications, showcase applications or launcher applications render respective content, the LSM defines an output area, a linkage method, etc. as a compositor. The LSM functioning as a compositor performs processing such as graphic composition, focus management, input events, etc. At this time, the LSM receives event, focus, etc. from an input manager, and a remote controller, a HID such as a mouse and keyboard, a joystick, a game pad, a remote application, a pen touch, etc. may be included as an input manager.
The LSM supports multiple window models and may be simultaneously executed in all applications as a system UI. The LSM may support launcher, recents, setting, notification, system keyboard, volume UI, search, finger gesture, voice recognition (speech to text (STT), text to speech (TTS), natural language processing (NLP), etc.), pattern gesture (camera or mobile radio control unit (MRCU)), live menu, ACR, etc.
Referring to
When the web application manager 910 generates web application based graphics data (or application) as a UI process, the generated graphics data is delivered to the LSM if the graphics data is not a fullscreen application. The web application manager 910 receives an application generated by the WebKit 920 in order to share a graphic processing unit (GPU) memory for graphic management between the UI process and the web process and delivers the application to the LSM 930 if the application is not a fullscreen application. If the application is a fullscreen application, the LSM 930 may bypass the application. In this case, the application is directly delivered to the graphics manager 940.
The LSM 930 transmits the received UI application to a Wayland compositor via a Wayland surface and the Wayland compositor appropriately processes the UI application and delivers the processed UI application to the graphics manager. The graphics data received from the LSM 930 is delivered to the graphics manager compositor via the LSM GM surface of the graphics manager 940, for example.
The fullscreen application is directly delivered to the graphics manager 940 without passing through the LSM 930 as described above and is processed in the graphics manager compositor via the WAM GM surface.
The graphics manager processes and outputs all graphics data in the webOS device and receives and outputs data passing through the above-described LSM GM surface, data passing through a WAM GM surface, and graphics data passing through a GM surface, such as a data broadcasting application or a caption application, on a screen. The function of the GM compositor is equal or similar to the above-described compositor.
The media server supports execution of a variety of multimedia in a digital device and manages necessary resources. The media server may efficiently use hardware resources necessary for media play. For example, the media server requires audio/video hardware resources for multimedia execution and efficiently manages a resource use status to efficiently use resources. In general, a stationary device having a screen larger than that of a mobile device requires more hardware resources upon multimedia execution and requires high encoding/decoding rate and graphics data transfer rate due to a large amount of data. The media server should perform not only streaming or file playback but also broadcasting, recording and tuning tasks, a task for simultaneously viewing and recording, and a task for simultaneous displaying a sender and a recipient on a screen upon video call. It is difficult for the media server to simultaneously perform several tasks due to restriction in hardware resources such as an encoder, a decoder, a tuner, a display engine, etc. in chipset units. For example, the media server restricts a use scenario or performs processing using user input.
The media server may make system stability robust, and may remove a playback pipeline, in which errors occur during media playback, per pipeline, such that other media play is not influenced even when errors occur. Such a pipeline is a chain for connecting unit functions such as decoding, analysis, output, etc. upon a media playback request, and required unit functions may be changed according to media type, etc.
The media server may have extensibility and may add a new type of pipeline without influencing an existing implementation method. For example, the media server may accommodate a camera pipeline, a video conference (Skype) pipeline, a third-party pipeline, etc.
The media server may process general media playback and TV task execution as separate services because the interface of the TV service is different from that of media playback. The media server supports operation such as “setchannel”, “channelup”, “channeldown”, “channeltuning” and “recordstart” in relation to the TV service and support operation such as “play”, “pause” and “stop” in relation to general media playback, that is, supports different operations with respect to the TV service and general media playback and processes the TV service and media playback as separate services.
The media server may control or manage a resource management function. Hardware resource assignment or recovery in a device is conducted by the media server. In particular, the TV service process delivers a task which is being executed and a resource assignment status to the media server. The media server secures resources to execute a pipeline whenever media is executed, allows media execution due to priority (e.g., policy) upon media execution request, and performs resource recovery of another pipeline, based on a resource status of each pipeline. The predefined execution priority and resource information necessary for a specific request are managed by a policy manager and the resource manager communicates with the policy manager to process resource assignment and recovery.
The media server may have identifiers (IDs) for all operations related to playback. For example, the media server may send a command to a specific pipeline based on the ID. The media server may send respective commands to pipelines for playback of two or more media.
The media server is responsible for playing back a HTML5 standard media.
The media server performs a service process of a TV pipeline according to a TV restructuralization range. The media server may be designed and implemented regardless of the TV restructuralization range. If the separate service process of the TV is not performed, the TV may be wholly re-executed when errors occurs in a specific task.
The media server is also referred to as uMS, that is, a micro media server. The media player is a media client and means WebKit for HTML5 video tag, camera, TV, Skype or second screen, for example.
The media server mainly manages micro resources such as a resource manager or a policy manager. The media server also controls playback of web standard media content. The media server may manage pipeline controller resources.
The media server supports extensibility, reliability, efficient resource usage, etc., for example.
In other words, the uMS, that is, the micro media server, manages and controls resource usage for appropriate processing within the WebOS device, such as resources such as cloud game, MVPD (pay service, etc.), camera preview, second screen or Skype, and TV resources. A pipeline is used upon usage of each resource, for example, and the media server may manage and control generation, deletion, use of a pipeline for resource management.
The pipeline may be generated when a media related to a task starts a sequence of request, decoding streaming and parsing such as video output. For example, in association with a TV service and an application, watching, recording, channel tuning, etc. are controlled and performed via pipelines individually generated according to requests thereof with respect to resource usage.
Referring to
In
The application or service includes various clients according to properties thereof and may exchange data with the media server 1020 or the pipeline via the clients.
The clients include a uMedia client (WebKit) for connection with the media server 1020 and a resource manager (RM) client (C/C++), for example.
The application including the uMedia client is connected to the media server 1020 as described above. More specifically, the uMedia client corresponds to the below-described video object, for example, and uses the media server 1020, for video operation by a request, etc.
The video operation relates to a video status and may include all status data related to the video operation, such as loading, unloading, play (playback or reproduction), pause, stop, etc. Such video operations or statuses may be processed by generating individual pipelines. Accordingly, the uMedia client transmits status data related to the video operation to the pipeline manager 1022 in the media server.
The media server 1022 acquires information about resources of the current device via data communication with the resource manager 1024 and requests assignment of resources corresponding to the status data of the uMedia client. At this time, the pipeline manager 1022 or the resource manager 1024 controls resource assignment via data communication with the policy manager 1026 if necessary. For example, if resources to be assigned according to the request of the pipeline manager 1022 are not present or are lacking in the resource manager 1024, resource assignment may be appropriately performed according to priority comparison of the policy manager 1026.
The pipeline manager 1022 requests to generate a pipeline for operation according to the request of the uMedia client from the media pipeline controller 102, with respect to resources assigned according to resource assignment of the resource manager 1024.
The media pipeline controller 1028 generates a necessary pipeline under control of the pipeline manager 1022. As shown, a media pipeline, a camera pipeline, a pipeline related to playback, pause or stop may be generated. The pipeline includes pipelines for HTML5, web CP, Smarthshare playback, thumbnail extraction, NDK, cinema, multimedia and hypermedia information coding experts group (MHEG), etc.
The pipeline may include a service-based pipeline and a URI based pipeline (media pipeline), for example.
Referring to
Accordingly, the application or service may cope with the request of the RM client via resource management of the resource manager 1024 via the uMS connector. The RM client may process services such as native CP, TV service, second screen, flash player, You Tube media source extensions (MSE), cloud game, Skype, etc. In this case, as described above, the resource manager 1024 may manage resources via appropriate data communication with the policy manager 1026 if necessary for resource management.
The URI based pipeline does not directly process the media unlike the above-RM client but processes the media via the media server 1020. The URI based pipeline may include player factory, Gstreamer, streaming plug-in, digital rights management (DRM) plug-in pipelines.
An interface method between the application and the media services is as follows.
An interface method using a service in a web application may be used. In this method, a Luna call method using a palm service bridge (PSB) and a method of using Cordova may be used, in which a display is extended to a video tag. In addition, a method of using HTML5 standard related to a video tag or media element may be used.
A method of using a service in PDK may be used.
Alternatively, a method of using in existing CP may be used. For backward compatibility, plug-in of an existing platform may be extended and used based on Luna.
Lastly, an interface method using a non-WebOS may be used. In this case, a Luna bus may be directly called to perform interfacing.
Seamless change is processed by a separate module (e.g., TVwin) and refers to a process of first displaying a TV program on a screen without a WebOS before or duration WebOS booting and then performing seamless processing. This is used for the purpose of first providing a basic function of a TV service, for fast response to a power-on request of a user, because a booting time of a WebOS is late. The module is a part of a TV service process and supports seamless change for providing fast booting and a basic TV function, factory mode, etc. The module is responsible for switching from the non-WebOS mode to the WebOS mode.
In
The service, the web application or the PDK application (hereinafter, referred to as “application”) is connected to various service processing components via a Luna-service bus and is operated or controlled via the service processing components.
A data processing path is changed according to application type. For example, if the application includes image data related to a camera sensor, the image data is transmitted to and processed by a camera processor 1130. At this time, the camera processor 1130 includes a gesture or face detection module and processes image data of the received application. The camera processor 1130 may generate a pipeline via a media server processor 1110 with respect to data which requires use of a pipeline according to user selection or automatically and process the data.
Alternatively, if the application includes audio data, the audio may be processed via an audio processor (AudioD) 1140 and an audio module (PulseAudio) 1150. For example, the audio processor 1140 processes the audio data received from the application and transmits the processed audio data to the audio module 1150. At this time, the audio processor 1140 may include an audio policy manager to determine processing of the audio data. The processed audio data is processed by the audio module 1150. The application or a pipeline related thereto may notify the audio module 1150 of data related to audio data processing. The audio module 1150 includes advanced Linux sound architecture (ALSA).
Alternatively, if the application includes or processes (hereinafter, referred to as “includes”) content subjected to DRM, the content data is transmitted to a DRM service processor 1160 and the DRM service processor 1160 generates a DRM instance and processes the content data subjected to DRM. The DRM service processor 1160 is connected to a DRM pipeline in a media pipeline via a Luna-service bus, for processing of the content data subjected to DRM.
Hereinafter, processing of an application including media data or TV service data (e.g., broadcast data) will be described.
Accordingly, a description will be given with reference to
First, if the application includes TV service data, the application is processed by the TV service processor 1120/1220.
The TV service processor 1120 includes at least one of a DVR/channel manager, a broadcast module, a TV pipeline manager, a TV resource manager, a data broadcast module, an audio setting module, a path manager, etc., for example. In
In the present specification, the TV service processor may have the configuration of
The TV service processor 1120/1220 transmits DVR or channel related data to a DVR/channel manager and transmits the DVR or channel related data to the TV pipeline manager to generate and process a TV pipeline, based on attribute or type of the TV service data received from the application. If the attribute or type of the TV service data is broadcast content data, the TV service processor 1120 generates and processes a TV pipeline via the TV pipeline manager, for processing of the data via a broadcast module.
Alternatively, a JavaScript standard object notation (j son) file or a file written in c is processed by the TV broadcast handler and transmitted to the TV pipeline manager via a TV broadcast interface to generate and process a TV pipeline. In this case, the TV broadcast interface may transmit the data or file passing through the TV broadcast handler to the TV pipeline manager based on TV service policy and refer to the data or file upon generating a pipeline.
The TV pipeline manager generates one or more pipelines according to a request for generation of a TV pipeline from the processing module or manager of the TV service processor, under control of the TV resource manager. The TV resource manager may be controlled by the TV policy manager, in order to request a resource assignment status for a TV service according to a request for generation of a TV pipeline of the TV pipeline manager, and may perform data communication with the media server processor 1110/1210 via a uMS connector. The resource manager in the media server processor 1110/1210 sends the resource assignment status for the TV service according to the request of the TV resource manager. For example, if the resource manager in the media server processor 1110/1210 determines that the resources for the TV service are already assigned, the TV resource manager may be notified that assignment of all resources is completed. At this time, the resource manager in the media server processor may remove a predetermined TV pipeline according to a predetermined criterion or priority of TV pipelines already assigned for the TV service along with notification and request generation of a TV pipeline for the requested TV service. Alternatively, the TV resource manager may appropriately remove a TV pipeline or may add or newly establish a TV pipeline according to a status report of the resource manager in the media server processor 1110/1210.
The BSP supports backward compatibility with an existing digital device.
The generated TV pipelines may appropriately operate under control of the path manager in the processing procedure. The path manager may determine or control the processing path or procedure of the pipelines in consideration of the TV pipeline in the processing procedure and the operation of the pipelines generated by the media server processor 1110/1210.
Next, if the application includes media data, not TV service data, the application is processed by the media server processor 1110/1210. The media server processor 1110/1210 includes a resource manager, a policy manager, a media pipeline manager, a media pipeline controller, etc. As pipelines generated under control of the media pipeline manager and the media pipeline controller, a camera preview pipeline, a cloud game pipeline, a media pipeline, etc. may be generated. The media pipeline may include streaming protocol, auto/static gstreamer, DRM, etc. and the processing flow thereof may be determined under control of the path manager. For a detailed description of the processing procedure of the media server processor 1110/1210, refer to the description of
In the present specification, the resource manager in the media server processor 1110/1210 may perform resource management to a counter base, for example.
Hereinafter, various embodiments of a digital device for processing a marquee service according to the present invention will be described in greater detail with reference to the accompanying drawings.
Referring to
In this case, the communication module 1310 receives text data by wire or wireless.
For instance, the communication module 1310 can connect Wi-Fi Direct for performing a device-to-device wireless communication and is also able to connect various wireless communications such as Wi-Fi, Bluetooth, Infrared communication, NFC (near field communication) and the like.
Subsequently, the display module 1330 can display the received text data within a text field.
The controller 1320 can control an operation of the digital device and performs a function of managing functions of at least one or more modules including the communication module 1310, the display module 1330 and the like overall.
The controller 1320 activates a text field on which the received text data will be displayed, checks whether an attribute type of the text field is a marquee attribute. As a result of the check, if the attribute type of the text field is the marquee attribute, the controller 1320 can perform a function of moving a text displayed within the text field in a preset direction.
As a result of the check, if the attribute type of the text field is not the marquee attribute, the controller 1320 checks whether the text data includes the marquee attribute. If the text data includes the marquee attribute, the controller 1320 can switch the attribute type of the text field to the marquee attribute.
For instance, as a result of the check, if the attribute type of the text field is not the marquee attribute, the controller 1320 checks whether the text data includes the marquee attribute. If the text data includes the marquee attribute, the controller 1320 checks whether a priority of the attribute of the text data is higher than that of the attribute of the text field. If the priority of the attribute of the text data is higher than that of the attribute of the text field, the controller may switch the attribute type of the text field to the marquee attribute.
For another instance, as a result of the check, if the attribute type of the text field is the marquee attribute, the controller 1320 extracts a setup value for the marquee attribute of the text field and is able to perform the marquee function of moving a text displayed within the text field in a preset direction.
For further instance, if a change request signal of a setup value is received, the controller 1320 creates and displays a setting change window. If the setup value is changed through the setting change window, the controller 1320 creates and displays a user equerry message window for querying whether to save the changed setup value. If a save request signal of the changed setup value is received from the user equerry message window, the controller 1320 may save the changed setup value.
Referring to
For instance, as shown in
Subsequently, referring to
The digital device 1410 then checks whether an attribute type of the text field 1430 is a marquee attribute.
For instance, the digital device 1410 checks whether the text data 1440 displayed within the text field 1430 exceeds a size of the text field 1430. As a result, if the displayed text data 1440 exceeds the size of the text field 1430, the digital device 1410 may check whether the attribute type of the text field 1430 is the marquee attribute.
In this case, only if a capacity of the text data 1440 exceeds the size of the text field 1430, the digital device 1410 can perform a marquee function.
For another instance, when the digital device 1410 checks whether the attribute type of the text field 1430 is the marquee attribute, as a result of the check, if the attribute type of the text field 1430 is not the marquee attribute, the digital device 1410 checks whether the text data 1440 includes the marquee attribute. As a result of the check, if the text data 1440 includes the marquee attribute, the digital device 1410 may switch the attribute type of the text field 1430 to the marquee attribute.
In this case, the digital device 1410 may determine whether to perform the marquee function by analyzing the attribute type of the text data 1440 as well as the attribute type of the text field 1430.
In doing so, when the digital device 1410 switches the attribute of the text field 1430 to the marquee attribute, if the text data 1440 includes the marquee attribute, the digital device 1410 creates and displays a user query message window for querying whether to switch the text field 1430 to the marquee attribute. If a marquee attribute switch request signal of the text field 1430 is received from the user query message window, the digital device 1410 may switch the attribute type of the text field 1430 to the marquee attribute.
In this case, a user may not desire to switch the attribute type of the text field 1430 to the marquee attribute. To prevent such switching, the digital device 1410 displays the user query message window for querying whether to switch the text field 1430 to the marquee attribute, thereby providing the user with convenience.
For further instance, when the digital device 1410 checks whether the attribute type of the text field 1430 is the marquee attribute, if the attribute type of the text field 1430 is not the marquee attribute, the digital device 1410 checks whether the text data 1440 includes the marquee attribute. If the text data 1440 includes the marquee attribute, the digital device 1410 checks whether a priority of the attribute of the text data 1440 is higher than that of the attribute of the text field 1430. If the priority of the attribute of the text data 1440 is higher than that of the attribute of the text field 1430, the digital device 1410 may switch the attribute type of the text field 1430 to the marquee attribute.
In this case, the digital device 1410 can determine whether to perform the marquee function by analyzing the attribute type of the text data 1440 as well as the attribute type of the text field 1430, and more particularly, by depending on a higher priority attribute.
For example, when the marquee attribute is not included in the text field 1430 but included in the text data 1440, if the priority of the attribute of the text field 1430 is higher than that of the attribute of the text data 1440, the marquee function may not be performed. Yet, if the priority of the attribute of the text field 1430 is lower than that of the attribute of the text data 1440, the marquee function may be performed.
In doing so, when the digital device 1410 switches the attribute of the text field 1430 to the marquee attribute, if the priority of the attribute of the text data 1440 is higher than that of the attribute of the text field 1430, the digital device 1410 creates and displays a user query message window for querying whether to switch the text field 1430 to the marquee attribute. If a marquee attribute switch request signal of the text field 1430 is received from the user query message window, the digital device 1410 may switch the attribute type of the text field 1430 to the marquee attribute.
Referring to
In doing so, when the digital device 1410 moves the text displayed within the text field 1430 in the preset direction, if the attribute type of the text field 1430 is the marquee attribute, the digital device 1410 extracts a setup value for the marquee attribute of the text field 1430 and is then able to perform the marquee animation function of moving the text displayed within the text field 1430 in the preset direction according to the extracted setup value.
In this case, the setup value may include a text moving direction, a text moving speed, a text moving control signal, a text moving repeated count, a text moving quantity, or the like, by which the setup value is non-limited.
For example, the text moving control signal may include a cursor signal of a remote controller, a user's touch signal, a user's gesture signal, a user's pupil motion signal, or the like.
In some cases, the setup value may be changed according to a country language of a text.
For example, with respect to the country language of the text, since Korean, English or the like is arranged to be readable in left-to-right direction, the marquee animation function can be given in a manner of moving Korean or English text in right-to-left direction.
For another example, with respect to the country language of the text, since Hebrew is arranged to be readable in right-to-left direction, the marquee animation function can be given in a manner of moving Hebrew text in left-to-right direction.
Therefore, the present invention varies a setup value according to a country language of a text, thereby providing a user with convenience.
For another instance, a setup value may be changed according to a type of the text field 1430.
For example, a type of the text field 1430 may include a broadcast program related EPG type, a news caption type, a movie caption type, a song lyric type, or the like.
When the text field 1430 of a prescribed type includes a multitude of subfields, a setup value of a subfield may be equal to that of the text field 1430.
Namely, the setup value of the subfield may depend on a main setup value of the text field 1430.
Yet, in some cases, when the text field 1430 of a prescribed type includes a multitude of subfields, a setup value of a subfield may be different from that of the text field 1430.
Namely, the setup value of the subfield may not depend on a main setup value of the text field 1430.
In this case, when the text field 1430 of a prescribed type includes a multitude of subfields, the subfields may differ from each other in setup value. Yet, in some cases, the setup values of the subfields may be equal to each other.
When the digital device 1410 moves a text displayed within the text field 1430 in a preset direction, if a setup value change request signal is received, the digital device 1410 displays a setting change window. If a setup value is changed through the setting change window, the digital device 1410 creates and generates a user query message window for querying whether to save the changed setup value. If a save request signal of the changed setup value is received from the user equerry message window, the digital device 1410 can save the changed setup value.
In this case, a user may not desire to change the setup value of the text field 1430. To prevent this, the digital device 1410 displays the user query message window for querying whether to change the setup value of the text field 1430, thereby providing the user with convenience.

For example, as shown in
Subsequently, the digital device 1510 displays a text data 1540 within the activated text field 1530. The digital device 1510 then checks whether the text data 1540 displayed within the text field 1530 exceeds a size of the text field 1530. As a result of the check, if the displayed text data 1540 exceeds the size of the text field 1530, the digital device 1510 can check whether an attribute type of the text field 1530 is a marquee attribute.
Referring to
In this case, only if a capacity of the text data 1540 exceeds the size of the text field 1530, the digital device 1510 can perform a marquee function.

For example, as shown in
Subsequently, the digital device 1610 displays a text data 1640 within the activated text field 1630 and is able to check whether an attribute type of the text field 1630 is a marquee attribute.
In doing so, when the digital device 1610 checks whether the attribute type of the text field 1630 is the marquee attribute, if the attribute type of the text field 1630 is not the marquee attribute, the digital device 1610 checks whether the text data 1640 includes the marquee attribute. If the text data 1640 includes the marquee attribute, the digital device 1610 may switch the attribute type of the text field 1630 to the marquee attribute.
Namely, referring to
Thus, the present invention gives a marquee animation function to a corresponding text in a manner that a marquee attribute is included in a text data requiring user's concern and intention, thereby providing the user with advertisement and PR (public relations) effects.
In particular, the digital device 1610 may determine whether to perform the marquee function by analyzing the attribute type of the text data 1640 as well as the attribute type of the text field 1630.
Referring to
In doing so, when the digital device 1710 switches the attribute of the text field 1630 to the marquee attribute, if the text data 1640 includes the marquee attribute, the digital device 1710 creates and displays a user query message window 1650 for querying whether to switch the text field 1630 to the marquee attribute.
For example, a marquee attribute switch approve button 1660 and a marquee attribute switch decline button 1660 of the text field 1630 can be included in the user query message window 1650 for querying whether to switch the text field 1630 to the marquee attribute.
Hence, if a marquee attribute switch request signal of the text field 1630 is received from the user query message window 1650, the digital device 1710 may switch the attribute type of the text field 1630 to the marquee attribute.
For example, if a special event related text data 1640 in the text data 1640 of the broadcast program related EPG type includes the marquee attribute, the digital device 1710 switches an attribute type of the text field 1630, on which a text ‘special event’ is displayed, to the marquee attribute and is able to perform a marquee animation function of moving the text ‘special event’ displayed within the text field 1630 in a preset direction.
In this case, a user may not desire to switch the attribute type of the text field 1630 to the marquee attribute. To prevent such switching, the digital device 1710 displays the user query message window 1650 for querying whether to switch the text field 1630 to the marquee attribute, thereby providing the user with convenience.
Referring to
For example, when the digital device 1810 moves the text displayed within the text field 1830 in the preset direction, if the attribute type of the text field 1830 is the marquee attribute, the digital device 1810 extracts a setup value for the marquee attribute of the text field 1830 and is then able to perform the marquee animation function of moving the text displayed within the text field 1830 in the preset direction according to the extracted setup value.
In this case, the setup value may include a text moving direction, a text moving speed, a text moving control signal, a text moving repeated count, a text moving quantity, or the like, by which the setup value is non-limited.
