That is, in FIG. 1, a remote user interface client (RUIC) 120, which is a client device, consumes content provided by a remote user interface server (RUIS) 110 using a remote UI page and control information. Shows.

Referring to FIG. 1, the RUIC 120 receives both a remote UI page and audio and video contents provided by the RUIS 110, and provides a desired content service by the remote UI page and audio and video contents. to provide.

In this case, the RUIC 120 receives only the contents corresponding to its device capability from the RUIS 110 to serve. In such an environment, the format, format, and user experience of the content that can be experienced by the user depend entirely on the capability of the single RUIC 120.

For example, a client device with a high ability for video resolution and image quality that the RUIC 120 can render, but with a very low ability to play audio content, would have a user capable of viewing satisfactory video footage but with a low quality. You will have no choice but to accept audio content of sound quality.

Therefore, in order to overcome the limitation of the content service provided by the existing remote UI system, it is urgent to prepare a method for distributing and processing the RUICs having the best capability for various kinds of element contents according to a specific content service provided from RUIS.

In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

In the detailed description according to an embodiment of the present invention to be described later, a remote user interface (RUI), a remote user interface server (RUIS), a remote user interface client (RUIC), a control RUIC, a target RUIC, a UI Terms such as data, content service, content data, element content, element content data, etc. will be used. The terms may be defined as follows.

RUI: A user interface provided to a client device for a specific content service in a server in a remote UI system.

RUIS: A server that provides a requested content service from a client device in a remote UI system, and provides element content for the requested content service to be distributed to selected client devices.

RUIC: A client device that receives and processes content or element content (UI page, video content, audio content, etc.) from RUIS.

Control RUIC: refers to a client device that serves to provide a UI page from the RUIS to a user or to control content in service by a user's request.

Target RUIC: means a client device that is selected by the control RUIC and receives and processes the element content allocated to itself among the element contents for the content service requested by the control RUIC from the RUIS.

UI data: refers to data that RUIC receives from RUIS to provide UI pages to users.

Content Services: means all services provided by RUIS for RUIC.

Content data: means all data provided from RUIS for content services.

Element Content: Refers to detailed content such as UI page, video content, audio content, etc. which can be provided as RUIC for one content service.

Element content data: Means data provided from the RUIS to the target RUIC corresponding to the element content.

Service identification information: refers to information for identifying that elementary contents for one content service are provided by a request of the same user.

Meanwhile, terms that are not defined above and used in the detailed description to be described below may be defined by the details.

Meanwhile, in an embodiment of the present invention to be described below, in response to a content service request of a specific RUIC, the RUIS distributes the element contents for the requested content service to the specific RUIC and at least one target RUIC.

To this end, according to an embodiment of the present invention, a procedure according to an improved protocol for delivering each selected element content (eg Audio, Video, Control UI Page) to a selected target RUIC must be newly defined. .

The following items should be defined in the improved protocol.

First, a scheme must be devised to distinguish that various types of elementary contents constituting one content service are for a specific user. If information on this is not provided at the level of the application layer, the lower layer transmitting the content cannot distinguish it, and thus, the user may receive a service in which the element contents are not synchronized with each other.

In other words, RUIS transmits each media stream or contents by client's request. However, RUIS does not know which user it is for. In this case, the user has no choice but to consume the received media contents with a slight time difference.

Secondly, in order to control the content being rendered in the target RUIC, a control command structure and a definition thereof are required so that information about the target client device to which the control result is reflected can be known.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Meanwhile, in the drawings for describing the present invention, the same elements will be noted with the same reference numerals and symbols as much as possible even though they are shown in different drawings.

2 conceptually illustrates an example of providing a content service in a remote UI system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, assuming that element contents for a content service desired by a user are composed of UI pages, video contents, and audio contents, the RUIS 210 selects at least one element contents of the element contents. It is distributed and provided to different client devices, RUIC 1 220 and RUIC 2 230.

In this case, the RUIC 1 220 is a client device that receives a UI page from the RUIS 210 and controls a corresponding content service based on a remote UI. The RUIC 2 230 is an optimal client device for processing video and audio content according to a corresponding content service among devices constituting a network. That is, the RUIC 2 230 may be an optimal client device that receives and processes video and audio content from the RUIS 210.

Here, the optimal client device for processing each element content may be a client device having a relatively high ability to process the element content compared to the case where all the element contents according to the corresponding content service are processed by one client device. . For example, a PDA may be used as the RUIC 1 220, and an LCD television may be used as the RUIC 2 230.

3 conceptually illustrates another example of providing a content service in a remote UI system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, assuming that element contents for a content service desired by a user are composed of UI pages, video contents, and audio contents, the RUIS 310 may designate each of the element contents as different client devices. RUIC 1 (320), RUIC 2 (330), RUIC 3 (340) to provide the distribution.

In this case, the RUIC 1 320 is a client device capable of controlling a corresponding content service based on a remote UI. The RUIC 2 330 is an optimal client device for processing video content according to a corresponding content service among devices constituting a network. The RUIC 3 340 is an optimal client device for processing audio content according to a corresponding content service among devices constituting a network.

Here, the optimal client device for processing each element content may be a client device having a relatively high ability to process the element content compared to the case where all the element contents according to the corresponding content service are processed by one client device. . For example, a PDA may be used as the RUIC 1 320, an LCD television may be used as the RUIC 2 330, and Hi-Fi audio may be used as the RUIC 3 340.

If a user watches a movie using a content service provided by RUIS using only a PDA, the user may be dissatisfied with the small screen and poor sound. However, according to the schemes of FIGS. 2 and 3, it is possible to enjoy high-quality sound with Hi-Fi audio while watching a movie on a large screen with an LCD television. In addition, when controlling the content service, desired control may be possible using a UI provided through a PDA. Of course, it is also possible to control the corresponding element content through a client device that processes each element content.

4 illustrates signaling for providing a content service in a remote UI system according to an exemplary embodiment of the present invention. That is, FIG. 4 illustrates a procedure for distributing and distributing various element contents constituting one content service to a plurality of client devices in a remote server (RUIS).

For example, in FIG. 4, element contents of one content service are divided into audio, video, and UI pages. In addition, it is assumed that RUIC 1 is a control device for controlling the corresponding content service by the UI page, RUIC 2 is assumed to be a video device supporting video content corresponding to the corresponding content service, and RUIC 3 corresponds to the corresponding content service. It is assumed that the audio device supports audio content.

However, unlike the assumption in FIG. 4, not only can target various element contents but also one RUIC can support a plurality of element contents. That is, RUIS 1 may support UI page and audio content together, or RUIC 2 or RUIC 3 may support video content and audio content together. Only for the embodiment of the present invention, a condition that a plurality of element contents constituting one content service should be distributed by a plurality of RUICs must be satisfied.

In detail, referring to FIG. 4, in step 410, the RUIC 1 searches for devices existing in the vicinity by an existing protocol. In this case, the target device to be searched by the RUIC 1 may be another RUIC as well as a RUIS located nearby.

If the RUIC 1 is found through the discovery of the peripheral device, the RUIC 1 receives a UI list from the searched RUIS in step 412. The UI list may be a list including information on content services that can be provided by the RUIS. Although not shown in the drawing, the UI list may be provided from the RUIS in response to a request of the RUIC 1.

In step 414, the RUIC 1 selects a desired content service based on the UI list. That is, the UI page required to receive the desired content service is selected. In step 414, the RUIC 1 selects at least one target RUIC to distribute and process the selected content service among the devices previously searched, that is, the RUICs located in the vicinity. The RUIC 1 considers the element contents constituting the selected content service in selecting the target RUIC. For example, if video content and audio content exist as elementary contents constituting the selected content service, a target RUIC to process the video content and a target RUIC to process the audio content are selected differently. In this case, preferably, the target RUIC is selected as the RUIC having the highest capability in processing each element content among the searched RUICs.

When the selection of the specific UI page and the target device is completed, the RUIC 1 requests the RUIS to provide the selected specific UI page in step 416. Thereafter, the RUIC 1 receives UI data corresponding to a desired UI page from the RUIS in step 418.

In step 420, the RUIC 1 parses the UI data provided from the RUIS, and as a result, displays the UI page through a user interface provided for the user to check.

Meanwhile, the RUIC 1 extracts location information to be accessed to obtain data corresponding to desired element content, that is, element content data, through parsing the provided UI data. For example, the location information may be URL information.

The RUIC 1 extracts the location information for each element content for the selected content service, and transfers the extracted location information to the target RUIC in steps 422 and 424. That is, the RUIC 1 transmits the location information in which the element content data of the video type exists in step 422 to the corresponding target RUIC RUIC 2, and the location information in which the element content data of the audio type exists in the step 424 RUIC in the corresponding target RUIC. Pass to 3.

Meanwhile, the RUIC 1 may transmit identification information together with the location information to the target RUIC in steps 422 and 424. The identification information is information for identifying that element content data delivered by the RUIS to different devices for one content service are for the same user. Accordingly, the RUIS can confirm that the same user's request is requested by the identification information even though different element content data are requested from a plurality of RUICs for one content service.

The RUIS responds to the request of the RUIC 2 (step 426) to provide the video content data present in the location information to the RUIC 2 in step 430, and in step 432 in response to the request of the RUIC 3 (step 428). The audio content data present in the location information is provided to the RUIC 3.

In this case, the RUIS may recognize that the video content data provided to the RUIC 2 and the audio content data provided to the RUIC 3 are provided for the same user by the identification information defined above. Therefore, it is preferable that the RUIS provides the video content data and the audio content data provided by the same identification information in consideration of the synchronization during processing by the target RUIC.

By the above-described procedure, the user can listen to the audio content through RUIC 3 while watching the video content through RUIC 2. This allows a user to use a desired content service by devices that can increase satisfaction for each content.

Meanwhile, the user may control the corresponding content service while using the corresponding content service. This may be done through the corresponding RUIC for each element content, but FIG. 4 assumes that the content is made by the RUIC 1 providing the UI page.

Therefore, the user will request control of the content service currently being used by using the UI page provided by RUIC 1. In this case, the RUIC 1 provides control information corresponding to the request of the user to the RUIS in step 434.

The RUIS may update the currently provided content service according to the control information provided from the RUIC 1 and change the video and audio content provided to the RUIC 2 and the RUIC 3 to correspond to the updated content service. . That is, the RUIS allows the result of the control of the RUIC 1 to be reflected in the element content data provided to the remaining RUIC.

As such, the identification information defined above may be used to accurately reflect the result of the control of the RUIC 1 to the element content data provided to the other RUIC. That is, the RUIS allows the control result to be reflected only on the element content data provided by the identification information that matches the identification information of the control information.

FIG. 5 illustrates an operation for providing a content service by details of a remote server (RUIS) 10 and a client device (RUIC) 20 and 30 constituting a remote UI system according to an exemplary embodiment of the present invention.

According to FIG. 5, the remote UI system is composed of one RUIS 10 and two RUICs 20 and 30. Among the two RUISs 20 and 30, RUIC 1 20 is a client device that processes UI pages and video content, and RUIC 2 30 is a client device that processes audio content. In this case, the UI page and video content to be processed by the RUIC 1 20 and the audio content to be processed by the RUIC 2 30 are element content corresponding to one content service. Accordingly, in the remote UI system illustrated in FIG. 5, UI pages, video content, and audio content corresponding to element content are distributed and processed by different client devices.

To this end, the RUIS 10 includes an identification information management module 12, a media server module 14, and a web server module 16. The RUIC 1 20 includes a web browser module 22, a connection control module 24, and a renderer 26, and the RUIC 2 30 includes a web browser module 32 and a renderer 34. do.

First, a detailed configuration of the RUIS 10, the web server module 16 includes an optional UI page providing module as a logical entity. The optional UI page providing module provides a UI page for corresponding element content in response to a request of each RUIC (20, 30). That is, the optional UI providing module distributes each of the plurality of element contents for one content service into a plurality of RUICs.

For example, the optional UI providing module provides the RUIC 1 20 with a UI page for a corresponding content service and a UI page of video content that is element content for the corresponding content service. The UI page of the audio content which is the element content for the corresponding content service is provided to the RUIC 2 30.

The identification information management module 12 manages service identification information for identifying a content service for each user. In this case, the service identification information is used to identify a user who requested any content service. Therefore, even if it is requested to provide different element content from a plurality of RUIC, if the request is made by the same service identification information it can be confirmed that the request corresponding to the same content service. And even when a change is made to the content service being provided, the service identification information may be used to uniformly reflect the plurality of RUICs.

To this end, the identification information management module 12 manages service identification information, and generates service identification information for identifying it in response to a request for a new content service, if necessary.

The media server module 14 provides the video server or audio content to the web server module 16 when a video content request or an audio content request is provided from the web server module 16. At this time, if the media server module 14 can recognize that the video content and the audio content requested by the web server module 16 have the same service identification information, the media server module 14 outputs the video content and the audio content in synchronization.

Next, referring to the detailed configuration of the RUIC 1 (20), the web browser module 22 parses the UI page provided from the RUIS 10 and outputs it through the user interface. In addition, the web browser module 22 requests the RUIS 10 to provide video content, which is element content to be processed. At this time, the web browser module 22 transmits service identification information corresponding to the content service using the video content as the element content to the RUIS 10. In addition, the web browser 22 receives the video content requested by the RUIS 10 and delivers the video content to the renderer 26 to process the video content.

The connection control module 24 selects at least one target RUIC to process each element content for a content service to be provided. To this end, the connection control module 24 may embed a separate UI page for selecting a target RUIC.

In addition, the connection control module 24 interoperates with a UICP (User Interface Control Point) to instruct at least one target RUIC selected for a desired content service to request RUIS 10 the designated element content. To this end, the connection control module 24 parses a specific UI page provided from the RUIS 10 and extracts location information (eg, URL information) to which the target RUIC is to access to receive the specified element content. In this case, the location information of the specific element content may be extracted by referring to information such as a MIME type described on the UI page. The connection control module 24 transfers the previously extracted location information to the corresponding target RUIC through the web browser module 22.

The connection control module 24 also provides service identification information at the application level to the target RUIC to process the element content. When the service identification information requests that each of the plurality of target RUICs provide the desired element content to the RUIS 10, the RUIS 10 requests only the specific user whose element contents requested from the plurality of target RUICs. It is used to identify the purpose. That is, the service identification information may be used for the purpose that the RUIS 10 recognizes that element contents requested by a plurality of target RUICs are related to each other.

The renderer 26 receives the video content provided from the RUIS 10 through the web browser module 22, renders the video content, and outputs it for viewing by a user through a user interface.

Finally, referring to the detailed configuration of the RUIC 2 (30), the web browser module 32 is provided from the RUIC 1 (20) is provided with the location information and the service identification information that the audio content is the element content to be processed. The web browser module 32 requests the RUIS 10 to provide audio content that is element content to be processed. At this time, the web browser module 32 transfers the service identification information provided from the RUIC 1 (20) to the RUIS (10). In addition, the web browser 32 receives the audio content requested by the RUIS 10 and delivers the audio content to the renderer 34 to process the audio content.

In detail, the identification information management module 12 of the RUIS 10 corresponds to the requested content service among the identification information managed by the user in step 508. The identification information is provided to the web server module 16. The web server module 16 provides UI data corresponding to the UI page for the content service requested in step 510 to the web browser module 22 of the RUIC 1 20. In the UI data, identification information corresponding to a request of the corresponding content service provided by the identification information management module 12 is embedded.

The UI data is provided to the connection control module 24, and the connection control module 24 parses a UI page based on the UI data, and through the parsing, each of the element contents for the requested content service. Obtain location information to access in order to be provided. In this case, the location information may be URL (Uniform Resource Location) information.

The connection control module 24 transmits the location information and the service identification information acquired for each element content to the RUIC to process each element content in step 512. In FIG. 5, it is assumed that RUIC 1 20 processes video content and RUIC 2 30 processes audio content.

Therefore, since the connection control module 24 belongs to RUIC 1 20, the connection control module 24 does not transmit location information and service identification information corresponding to video content to other RUICs. Only the connection control module 24 passes the location information and service identification information corresponding to the video content to the renderer 26 which will process the video content within the RUIC 1 20 to which it belongs.

However, since audio content must be processed in RUIC 2 30, the connection control module 24 provides location information and service identification information corresponding to the audio content to RUIC 2 30.

The location information and the service identification information transmitted by the connection control module 24 are provided to the web browser module 32 constituting the RUIC 2 30, and the web browser 32 in step 514. Based on this, the REQUESTED_PROFILE requesting the provision of the audio content, which is the element content to be processed, is delivered to the web server module 16 of the RUIS 10. At this time, the REQUESTED_PROFILE includes the service identification information defined above as well as the position information corresponding to the audio content that is the corresponding element content.

In operation 518, the web browser 22 of the RUIC 1 20 may request a REQUESTED_PROFILE requesting provision of video content, which is element content to be processed, based on the location information provided by the connection control module 24. Transfer to the web server module 16 of the RUIS (10). At this time, the REQUESTED_PROFILE includes the service identification information defined above as well as the location information corresponding to the video content that is the corresponding element content. In addition, information about element content that the user wishes to receive may be added to the REQUESTED_PROFILE.

In step 516, the web server module 16 performs a service identification information check procedure with the identification information management module 12 using the service identification information included in the REQUESTED_PROFILE from the RUIC 2 30.

In operation 520, the web server module 16 performs a service identification information checking procedure with the identification information management module 12 using the service identification information included in the REQUESTED_PROFILE from the RUIC 1 20.

The web server module 16 is a user whose video content requested from the RUIC 1 (20) and the audio content requested from the RUIC 2 (30) are the same by the identification information confirming procedure with the identification information management module (12). Confirm that it is for one content service requested by.

The web server module 16 then provides the video content supplied from the media server module 14 to the renderer 26 via the web browser module 22 of the RUIC 1 20 in step 522. In addition, the web server module 16 provides the audio content supplied from the media server module 14 to the renderer 34 through the web browser module 32 of the RUIC 2 30 in operation 524. At this time, the optional UI page providing module of the web server module 16 includes the video content in the UI page and delivers it to the RUIC 1 (20), and includes the audio content in the UI page to the RUIC 2 (30). I can deliver it. To this end, the optional UI providing module should be able to generate UI pages separately for each element content.

The web server module 16 corresponds to the same content service as the video content provided to the renderer 26 of the RUIC 1 20 and the audio content provided to the renderer 26 of the RUIC 2 30. According to this, the two element contents are synchronized and provided. This is to allow the video screen to be output through the RUIC 1 (20) and the audio screen to be output through the RUIC 2 (30) to be synchronized. Synchronization by the web server module 16 may be performed using a time offset.

As can be seen from the above-described operation description, according to an embodiment of the present invention, desired element content may be used by a client device designated by the user for each element content. At this time, the association between the element contents output to different client devices is recognized, and through this, service identification information at the application level is utilized to synchronize the element contents.

Meanwhile, in the above-described operation, it is assumed that service identification information is generated by the identification information management module constituting the RUIS 10 and transmitted to the RUICs.

As another method, however, the RUIC requesting the content service for the first time may generate service identification information corresponding to the content service requested by the user. In this case, the first RUIC requesting a content service corresponds to a RUIC having a connection control module. In this case, the RUIC generating the service identification information should be able to transmit the service identification information to the RUIS as well as the RUIC to process the audio content. For example, when the RUIC including the connection control module requests a desired content service to the RUIS, the service identification information is transmitted.

6 is a flowchart illustrating a control for a content service in a remote UI system according to an exemplary embodiment of the present invention. That is, FIG. 6 illustrates a procedure for controlling the various element contents (e.g. Audio, Video) being transmitted to the multiple target RUICs 20 and 30, respectively. Control of the various element contents is performed through a remote UI page rendered in RUIC 1 (20). At this time, the role and function of the control command management module 18, which is a software module additionally required for the RUIS 10, is additionally required. Meanwhile, in FIG. 5, the RUIC 1 20 simultaneously serves as a control RUIC for controlling various element contents and a target RUIC for processing video content which is element contents.

The control command management module 18 serves to distinguish which target RUIC the control command (e.g. Play, Pause, Stop, etc.) received from the RUIC 1 20 should be reflected. To this end, the RUIC 1 20 adds service identification information to a control command signal and transmits it to the RUIS 10.

Accordingly, the control command management module 18 targets the RUIC 2 30 having the same service identification information as the service identification information received from the RUIC 1 20 among the target RUICs providing the element content. Determined by RUIC. The control command module 18 transmits the control command received from the RUIC 1 20 to the media server module 14. Accordingly, the media server module 14 provides the audio content reflecting the control result according to the execution of the control command to the RUIC 2 30 which is the corresponding target RUIC.

Referring to the control procedure according to the above configuration in more detail, the web browser module 22 of the RUIC 1 (20) transmits a control command including the service identification information to the RUIS (10). The web server module 16 of the RUIS 10 transmits a control command from the RUIC 1 20 to the control command management module 18 in step 612.
