Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Jul. 12, 2012 in the Korean Intellectual Property Office and assigned Serial No. 10-2012-0076304 and of a Korean patent application filed on Mar. 25, 2013 in the Korean Intellectual Property Office and assigned Serial No. 10-2013-0031673, the entire disclosure of each of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to multimedia elements. More particularly, the present disclosure relates to a method of composing a markup for spatially and temporally arranging and synchronizing multimedia elements.

BACKGROUND

The demand for multimedia services has continuously increased, and the necessities of providing various multimedia services for current display devices and configuring a new markup for the provision of the various multimedia services have also increased.

A technology defining a multimedia element on the web largely includes a Hypertext Markup Language (HTML) and a Synchronized Multimedia Integration Language (SMIL). Hereinafter, the HTML and the SMIL will be described in more detail with reference to FIGS. 1 and 2.

FIG. 1 illustrates an HTML document structure in a multimedia communication system according to the related art.

Referring to FIG. 1, the HTML is a markup language for defining a hypertext document structure, and corresponds to a technology most widely used on the web today, of which revision work of version 5 is currently being completed. HTML version 5 has enhanced support for multimedia services such as a video, audio and the like, but cannot support functions such as temporal composition or interaction of the media, synchronization, and the like since the HTML is basically a language for defining a structure of a static document.

As illustrated in FIG. 1, the HTML document structure includes <header>, <nav>, <section>, <article>, <footer>, and <aside>.

<header> indicates a logo area, <nav> indicates a menu area, <section> indicates contents of the body, <article> indicates a main content area within the body, <footer> indicates a lower part of a site, and <aside> indicates a sub area or an advertisement content area.

FIG. 2 illustrates an example of arranging multimedia elements by using the SMIL in a multimedia communication system according to the related art.

Referring to FIG. 2, the SMIL is the World Wide Web Consortium (W3C) standard established for temporally and spatially composing and controlling multimedia data such as videos, audio, images, text and the like on the web by using an eXtensible Markup Language (XML).

As illustrated in FIG. 2, there is an advantage of temporally and spatially composing and controlling the multimedia data through the use of the SMIL. However, since the SMIL is defined by the XML, the SMIL requires a separate player in order to render a document defined by the SMIL, and accordingly, corresponds to the standard which is not actually used in current industrial fields.

As described, although the multimedia elements are defined by the aforementioned HTML or SMIL, both the HTML and the SMIL can only compose the media and neither can configure the scene including a plurality of areas. Accordingly, there exists a need for an apparatus and method for dividing multimedia elements into scene, area, and media levels to configure a markup.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a method and an apparatus for dividing multimedia elements into scene, area, and media levels to configure a markup.

Another aspect of the present disclosure is to provide a method and an apparatus for temporally and/or spatially composing multimedia elements in a multimedia communication system and configuring a markup which can support synchronization between the multimedia.

In accordance with an aspect of the present disclosure, a method of configuring a markup for composition of multimedia elements in a multimedia communication system is provided. The method includes configuring a markup including scene composition information, area description information, and multimedia description information and spatially and temporally composing multimedia elements according to the configured markup.

In accordance with another aspect of the present disclosure, a display device for configuring a markup for composition of multimedia elements in a multimedia communication system is provided. The display device includes a markup configuration unit configured to configure area description information corresponding to each of a plurality of areas included in a scene, to configure multimedia description information corresponding to at least one multimedia included in each of the plurality of areas, to configure scene composition information describing spatial composition and temporal composition of each of the plurality of areas, and to configure a markup including the scene composition information, the area description information, and the multimedia description information, and a display unit configured to display the scene based on the markup.

The present disclosure can not only spatially and/or temporally compose multimedia elements but also provides a synchronization means between the multimedia. Further, a basic scene can be configured in a browser which cannot support an extensible markup. In addition, the present disclosure provides a means which can variously configure and use scene information in a plurality of devices in the future by separating scene description information and actual area description and media expression information.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the present disclosure.

DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,”“an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

FIG. 3 illustrates an example of configuring a scene for a display device in a multimedia communication system according to an embodiment of the present disclosure.

Referring to FIG. 3, a shown scene 300 is the uppermost end within the structure of a document, and there may be multiple scenes 300 within the document. For example, when it is assumed that a broadcast program for one hour consists of scenes, the broadcast program may be configured by scene #1 included the first 30 minutes and scene #2 included in the second 30 minutes.

One scene 300 is divided into a plurality of areas. The number of areas may be one to n based on one scene. Further, the area may be considered as an independent unit, and a current independent broadcast program, a Video on Demand (VoD) service, or a document of a web service may be considered as one area. That is, independent areas 310, 320, and 330 are gathered to form one scene 300.

One area consists of a plurality of multimedia. The multimedia may include all media data such as videos, audio, images, text and the like. That is, the areas 310, 320, and 330 include multimedia 315, 325, and 335, respectively.

Hereinafter, a method of configuring a markup for the scene 300 illustrated in FIG. 3 will be described with reference to FIGS. 4A and 4B according to embodiments of the present disclosure.

FIG. 4A illustrates an example of configuring a markup in a multimedia communication system according to a first embodiment of the present disclosure.

Referring to FIG. 4A, a shown markup document includes scene composition information 400, scene description information 410, and areas included in the scene 300. Moreover, multimedia information corresponds to information on the markup document in a one to one relationship. That is, each element of the area 310 and the multimedia 315 is expressed by area description information 420 and multimedia description information 425, each element of the area 320 and the multimedia 325 is expressed by area description information 430 and multimedia description information 435, and each element of the area 330 and the multimedia 335 is expressed by area description information 440 and multimedia description information 445.

The scene composition information 400 describes space composition and time composition of each of the areas included in the scene. Actual information on each area separately exists so that the areas can operate individually. Further, a plurality of scenes can be configured in one document by separately describing the space composition and the time composition of the scene.

Although one scene composition information 400 is illustrated in FIG. 4A, the number of scene composition information 400 may be plural to express a plurality of scenes including scene #1, scene #2, etc. Further, although the scene composition information 400 is described together with the time information and the space information in FIG. 4A, the time information and the space information can be separately described. Hereinafter, an example of separately describing the time information and the space information will be described with reference to FIG. 4B according to an embodiment of the present disclosure.

FIG. 4B illustrates an example of configuring a markup in a multimedia communication system according to a second embodiment of the present disclosure.

Referring to FIG. 4B, a separate markup document 401 including scene composition information 450 and multimedia time information 455 describing time information of each multimedia included in the scene is configured, and scene description information 460 including basic area description information 470, 480, and 490 and multimedia description information 475, 485, and 495 are described as one markup document. In this case, a browser reads the markup document indicating the scene description information 460 and the separate markup document 401 indicating the scene composition information 450 and the multimedia time information 455 together to configure a final scene. As described above, when the scene composition information 450 and the multimedia time information 455 are configured as the separate markup document, a browser which cannot support the method provided by the present disclosure also can display the scene description information 460.

FIG. 5A illustrates the markup configured in the multimedia communication system and an example of a scene executed based on the markup according to the first embodiment of the present disclosure. That is, FIG. 5A illustrates an example of a scene executed based on the markup configured according to the method of FIG. 4A.

Referring to FIG. 5A, the shown markup document includes scene composition information, scene description information, area description information, multimedia description information, and description information for supporting a legacy browser.

FIG. 6A illustrates an example of a scene configured in a browser supporting a markup configured in a multimedia communication system according to an embodiment of the present disclosure.

Referring to FIG. 6A, when the markup configured according to the embodiment of the present disclosure is used, a browser supporting a new element and attribute can show all functions related to scene switching and temporal and spatial composition. Further, a browser supporting the markup configured according to the embodiment of the present disclosure, that is, an extensible markup, can change space description when an event related to provision of a space description of the multimedia element is generated or after a certain time passes.

FIG. 6B illustrates an example of a scene configured in a browser supporting only HTML in a multimedia communication system according to an embodiment of the present disclosure.

Referring to FIG. 6B, the browser supporting only the HTML can show only a minimum amount of the scene description information. That is, a browser which cannot support the extensible markup can provide only the scene description information.

FIG. 7 is a flowchart illustrating a process in which a display device spatially configures a scene based on a markup configured in the multimedia communication system according to an embodiment of the present disclosure.

Referring to FIG. 7, the display device reads scene composition information of the markup at operation 700 and acquires width and height information of areas included in the scene at operation 702. When the scene composition information is implemented as a separate document, the width and height information of the area are acquired from the separate document. At operation 704, the display device configures entire scenes including areas configured according to the width and height information acquired at operation 702.

The display device reads area description information of the markup at operation 706 and reads a division (hereinafter, referred to as “div”) reference identifier at operation 708. The display device loads a div element at operation 710 and acquires width and height information of the div element at operation 712.

At operation 714, the display device determines whether the width and height of the area acquired at operation 702 are larger than or equal to the width and height of the div element. When the width and height of the area are larger than or equal to the width and height of the div element as a result of the determination, the display device reduces the width and height of the area to match the width and height of the div element at operation 716 and proceeds to operation 720.

However, when the width and height of the area are smaller than the width and height of the div element as a result of the determination, the display device enlarges the width and height of the area to match the width and height of the div element at operation 718 and proceeds to operation 720. The display device configures the area according to the reduced or enlarged width and height of the div element at operation 720 and proceeds to operation 722.

The display device reads multimedia description information at operation 722 and acquires width and height information of the multimedia at operation 724. At operation 726, the display device determines whether the width and height of the multimedia acquired at operation 724 are larger than or equal to the width and height of the area configured at operation 720. When the width and height of the multimedia are larger than or equal to the width and height of the area as a result of the determination, the display device reduces the width and height of the multimedia to match the width and height of the area at operation 728.

However, when the width and height of the multimedia are smaller than the width and height of the area as a result of the determination, the display device completes the scene composition through the spatial description of the scene at operation 730.

FIG. 8A is a flowchart illustrating a process in which a display device temporally configures a scene based on the markup configured in the multimedia communication system according to the first embodiment of the present disclosure. In FIG. 8A, the markup configured according to the first embodiment refers to the markup configured according to the method of FIG. 4A.

Referring to FIG. 8A, the display device reads scene composition information of the markup at operation 800 and acquires time information of the scene at operation 802. At operation 804, the display device temporally configures the entire scene according to the time information of the scene acquired at operation 802.

The display device reads area description information of the markup at operation 806 and acquires time information of each area included in the entire scene at operation 808. The display device temporally configures each area according to the time information of each area acquired at operation 808 at operation 810 and reads a div reference identifier at operation 812.

The display device loads the div element at operation 814 and acquires time information of each multimedia at operation 816. At operation 818, the display device temporally configures each multimedia according to the time information of each multimedia acquired at operation 816 to complete the scene composition.

FIG. 8B is a flowchart illustrating a process in which a display device temporally configures a scene based on the markup configured in the multimedia communication system according to the second embodiment of the present disclosure. In FIG. 8B, the markup configured according to the second embodiment refers to the markup configured according to the method of FIG. 4B.

Referring to FIG. 8B, the display device reads scene composition information of the markup at operation 850 and acquires time information of the scene at operation 852. At operation 854, the display device temporally configures the entire scene according to the time information of the scene acquired at operation 852.

The display device reads area description information of the markup at operation 856 and acquires time information of each area included in the entire scene at operation 858. The display device temporally configures, at operation 860, each area according to the time information of each area acquired at operation 858 and reads a div reference identifier at operation 862.

The display device loads the div element at operation 864 and acquires identifier information of the multimedia at operation 866. The display device reads time information of the multimedia from the time information of the multimedia of the separately provided markup document and detects time information which matches the identifier of the multimedia at operation 868. At operation 890, the display device acquires the same information as the time information of the multimedia acquired at operation 816 by reflecting the detected time information in the multimedia. Thereafter, the display device temporally configures each multimedia at operation 892 to complete the scene composition.

As described above, operations 850 to 864 are substantially the same as operations 800 to 814 of the first embodiment, and only operations 866 to 890 are different from operation 816 of the first embodiment.

FIG. 9 illustrates an example of configuring a scene according to a markup configured in a multimedia communication system according to an embodiment of the present disclosure. In FIG. 9, it is assumed that the scene consists of three areas and area 3 is reproduced for 100 seconds and then divided into area 4 and area 5. Further, it is assumed that area 4 is immediately reproduced and area 5 is reproduced after 0.2 seconds when the reproduction of area 3 is completed.

Referring to FIG. 9, scene 1 consists of area 1, area 2, and area 3, where area 1 reproduces a video and audio, area 2 reproduces information in text form, and area 3 reproduces an advertisement image. After the advertisement image of area 3 is reproduced for 100 seconds, the scene is switched and thus area 4 reproduces the advertisement image and area 5 reproduces information in the text form after 0.2 seconds.

An example code of the markup for configuring the scene of FIG. 9 may be shown in Table 6.
