Description

Method and device for setting framework of SMIL message

The present invention relates to a SMIL message, and more particularly, to a method and apparatus for setting a SMIL framework for a synchronous multimedia integrated language message in a mobile communication system.

Synchronized Multimedia Integration Language (hereinafter referred to as "SMIL") is one of the multimedia message expression methods for expressing multimedia objects such as images, sounds, videos, and the like in a temporal and spatial combination.

With the rapid development of the Internet and PC environment, it is possible to express multimedia objects, and SMIL based on Extensible Markup Language (XML) in the World Wide Web Consortium (W3C) to express various multimedia objects effectively. Defines a message expression convention.

With the development of information and communication technology, mobile communication terminals have also been rapidly developed and / or spread along with the Internet and PCs. In addition, recent mobile communication terminals are capable of processing and transmitting various multimedia objects such as images, sounds, and videos as well as transmitting and receiving simple voice messages or short messages.

The initial Multimedia Message Service (MMS) using a mobile terminal was implemented by simply attaching a multimedia object to an existing text message. Since these early MMSs were to transmit simple combinations of multimedia objects, HyperText Markup Language (HyperText Markup Language) based on HyperText Transfer Protocol (HTTP), which is a multimedia object representation generally used on the wired Internet; HTML, XML, etc. is used.

Recently, as the user's demand for the multimedia message using the mobile communication terminal increases and the mobile communication terminal also develops to the performance sufficient to satisfy the user's demand, the MMS standard, which is a standard for transmitting and receiving multimedia messages, has been enacted. SMIL is adopted as one of the MMS expressions. Here, the SMIL message is not composed of simple combinations of objects, but in a form that defines the temporal and spatial arrangement of the objects.

Accordingly, the SMIL message is classified and transmitted according to a method of simplifying a complicated method of composing the SMIL message in various mobile communication terminals, and whether the receiving terminal supports the SMIL message and the processing capability of the SMIL message. Consideration was given to the way of doing so.

In the prior art of the method for creating a SMIL message, a method for providing a SMIL framework including predetermined temporal and spatial arrangement information to a user has been proposed. According to the proposed technique, the user can easily write a SMIL message having a relatively diverse effect by including a desired multimedia object and text in the provided SMIL framework.

However, when a SMIL message is generated by selecting a SMIL template whose background color is set to black, the background color of the SMIL message and the color of the text are generally different because the default color of the text of the other terminal is set to black. There was a problem that all of them are displayed in black and the transmitted SMIL messages cannot be read.

The present invention is directed to providing a method and apparatus capable of establishing a template (i.e., SMIL message framework) for a synchronous multimedia integrated language message.

In addition, the present invention is to provide a method and apparatus for setting a template for a synchronous multimedia integrated language message that can automatically set the basic color of the text in a color contrasted with the background color of the SMIL message framework.

According to an aspect of the present invention, a method for setting a SMIL framework for the creation of a synchronous multimedia integrated message in a mobile communication terminal is provided.

According to an embodiment of the present invention, a method for setting a SMIL framework for creating a synchronous multimedia integrated message in a mobile communication terminal, the method comprising: receiving any one of the stored SMIL frameworks; Setting background color information of the selected SMIL framework; And setting basic color information of the text object of the selected SMIL framework using the set background color information.

According to another aspect of the present invention, an apparatus for setting a smile template for creating a synchronous multimedia integrated message is provided.

According to an embodiment of the present invention, an apparatus for setting a SMIL framework for creating a synchronous multimedia integrated message, the apparatus comprising: a storage unit for storing one or more SMIL frameworks and a preset color information table; An input unit to receive one of the stored SMIL frameworks; And a controller configured to set background color information of the selected SMIL framework and to set basic color information of a text object of the selected SMIL framework using the set background color information. Can be.

By providing a method and apparatus for setting a template for a synchronous multimedia unified language message according to the present invention, there is an effect of setting a template (SMIL message framework) for a synchronous multimedia unified language message.

In addition, the present invention has a problem that the other terminal can not read the content of the message because the background color and the text color of the SMIL message is the same by automatically setting the base color of the text in a color contrasted with the background color of the SMIL message framework There is an effect that can prevent in advance the user's mistake caused.

Referring to FIG. 1, a general SMIL message includes a SMIL body body object, a text object including text, and a media object such as an image, a video, an audio diagram, and the like. Each entity included in the SMIL message is separated into a boundary line, and may include a header field of each entity.

The SMIL body body object is an object that forms the basic framework of the SMIL message, in which the filename of the multimedia object to be shown in the message is defined and the temporal and spatial arrangement of each multimedia object is defined. Here, the SMIL body body object includes various SMIL tags in order to show a message using a real text object and a media object, and the temporal and spatial position of text and each media through an XML-based SMIL tag. Express

A text object is an object containing text input by a user. The text object may be expressed using a standard HTML, plain, or eXtensible Hypertext Markup Language (XHTML).

A media object is an object that defines information and content about media such as actual images, videos, and audio shown at temporal and spatial positions defined in SMIL body bodies.

2A, 2B and 2C are exemplary diagrams illustrating an example of a general SMIL message according to an embodiment of the present invention.

As described above in the description of FIG. 1, the SMIL message may be composed of a SMIL body body object 210, a text object 220, and a media object 230.

Here, the SMIL body body object defines an ID that uniquely identifies an element within a SMIL document. For example, "Message.htm" 20 defined in SMIL body body object 210 is defined as 'region = "text"' in conjunction with content-ID Message.htm 21 of text object 220. A text object whose Content-ID is defined as Message.htm (20) in the spatial domain is shown in the SMIL message. Within an SMIL message, each entity can be defined in this way.

4 is a flowchart illustrating a process of creating a SMIL message in a terminal providing a SMIL framework according to the prior art.

Referring to FIG. 4, first, in step S410, a medium to be attached to an SMIL message is selected by the terminal. Step S410 may be performed by selecting / inputting a media to be attached to the SMIL message from the displayed multimedia content list when the terminal is operated to display a multimedia content selection screen such as an image, a video, or an audio. Here, step S410 may be inserted after the SMIL message framework is selected or after text to be transmitted is input.

Next, a step S420 of inputting a message, that is, text to be transmitted together with the multimedia content through the SMIL message is performed in the terminal. Step S420 may also not necessarily be performed after step S410 or prior to SMIL framework selection.

Next, an operation of selecting a SMIL framework to which multimedia content and text to be transmitted from a terminal is attached (S430) is performed. In this case, when the SMIL framework is selected, a menu for previewing the temporal and spatial effects of media and text in the SMIL framework to be selected may be added.

As described above, steps S410, S420, and S430 may be performed regardless of the order.

Next, a step (S 440) is performed to confirm that the media and the input text selected in the previous step are applied to the SMIL framework selected in the previous step.

Finally, the SMIL message creation is completed by operating a menu for completing SMIL message creation in the terminal (S450).

According to the related art, a unique ID is assigned to each of the above-described SMIL frameworks so that each SMIL framework can be easily managed.

5A, 5B, 5C, 5D and 6A, 6B, and 6C are exemplary views illustrating basic color information of a text entity in a SMIL message according to an embodiment of the present invention.

In this specification, for convenience of understanding and description, a unique ID of the SMIL framework is referred to as SMIL_Theme_ID, and basic color information (hereinafter, referred to as "text basic color information") of a text object in the SMIL framework is referred to as Default_TextColor. It will be called.

5A, 5B, 5C, and 5D, as shown in FIG. 3, the SMIL message is sent to the service parameter entity 510, SMIL body body entity 520, text entity 530, and media entity 540. Can be configured.

Here, SMIL_Theme_ID may be included in the service parameter entity 510 as shown in the figure. The text basic color information 550 of the SMIL framework may be included in any one of the service parameter entity 510, the SMIL body body entity 520, or the text entity 530.

6A, 6B, and 6C, as shown in FIG. 1, a SMIL message may be composed of a SMIL body body object 610, a text object 620, and a media object 630. Here, SMIL_Theme_ID and Default_TextColor may be located in the SMIL body body object 610 as described above. Of course, Default_TextColor may be located in the text object 630. 6A-6C, text basic color information 640, 650 for the text object 630 is included in the SMIL body body object 610. So far, I have outlined the general composition of SMIL messages and how to provide SMIL framework, SMIL framework ID, and text basic color information.

7 is a block diagram illustrating an internal function of a user terminal capable of composing an SMIL message according to an embodiment of the present invention. Hereinafter, the user terminal 700 is a device that receives a mobile communication service provided by a mobile service provider through a communication network, and includes a mobile communication network such as personal digital assistants (PDAs), notebook computers, computers, and the like. If the device can use a variety of services through it can be applied without limitation.

Referring to FIG. 7, the user terminal 700 according to the present invention includes a transceiver 710, an input unit 715, a display unit 720, a storage unit 725, an audio input unit 730, and an audio output unit 735. ) And a control unit 745.

The transceiver 710 performs a function of transmitting and receiving various data such as voice and video with a wirelessly connected mobile communication network when the user terminal 700 operates in a communication mode for performing communication. In addition, the transceiver 710 may include a transmitter for amplifying the frequency of the transmitted signal and a receiver for amplifying the received signal and adjusting the frequency. In addition, the transceiver 710 may further include a modem for modulating and demodulating the signal to be transmitted and received.

The input unit 715 generates various signals corresponding to a user's manipulation and outputs the signals to the controller 740. For example, the input unit 715 is a means for receiving a control command for controlling the operation of the user terminal 100, a control command for executing an arbitrary application, and the like from the user. The input unit 715 is implemented by a plurality of key buttons (for example, numeric / character keys, * or # symbol keys, and one or more function keys (for example, menu keys, call keys, confirmation keys, application execution keys, etc.). In addition, the input unit 715 may include a command for selecting a SMIL framework for inputting a random SMIL message, inputting various text information, a command for selecting information on a media object, and the like. Can be input.

The display unit 720 displays the data processed by the control of the control unit 740 as time information. For example, the display unit 720 is a means for displaying a SMIL message framework, a SMIL message in preparation, or a SMIL message in advance, which are stored in advance under the control of the controller 740. In addition, the display unit 720 may be an LCD or a plasma display panel (PDP).

The storage unit 725 stores a SMIL framework for one or more preset SMIL messages and one or more media objects (eg, image objects, text objects, video objects, audio objects). As described above, the SMIL framework is a group of temporal and spatial event attributes defined for composing an SMIL message, so that the actual media object and text object are not inserted. Thus, the SMIL framework itself is not meaningful as a SMIL message, and must be attached to any media object and text object to have a meaning as a SMIL message. In addition, the SMIL framework may be mapped and stored in preset identification information (eg, SMIL_Theme_ID).

In addition, the storage unit 725 is an operation program for operating the user terminal 700 according to the present invention, data (characters, numbers, images, etc.) input through an external input device (for example, a 24-pin data input / output terminal, etc.). , Video, audio).

The sound input unit 730 starts and ends operation under the control of the controller 740 and is a means for receiving an analog voice signal from the outside. For example, the sound input unit 730 may be a microphone.

The sound output unit 735 outputs audio stored in the storage unit 725 or received through a communication network under the control of the controller 740. In addition, the sound output unit 735 may include a sound source chip (for example, a Yamaha sound source chip), a speaker, and the like.

The controller 740 is an internal component of the user terminal 100 according to the present invention (for example, the transceiver 710, the input unit 715, the display unit 720, the storage unit 725, the sound input unit 730). ), The sound output unit 735, and the like.

In addition, the control unit 740 receives an arbitrary SMIL framework from the user through the input unit 715, and selects or inputs one or more media objects and text objects to be included in the SMIL framework (ie, to be attached). Can generate SMIL messages. In addition, the controller 740 may transmit the generated SMIL message to the counterpart terminal (not shown) through the transceiver 710.

In addition, when the background color information of the SMIL framework selected by the user is set, the controller 740 may set text basic color information (eg, Default_TextColor) of the SMIL framework as a color that contrasts with the background color information. have.

For example, suppose the user is composing any multimedia message (MMS). In this state, assume that one of the predetermined SMIL frameworks is selected. The control unit 740 attaches each object (eg, text object, media object) included in the multimedia message MMS being prepared by the preset method to the selected SMIL framework. When the background color information is set in the SMIL framework, the controller 740 may set basic color information of the text to a color that is in contrast to the background color information by using a preset color information table. The controller 740 may control the text object to be output through the display unit 720 with the set basic color information.

In addition, when the user is requested to change the basic color information of the text of the SMIL framework by the user, the controller 740 determines whether the color information selected by the user is an evasive color corresponding to the background color information of the SMIL framework. do. In this specification, the avoidance color is defined as color information similar to the background color of the SMIL message. For example, if the background color of a SMIL message is yellow, the avoidance color is set to a yellow-based color, including yellow.

 For example, the controller 740 may determine whether to avoid color corresponding to each color information by using a preset color information table. That is, the controller 740 may recognize the avoiding color when the same color series as the background color information is used. For this reason, when the controller 740 recognizes that the color is avoided, the controller 740 may extract and output a preset guide message (that is, a color similar to the background color. Please select another color).

In addition, when the background color information of the SMIL framework is changed by the user, the controller 440 may change the basic color information of the text to a color contrasted with the changed background color information by using a preset color information table. .

As such, by automatically changing the basic color information of the text to a color that contrasts with the background color information of the SMIL framework, due to a user's mistake, the text is changed to a color similar to the background color information to make the text invisible. There is an advantage that can be prevented.

8 is a flowchart illustrating a method of creating a SMIL message in a user terminal according to an embodiment of the present invention. In the following description, it is assumed that a user selects one of the preset SMIL frameworks to create a SMIL message. In addition, each step described below is performed by each of the internal components of the user terminal 100, but will be collectively described as a user terminal for convenience of understanding and explanation.

In operation 810, the user terminal 700 receives a selection of one of the SMIL frameworks among preset SMIL frameworks.

In operation 815, the user terminal 700 extracts information of a media object and a text object set in the selected SMIL framework, generates and outputs a guide message according to a predetermined format.

For example, if two image objects and one text object can be attached to the SMIL framework, the user terminal 700 outputs a message indicating that two images can be selected and attached and text can be input. can do.

In operation 820, the user terminal 700 receives a media object to be attached to the selected SMIL framework and receives text (ie, a message to be transmitted).

In operation 825, the user terminal 700 determines whether basic color information of text is set in the selected SMIL framework.

If the basic color information of the text is not set, in step 830, the user terminal 700 extracts the background color information set in the selected SMIL framework and then applies the extracted background color information to the extracted background color information. Set the basic color information of the text in contrasting color. In addition, the user terminal 700 controls the text input as the basic color information of the set text to be displayed.

Here, step 830 may be performed before step 820. For example, if the text basic color information of the selected SMIL framework is not set, the user terminal 700 extracts the background color information set in the selected SMIL framework and displays the text in a color contrasted with the preset background color information. Default color information (Default_Textcolor) can be set. When text is input from the user, the user terminal 700 may control to display text input in a color corresponding to basic color information of the corresponding text.

However, if the basic color information of the text is set, the user terminal 700 controls to display the text input with the set basic color information in step 832.

In operation 835, the user terminal 700 determines whether a background color change command of the SMIL framework selected by the user is input.

If a background color change command of the selected SMIL framework is input, in step 840, the user terminal 700 receives color information to be changed from the user and changes the background color information of the selected SMIL framework as the corresponding color information. In addition, the user terminal 700 sets basic color information of the text as a color contrasted with the changed background color information by using a preset color information table.

For example, assume that the color information to be changed input by the user is "black". In this case, the user terminal 700 may change the text basic color information of the selected SMIL framework into contrasting "red". That is, the user terminal 700 may set Default_Textcolor of the selected SMIL framework to white (for example, "Default_Textcolor = red").

In operation 845, the user terminal 700 determines whether a text basic color information change command is input from the user.

If a text basic color information change command is input, in step 850, the user terminal 100 receives text color information to be changed from the user, and whether the input text color information is an avoiding color similar to the background color of the SMIL framework. To judge.

If not, the user terminal 700 sets basic color information of the text as the input text color information in step 855.

As described above, the user terminal 700 extracts a Default_Textcolor parameter in the SMIL framework and sets an attribute value of the Default_TextColor as input text color information.

However, if the avoidance color, in step 860 the user terminal 700 outputs a preset guidance message (for example, a color that can not be changed. Please choose a different color).

In operation 865, the user terminal 100 determines whether a message transmission or storage command is input from the user.

If a message transmission or storage command is input, the user terminal 700 attaches the media object and the input text selected by the user to the SMIL framework, and then generates and transmits a SMIL message using the SMIL framework. And store.

9 is a diagram illustrating a UI in which a text basic color is changed according to a background color in a SMIL framework according to an embodiment of the present invention.

As shown in FIG. 9A, for example, assume that the background color information of the SMIL framework is set to yellow. When the background color information is set to yellow, the user terminal 700 extracts a color (for example, a color having a complementary color) contrasting to yellow using a preset color information table. That is, in this case, green color contrasted with yellow may be extracted. Subsequently, the user terminal 700 may set the text basic color information parameter (eg, Default_Textcolor) of the preset SMIL framework to green.

In this state, assume that the background color of the SMIL framework is changed to green by the user. In this case, the background color of the SMIL framework and the base color of the text are both set to green. Therefore, when the user generates the final SMIL message using the SMIL framework and transmits the message to the counterpart terminal without changing the basic color of the text, the counterpart terminal can read the text included in the SMIL message sent by the user. There will be no problems.

Accordingly, the user terminal 700 according to the present invention, when the background color of the SMIL framework is changed to green in this way, even if the basic color information of the text is not changed separately by the user, the color contrasted with the changed background color (For example, yellow), the basic color information of the text may be changed (see FIG. 9B). Thus, there is an advantage that can prevent in advance a mistake that may occur by the user.

In this specification, the description is focused on assuming that the basic color of the text is changed to a color contrasted with the background color of the SMIL framework. However, depending on the implementation method, the input message may be shaded or added with a shadow to add a background color and a shadow. Naturally, it can be set to distinguish.
