Abstract

A method by which a multimedia presentation editor for use on a (typically handheld) communication or computing terminal (10) interfaces with a user so as to allow the user to create or edit a presentation (20), including: a step (51) in which objects to be displayed successively when a slide (21) is displayed in play mode, are instead assembled by the editor one under another in a column (25 a), and objects (22) to be displayed continuously are also assembled in a (one-object-long) column (25 b); and a step (52) in which the editor displays each column (25 a-b) side-by-side, corresponding to the side-by-side arrangement of respective objects in the different columns (25 a-b) when the slide (21) is displayed in play mode, thus allowing some parts of the slide (21) to be fixed, and some parts (23 a-c) to change—the parts having columns with more than one object. Corresponding equipment is also provided.

TECHNICAL FIELD

The present invention pertains to the field of creating/editing presentations on a device with a small display. More particularly, the present invention pertains to creating presentations having content displayed/played (providing possibly text and images and sound all at the same time) based on instructions encoded using the SMIL language or a comparable XML-based language, and is especially useful for creating MMS messages using a handheld communication device, such as a cell phone.

BACKGROUND ART

The invention is related to editing/creating (as opposed to viewing) multimedia presentations on a portable device. Multimedia presentations are e.g. shown by the device itself or using an external display or communicated between mobile/cell phones or other communication terminals as a part of MMS (Multimedia Messaging Service) messages, as prescribed by 3GPP (Third Generation Partnership Program) technical specifications. (MMS, like Short Message Service (SMS), provides automatic and immediate delivery of personal messages, but allows incorporating sound, images, and other rich content, transforming it into a personalized visual and audio message.) The presentation part in MMS messages can use different formats, but Synchronized Multimedia Integration Language (SMIL, pronounced “smile”) 2.0 is the mandatory format specified by the current 3GPP Release 5 specification. The presentation part includes all media objects (content of the multimedia presentation) as one data object/assembly, describing their layout, timing and other aspects of displaying/playing the media objects on the receiving communication terminal. For example, if an MMS message contains two slides and each contains a text object and an image, the MMS message consists of MMS headers, two image objects, two text objects, and one SMIL object with information to the effect that the message consists of a sequence of two time containers and that the first time container contains parallel media objects (image and text). See FIG. 1 for an example of the structure of a presentation object in MMS.
SMIL is an Extensible Markup Language (XML)-based language. It contains building blocks called modules. The modules which are important from the point of view of the present invention are the so-called structure module, the timing and synchronization module, and the media object module. Each module includes one or more so-called elements and so-called attributes.
The most important elements of SMIL are the so-called “par” and “seq” elements. A par element groups object that should appear in parallel, temporally, in a presentation. For example, if text and an image are shown on one slide at the same time, they will be put within a single <par> . . . </par> pair in a block of SMIL code. A seq element may contain objects that are supposed to be presented to the user sequentially, one after the other, i.e. the second one will not become visible until the first has been displayed/played and is not longer being displayed/played. So the two slides from the previous example would typically be put within a <seq> . . . </seq> pair to indicate that they must be played in sequence. Also the main body element is treated as a seq element when timing is considered. These and some other elements are referred to as “time containers” in the SMIL language. The example above would be encoded as:


	<smil>
	<body>
	<par>
	<!--this is slide 1-->
	<img src=”image1.jpg”/>
	<text src=”text1.txt”/>
	</par>
	<par>
	<!--this is slide 2-->
	<img src=”image2.jpg”/>
	<text src=”text2.txt”/>
	</par>
	</body>
	</smil>

(This is a simplified encoding; an actual encoding in SMIL would include several more elements and attributes, none of which are relevant to the invention and so are omitted here for clarity.)

Although SMIL permits unlimited nesting of the time containers to create complex timing in a presentation, to ensure interoperability between different communication devices the Open Mobile Alliance (OMA) in the OMA MMS 1.1 and 1.2 specifications has limited the nesting level to two levels. The first level is the main body level and represents the entire presentation. This in turn consists of one or more par elements, which represent slides.
Even though OMA has introduced the above limitations to SMIL in order to ensure interoperability in the early days of MMS, there is no such limitation in 3GPP specifications, which define their own SMIL language profile. The 3GPP profile is slightly less powerful than the full W3C (World Wide Web Consortium) SMIL language 2.0, but regarding the nesting of the time containers it is unlimited too. The deeper nesting of the time containers allows for example making presentation “slides” less static and also allows introducing timing into a slide. For example a presentation may contain a set of slides having content that changes with time. (Thus, in a sense, with more than two levels, a slide may itself be an entire presentation/set of slides, each of which may itself be a new, further presentation/set of slides, and so on.)
MMS terminals available currently on the market are capable of editing or viewing only limited SMIL structures (in terms of time container nesting). The first (top) level of nesting represents the presentation and the second level represents slides. Media items are placed on the second level. Although some handheld terminals (such as cell/mobile phones) can play more complicated content than a two-level presentation, it is impractical today for typical cell phones or other handheld terminals to create more complicated presentations because editing a three-level timing and a two-dimensional space presentations on the typically small screen of a mobile phone or other handheld and making it usable by an average user is difficult. All handheld-hosted editors today are not intuitive or simple and are too time-consuming when used to create complex presentations.
Prior art MMS editors for handheld terminals (such as mobile phones) do not typically allow the content of a slide in a presentation to change with time. In other words, the slides created must be static (except that the media items contained in a slide may change, e.g. video clips, animated .GIF images, etc.). Other, more sophisticated MMS editors e.g. for desktop computers as opposed to handheld devices use an approach in which the entire presentation or animation (if the software is for video editing) is divided into “frames” displayed side-by-side in columns and rows, FIG. 3 showing one row, and a user can navigate between frames (in other words, move to a different point in the presentation) using some sort of a slider widget. An approach using frames displayed side-by-side is useful for computers with big screens, so that the software can reasonably display frames side-by-side all on the same screen. But doing so is not practical on a handheld device because of the small size of the screen.
What is therefore needed is a way of providing instructions for creating a complex multimedia message such as an MMS message on a handheld device, i.e. e.g. a multimedia message that is more than two levels.

FIG. 5 is a flowchart illustrating a method according to the invention by which an editor hosted e.g. by a handheld device having a small screen enables a user to create a slide for a presentation.

BEST MODE FOR CARRYING OUT THE INVENTION

The invention provides a hybrid solution for how to create complex multimedia presentations on a handheld device, taking what is appropriate from the various existing solutions so as to provide increased editing capability on a handheld, editing that is intuitive and relatively fast.
Referring now to FIG. 2, in editing a presentation 20 using an editor according to the invention, the parts of a slide 21 that change (i.e. typically the images, in that the images in a set of images 23 a-c are to be shown when played one at a time and one after the other, but on the same slide 21) are shown like “frames” are shown by editors for desktop computers, i.e. next to each other (more specifically, one on top of the other, as shown in FIG. 2). But the parts of the slide 21 that are static—usually the text 22 for a slide—are shown only once, i.e. are not repeated for each part (usually an image) that changes. Such a hybrid solution saves space on the screen.
The proposed solution assumes that the layout rules—i.e. e.g. the SMIL for the presentation—are fixed and that the part of a slide that does not change (typically the text) is fixed for the duration of a slide. For example, it is reasonable to suppose that a user might take three pictures with a built-in camera and might want to show the pictures in sequence in a presentation. At the same time the user might want a block of text to appear with all of the picture, such as e.g., “These are the pictures I took in front of my house.” This is a likely use case because typing long text on a small device like a mobile phone (especially if it does not have a full “qwerty” keyboard) is time-consuming and so a user would likely not want to input a lot of different text blocks, whereas taking pictures is easy to do and fast. Also, it is unlikely that a user would want to manipulate the layout of a slide for a presentation on a handheld device because on a small screen there is not enough space for any (significant) manipulation.
Using these assumptions, as explained above, the solution provided by the invention is to display images one under another (not overlapping, but arranged in a column) in the presentation editor—i.e. in edit mode—with instructions for play mode (provided e.g. using SMIL) that the images be displayed in a temporal sequence, one after the other. At the same time the horizontal layout remains true, i.e. corresponds to the layout seen when the presentation is played. Thus, the vertical layout in the editor does not correspond to the actual layout seen when the presentation is played: the vertical dimension in the editor represents time.
Referring now to FIG. 4A, a display device 10 a of a communications or computing terminal 10 for an exemplary slide 21 is shown when the slide 21 is displayed by an editor according to the invention. The slide 21 includes two pictures 23 a-b and accompanying text block 22, and so in edit mode the screen is as shown in FIG. 4A, with the two pictures 23 a-b arranged in a vertical column (of two rows) and appearing on the screen at the same time, and the text block 22 appearing as the one and only row of another vertical column. The corresponding screen in play mode for the slide would show the two pictures 23 a-b one after the other in time (i.e. not at the same time), with the (same) text block 22 displayed for each. The instructions for so playing the slide (i.e. for displaying it in play mode) are included e.g. in an SMIL object (not shown) included with the image objects 23 a-b and text object 22 in e.g. an MMS message. Note that if the text were longer, or if there were more images in the first column, the display device 10 a would provide scroll controls typically on the right hand side so as to allow viewing all the text.
The SMIL, in simplified form, corresponding to the editor screen of FIG. 4A—i.e. indicated by the editor screen of FIG. 4A as how the presentation is to be played, can be (more or less) as follows:


<smil>
<body>
<par>
<!--this is slide 1-->
<seq>
<img src=“image1.jpg” dur=“10000ms”/>
<img src=“image2.jpg” dur=“10000ms”/>
</seq>
<text src=“text1.txt”/>
</par>
...
</body>
</smil>

(The “more or less” is because, as in the earlier exemplary SMIL code fragment, the SMIL code fragment here is also simplified encoding; an actual encoding in SMIL would include several more elements and attributes, none of which are relevant to the invention and so are omitted here for clarity.) To specify a presentation including both the slide(s) corresponding to the editor view of FIG. 4A and also another slide (or slides, depending on how you count) in which the same text is repeated for three different images, the SMIL code fragment would be something like:


<smil>
<body>
<par>
<!--this is slide 1-->
<seq>
<img src=“image1.jpg” dur=“10000ms”/>
<img src=“image2.jpg” dur=“10000ms”/>
</seq>
<text src=“text1.txt”/>
</par>
<par>
<!--this is slide 2-->
<seq>
<img src=“image3.jpg” dur=“10000ms”/>
<img src=“image4.jpg” dur=“10000ms”/>
<img src=“image5.jpg” dur=“10000ms”/>
</seq>
<text src=“text2.txt”/>
</par>
</body>
</smil>

As can be seen from the above SMIL code fragments, the invention allows creating a slide that is described by more than two (and in fact here three) levels of time containers in SMIL (as opposed to three levels of SMIL).
Referring now to FIG. 4B, the two screens in play mode corresponding to the single editor screen (which, depending on the display device 10 a, may not be visible all at once, and so may require scrolling) displayed in FIG. 4A are shown on a display device that may be the display device 10 a of the communications or computing terminal 10 on which the exemplary slide 21 was created using an editor according to the invention (as is indicated in FIG. 4B), or that may be any other display device (not necessarily communicatively coupled to the communications or computing terminal 10). As indicated by the above code fragment for slide 1, in play mode, while slide 1 is being displayed, first image 1 is shown and then, after about 10 seconds, image 2 is shown, i.e. on the same slide.
Note that in some embodiments, to generate the SMIL (or comparable) code, the user using the editor would click on or otherwise signal the editor that the user would like to prescribe properties for an image being displayed in edit mode, and the user would then be presented with a dialog box in which the user is able to indicate e.g. the duration the image is to be displayed. The SMIL code can then be generated automatically based on the properties ascribed to each image and the arrangement of objects on the editor screen. Also, if a duration is not provided for the images, the editor can be configured to generate the SMIL code assuming a default duration for a slide and dividing the default duration for the slide into time segments of the same duration for each image. Alternatively, in some embodiments, a user can be presented with a text editor by which the user can provide the SMIL code for a slide, referring to images either based on names associated with each and included in the respective properties of the images, or based on the order in which the images appear on the screen in edit mode.
An advantage of the solution provided by the invention—at least in comparison to the frame-based approach of the prior art—is that it saves screen space and, in addition, has a more familiar look-and-feel for users already used to slide-based editors provided for use on desktop computers. To save screen space though, an editor according to the invention does not show the actual vertical alignment of the text versus image (i.e. as it is seen in playing the presentation); the user of the editor must preview the presentation in player mode to see the actual vertical alignment.
Referring now to FIG. 5 (and also to FIGS. 2 and 4), the invention is shown as a method by which a multimedia presentation editor hosted by the communication or computing terminal 10 having the display device (screen) 10 a, interfaces with a user so as to allow the user to create or edit the presentation 20 including a slide 21 that in turn includes a plurality of objects such as the text object 22 and the image objects 23 a-c for display (and also objects 24 for providing audible components of the presentation), the method including: a step 51 in which the displayable objects 22 23 a-c in each set of (typically image) objects of the slide 21 that are to be displayed sequentially (one after the other in time) in play mode are instead assembled by the editor in multi-object columns 25 b, i.e. one under another, and the objects that are to be displayed continuously are assembled into one-object-long columns 25 a; and a step 52 in which each column 25 a-b is displayed side-by-side with each other column 25 a-b. Thus, if a column includes only a single object, that object is a fixed element of the slide, i.e. it appears for the entire time the slide is displayed in play mode. On the other hand, in case of a column including more than one object, each object is displayed for only some of the time the slide is displayed in play mode. In other words, the displayable objects 22 23 a-c of the slide 21 form on the display device 10 a in edit mode one or more side-by-side vertical columns 25 a-b some of which may include only a single object 22 and some of which may include more than one object 23 a-c, thus providing that some parts of the slide 20 may remain fixed (the part with the text object 22 in the illustration of FIG. 2) while the slide is displayed in play mode and some parts may change (the part with the image objects 23 a-b in the illustration of FIG. 2).
Although the invention has been shown and described in the case of unchanging text 22 and changing images 23 a-c of a slide 21, so that in edit mode there are two side-by-side columns, it is also within the scope of the invention that there be more than two columns, and even that none of the columns include a single object. For example, a first column might include two objects, a second column three, and a third column four. In such a case, the timing relationships between the objects in the three columns can be specified by e.g. SMIL, or can even be automatically figure by a play device, based on the smallest number evenly divisible by the numbers of objects in each of the columns, in this case 12. An automatic determination of the timing relationship in this case would provide that each object in a column be displayed for a time proportional to the ratio of the smallest number evenly divisible by the numbers of objects in each of the columns to (divided by) the number of objects in the subject column.
The invention has been described in terms (primarily) of the steps of a method. The invention also comprehends an apparatus for performing the above described steps. Thus, for each step described above, there can be a corresponding module of an apparatus, although it is also possible for the functionality for performing more than one of the above-described steps to be incorporated into a single module. Such modules may be implemented as hardware, or may be implemented as software or firmware for execution by a processor. In particular, in the case of firmware or software, the invention is provided as a computer program product including a computer readable storage structure embodying computer program code—i.e. the software or firmware—thereon for execution by a computer processor provided with the communication or computing terminal 10.
It is important to understand that the invention is especially of use in creating presentations in any situation in which a small screen/display is used, such as in handheld communication or computing terminals including e.g. digital cameras, personal digital assistants (PDAs) and so on, i.e. in any device hosting a microprocessor enabling a user of the device to manipulate images on a display. Thus, the invention is not restricted to creating presentations that are communicated, as e.g. an MMS message; the invention pertains only to the creating of a presentation. The presentation may be played by the same device or by another device, one not even necessarily having a small screen. Moreover the presentation need not be telecommunicated to the other device, i.e. communicated over a wireline or wireless telecommunication network(s); the presentation can be created using e.g. a cell phone and then shown e.g. via an external display such as a TV or other video display device. Further, the invention can be used to create different kinds of presentations, including presentations compatible with Microsoft Powerpoint.
It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the scope of the present invention, and the appended claims are intended to cover such modifications and arrangements.
