HTML and XML mainly focused on creating structured documents that can be
delivered in the Web environment. Therefore, they do not consider well the
following issues:
•
Line Assignment: Which portion of the content should be presented by
what character?
•
Synchronized Presentation: Which information should be presented
simultaneously?
•
Presentation Styles: Which style should be applied to represent the content?
Indeed, as a special type of structured documents, TV scripts or movie scripts have
been traditionally treating the above issues. But, once those materials are represented
as Web pages, they become sole textual data, and they have no effective browsing
tool to express the above issues. In summary, the present HTML is not designed to
describe TV scripts or movie scripts, but to describe ordinary documents.
Therefore, we have been developing a new markup language called Scripting-
XML (abbreviated by S-XML) that is a collection of XML tags for describing
scripts as Web pages. Scripts written in S-XML are automatically translated into
TVML scripts, and can be played by the TVML player. In designing our S-XML,
we separated the
content-related tags
from
style-related tags
. This is because we
wish to allow the possibilities that scripts might be presented in more than one
styles. Also, we wish the possibilities of the usage of those scripts as ordinary Web
documents. By this separation, the content-related tags mainly specify which portion
are used in the TV-like presentation. The style-related tags mainly specify how the
specified content should be presented.
Figure 8 shows an example script written in S-XML. This script tries to introduce
Web pages containing memorial photos with comments. The author specifies to
present the content in a variety program metaphor. Two characters called BOB
and MARY are used to present the content. The script mainly consists of four
parts called
introduction, development, turnstory
and
conclusion
.
When the part changes, for example, when the part moves from the introduction
part to development part, the camera work and characters' movement try to express
the change of the parts by atmosphere. The readers will find the attribute called
imgnum
and
refimgnum
, which appear in the tags
img
and
line
, respectively.
The attribute imgnum denotes the image number, by which the attribute
refimgnum
of the
line
tag denotes that the designated image should be showed
in a synchronized manner with the speech of the line.
