Conversion Mechanism for MPEG-4 Contents Services on Web Environment

Abstract

This paper is on the design and development of a conversion mechanism for MPEG-4 contents services on Web environment. The service was provided on Web environment first by parsing the MPEG-4 contents, then converting them to SMIL. After the two-dimensional profile of the MPEG-4 XMT and SMIL schemes was analyzed, the correlation among the nodes with the same or similar meanings was set as a rule. With the defined rule, an XSL document was created, and XMT was converted to SMIL using the converted XSL document and XSLT, which was derived from MSXML. Moreover, the two-dimensional geometric object that cannot be expressed in SMIL was authored in SVG to add SMIL media characters. Its advantage is that it services current MPEG-4 contents in various environments such as the Web or mobile environments, and it can be converted to service more playable environments if one knows the syntax definition of other scene description languages.
