A rich-media service is a dynamic and interactive presentation comprising 2D vector graphics, images, text and audiovisual material.
The LASeR standard fulfills these requirements by building upon the existing Scalable Vector Graphics (SVG) format defined by the World Wide Web Consortium and particularly on its Tiny profile already adopted in the mobile industry.
These key extensions permit among others: the frame-accurate synchronization of the scene with the audio-visual elements, the streaming and efficient compression of SVG content.
Efficient compression improves delivery and decoding times, as well as storage size and is achieved by a compact binary representation of the SVG scene tree.
The delivery of Rich Media content to constraint devices is a challenging task which consists in delivering the representation of the presentation along with all the audiovisual material used in it.
