- 요약
- ISO/IEC 14496-20:2006 defines a scene description format (LASeR) and an aggregation format (SAF) suitable for representing and delivering rich-media services to resource-constrained devices such as mobile phones. A rich media service is a dynamic, interactive collection of multimedia data such as audio, video, graphics, and text. Services range from movies enriched with vector graphic overlays and interactivity (possibly enhanced with closed captions) to complex multi-step services with fluid interaction and different media types at each step.
