ISO/IEC 14496-20:2008 defines a scene description format (LASeR) and an aggregation format (SAF) respectively suitable for representing and delivering rich-media services to resource-constrained devices such as mobile phones.
LASeR aims at fulfilling all the requirements of rich-media services at the scene description level. LASeR supports:
Technology selection criteria for LASeR included compression efficiency, but also code and memory footprint and performance. Other aims included: scalability, adaptability to the user context, extensibility of the format, ability to define small profiles, feasibility of a J2ME implementation, error resilience and safety of implementations.
SAF aims at fulfilling all the requirements of rich-media services at the interface between media/scene description and existing transport protocols:
SAF has been designed to complement LASeR for simple, interactive services, bringing:
ISO/IEC 14496-20:2008 defines the usage of SAF for LASeR content; however, LASeR can be used independently from SAF.
