At the beginning of LASeR come the frustration of key players of 3GPP, MPEG and OMA trying to implement MPEG-4 BIFS (Binary Format for Scene) as well as (SVG+DOM+CSS+EcmastScript) to extend the rich media capabilities of mobile devices. These companies came to the conclusion that it was not possible to fully satisfy their requirements. From this frustration came out LASeR, a new standard, based on the best concepts of existing open (SVGT1.2, MPEG4,...) as well as proprietary solutions (Macromedia Flash...).

The LASeR standardization process follows the usual MPEG Core Experiment process:
Core Experiments are periods of work between MPEG meetings, by interested parties, on a common workplan, to determine which of several proposed technologies are best, and then to determine if the proposed specification can be implemented in an interoperable way.

The two core experiments on Binarisation and on SVGTiny Alignment have been successfully completed before the Hong Kong meeting (2005).

  • Binarisation Core experiment:
    An ad-hoc encoding syntax is defined for LASeR and is compatible with BiM (defined in MPEG 7).

  • SVG Tiny alignment core experiment:
    The alignement of LASeR scene description features with SVG Tiny scene description features has been completed. Amendment 1 of LASeR is a superset of SVG Tiny 1.2. The Amendment 1 is expected to be completed after SVG Tiny 1.2 reaches PR, towards mid of 2007.

The Corrigendum Process aims at corecting bugs in MPEG specification.

For LASeR the corrigendum process is also used to ensure a compliancy with the SVGT1.2 specification that was not totally finalised before the release of the LASeRv1 specification.

The Study process.

The study process allows to evaluate technologies for further integration in the specification. It is called TUC: technologies under consideration. TUC are usually integrated at the DAM phase or potentialy during the FPDAM phase.

The Amendment process.

the amendment process can be compare as a new release of the specification. the release or version are incremental and maintain backward compliancy between releases.
