Members of the MPEG-4 Audio Licensing Committee have announced the selection of Via Licensing Corporation as the Licensing Administrator for the MPEG 4 Audio patent pool. This development will hasten the availability of standard licensing agreements for patents essential to MPEG-4 Audio technologies. MPEG Audio technologies are familiar to users around the world. MPEG-1 Layer 3, otherwise known as MP3, provides an excellent example of the value of an open and interoperable standard in the creation of new applications and markets. The most recent MPEG standard, MPEG-4, doesn't define a single audio coding scheme, but rather a rich set of technologies addressing a range of different applications and covering a spectrum of bit-rate, scalability, and audio quality requirements. The goal of the MPEG-4 Audio Licensing Committee is to provide one-stop access to patents from multiple parties that are necessary for the practice of MPEG-4 Audio under fair, reasonable, and nondiscriminatory conditions. The MPEG-4 Audio standard is organized so that various audio tools, or coding approaches, are assembled into Audio Objects that are further combined into multiple MPEG-4 Audio Profiles. The work of the MPEG-4 Audio Licensing Committee was initiated by the MPEG-4 Industry Forum (M4IF) with a request that patent holders develop licensing terms for three MPEG-4 Audio Profiles: the High Quality Audio Profile, the Speech Audio Profile, and the Mobile Audio Internetworking ("MAUI") Profile. In addition to these three profiles, members of the Licensing Committee are working with Via Licensing Corporation to create essential patent license agreements for those Audio Objects that are of interest to the market on a stand-alone basis. The specific technologies comprising the MPEG-4 Audio Profiles to be covered by the initial licenses are:

--  Speech Audio Profile--CELP, HVXC, TTSI

--  High Quality Audio Profile--AAC LC, AAC LTP, AAC Scalable,


--  Mobile Audio Internetworking Profile--ER AAC LC, ER AAC

-- Scalable, ER TwinVQ, ER BSAC, ER AAC LD

The Licensing Committee expects to deliver MPEG-4 Audio Profile license agreements in the first quarter of 2003.
