MPEG-2 Systems Patents ReviewISO/IEC 13818 Rob Glidden, December 2011
Disclaimer • Information provided to facilitate consideration of Type-1 / royalty-free MPEG standardization* • Not to be used as legal advice • Not represented as comprehensive • Only public sources considered • Corrections, additions & comments welcome * See N12204, Call for Proposals (CfP) for Internet Video Coding Technologies, ISO/IEC JTC1/SC29/WG11, July 2011, Torino, Italyhttp://mpeg.chiariglione.org/working_documents/explorations/ivc/ivc-cfp.zip
Motivation • MPEG Systems IPR provides an informative process template for video coding IPR review • Commonalities to any RF video coding proposal • Patents claimed on both MPEG LA video & systems (inc. US 5291486, 5796743, 5289276, 5268846, 4970590) • Pool list updated regularly since 1996 • A royalty-free codec like MPEG IVC will likely need the availability of a royalty-free systems layer
Systems Patents in Context* • 17% (23) of MPEG-2 patents • 29% (10) of unexpired patents after July 2013 Systemspatents * See “MPEG-2 Patent List”, December, 2011 “MPEG-2 Patents”, December, 2011
Review Methodology IPR Mapping Capabilities UnexpiredPatents ExpiredPatents Type-1 (RF)LicensedPatents Unpatented Prior Art
Conclusion • 10 systems patents will remain unexpired as of July 31, 2013 • Several seem clearly feature-specific • A royalty-free codec like MPEG IVC will likely need the availability of a royalty-free systems layer • MPEG should consider specifying a royalty-free systems profile
