MPEG-1, MPEG-2, MPEG-4, H.261, H.263, H.264, MP3, DV, VC-1, MJPEG, AC3, and AAC are international standards promoted
by ISO, IEC, ITU, ETSI and other organizations. Implementations of these standards, or the standard enabled platforms may
require licenses from various entities, including Intel Corporation.
