MPEG MPEG-1 The start of the evolutionary process. MPEG-2 has become the coding standard for DAB and DVB, which are both used worldwide. MPEG-4 is likely to become a universal coding system for all delivery systems, including television and radio broadcasting, telecommunications and the Internet. MPEG-4 may be seen as a complementary system, which could carry some ancillary services such as video clips, games, 3D graphics, etc., which are embedded in the main MPEG-2 transport stream. New profiles are being added to MPEG-4, such as ITU-T codec H26L. Furthermore, the MPEG family is being extended by new “MPEG-X” members. For example, MPEG-7 is dealing with metadata and content descriptions. MPEG-21 deals with content management. In the Internet environment, MPEG-4 is likely to become a viable commercial proposition. Being an open source system, it may be able to supersede – in the mid term – the existing market leaders which dominate the Internet markets by using their proprietary systems such as Windows Media 8, RealNetworks 8 and QuickTime (Sorenson 3) The MPEG Handbook – MPEG-1, MPEG-2, MPEG-4 MPEG bit ate transcoding - (PDF) Tomcast white paper EBU Technical Review - (PDF) EBU / SMPTE Task Force for Harmonized Standards for the Exchange of Programme Material as Bitstreams |
