Moving Object Detection from MPEG Coded Picture

A proposed method extracts moving objects from MPEG bit stream directlv. i.e. without video de" , coding process. Along with rapid progress of multimedia technology, motion picture is increasingly handled on computer these days. Accordingly the MPEG format becomes a worldwide standard, and is accepted in many fields, namely broadcasting, communication, networking and archiving. At the same time...

MPEG-21 in Broadcasting Role in the Digital Transition of Broadcasting

The transition to digital in the TV broadcasting industry is already gradually being performed while the complete digital switchover seems now possible to be accomplished within the near future. This article describes and analyses this phenomenon and the role of MPEG-21 may play in it. MPEG-21 is the ISO/IEC standard currently under development in MPEG (ISO/IEC JTC1/SC29/WG11). Unlike preceding...

Selective Encryption for Hierarchical MPEG

Selective encryption of visual data and especially MPEG has attracted a considerable number of researchers in recent years. Scalable visual formats are offering additional functionality, which is of great benefit for streaming and networking applications. The MPEG-2 and MPEG-4 standards provide a scalability profile in which a resolution scalable mode is specified. In this paper we evaluate a s...
