The paper deals with efficient compression of immersive video representations for the synthesis relatedto virtual viewports, i.e., to selected viewer positions and directions watching. Thegoal is obtain possibly high quality obtained from compressed immersivevideo acquired multiple omnidirectional planar (perspective) cameras, or computer animation. Inthe paper, we describe a solution based on ...

This paper gives an overview of Part 1 of ISO/IEC 15939 (MPEG-7 Systems). It first presents the objectives of the MPEG-7 Systems activity. In the MPEG-1 and MPEG-2 standards, “Systems” referred only to overall architecture, multiplexing, and synchronization. In MPEG-4, in addition to these issues, the Systems part encompasses interactive scene description, content description, and programmabili...

MPEG-21 is an open standards-based framework for multimedia delivery and consumption. It aims to enable the use of multimedia resources across a wide range of networks and devices. We discuss MPEG-21's parts, achievements, ongoing activities, and opportunities for new technologies. Publication Details This article was originally published as: Burnett, I, Van de Walle, R, Hill, K et al, MPEG-21 ...

This application report describes the implementation of MPEG-4 motion compensation on the Texas Instruments (TI) TMS320C62x digital signal processor (DSP). MPEG-4 is a standard for coding of audiovisual information being developed by the Motion Picture Experts Group (MPEG). MPEG-4 became an International Standard in December 1998. Motion compensation is a basic component of MPEG-4 and other vi...

The goal of this research is to prepare novel amphiphilic graft copolymers (nonionic) based on hydrophilic poly (ethylene glycol) methyl ether (mPEG) and hydrophobic methacrylate (MMA) at room temperature pressure. To generate P(mPEG-g-MMA) grafts, was synthesized grafted with varied ratios in the existence benzoyl peroxide as an initiator utilizing a macro-free radical procedure under effect h...

In 1988, the International Organization for Standardization (ISO) established the Moving Pictures Experts Group (MPEG) with the mission to develop standards for the coded representation of moving pictures and associated audio for digital storage media. The work of the MPEG group led to the development of several ISO standards, including ISO 11172, known as MPEG-1 [1]; ISO 13818, known as MPEG-2...

Authoring MPEG-4 content is quite a challenge. Far from the past one-video-plus-one-audio-streams of its predecessors MPEG-1 and MPEG-2, MPEG-4 allows the content creator to compose together spatially and temporally large numbers of objects of different types (rectangular or shaped video, still image, natural audio, synthesized audio, 2D graphics and 3D). From this context, MPEG-Pro, an MPEG-4 ...
