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. MPEG-21 is an open standards-based framework for multimedia delivery and(More)
The advanced video codec (AVC) standard, recently defined by a joint video team (JVT) of ITU-T and ISO/IEC, is introduced in this paper together with its performance and complexity co-evaluation. While the basic framework is similar to the motion-compensated hybrid scheme of previous video coding standards, additional tools improve the compression(More)
— Data transfers and storage are crucial cost factors in multi-media systems. Systematic methodologies are needed to obtain dramatic reductions in terms of power, area and cycle count. Upcoming multi-media processing applications will require high memory bandwidth. In this paper , we estimate that a software reference implementation of an MPEG-4 video(More)
Advanced multimedia systems intrinsically have a high memory cost, making the design of high performance, low power solutions a real challenge. Rather than spending most effort on implementation platform dependent optimization steps, we advocate a methodology and tool that involve C-level platform independent optimizations. This approach is applied to an(More)
