10. MPEG-21: goals and achievements

Author

Burnett, I., Van de Walle, R., Hill, K., Bormans, J., Pereira, F., Burnett, I., Van de Walle, R., Hill, K., Bormans, J., and Pereira, F.

Abstract

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.

Abstract

Due to the large amount of data transfers it involves, the motion estimation (ME) engine is one of the most power-consuming components of any predictive video codec. As a consequence, power-optimized video coding primarily relies on a carefully designed motion estimator. This paper first presents a block ME algorithm that meets high-quality inter-frame prediction and low computational complexity requirements. It relies on a set of rules common to all recent fast and adaptive ME algorithms, but is designed in order to allow for easy and prolific data reuse. The adjacent order of the candidate positions during the search increases the locality and maintains a near-regular data flow, which results in a decrease of the data transfers and a low control complexity. Together with, the computational complexity reduction, it enables cost-efficient very large scale integration realizations. A pipelined parallel architecture is then proposed and discussed. It is generic in the sense that it is suited both to the full-pel and half-pel ME. I It is efficient, because it allows for close to 100% hardware utilization and a sharp decrease of the peak memory bandwidth. It is suited to low-power implementation, as it enables larger data reuse factors for the most probable stages of the adaptive algorithm, which reduces the average memory bandwidth and power consumption.
