Paper Abstract

H.264/MPEG-4 AVC is expected to cover wide range of applications not only for smaller images like CIF/QCIF but also for SDTV/HDTV. As encoding/decoding of larger images requires more number of macroblocks to be processed, any kind of technique for speeding up is indispensable for real-time applications. Pipeline processing is an effective tool for hardware implementation. However, when we apply it to intra prediction, additional constraint will be necessary, which causes a severe loss in coding efficiency. In this paper we propose modifications on intra prediction that enable us to apply pipeline processing with an ignorable level of loss in coding efficiency.
