Nowadays several electronics devices support digital videos. Some examples of these devices are cellphones, digital cameras, video cameras and digital televisions. However, raw videos present a huge amount of data, millions of bits, for their representation as the way they were captured. To store them in its primary form it would be necessary a huge amount of disk space and a huge bandwidth to allow the transmission of these data. The video compression becomes essential to make possible information storage and transmission. Motion Estimation is a technique used in the video coder that explores the temporal redundancy present in video sequences to reduce the amount of data necessary to represent the information. This work presents a hardware architecture of a motion estimation module for high resolution videos according to H.264/AVC standard. The H.264/AVC is the most advanced video coder standard, with several new features which allow it to achieve high compression rates. The architecture presented in this work was developed to provide a high data reuse. The data reuse schema adopted reduces the bandwidth required to execute motion estimation. The motion estimation is the task responsible for the largest share of the gains obtained with the H.264/AVC standard so this module is essential for final video coder performance. This work is included in Rede H.264 project which aims to develop Brazilian technology for Brazilian System of Digital Television

This paper considers Judith Kestenberg's approach to the psychic contextualization of human body movements, presenting: 1) the main movement categories identified by Kestenberg and their meanings; 2) the relations (affinities and shocks) within these movement patterns; 3) the relations between the initial preferences of a child for certain rhythms of movements and his/her movement patterns in adult life. The aim of this research was to present Kestenberg's studies, which offer a necessary knowledge to those willing to comprehend human body movement in a therapeutic context.
