Title (EN) MPEG ENCODING METHOD FOR LOGO INSERTION
(FR) PROCEDE DE CODAGE MPEG PERMETTANT L'INTRODUCTION DE LOGOS
Abstract: front page image
(EN)When MPEG encoding a video signal, a set of macroblocks is defined to form the site for downstream insertion of a logo. The encoder forces the coding of the set of macroblocks into an intra-coding mode. It also inhibits the use, in coding of any other macroblock, of a motion vector directed to any of the set of macroblocks. The aggregate bit rate over the set of macroblocks is controlled so as to simplify logo insertion or to maintain picture quality in the logo region.
(FR)Lorsque MPEG code un signal vidéo, un ensemble de macroblocs est défini pour former le site permettant l'introduction en aval d'un logo. Le codeur force le codage de l'ensemble de macroblocs dans un mode de codage interne. Le codeur empêche également l'utilisation, lors du codage d'autre macroblocs, d'un vecteur de mouvement dirigé à un macrobloc de l'ensemble. Le débit global sur l'ensemble de macroblocs est régulé de façon à simplifier l'introduction de logo ou à maintenir une qualité d'image dans la zone du logo.
