Abstract

La codificacion sin perdida predictiva proporciona una compresion de imagen sin perdida efectiva del contenido fotografico y grafico en un medio de imagen y video. La codificacion sin perdida predictiva puede operar en una base de macrobloque para la compatibilidad con los codecs existentes de imagen y video. La codificacion sin perdida predictiva selecciona y aplica uno de multiples modos de modulacion de codigo por impulso diferencial (DPCM) disponibles, en macrobloques individuales para producir los residuos DPCM que tiene una distribucion mas cercana a la optima para la codificacion por entropia Golomb-Rice RLGR de longitud de ejecucion. Esto permite la codificacion de entropia sin perdida efectiva a pesar de las diferentes caracteristicas del contenido de imagen fotografico y de graficos.
