Abstract
Procedimiento de codificación en línea de imágenes de vídeo con cuantificación de datos, que comprende una etapa de cálculo de un paso de cuantificación (6, 11) relativo a una imagen actual en función de un caudal deseado y de una información de calidad subjetiva (5, 9), caracterizado porque la imagen actual es tratada para obtener una imagen degradada correspondiente, cuya comparación con la imagen actual permite calcular la información de calidad subjetiva y porque la imagen actual es retardada (8) igualmente durante este tratamiento para efectuar su codificación en función de esta información de calidad subjetiva.
