Abstract

Métodos y aparatos para codificar datos multimedia haciendo posible, entre otros, por ejemplo, la mejora de la calidad de video decodificado, la mejora de las capacidades de recuperacion de error mejorado y/o la mejora de eficiencia de decodificacion. Un método de acuerdo con la aplicacion incluye uno o más de lo siguiente: inicializar un contador de referencia de nivel de pixel para un cuadro vigente, llevar a cabo una prediccion de un proximo cuadro al que hace referencia el cuadro vigente, incrementar el contador de referencia de nivel de pixel para cada pixel del cuadro vigente al que se hace referencia durante la prediccion del proximo cuadro, reajustar un mapa de ancho de banda de macro bloque del cuadro vigente, repetir los pasos de inicializacion, llevar a cabo y reajustar para cada proximo cuadro en una pluralidad de proximos cuadros que se refieren al cuadro vigente, y codificar el cuadro vigente sobre la base, por lo menos en parte, en el mapa de ancho de banda del macro bloque reajustado del cuadro vigente.
