Abstract
Un sistema de procesamiento de señal de video que se puede configurar de manera dinámica, procesa datos en la forma de capas jerárquicas. EL sistema divide los datos entre capas jerárquicas, y permite variacion en el numero de capas empleadas. Los datos se dividen automáticamente entre una o más capas jerárquicas como una funcion de uno o más parámetros seleccionados a partir de una amplitud de banda del sistema disponible, velocidad de los datos de entrada, y calidad de señal de salida. En adicion, la resolucion de imagen y el numero correspondiente de píxeles por imagen de los datos puede variar como una funcion de parámetros del sistema. Se describen los sistemas tanto codificador (100) como descodificador (105; 107; 109).
