Abstract

Se proporciona un sistema para transmitir datos (vease la Figura 2). El sistema consiste en un sistema de analisis de tramas (vease la pagina 2, elemento 106) que recibe los datos en tramas, como puede ser una trama de datos de video, y genera datos de region (vease la Figura 2, elemento 113), como puede ser un tamano de matriz uniforme (Figura 2, elemento 304) que es necesaria para dividir la trama en una serie de matrices predeterminada. Un sistema de seleccion de pixeles (Figura 2, elemento 108) recibe los datos de la region y genera una serie de datos de pixeles para cada region, como puede ser al seleccionar uno de los pixeles contenido dentro de cada una de las matrices originales que comprenden la trama (Figura 2, elemento 104).
