Abstract

Un aparato de transmision de datos para realizar la transmision de un conjunto de datos original que tiene un convertidor que ejecuta la conversion del conjunto de datos original en codigos de datos secuenciales. El codigo de datos está formado por la combinacion de codigos binarios de ALTO nivel, y conjuntos binarios de BAJO nivel. La longitud máxima de los codigos binarios continuos de un nivel, en los que dicho nivel ALTO, dentro de los codigos de datos está limitado a un valor Tmax, por ejemplo, de hasta 14T, en donde T es una unidad de longitud que representa un codigo binario y la longitud mínima de codigos binarios continuos de un nivel, en los que el nivel ALTO, se encuentra en los codigos de datos y está limitado a un valor Tmin, que por ejemplo, es de 3T. Un elemento generador que genera un codigo de sincronizacion. Dicho codigo de sincronizacion está formado por la combinacion de codigos binarios de nivel ALTO y BAJO. El codigo de sincronizacion antes mencionado comprende un elemento identificador que tiene codigos binarios continuos de un nivel, y dicho nivel es ALTO, con una longitud predeterminada de 16T, la cual es 2T mayor que un valor Tmax. Y un elemento insertador, que inserta el codigo de sincronizacion de una manera intermitente dentro de los codigos de datos secuenciales.
