Abstract
EN UN SISTEMA DE PROCESAMIENTO DE SEÑALES DIGITALES DE TELEVISION (10, 12 Y 14-18), UNA PALABRA CLAVE ESPECIAL, UN SEÑALADOR DE ALINEACION DE PAQUETES (PAF), SE INTRODUCE EN UN FLUJO DE BITS DE PALABRAS CLAVE DE MPEG PARA SIGNIFICAR LA PRESENCIA DE UN GRUPO DE IMAGENES (GOP). EL PAF PRECEDE INMEDIATAMENTE A UNA PALABRA CLAVE DE COMIENZO DE IMAGEN PARA UN CUADRO "I", QUE INICIA UN GOP. UN PAQUETE DE DATOS EN CONSTRUCCION SE FINALIZA CUANDO APARECE UN PAF, YA QUE ESTA PREVISTO QUE UN GOP COMIENCE EN EL LIMITE DE UN PAQUETE. TAL FINALIZACION PUEDE RESULTAR EN UN PAQUETE ABREVIADO DE MENOS DEL NUMERO PRESCRITO DE PALABRAS CLAVE NECESARIO PARA COMPLETAR UN PAQUETE DE DATOS. LA ULTIMA PALABRA DE CADA PAQUETE SE DESIGNA DE ESTA MANERA PARA FACILITAR LA POSTERIOR COMBINACION DE LOS PAQUETES DE DATOS CON SUS RESPECTIVAS CABECERAS. UN PAQUETE DE DATOS INCOMPLETO SE RELLENA CON PALABRAS NULAS (BITS A CERO) PARA LOGRAR UN PAQUETE DE DATOS COMPLETO CON UN NUMERO O PALABRA PRESCRITOS.
