Abstract
UN SISTEMA DE COMPRESION/DESCOMPRESION COMPRENDE UNA FUENTE (10) DE SEÑAL DE VIDEO EXPLORADA NO ENTRELAZADA. UN PROCESADOR (12) CONSTRUYE UNA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA A PARTIR DE LA SEÑAL DE VIDEO EXPLORADA NO ENTRELAZADA POR SELECCION DE LINEAS ALTERNAS DE SEÑALES DE IMAGEN NO ENTRELAZADAS SUCESIVAS.LA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA SE COMPRIME (14) DE ACUERDO CON METODOS CONOCIDOS PARA GENERAR DATOS DE VIDEO COMPRIMIDOS PRIMARIOS.EL DATO PRIMARIO SE DESCOMPRIME (22) POR PROCESOS CONOCIDOS INVERSOS A LOS PROCESOS DE CONVERSION, PARA GENERAR LOS MARCOS EXPLORADOS ENTRELAZADOS, SEÑAL DE VIDEO EXPLORADA ENTRELAZADA, QUE CORRESPONDE A LAS LINEAS NO ENTRELAZADAS QUE NO ESTABAN INCLUIDAS EN LA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA, SE PREDICE (24) DE LOS MARCOS DESCOMPRIMIDOS DE SEÑAL DE VIDEO. ADEMAS LAS LINEAS DE INTERVENCION DE LA SEÑAL DE VIDEO EXPLORADA NO ENTRELAZADA ORIGINAL, QUE NO ESTABAN INCLUIDAS EN LA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA PRIMARIA, ESTAN FORMADAS (20)DENTRO DE LA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA SECUNDARIA.LA SEÑAL DE VIDEO SECUNDARIA (26) SE SUSTRAE DE LA SEÑAL DE VIDEO PREDICHA PARA GENERAR RESIDUOS DE CAMPO SECUNDARIO.ESTOS RESIDUOS ESTAN COMPRIMIDOS (30) POR METODOS CONOCIDOS PARA FORMAR DATOS DE VIDEO SECUNDARIOS COMPRIMIDOS.LOS DATOS COMPRIMIDOS PRIMARIO Y SECUNDARIO SE TRANSMITEN DESPUES (18,34,40,42) PARA SU RECEPCION BIEN POR RECEPTORES EXPLORADOS O RECEPTORES EXPLORADOS NO ENTRELAZADOS.
