Abstract

UN SISTEMA DE COMPRESION/DESCOMPRESION COMPRENDE UNA FUENTE (10) DE SEÑAL DE VIDEO EXPLORADA NO ENTRELAZADA (1:1 60HZ). UN PREPROCESADOR (12) CONSTRUYE UNA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA A PARTIR DE LA SEÑAL DE VIDEO EXPLORADA NO ENTRELAZADA (2:1 60HZ) POR SELECCION DE LINEAS ALTERNAS DE SEÑALES DE IMAGEN NO ENTRELAZADAS SUCESIVAS. LA SEÑAL DE VIDEO EXPLORADA ENTRELAZADA SE COMPRIME (14) DE ACUERDO CON U PROTOCOLO MPEG DE ALGORITMOS DE COMPRENSION DE MARCO I, P Y B. LA COMPRESION DE LOS MARCOS I, P Y B SE REALIZA DE MANERA QUE HAY UN NUMERO IMPAR, MAYOR QUE UNO, MARCO B ENTRE SUCESIVOS MARCOS I/P (POR EJEMPLO LA SECUENCIA DE MARCOS COMPRIMIDOS PUEDE CONFORMAR EN (I, B1, B2, B3, P, B1, B2, B3, P, B1, B2, B3, I, B1, ,) EL MARCO COMPRIMIDO I , LOS MARCOS COMPRIMIDOS P Y LOS MARCOS COMPRIMIDOS B ALTERNOS ( LOS MARCOS B2 EN LA SECUENCIA DE EJEMPLO) FORMAN SELECTIVAMENTE (5, 16) UNA SEÑAL DE VIDEO ENTRELAZADA (2:1 30HZ) COMPRIMIDA PARA LA REPRODUCCION POR RECEPTORES EXPLORADOS ENTRELAZADOS.LOS MARCOS B INTERVINIENTES FORMAN SELECTIVAMENTE UNA SEÑAL DE VIDEO SECUNDARIA COMPRIMIDA. LAS SEÑALES DE VIDEO COMPRIMIDA PRIMARIA Y SECUNDARIA SON RECIBIDAS POR RECEPTORES EXPLORADOS NO ENTRELAZADOS PARA REPRODUCIR IMAGENES EXPLORADAS NO ENTRELAZADAS, MIENTRAS LA SEÑAL PRIMARIA PUEDE SER REPRODUCIDA POR RECEPTORES EXPLORADOS ENTRELAZADOS.
