Abstract

ESTE INVENTO PERMITE QUE UNA SEÑAL DE TELEVISION EN COLOR SEA CODIFICADA EFICIENTEMENTE POR UN TRANSFORMADOR UNIDIMENSIONAL O BIDIMENSIONAL, ADOPTANDO DE ESTA FORMA UN PULSO DE MUESTREO DE FRECUENCIA VARIABLE Y UN PROCESAMIENTO DIGITAL DE LA SEÑAL MUESTREADA. DE ESTA FORMA, UNA SEÑAL ANALOGICA SIMPLE PUEDE TRANSFORMARSE EN TRES SEÑALES QUE TIENEN CARACTERISTICAS ESTADISTICAS SIMILARES A LAS SEÑALES COMPUESTAS (Y, U, V EN EL CASO DEL SISTEMA PAL). LA CODIFICACION A TRAVES DE LA TRANSFORMACION DE LAS SEÑALES OBTENIDAS CON EL SISTEMA DE ESTE INVENTO PERMITE ALCANZAR UNA ALTA COMPRESION DE LA INFORMACION A TRANSMITIR. ADEMAS ES POSIBLE TRATAR UNIFORMEMENTE DICHAS SEÑALES COMPUESTAS Y DICHAS SEÑALES DE COMPONENTES POR MEDIO DE UN SISTEMA FISICO PRACTICAMENTE IDENTICO.
