Abstract

PARA LA INTRODUCCION COMPATIBLE DE UN FORMATO DE AMPLITUD DE IMAGEN 16 : 9 EN LOS MODELOS STANDARD DE TV EXISTENTES CON FORMATO 4 : 3 SE HA PREVISTO EL PROCESO LETTERBOX. EN ESTE PROCESO, LA INFORMACION DE IMAGEN 16 : 9 SE REPRESENTA SOBRE UN RECEPTOR 4 : 3 CON BANDAS NEGRAS EN LOS BORDES SUPERIOR E INFERIOR DE LA IMAGEN. PARA LA REPRESENTACION DE FORMATO COMPLETO CON RESOLUCION NO REDUCIDA SOBRE UN RECEPTOR 16 : 9, PUEDE SER TRANSMITIDA INFORMACION ADICIONAL EN LA FORMA DE MODULACION DE BANDA LATERAL EN UNA BANDA SUBPORTADORA DE CROMINANCIA DE LAS LINEAS DE LAS BANDAS NEGRAS. UN CIRCUITO DE FILTRO DE PEINE INTEGRADO PARA SEPARACION LUMINANCIA/CROMINANCIA SE DESCRIBE EN EL ARTICULO "ADACTIVE LUMINANZ-CHROMINANZ-TRENNUNG MIT UNTERSCHIEDLICH FARBTRAGERVERKOPPELTEN SAMPLING-THASES" (SEPARACION ADAPTADA LUMINANCIA-CROMINANCIA PARA UTILIZACION DE FASES DE MUESTREO CON DIFERENTES ACOPLAMIENTOS SUBPORTADORES-CROMINANCIA) POR R.SCHWEER Y M. PLANTHOLT, PUBLICADOS EN FERNSEHHNIK 12/1990. PUEDE SER UTILIZADO UN DECODIFICADOR DE FILTRO DE PEINE DIGITAL ADECUADAMENTE MODIFICADO CON ESTE CIRCUITO INTEGRADO A FIN DE OBTENER LA DEMODULACION DE INFORMACION ADICIONAL DE LAS SEÑALES DE COLOR COMPUESTAS EN EL PROCESO LETTERBOX COMO UNA ETAPA PREPARATORIA PARA LA GRABACION O REGISTRO DE TODOS LOS COMPONENTES DE TALES SEÑALES LETTERBOX UTILIZANDO UN GRABADOR DE VIDEO S-VHS O HI8.
