Abstract

SEÑAL PARA SISTEMA DE TRANSMISION DE TELEVISION QUE TRANSPORTA UNA SEÑAL DE INFORMACION DE MOVIMIENTO ADEMAS DE LA SEÑAL VISUAL. EN EL EXTREMO DE TRANSMISION, CADA CAMPO DE UNA IMAGEN SE SUBDIVIDE EN VARIAS REGIONES, GENERANDOSE UN DETERMINADO NUMERO DE LOS VECTORES DE MOVIMIENTO DOMINANTES ADECUADO A UNA REGION. ESTOS VECTORES DE MOVIMIENTO SE TRANSMITEN COMO SEÑAL DE INFORMACION DE MOVIMIENTO, SEPARANDOSE EN UN RECEPTOR DE LA SEÑAL DE TELEVISION EN UN DECODIFICADOR (12). LOS PUNTOS DE IMAGEN DESCENTRADOS ESPACIALMENTE SE IDENTIFICAN EN UN PRIMER CIRCUITO ESPACIAL DE DESVIACION (14) EN UNA SEÑAL VISUAL RETARDADA POR UNA MEMORIA DE IMAGEN (16) Y SE COMPARAN EN UN CIRCUITO DE COMPARACION DE INFORMACION DE IMAGEN (17) CON PUNTOS DE IMAGEN EN EL CAMPO CORRESPONDIENTE DE LA IMAGEN PARA IDENTIFICAR EL VECTOR DE MOVIMIENTO QUE INDICA EL PUNTO DE IMAGEN DE MAGNITUD CORRESPONDIENTE. ESTO SE APLICA A LA ENTRADA DE UN SEGUNDO CIRCUITO ESPACIAL DE DESVIACION (19), UNA SEGUNDA ENTRADA DEL CUAL RECIBE LA SEÑAL VISUAL RETARDADA PARA PRODUCIR PUNTOS DE IMAGEN DE MOVIMIENTO COMPENSADO QUE, JUNTO CON LOS PUNTOS DE IMAGEN DE LA SEÑAL ACTUAL VISUAL, SUFREN UNA ELEVACION DE FRECUENCIA Y SE INTERPOLAN EN UNA UNIDAD (18) PARA GENERAR UNA SEÑAL VISUAL DE MAYOR FRECUENCIA.
