Abstract
SISTEMA DE SINCRONIZACION DE SEÑAL DE VIDEO PARA UN SISTEMA DE TRATAMIENTO DE SEÑAL DE TELEVISION DE PANTALLA ANCHA DE DEFINICION AMPLIADA, ENTRE SU GENERACION Y SU RECEPCION, INCLUYEN CIRCUITOS QUE GENERAN UNA SEÑAL DE ENTRENAMIENTO QUE INDICA LA POSICION DEL PRIMER ELEMENTO DE IMAGEN EN CADA INTERVALO DE LINEA HORIZONTAL DE LA SEÑAL DE VIDEO; ESTA SEÑAL DE ENTRENAMIENTO SE INSERTA EN UN INTERVALO DE LINEA HORIZONTAL DE LA SEÑAL DE VIDEO ACTIVA PARA TRANSMISION; UN RECEPTOR (1320) INCLUYE UN CIRCUITO (1325) QUE SEPARA LA SEÑAL DE ENTRENAMIENTO Y DEDUCE DE ELLA UNA SEÑAL DE TEMPORIZACION; LA SEÑAL DE TEMPORIZACION SE UTILIZA PARA DEFINIR LAS POSICIONES DE ELEMENTO DE IMAGEN DE DIVERSAS COMPONENTES DESCODIFICADAS DE LA SEÑAL DE VIDEO RECIBIDA PARA FACILITAR SU COMBINACION, SE UTILIZA TAMBIEN PARA ALINEAR LA SEÑAL SUBPORTADORA DE COLOR Y GENERAR OTRAS SEÑALES PORTADORA Y SUBPORTADORA UTILIZADAS EN EL PROCESO DE DESCODIFICACION.
