Abstract
UNA TAL SEÑAL SE DIVIDE EN DOS COMPONENTES DE SEÑAL RESPECTO A CANALES DE TRANSMISION LIMITADAS EN CUANTO AL ANCHO DE BANDA, QUE SE TRANSMITEN MEDIANTE DOS CANALES SEPARADOS. LA PRIMERA COMPONENTE DE SEÑAL REPRESENTA UNA SEÑAL TV ESTANDARD Y LA SEGUNDA COMPONENTE UNA SEÑAL DE IMAGEN DE ALTA RESOLUCION LOCAL. COMO SEGUNDA COMPONENTE DE SEÑAL SE TRANSMITE UNA SEÑAL CON LA MISMA ALTA DEFINICION LOCAL COMO LA SEÑAL DE ENTRADA. LA RESOLUCION TEMPORAL SE DISMINUYE. SISTEMA DE TRANSMISION COMPATIBLE DE TELEVISION PARA LA SEÑAL HDTV
