Abstract

Un metodo (200) o (300) y un sistema (100) para ejecutar un modo de truco en una senal de video. El metodo incluye los pasos de recibir (212) una instruccion de modo de truco, buscar (214) una imagen en la senal de video compatible con el modo de truco e iniciar (216) el modo de truco una vez que se localiza la imagen compatible. La imagen compatible puede ser una intra imagen o una imagen pronosticada. El modo de truco puede ser un modo de truco de congelacion, y el metodo tambien puede incluir el paso de repetir la imagen compatible por la duracion del modo de truco para formar la senal de modo de truco. El paso de repetir tambien puede incluir el paso de repetir tambien puede incluir el paso de repetir la imagen compatible por la duracion del modo de truco al insertar (218) dentro de la senal de video imagenes simuladas pronosticadas de la imagen compatible para formar la senal de video de modo de truco. Las imagenes simuladas pueden ser imagenes pronosticadas simuladas.
