Abstract

Un metodo (200) y un sistema (100) para ejecutar un modo de truco en una senal de video. El metodo incluye los pasos de recibir (210) una instruccion de modo de truco, en repuesta a la instruccion de modo de truco, repetir (212) una imagen de senal de video para formar una senal de video de modo de truco en donde la imagen contiene un indicador de despliegue; ajustar (214) el indicador de despliegue de la imagen a ser repetida a un valor predeterminado; y ajustar (216) los indicadores de despliegue de las imagenes repetidas posteriores de la imagen a ser repetida a un valor predeterminado. En un arreglo, el modo de truco puede ser un modo de truco de congelacion y la imagen a ser repetida puede ser una imagen pronostica bidireccional. Ademas, el indicador de despliegue puede ser un campo de referencia temporal que tiene un valor entero.
