Abstract

Se presenta un procedimiento para procesar vídeo codificado, por ejemplo insertando marcos generados, o ajustando los valores en los campos de temporización, o ajustando el tiempo en el que se le da salida, para ajustar la temporización de la salida del vídeo decodificado de un decodificador que recibe el vídeo codificado junto con su correspondiente aparato. El aparato de salida se puede incluir en un sistema de varias fuentes de vídeo, para permitir que se puedan sincronizar varias fuentes de vídeo. El vídeo de salida se puede sincronizar con un reloj de referencia de audio de estudio.
