Abstract

Al seleccionar un usuario un modo de truco particular, el numero de imagenes que se despliegan se puede ajustar de acuerdo con ello para que correspondan a la velocidad de modo de truco seleccionada, basandose en un tiempo de despliegue determinado. Subsecuentemente, se puede determinar el uso de ancho de banda para asegurar que la capacidad del canal entre un aparato de reproduccion y un decodificador remoto no haya sido excedida. Para modos de truco de avance, en un caso en donde el ancho de banda entre el aparato reproductor y el decodificador remoto serian excedidos, las imagenes B se puede eliminar uniformemente a lo largo del segmento reproducido. Cuando habia presentes imagenes B y estas fueron eliminadas, se pueden reemplazar por imagenes B simuladas. Una vez mas, si el ancho de banda disponible todavia es insuficiente entre el aparato reproductor y el decodificador remoto, entonces se puede eliminar imagenes P del segmento reproducido y se pueden reemplazar uniformemente por imagenes P simuladas.
