Abstract

Los métodos y aparatos codifican eficientemente datos multimedia, tales como flujos de videos en vivo. Una complejidad de codificacion de un intervalo de tiempo predeterminado, tal como 1 segundo, se estima antes de que la codificacion real sea utilizada. Esto permite que la codificacion real sea realizada con una estimacion a priori de la complejidad, permitiendo los bits asignados para el intervalo de tiempo predeterminado (velocidad de bit) que se asignará eficientemente dentro del intervalo de tiempo predeterminado. Además, la complejidad estimada se puede proporcionar a un dispositivo, tal como un multiplexor, que puede entonces asignar el ancho de banda disponible para una coleccion de canales de video multiplexados de acuerdo con la complejidad de codificacion anticipada para esos canales de video, que entonces permite que la calidad de un canal particular permanezca relativamente constante aun cuando el ancho de banda para la coleccion de canales de video multiplexados sean relativamente constante.
