Abstract

Se proporciona un método para determinar ajustes de parámetros de memoria intermedia para una pluralidad de capas en un flujo de transporte. Cada capa incluye un ajuste de parámetro de memoria intermedia de flujo de transporte respectivo. Entonces, el método proporciona ajustes de parámetros de memoria intermedia de flujo de transporte respectivos a memorias intermedias de flujo de transporte individuales para capas respectivas en la pluralidad de capas. Entonces, el método almacena en memoria intermedia las capas respectivas en las memorias intermedias de flujo de transporte individuales de acuerdo con los ajustes de parámetros de memoria intermedia de flujo de transporte respectivos. Después del almacenamiento en memoria intermedia, el método combina las capas respectivas para formar un flujo de bits combinado.
