Abstract

Un sistema y un procedimiento para identificar cuando un proceso de transcodificación de medios indicado o predeterminado da como resultado un flujo de medios que cumpla con un punto de interoperabilidad indicado. Varias realizaciones permiten la codificación, el almacenamiento, la transcodificación y la transmisión de un flujo de medios, para el que el proceso de transcodificación esté identificado y el flujo de medios resultante del proceso de transcodificación está asociado con al menos una propiedad. La señalización de la propiedad o de las propiedades y la identificación del proceso de transcodificación en una modalidad, se pueden incluir en el flujo binario de medios, en un contenedor de formato de fichero que contenga el flujo binario de medios o en un protocolo de transmisión o control para la transmisión o el control del flujo binario de medios.
