Abstract

A method for transmitting encoded media data on the basis of a layer model includes dividing the media data onto a basic layer and at least one additional enhanced layer, transmitting the basic layer and the at least one enhanced layer via at least two network accesses, selecting a first network access to transmit the basic layer that has a network quality and/or stability that is sufficient for transmitting the basic layer; and selecting at least one second network access from among the network accesses depending upon the bandwidth of the first network access and the quality and stability of the network accesses for transmitting the at least one enhanced layer. An apparatus can be configured to execute the method. In some embodiments, the apparatus can include a communication system, a server computer device and/or a mobile terminal.
