Abstract
An audio system has an attacher station for attaching to and decoding an audio representation channel, which also has a first auxiliary information sub-channel. A user station is fed by the attacher station through a unidirectional interface and receives the auxiliary information in an application context under control of a user interface for selective displaying. The attacher station extracts the auxiliary information from the channel. The system also has a framework data generator that is instantiatable by information from the information sub-channel, and a framework packetizer fed by the generator for supplementing the audio representation channel on said unidirectional interface in a second auxiliary information sub-channel by packetized and instantiated application information for the user station.
