The invention provides main data (MD) which includes embedded data (ED), the data being provided with a main data descriptor (MDD) for signaling a content included in the main data, wherein an embedded data descriptor (EDD) is formed for signaling content included in the embedded data and wherein the embedded data descriptor is provided outside the main data and the main data descriptor.

Embedded data signaling

Synthesizing an output audio signal is provided on the basis of an input audio signal, the input audio signal comprising a plurality of input sub-band signals, wherein at least one input sub-band signal is transformed (T) from the sub-band domain to the frequency domain to obtain at least one respective transformed signal, wherein the at least one input sub-band signal is delayed and transformed (D, T) to obtain at least one respective transformed delayed signal, wherein at least two processed signals are derived (P)from the at least one transformed signal and the at least one transformed delayed signal, wherein the processed signals are inverse transformed (T) from the frequency domain to the sub-band domain to obtain respective processed sub-band signals, and wherein the output audio signal is synthesized from the processed sub-band signals.

Converting decoded sub-band signal into a stereo signal

A frame structure is provided for streaming A/V data providing improved protecting and opportunities for concealing errors. The frame structure includes a header block and a plurality of sub-blocks. Each of the sub-blocks includes digitally encoded audio/video data corresponding to predetermined consecutive periods of the A/V signal. The sub-blocks are generally of variable length. For the header block and each of the sub-blocks a respective associated error protecting code is present in the frame for protecting the associated block during transmission. The header block also includes a location information field that provides information on the location of at least one of the sub-blocks in the frame.
