Claim 7:
8. A method for audio decoding, comprising:
reconstructing an audio signal, in units of audio frames of the audio signal, from a sequence of payload packets of an audio data stream, wherein each of the payload packets belongs to a respective one of a sequence of access units into which the audio data stream is partitioned, wherein each access unit is associated with a respective one of the audio frames; and
an audio truncator configured to be responsive to a truncation unit packet inserted into the audio data stream so as to truncate an audio frame associated with a predetermined access unit so as to discard, in playing out the audio signal, an end portion thereof indicated to be discarded in playout by the truncation unit packet,
wherein the truncation unit packet comprises
a truncation length element,
wherein the method comprises using the truncation length element as an indication of a length of the end portion of the audio frame,
wherein the method further comprises,
responding to a signaling in the predetermined access unit, switch between
decoding from the predetermined access unit the audio frame in a manner dependent on an access unit immediately preceding the predetermined access unit, in case of the signaling having a first state, or
decoding from the predetermined access unit the audio frame in a manner independent from an access unit immediately preceding the predetermined access unit, in case of the signaling having a second state.
