Abstract
Described herein is an audio decoder for decoding a bitstream of encoded audio data, wherein the bitstream of encoded audio data represents a sequence of audio sample values and comprises a plurality of frames, wherein each frame comprises associated encoded audio sample values, the audio decoder comprising: a determiner configured to determine whether a frame of the bitstream of encoded audio data is an immediate playout frame comprising encoded audio sample values associated with a current frame and additional information; and an initializer configured to initialize the decoder if the determiner determines that the frame is an immediate playout frame, wherein initializing the decoder comprises decoding the encoded audio sample values comprised by the additional information before decoding the encoded audio sample values associated with the current frame. Described are further a method for decoding said bitstream of encoded audio data as well as an audio encoder, a system of audio encoders and a method for generating said bitstream of encoded audio data with immediate playout frames. Described are moreover also an apparatus for generating immediate playout frames in a bitstream of…
