Abstract:
An audio decoder decodes a bit stream of encoded audio data, which bit stream represents a sequence of audio sample values and includes a plurality of frames, wherein each frame includes associated encoded audio sample values. The audio decoder includes a determiner configured to determine whether a frame of the encoded audio data is a special frame including encoded audio sample values associated with the special frame and additional information, wherein the additional information include encoded audio sample values of a number of frames preceding the special frame, wherein the encoded audio sample values of the preceding frames are encoded using the same codec configuration as the special frame, wherein the number of preceding frames is sufficient to initialize the decoder to be in a position to decode the audio sample values associated with the special frame if the special frame is the first frame upon start-up of the decoder.

Claim (Index 15):
A method for decoding a bit stream of encoded audio data, wherein the bit stream 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, comprising:\n determining whether a frame of the encoded audio data is a special frame comprising encoded audio sample values associated with the special frame and additional information, wherein the additional information comprise encoded audio sample values of a number of frames preceding the special frame, wherein the encoded audio sample values of the preceding frames are encoded using the same codec configuration as the special frame, wherein the number of preceding frames, corresponding to pre-roll frames, corresponds to the number of frames needed by a decoder to build up the full signal during start-up of the decoder so as to be in a position to decode the audio sample values associated with the special frame if the special frame is the first frame upon start-up of the decoder; initializing the decoder if it is determined that the frame is a special frame, wherein the initializing comprises decoding the encoded audio sample values comprised by the additional information before decoding the encoded audio sample values associated with the special frame; switching the audio decoder from a current codec configuration to a different codec configuration if it is determined that the frame is a special frame and if the audio sample values of the special frame have been encoded using the different codec configuration; and decoding the special frame using the current codec configuration and discarding the additional information if it is determined that the frame is a special frame and if the audio sample values of the special frame have been encoded using the current codec configuration.
