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 1):
An apparatus for generating a bit stream of encoded audio data representing a sequence of audio sample values of an audio signal, wherein the bit stream of encoded audio data comprise a plurality of frames, wherein each frame comprises associated encoded audio sample values, wherein the apparatus comprises:\n a special frame provider configured to provide at least one of the frames as a special frame, the special frame comprising encoded audio sample values associated with a current 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, and 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 current frame if the special frame is the first frame upon start-up of the decoder; and an output configured to output the bit stream of encoded audio data, wherein the bit stream of encoded audio data comprises a plurality of segments, wherein each segment is associated with one of a plurality of portions of the sequence of audio sample values and comprises a plurality of frames, wherein the special frame provider is configured to add a special frame at the beginning of each segment irrespective of whether the codec configuration changes or not, and wherein the special frame within the generated bitstream of encoded audio data permits switching between different codec configurations at the decoder.
