Abstract:
1. An apparatus for time scaling a signal comprising: means for receiving an input signal comprising a first signal and extension data associated with the first signal; means for generating a time scaled signal of the first signal; means for generating a plurality of frequency sample blocks for the time scaled signal, each frequency sample block corresponding to a fixed time interval of the time scaled signal, the fixed time interval being independent of a time scaling factor; means for determining a first time-association between a first parameter value of the extension data and a first frequency sample block having an associated first time interval of the time scaled signal; means for determining a second parameter value associated with a second frequency sample block in response to the first time-association and the first parameter value; means for modifying data of the second frequency sample block in response to the second parameter value; and means for generating time domain output sample blocks from the frequency sample blocks.
