Title: Bit allotting method in ac-3 decoder

Filed: 1998-12-30
Abstract: PURPOSE: A bit allotting method in an AC-3 decoder is provided to be capable of replacing an iteration calculation owing to a simple loop with a look-up table so as to mitigate a load of a processor by simplifying the procedure of a bit allotment to discretely calculated audio data of a channel in an audio signal. CONSTITUTION: In a bit allotting method in an AC-3 decoder, 253 audio data on a frequency axis is extracted by performing a discrete time transformation at a channel of the most front part of an audio block(302). A look-up table is searched in order to allot a bit to the extracted audio data in a corresponding order by loading the look-up table from a low frequency(304). Whether some discrete calculation values correspond to a power spectrum density is judged with reference to the look-up table(306). 1, 3, 6, 12 or 24 discrete calculation values are calculated into a corresponding power spectrum density value according to the result(308). Whether the number of the calculated power spectrum density is 50 is judged with reference to data stored in the look-up table(310). If all of 50 power spectrum densities are calculated, there is performed a calculation of allotting discrete calculated values of a next channel(312). If at least one of the 50 power spectrum densities is not calculated, the procedure goes to the step(306).
