CODEC PLATFORM DEVICE CAPABLE OF INCREASING THE SATISFACTION OF A USER BY OMITTING A NEW CODE PLATFORM TRANSPLANTING OPERATION

摘要

PURPOSE: A codec platform device is provided to omit a new codec platform transplanting operation by performing the conversion of a digital signal sampled with a codec platform sampling frequency into a digital signal with a codec sampling frequency, and vice versa.;CONSTITUTION: An analog-digital converter(202) generates an analog input signal as a digital signal sampled with a codec platform sampling frequency. A sampling frequency converter(204) converts the digital signal sampled with a codec platform sampling frequency into a digital signal with a codec sampling frequency. An encoder(206) outputs a bit stream by compressing the digital signal with the codec sampling frequency. The sampling frequency converter comprises an up sampler, a low pass filter, and a download sampler.;COPYRIGHT KIPO 2010
