| Abstract(in English) | An increasing number of audios and movies are recorded on digital for public as well as for professional applications in digital broadcasting systems like as DMB(Digital Multimedia Broadcasting), VOD(Vedio on Demand). In this paper, an algorithm for audio pre-coding analysis is recommended on filter design parameters, such as low frequency and high frequency, passband, stopband, ripple, and so on. These proposed power levels between successive frames of an audio pre-coded sequence make it to achieve coding efficiency for listening specific sounds of DMB. And this algorithm is considered as a three-dimensional signal with including three buffers for the audio pre-coding. Each buffer has three separated frequencies. As a result, faster searching time for DMB audio signals can be obtained from the analytic requirements of wireless LAN and digital broadcasting systems. |
