| Popis: | 87 As the coming of multimedia age, the way of information representation, like video, audio, image, animation, is more attractive to us. With it, the most important issue is how to deal with large amount of data. The first aid is how to efficiently represent the informative data, with limited to the bandwidth of digital storage and network. Nowadays, perceptual audio coding is the mainstream in the field of audio coding, and the standardization activities are kept going. It uses perceptual model to reduce the redundancy that would not be heard. The most well known standard at all is ISO/IEC 11172-3, known as MPEG1/Audio, and ISO/IEC 13813-3, known as MPEG2/Audio. In this thesis, the framework of MPEG1/Audio codec would be firstly presented. The main concept of perceptual audio coding, psycho-acoustic theory and dynamic bit allocation is followed. In the following chapters, the main body of this thesis would be carried out, that is MPEG2/Audio. We would get familiar with it through the implementation. |
