Each MPEG audio frame contains either 384 (Layer 1) or 1152 (Layer 2) audio samples per channel. However, each input buffer to the encoder may contain any number of PCM samples. The size of each input buffer must be a multiple of the block alignment.

MPEG DECODER Figure 3.2: MPEG DECODER block diagram The MPEG audio standard has three distinct layers for compression. Layer I is the basic algorithm Layers II and III are enhancements of Layer I. Each successive layer improves the compression performance at the increasing cost of encoder and decoder complexity. a) Layer 1. ]

Figure 1 shows block diagrams of the MPEG/audio encoder and decoder. The input audio stream passes through a filter bank that divides the input into multiple subbands of frequency. The input audio stream simultaneously passes through a psychoacoustic model that determines the ratio of the signal energy to the masking threshold for each subband.

MPEG Advanced Audio Coding MPEG doc#: N7704 Date: October 2005 Author: S. Quackenbush What it does: Advanced Audio Coding (AAC) is a multi-channel perceptual audio coder that provides excellent compression of music signals while achieving transparent quality relative to a stereo Compact Disc original for audio material when coded at 128 kb/s.

Block diagram of MPEG/ITU-T video encoder/decoder. On the decoder side, all the necessary information for picture reconstruction, including motion vectors and transform coefficients, are retrieved from encoded video bitstream by using an entropy-decoding technique such as variable-length decoding (VLD).

A simplified MPEG-2 encoder and decoder are shown in the MPEG Coder/Decoder Diagram. Encoding: The encoding process for P and B pictures is explained as follows. Data representing macroblocks of pixel values for a picture to be encoded are fed to both the subtractor and the motion estimator. The motion estimator compares each of these new ...
