Description: The MPEG-1 Layer III (MP3) algorithm is one of the most successful audio The MPEG-1 Layer
III (MP3) algorithm is one of the most successful audio formats for consumer audio storage and for
transfer and playback of music on digital audio players. The MP3 compression standard along with
the AAC (Advanced Audio Coding) algorithm are associated with the most successfulmusic players
of the last decade. This book describes the fundamentals and theMATLAB implementation details
of the MP3 algorithm. Several of the tedious processes in MP3 are supported by demonstrations
using MATLAB® software. The book presents the theoretical concepts and algorithms used in
the MP3 standard. The implementation details and simulations with MATLAB® complement the
theoretical principles. The extensive list of references enables the reader to perform a more detailed
study on specific aspects of the algorithm and gain exposure to advancements in perceptual coding.-The MPEG-1 Layer III (MP3) algorithm is one of the most successful audio The MPEG-1 Layer

Description: Context-adaptive binary arithmetic coding (CABAC) is a form of entropy encoding used in the H.264/MPEG-4 AVC and High Efficiency Video Coding (HEVC) standards. It is a lossless compression technique, although the video coding standards in which it is used are typically for lossy compression applications. CABAC is notable for providing much better compression than most other entropy encoding algorithms used in video encoding, and it is one of the key elements that provides the H.264/AVC encoding scheme with better compression capability than its predecessors.

Description: Intra-frame coding is used in video coding (compression). It is part of an intra-frame codec like ProRes: a group of pictures codec without inter frames.
Intra-frame prediction exploits spatial redundancy, i.e. correlation among pixels within one frame, by calculating prediction values through extrapolation from already coded pixels for effective delta coding. It is one of the two classes of predictive coding methods in video coding. Its counterpart is inter-frame prediction which exploits temporal redundancy. Temporally independently coded so-called intra frames use only intra coding. The temporally coded predicted frames (e.g. MPEG's P- and B-frames) may use intra- as well as inter-frame prediction.
