With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.

MTOOLS version 2.0 Mtools is a public domain collection of programs to allow Unix systems to read, write, and manipulate files on an MSDOS filesystem (typically a diskette). The following MSDOS commands are emulated: Mtool MSDOS name equivalent Description ----- ---- ----------- mattrib ATTRIB change MSDOS file attribute flags mcd CD change MSDOS directory mcopy COPY copy MSDOS files to/from Unix mdel DEL/ERASE delete an MSDOS file mdir DIR display an MSDOS directory mformat FORMAT add MSDOS filesystem to a low-level format mlabel LABEL make an MSDOS volume label. mmd MD/MKDIR make an MSDOS subdirectory mrd RD/RMDIR remove an MSDOS subdirectory mread COPY low level read (copy) an MSDOS file to Unix mren REN/RENAME rename an existing MSDOS file mtype TYPE display contents of an MSDOS file mwrite COPY low level write (copy) a Unix file to MSDOS

MPEG-2 has 7 distinct parts as well. The first part is the Systems section which defines the container format and the Transport Streams that are designed to carry the digital video and audio over ATSC and DVB. The Program Stream defines the container format for lossy compression on optical disks, DVDs and SVCDs.

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns. This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.

Please read this document before attempting to compile and run the libraries and applications! The projects must be compiled in a particular order. Standard support questions are about compiler and/or linker errors that are generated when users try to compile the projects in the wrong order. Other information of interest is available here, so read the entire document fi rst. Wild Magic Version 2.1 is what ships with the fi rst printing of the Game Physics book. Some of the applications that are referenced in the book did not make it onto the CD–ROM for the book. Version 2.2 contains those applications, plus more
