1 EE412/CS455: Principles of Digital Audio and Video Spring Course Catalog Description The course provides the student with necessary concepts and techniques regarding digital audio and video. Topics include: Introduction to multimedia systems its components and applications, digital signal processing of audio, images, and video data in multimedia systems and their formats. Introduction is also given regarding compression and communication of audio and video media. Students will also be oriented regarding the appropriate hardware platform for applications related to digital audio and video. This course is a must for Electronics Engineers as a number of electronics devices are meant for digital audio or video. Designing of such systems require knowledge of processing requirement that these media imposes on the hardware. It is also a very important applied course for CS students who want to work in industry or do research involving audio and video data. It explains how the digital audio and video signals are produced and processed based on the digital signal processing concepts, compressed and uncompressed formats in which these signals exist, how electronic devices reproduce the real life experience, design principle and high level architecture of such devices etc. Assignments and home works will be geared towards this goal. Course website will provide for assignment handouts, additional reading material, web links and other information related to the course. This course is intended to be a foundation course for the multimedia/vision/image processing concentration area both for under-graduate and graduate students of Electrical Engineering and Computer Science. Course credit can be claimed towards both programs in EE and CS as per policy. Some assignments and project for graduate students will be more advanced than for undergraduate students. COURSE OBJECTIVES The goal of this course is to arouse interest in students and to prepare necessary background to pursue further research and advanced course work in vision/ video processing and speech signal processing problems and their implementation. The goal of this course is also to facilitate students to produce better quality EE (and CS) senior projects by providing them necessary insight and experience related to techniques involving digital audio and video which is frequently used in such projects. Course Details Credit Hours 3 Core Elective Elective course for EE/CS undergraduate and graduate students Open for Student Category EE/CS Senior and Junior students; EE/CS Graduate students; Closed for Student Category Freshman, Sophomore Course Prerequisite(s)/Co-Requisite(s) Pre-requisites: EE or CS standing at following levels: Junior, Senior, Graduate; Some programming knowledge/experience in Matlab, C, C++ (like CS100 and CS200) is required which could be completed in any course.
