1 EE 412/CS455 Principles of Digital Audio and Video Instructor s Name: Nadeem A. Khan Year: Office No. & Room 426, nkhan@lums.edu.pk Category: Senior, Junior and Graduates (Elective) Course Code (Units) Course Description EE 412/CS455 Principles of Digital Audio and Video (3 Units) This course provides the student with basic concepts and techniques regarding digital audio and video in multimedia systems. 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. Assignments and home works will be geared towards this goal. This course is intended to be a foundation course for the multimedia/vision/image processing concentration area. It is designed for undergraduate-level students majoring in Electrical Engineering and Computer Science. However most of the graduate students will find it equally useful.

2 Core/Elective Pre-requisites Goals This course is an elective for undergraduate and graduate Computer Science and Electrical Engineering students. Only for EE and CS and students at one of the following levels: Junior, Senior, Graduate; Some programming knowledge/experience in Matlab, C, C++ (like CS100 and CS200) is required (Recommended: Signal and Systems, Computer Organization and Assembly, Digital Logic Design ). Students with no background in Signal and Systems will have to attend a few mandatory tutorials. To build the necessary background for advanced courses in the Multimedia/Vision and Image Processing related streams

Theory sessions will be of 75 minutes each and Practical sessions will be of 2 hrs and 20 mins. Assignment 2 which is based on reviewing basic Signal and systems concepts will be differently structured and graded for students with no signal and systems background. One or two initial tutorials will also be

4 compulsory to attend for background makeup. Class attendance is strongly advised. However, students missing lectures will find it very difficult to make up for the content covered. Grading Assignments/Labs: 16% Project: 10% Quizzes: 19% Midterm Exam: 25% Final Exam: 30%
