This two-day short course introduces course participants to international standards for image/video and audio signal processing for multimedia, teleconferencing, and internet applications. The course includes descriptions of image and video coding algorithms as well as audio coding algorithms with some emphasis on those algorithms used in computer audio/video applications. Network issues will also be covered.
The course is designed for engineers and managers who need to understand the fundamentals behind multimedia image/video and audio standards. The course should be of particular interest to engineers who need to prepare for projects that involve analysis and implementation of teleconferencing algorithms.
In the first day of the course, speech and audio coding algorithms are examined including those embedded in telephony standards as well as those that are part of teleconferencing standards. In addition, network effects and quality of service issues are examined with regard to audio/video data streams. The second day of the course is spent on image and video coding algorithms with emphasis on those embedded in teleconferencing standards. In particular, the following are examined: GSM speech coding standards, code excited linear prediction, Aljebraic CELP, ITU G.728 low-delay CELP coder, The ACELP ITU G.729, CDMA EVRC (IS-127), True Speech, Audio coding topics include introduction to perceptual coding, the MPEG and AC-3 algorithms, and algorithms embedded in recent streaming audio. In addition still image and video compression standards are examined, i.e., image & video formats, color spaces, digital television formats, lossless encoding, huffman and arithmetic coding, DPCM, The JPEG standard, JPEG 2000, fundamentals of video compression, motion estimation & compensation, MPEG standards MPEG-1, MPEG-2, MPEG-4, MPEG-7, ITU-T Video Recommendations (H.261, H.263, H.263+).
