Eligibility:

For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

Knowledge of signals and systems (transforms and filtering). Basic knowledge of digital communications or data communications is advantageous.

Aim

There is a growing interest in transporting compressed multimedia, particularly speech, image and video, through Internet and wireless communication networks. Different from conventional data transmission, compressed video and multimedia signals usually require large bandwidths, and are prune to network distortions such as packet losses and delay due to congestion in the networks. Re-transmission is often not possible due to the constraint of real-time processing.
This course will address multimedia and video data compression, and transmitting these compressed data through Internet and wireless networks. Students will gain basic knowledge on multimedia signal characterization and compression; on transmission media, losses and protection for compressed multimedia/videos, and on network-adaptive multimedia/video communications. Further, students will acquire some insights into the current state-of-the-art of the technology specially related to transmitting compressed multimedia and videos. The course will be a combination of lectures and laboratory experiments where students will gain first hand experiences.

Learning outcomes (after completion of the course the student should be able to)

· explain the limitations of current Internet protocol hierarchy for transmitting multimedia data
· describe some basic methods used in image and video compression standards
· describe packet loss models and compute packet loss probabilities in multimedia communications
· explain the advantages and disadvantages of joint source and channel coding, network-adaptive coding, for transmitting packet videos
· extend previous one dimensional signal processing knowledge, especially on transformations and filters to 2D and multidimensional cases, and apply them to image and video compression
· choose optimal coding strategies for joint source and channel, or end-to-end video communication system by using some distortion functions
· relate visual perception of quality videos with coding strategy selections
· justify simplified assumptions of video properties, and essential issues on packet losses for end-to-end video communications.

Content

Multimedia signal characterization and compression
o Models and compression methods for speech/audio signals;
o Fundamentals of image and video compression: energy compaction and motion compensation;
o Fundamentals of image/video compression and related standards;
Transportation media, protocols, losses and protection;
o IP networks for multimedia;
o wireless networks for multimedia;
o Packet losses vs. bit losses;
o Error protection and resilience for multimedia packets
Network-adaptive multimedia communications.
o End-to-end performance optimization for IP videos
o Layered coding and progressive transmission;
o Multiple description coding and multicast;
o Error concealment; We aöso discuss some environmental friendly approaches of communications, e.g. teleconferencing, where real-time exchange of information is carried out among people who are not in the same physical space.

Organisation

The course consists of lectures, basic laboratory exercises, and home work for obtaining first hand experiences.

Literature

Compressed video communications, by Abdul H. Sadka, ISBN: 0 470 84312 8


(e-book is available in Chalmers' Library.)

Examination

The final grade is based on scores from four laboratory exercises and a written exam that covers some basic concepts and theoretical issues. The laboratory exercises and the project are mandatory.
