Objective

The goal of this course is to provide a good balance between theoretical concepts and practical solutions for transmission of audiovisual services over IP networks : Internet and mobile IP systems. The course covers the analysis of the whole transmission chain from source coding (audio & video coding) to channel coding and transmission (DVB, RTP, …). Network resource allocation and quality of service optimization are addressed. Finally, several labs are proposed to practically evaluate the most advanced solutions and concepts.
