Abstract: This paper is to review several important signal processing issues related to video streaming, and puts them in the context of a client-server based media streaming architecture on the Internet. Such a context is critical, a number of solutions proposed by signal processing researchers are simply unrealistic for real-world video streaming on the Internet. We further identify a family of viable solutions and evaluate their pros and cons. Finally, we identify the promising areas of research that have been received less attention and point to the problems to which a better solution is eagerly sought by the industry.
