VISP: on Implementing a Video Streaming Protocol for the Internet

A recently proposed mechanism introduced a new approach to support interactive video streaming applications over the Internet. It acts on the video QoS in order to avoid possible problems caused by the network jitter. Simulations results proved the effectiveness of this mechanism. An exhaustive discussion on the implementation of this mechanism is the contribution of this paper. A client-server protocol, named VISP (VIdeo Streaming Protocol), is designed to support interactive video streaming applications over the Internet. VISP is not a video compression scheme and it is not a transport protocol, but an application protocol that controls the video transmission to provide interactivity. Several features have been added in order to complete the protocol and tests confirm that VISP is effective in supporting interactive video streaming applications over the Internet.
