User- and content-aware object-based video streaming over the Internet

This paper presents a new scheme for efficient MPEG4 video transmission over the Internet that provides differentiated services (diff-serv). The scheme has three new elements: (1) smart packetization scheme which distinguishes different types of MPEG4 data streams; (2) object-based bit rate control and adaptation corresponding to users' interactions and selections; (3) selective dropping of packets that takes advantage of differentiated classes in diff-serv. Experiment was conducted on the Microsoft's IPv6 platform where an adaptive MPEG4 video streaming system was developed to verify our proposed approach. Experimental results show that our proposed scheme provides must improved QoS and capability for object-based user interactivity.
