Multimedia Networking and Video Streaming

Introduction:

   ADVANCES in computers, networking, and communications have created new distribution channels and business opportunities for the dissemination of multimedia content. Streaming audio and video over networks such as the Internet, local area wireless networks, home networks, and commercial cellular phone systems has become a reality and it is likely that streaming media will become a mainstream means of communication. Despite some initial commercial success, streaming media still faces challenging technical issues, including quality of service (QoS) and cost effectiveness. For example, the emerging streaming architectures such as peer-to-peer (P2P) networks and wireless ad hoc networks have also raised many interesting research challenges.
  The goal of the group is to research and develop advanced and efficient techniques for video streaming delivery. To achieve the goal, various networking and multimedia delivery issues will be addressed. We also develop a peer to peer based live video streaming system to prove and demonstrate the concepts of our results.

Content:

     Multicast is a fundamental and important mechanism to deliver scalable multimedia contents. Unfortunately the Internet nowadays still cannot support global multicast. In recent years, peer-to-peer (p2p) based multimedia streaming has aroused much interest both in research communities and in industries. In a p2p streaming system, multimedia contents should be delivered to a large pool of distributed users with low delay and high quality. Fueled by advances in networking and compression technologies, p2p multimedia streaming has experienced initial deployment success for applications such as Internet TV, video conferencing, and surveillance. A scalable peer-to-peer multimedia system should support many hosts, possibly in excess of hundreds or even millions, with diverse heterogeneity in bandwidth, capability, storage, network, and mobility. It should also be able to support various applications and file formats under dynamic user arrival and departure, frequent host failures and unavailability, and unpredictable network traffic and congestion. To achieve these goals, it is particularly important to address the challenges in architecture design, network/transport support, resource discovery and content delivery mechanisms.
  Therefore, the group has designed and implemented two peer-to-peer based live video streaming systems, providing service over campus network and global Internet. For the first experience, a multi-sender based hierarchical explicit overlay structure was deployed to demonstrate the scalability of peer to peer concept. Then, to address the problems of single point failure and dedicated server workload, the group advocated gossip-based distributed membership management and with the help of efficient ‘push+pull’ streaming mechanism, the system has been deployed by CCTV for live broadcasting Spring Festival Evening Show. Most excitingly, it was evidenced this architecture could scale to reliably support as many as 15,239 concurrent users with support of only one common streaming server.
  Now the group proceeds ongoing research work along several arenas, including nodes heterogeneity and scalable coding, media on demand service, efficient video coding schemes, secure multicast and incentive mechanisms
