The advent of social networking applications, media streaming technologies, and synchronous communications has created an evolution towards dynamic shared media experiences. In this new model, geographically distributed groups of users can be immersed in a common virtual networked environment in which they can interact and collaborate in real- time within the context of simultaneous media content consumption. In this environment, intra-stream and inter-stream synchronization techniques are used inside the consumers’ playout devices, while synchronization of media streams across multiple separated locations is required. This synchronization is nown as multipoint, group or Inter-Destination Multimedia Synchronization (IDMS) and is needed in many applications such as social TV and synchronous e-learning. This survey paper discusses intraand inter-stream synchronization issues, but it mainly focuses on the most well-known IDMS techniques that can be used in emerging distributed multimedia applications. In addition, it provides some research directions for future work.

Synchronization is an important aspect of the design and implementation of distributed multimedia database systems. In this chapter, we first examine the models that have been proposed in the literature to specify multimedia and multi-stream synchronization and the methods to implement synchronization mechanisms in distributed multimedia database systems. Their strengths and limitations have been compared, and the issues about time uncertainty and interactivity in multimedia and multi-stream synchronization specification and implementation are discussed. Moreover, we use an example to show how to incorporate a synchronization agent into a distributed multimedia database system. Finally, we discuss the trend of future research and development of this topic.
