SYNCHRONIZATION PROTOCOL FOR HIGH-QUALITY AND SINGLE-POINT PLAYOUT MULTIMEDIA APPLICATIONS

A primary requirement in multimedia applications is the guarantee of u ser level services performance, such as data stream synchronization an d service quality control. Necessary control mechaniSMS and network st rategies have to be installed to satisfy this requirement. However, ap plications with a different user emphasis require different controllin g strategies, which in turn set up the requirements for both the under lying network and upper layer application control. How to analyse vari ous user demands and effectively implement them is the key to success. This paper describes some concerns in multimedia synchronization, and arising from the discussion, a synchronization protocol for high qual ity and single-point playout applications is proposed,
