CDN Research Institute

With the rapid development of Web 2.0 video sharing websites, illegal sharing of copyrighted content and the publishing of unhealthy content have been two emerging and outstanding problems for the whole industry. In our institute, the Special Interest Group of content security (SIGSEC)  focuses on exploring technologies in the areas of multimedia content copy detection, DRM, digital watermarking and multimedia search engine to build a working prototype of Internet multimedia content monitoring and management system, and further developing the system into a CDN service.

 Since 2008, implemented and commercially deployed a Video-on-Demand (VoD) streaming system over ChinaCache, which was used to provide Adobe Flash on-demand streaming service for official Olympic video web site and Chinese largest social network site during the period of 2008 Beijing Olympics. In our institute, the Special Interest Group of VoD streaming system (SIGVOD) is recently working on the system development, optimization and  measurement.
