A high-quality multimedia content delivery system is being developed for National Public Television of Poland, for delivery of live TV, Video-on-Demand and Audio-on-Demand with interactive access over broadband IP networks. While terrestrial, satellite and cable platforms are used for digital TV distribution, only a completely IP-based solution offers true interactivity, enabling the creation of new content access services.
PSNC has developed a scalable architecture Content Delivery System (CDS), in which Regional Data Centers (RDCs) can obtain content from content providers and then distribute it among themselves and to lower-level proxy/cache servers. During iGrid, one CDS node is set up in San Diego. Multimedia content is sent over a Gigabit link from RDC Poznan to San Diego, triggered by many simultaneous user requests.
