Sun Reference Architecture for IPTV

  1. 1. Sun™ Reference Architecture for IPTV Integrated VoD and nPVR Infrastructure < Fundamental changes are taking place in the ways that people view television and video. Through Video on Demand (VoD), network personal video recording (nPVR), pay per view (PPV), and other technologies, viewers are taking an active role in what, where, and when they watch. These trends offer considerable promise to telecommunications, cable, and wireless providers, as they seek to attract and retain customers with new IPTV services. Based on the massively scalable Sun™ Streaming System, the Sun Reference Architecture for IPTV integrates key partner technologies to provide an end-to-end video services infrastructure. Delivering effective IPTV Beyond the capabilities of individual video No matter what the promise, video services servers, delivering video over IP also requires infrastructure remains challenging to inte- integration of specialized technologies: grate for many organizations.
