摘要：An IPTV is a system used to deliver television services to the consumers who are registered subscribers for this system. This delivery of digital television is made possible by using Internet Protocol over a broadband connection, usually in a managed network rather than the public Internet to preserve quality of service guarantees. In addition to this there is provision to include Internet service such as web access and Voice over Internet Protocol (VoIP). Currently, digital television is gradually replacing analogue TV. Although these digital TV services can be delivered via various broadcast networks (e.g., terrestrial, cable, satellite), Internet Protocol TV over broadband telecommunication networks offers much more than traditional broadcast TV. This paper first provides an overview of a typical IPTV network architecture and some basic server architecture design. This paper further argues that the availability of larger buffers in the network enables IPTV to better offer new services (in particular, timeshifted TV, network personal video recorder, and videoondemand) than the competing platforms.
