Abstract
Embodiments are directed to systems and methods for delivering broadcast television (TV) using an Internet Protocol (IP) network. The IPTV system and methods use real-time routing servers to unicast and/or multicast of broadcast television programs. The IPTV system and methods may enable advertisers to insert local commercials into national or international television broadcasts. The IPTV system and methods offer network-based time-shifting of broadcast television programming rather than personal video recorder (PVR)-based time-shifting. The IPTV system and methods may provide scalable video on-demand (VOD) by multicasting video content and dynamically determining whether to speed up or slow down a bit stream to catch up to or wait for the previous or next multicast of the video content. The IPTV system and methods also may enables interactive television programming whereby a viewer may be permitted to exchange video with a television program and have that video displayed.
