Abstract:
A system for the end-to-end delivery of digital television signals. In a preferred embodiment a digital television signal is: received from production equipment, typically in HD format at approximately 1.4 gigabits per second (Gbps); the received signal is transmitted to a venue point-of-presence; converted for transmission via a 270 Mbps local loop; transmitted to a fiber network point of presence/video service edge; packetized into TCP/IP packets in a video gateway; and routed to one or more destination addresses via the fiber network; received at one or more video service edge destinations; converted to a digital television format, typically SDI; and either transmitted via a second 270 Mbps local loop for delivery to a customer site and subsequent conversion to a 1.4 Gbps HD signal, or converted directly to a 1.4 Gbs HD signal at the receiving video service edge.
