1. A method for distributing IP video comprising:
- transmitting an optical data stream in a designated optical band to an optical network terminal (“
ONT”
), wherein the optical data stream comprises a broadcast IP video signal provided as a packetized video overlay;
converting the optical data stream to an electrical data stream at the ONT; and
transmitting the electrical data stream to a subscriber.

25. A system for distributing video, the system comprising:
-
a video head end connected to receive a broadcast IP video data stream and convert the received data stream from an electrical signal to an optical signal in a first optical band;
an optical amplifier (“
OA”
) for amplifying optical signals received from the video head end;
a wave division multiplexer (“
WDM”
) for combining the amplified broadcast IP video data stream from the OA with IP data and voice signals in a second optical band; and
a distributive optical network for transmitting the combined optical signal to an optical network terminal (“
ONT”
) at a subscriber premises, wherein at the ONT, the broadcast IP video data signals are recovered from the combined optical signal, converted back to an electrical signal, and transmitted to subscriber equipment. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
