1. A method for delivering adaptive bit rate media over a broadband network comprising multiple towers and gateways, the method comprising:
providing an emulated adaptive bit rate server;
intercepting an adaptive bit rate playlist get request by the emulated adaptive bit rate server;
when a requested video segment is flowing at one of the multiple towers, providing a modified adaptive bit rate playlist response to the adaptive bit rate playlist get request, wherein the modified adaptive bit rate playlist response identifies the tower as a source for the requested video segment;
instantiating a plurality of dynamic downstream adaptive bit rate servers to serve the modified adaptive bit rate playlist response, by:
transmitting, by the emulated adaptive bit rate server to the tower, an accelerated buffering command to instantiate one of the dynamic downstream adaptive bit rate servers; and
while the one dynamic downstream adaptive bit rate server is being instantiated, transmitting, by the emulated adaptive bit rate server, a predetermined amount of transport stream segment data to the media player.
