METHOD AND APPARATUS FOR CONTROLLING THE BANDWIDTH OF SDV PROGRAMMING SUPPLIED TO AN EDGE DEVICE IN A SDV SYSTEM

摘要

A switched digital video (SDV) system is provided that includes an SDV managerfor coordinating SDV sessions requested by subscriber terminals associatedwith a servicegroup. An input is provided for receiving content to be broadcast during theSDVsessions. At least one edge device is provided for receiving transport streamsthat includeSDV programming provided by the input and for transmitting each transportstream overan access network to at least one of the subscriber terminals on one of aplurality of SDVchannels. The SDV manager is configured to (i) monitor bandwidth used by theedgedevice to provide the SDV programming to the service group and (ii) cause abit rate of atleast one SDV program supplied to the edge device to be adjusted based on themonitoredbandwidth usage.
