Abstract
A scheme for providing programs to multiple end user devices. Two types of media streams that convey a first group of programs are provided to multiple end user devices via an edge device. The two types of programs include a unicast media stream and a multicast media stream. When a request from a first end user device to view a first program that belongs to the first group of programs is received, a type of a media stream that conveys the first program to a second end user device is selectively switched, in response to bandwidth constraints imposed on a communication path coupled to the edge device.
