Method and device for providing programs to multiple end user devices

A device for providing multiple programs, the device comprises an output interface adapted to:

• (i) provide to an edge device at least one type of media stream out of a unicast media stream and a multicast media stream;
• wherein the at least one type of media stream convey a group of programs;
• wherein the media streams are provided via the edge device to multiple end users;
• (ii) receive a request from a first end user device to view a first program that belongs to the group of programs;
• and
• a controller adapted to determine when to selectively switch, in response to bandwidth constraints imposed on a communication path coupled to the edge device, a type of a media stream that conveys the first program to a second end user device.
