Abstract: A system, method and a computer-readable medium having a computer-readable code embodied therein for providing content to a user, the method includes: generating, by a media provider, an instruction to fulfill a preliminary condition for receiving a second media conveying stream; transmitting the instruction to the user while also sending a first multicast media conveying stream; waiting for a preliminary condition fulfillment time period to lapse from an end of the transmitting of the instruction; and transmitting, by the media provider, the second media conveying stream towards the user, wherein the transmitting is initiated without being aware of an exact timing of a fulfillment of the preliminary condition.

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.

Abstract: A device and a method for providing programs to multiple end user devices. The method includes: providing to multiple end user devices, via an edge device, at least one type of media stream out of unicast media stream and a multicast media stream; wherein the at least one type of media stream convey a group of programs; receiving a request from a first end user device to view a first program that belongs to the group of programs; and selectively switching, 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.

Abstract: The invention provides a system and method for compensating for timing violations of a multiplex of at least two streams of media packets. The method includes the steps of: receiving the multiplex; associating a transmitter timing information to media packets; whereas the multiple media packet streams are associated to different time bases; transmitting the media packets and the associated transmitter timing information over a timing violation inducing communication channel to a receiver; receiving, by the receiver, the transmitter timing information and the media packets; providing at least one timing violation compensated stream of media packets in response to the transmitter timing information.
