A method for providing live adaptive bitrate video content to a client device using a multicast-to-unicast-ABR proxy, the method comprising: responsive to the client device tuning to a channel or requesting a change in profile, receiving a request, from the client device located inside end-user household, via unicast for ABR video content from the multicast-to-unicast-ABR proxy based on resource constraints; requesting, by the multicast-to-unicast-ABR proxy, a burst of video fragments for a channel using a selected profile from a distribution server, wherein the burst of video fragments to be delivered via unicast; receiving, via unicast, an aggregate manifest and the burst of video fragments corresponding to the requested ABR video content, at the multicast-to-unicast-ABR proxy from a distribution server, wherein the multicast-to-unicast-ABR proxy sets a period of the aggregate manifest to a value according to when it is anticipated to have a new fragment re-assembled from the burst of video fragments and re-generation of new profile manifest with fragment listed in each profile manifest until all fragments listed in the aggregate manifest are available; providing, from the multicast-to-unicast-ABR proxy, video corresponding to the requested ABR video content from the burst of video fragments to the client device via unicast; responsive to the burst of video fragments being completed, the multi-to-unicast-ABR proxy requesting, to a Multicast Replication point, to join a multicast for the channel, the multicast using the selected profile; receiving, via multicast, a multicast stream containing video fragments corresponding to the requested ABR video content at the multicast-to-unicast-ABR proxy from the distribution server; and providing, from the multicast-to-unicast-ABR proxy, video corresponding to the requested ABR video content from the multicast stream containing video fragments to the client device via unicast. responsive to the client device tuning to a channel or requesting a change in profile, receiving a request, from the client device located inside end-user household, via unicast for ABR video content from the multicast-to-unicast-ABR proxy based on resource constraints; requesting, by the multicast-to-unicast-ABR proxy, a burst of video fragments for a channel using a selected profile from a distribution server, wherein the burst of video fragments to be delivered via unicast; receiving, via unicast, an aggregate manifest and the burst of video fragments corresponding to the requested ABR video content, at the multicast-to-unicast-ABR proxy from a distribution server, wherein the multicast-to-unicast-ABR proxy sets a period of the aggregate manifest to a value according to when it is anticipated to have a new fragment re-assembled from the burst of video fragments and re-generation of new profile manifest with fragment listed in each profile manifest until all fragments listed in the aggregate manifest are available; providing, from the multicast-to-unicast-ABR proxy, video corresponding to the requested ABR video content from the burst of video fragments to the client device via unicast; responsive to the burst of video fragments being completed, the multi-to-unicast-ABR proxy requesting, to a Multicast Replication point, to join a multicast for the channel, the multicast using the selected profile; receiving, via multicast, a multicast stream containing video fragments corresponding to the requested ABR video content at the multicast-to-unicast-ABR proxy from the distribution server; and providing, from the multicast-to-unicast-ABR proxy, video corresponding to the requested ABR video content from the multicast stream containing video fragments to the client device via unicast.
