A method for providing live adaptive bitrate (ABR) 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. <EOS>
