A multicast adaptive bit rate receiver is employed delay issuance of specific unicast HTTP adaptive bit rate media segment requests while waiting for receipt of stripped multicast media segments from a multicast server. An HTTP proxy may create a new internal state that waits for subsequent media segment URL requests. As the stripped multicast media segments are received, the HTTP requests queued in the proxy may be delivered to the local ABR client.
