Abstract: A device for retrieving media data includes one or more processors configured to retrieve media data from a first adaptation set including media data of a first type, present media data from the first adaptation set, in response to a request to switch to a second adaptation set including media data of the first type: retrieve media data from the second adaptation set including a switch point of the second adaptation set, and present media data from the second adaptation set after an actual playout time has met or exceeded a playout time for the switch point.

Abstract: A method for improving link efficiency in multicast transmissions is described. A data packet is sent to a multicast server. The data packet is processed. A copy of the data packet is transmitted from the multicast server to a multicast internet protocol (IP) address associated with one or more access terminals. The copy of the data packet is multicast to each of the one or more access terminals using a channel dedicated for multicast traffic that is associated with each of the one or more access terminals.
