    Abstract: A user equipment (UE) includes a communication unit and a processor. The communication unit communicates with a server. The processor transmits a hypertext transfer protocol (HTTP) streaming session request including an indication that the UE supports Motion Picture Experts Group (MPEG) media transport (MMT) to the server and receives a description of MMT service components including an indication that the server supports MMT. The processor also migrates the UE to a MMT streaming session, selects at least one service component from the MMT service components, transmits a selection message to the server, and receives media corresponding to the selected at least one service component.
