Abstract: Apparatuses may perform and methods may include receiving a digital broadcast signal that includes a physical layer pipe identified by a predetermined identifier indicating that the physical layer pipe includes service guide bootstrap information. The bootstrap information may identify one or more service guides available for download. The physical layer pipe may include header information that identifies one or more other physical layer pipes containing portions of the service guides identified in the bootstrap information. Based on the bootstrap information and header information, a selected service guide is retrieved and presented to a user.

Abstract: Apparatuses may perform and methods may include: receiving a digital broadcast signal that includes an Electronic Service Guide (ESG); extracting and assembling the ESG; extracting from the ESG signaling information which links one or more services in an upper level layer of a broadcast protocol to a physical layer of the broadcast protocol. Based on the signaling information, one or more services from a broadcast system may be accesses.

Abstract: Apparatuses may perform and methods may include receiving a broadcast signal that includes a physical layer pipe identified by a predetermined identifier indicating that the physical layer pipe includes service guide bootstrap information. The bootstrap information may identify one or more service guides available for download. The physical layer pipe may include a header that includes version values that identify changes in signaling data and changes in the service guides. Based on receiving the header only, an apparatus may determine whether the signaling data and/or service guides previously stored in the apparatus need to be updated.

Abstract: Apparatuses may perform and methods may include: receiving a digital broadcast signal that includes layer 2 (L2) signaling information carried within a Real-time Protocol (RTP) layer; locating a physical layer pipe (PLP) carrying local multiplex information of the L2 signaling information and a PLP carrying other multiplex information of the L2 signaling information; and extracting the local multiplex information and the other multiplex information from the respective PLPs.

Abstract: Components of a transmitted service delivering multiple versions of content are mapped to streams carrying data for those multiple versions. The data streams are encapsulated into User Datagram Protocol (UDP) packets; the UDP destination port fields of the packets are given component-identifying values. A user equipment (UE) receiving the transmitted service identifies desired components based on the UDP destination port field values. The UE further encapsulates desired component UDP packets into Internet Protocol (IP) packets, and may assign component-identifying values to fields of the IP packets (e.g., the IP source address and/or IP destination address).

Abstract: In accordance with an example embodiment of the present invention, a method and apparatus are described for mapping one or more layers of a scalable media stream to at least one physical layer pipe of a transmission. Information related to the mapping is transmitted. Also, the one or more layers are transmitted in the at least one physical layer pipe. Further, a method and apparatus are shown for receiving data in a transmission in at least one physical layer pipe. Information is received in related to a mapping of one or more layers of a scalable media stream to the at least one physical layer pipe. Based on the received information related to the mapping, the one or more layers of the scalable media stream in the received data are identified.
