    Abstract: A method includes receiving at least an indication of a notification message through a first channel and receiving at least a part of the notification message through a second channel. The receiving at least an indication of a notification message may include a push-type delivery, and the receiving at least a part of the notification message may include a pull procedure. Alternatively, the receiving at least an indication of a notification message may include a poll-type delivery, and the receiving at least a part of the notification message may include a pull procedure.

    Abstract: Various embodiments of present invention relate to the synchronization of an SDP stream to the media stream. In various embodiments, the SDP-consuming application initiates a FLUTE receiver and retrieves new versions of the SDP file. The terminal also retrieves information from the RTCP layer about the current sender time. The sender time is indicated as an NTP timestamp in RTCP sender reports. The receiver indicates to the player that the new SDP file will be valid after some time period. Various embodiments of the present invention also cover the behavior of a terminal upon receiving an SDP update. Still further, various embodiments of the present invention provides for richer out-of-band ESG delivery than conventional systems, permitting more meaningful session updates.

    Abstract translation: 本发明的各种实施例涉及SDP流与媒体流的同步。 在各种实施例中，SDP消费应用程序启动FLUTE接收器并检索SDP文件的新版本。 终端还从RTCP层检索有关当前发送者时间的信息。 发送者时间在RTCP发送者报告中指示为NTP时间戳。 接收机向播放器指示新的SDP文件在一段时间后有效。 本发明的各种实施例还包括终端在接收到SDP更新时的行为。 此外，本发明的各种实施例提供比常规系统更丰富的带外ESG传送，允许更有意义的会话更新。

    Abstract: An improved system and method for implementing Multimedia Broadcast/Multicast Service (MBMS) handover during download delivery. Various embodiments of the present invention involve the use of the HTTP/1.1 “chunked” mode to deliver updates of the file delivery table (FDT) of a session in a push-like mode. In order to allow for push delivery of the contents of a FLUTE session, each FDT instance is encoded as one part of a multipart MIME message and is sent as a separate chunk. The receiver can interpret each of the separate chunks to extract the FDT instance from the chunks. The content type of each part of the message is set to “text/xml” or another MIMI type in order to indicate that the content is an FDT instance. After parsing the FDT instance and updating the FDT, the receiver is able to identify which files of the session are of interest and can perform a HTTP GET request to retrieve a specific file.
