摘要： Systems and methods for constructing multiple-level filtering information that is applicable for an aggregate of multiple messages. According to various embodiments, a set of filtering values is constructed for a first level as a union of all filter values of the filtering criteria that belong to the intersection set of filter criteria. At the receiver side, the aggregate transport object is filtered based on the first-level filtering information as a first process. The first-level filtering information may be separate of the transport object. If the transport object is not discarded after first-level filtering, then the second-level filtering information, which requires the processing of the transport object, is used to fetch the messages in the bundle.

摘要： A system and method for providing MBMS content distribution using unicast bearers. According to various embodiments, MBMS download user services are delivered to pieces of user equipment by delivering a FLUTE file delivery table via an OMA Push message. One of a number of different additional actions may be used in the delivery of the MBMS download user services. These actions include (1) making a single HTTP GET request using simple URL-encoding format to retrieve all files of the FDT; (2) making a single HTTP GET request using 'group' field of FDT in URL- encoding to retrieve a logical group of files of the FDT; (3) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (4) making serialized HTTP GET requests where each HTTP GET request retrieves at least one file of the FDT; (5) making pipelined HTTP GET requests where each HTTP GET request retrieves at least one logical group of files of the FDT; (6) making serialized HTTP GET requests where each HTTP GET request retrieves al least one logical group of files of the FDT; (7) delivering the servicelD of the MBMS user service in the above mentioned OMA PUSH message but not including the servicelD in the FLUTE FDT; (8) an HTTP request to de-register the MBMS UE from the BM- SC for stopping the unicast delivery of the MBMS download user service; and (9) delivering the FDT Instance ID of the FDT Instance in an OMA Push message,

摘要： Various embodiments provide for the splitting of a notification message to a user, where the notification message enables at least one of interactivity and delivery of information associated with a media broadcast service. A first component of the notification message carries media content and is transmitted utilizing a file delivery protocol, such as FLUTE, HTTP, and OMA-PUSH. A second component of the notification message carries any synchronization information associated with the interactivity and the delivery of the information associated with the media broadcast service. The second component of the notification message can be transported in an RTP payload via RTP to allow for accurate synchronization of the notification message with a media stream of the media broadcast service containing the media content.

摘要： 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.

摘要： Various methods for generating and handling streaming media metrics are provided. One example method includes receiving media presentation data, where the media presentation data is associated with a presentation of streaming media, and determining, based on at least the media presentation data, one or more quality of experience metrics that are to be reported. The example method further comprises generating a metric value corresponding to each of the one or more quality of experience metrics, and causing the metric value corresponding to each of the one or more quality of experience metrics to be reported. Similar and related example methods and example apparatuses are also provided.

摘要： A method, apparatus, system and computer program product are provided to facilitate dynamic media streaming. In this regard, a server may receive a transport protocol for at least the portion of the media file indicating that at least a portion of the media file is to be streamed to a content consumption device requesting the media file. In response, a plurality of fragments to be transmitted to the content consumption device may be determined based upon the transfer protocol request and the plurality of fragments may then be transmitted to the content consumption device in response to the transfer protocol request.
