    Abstract: In one example, a device includes one or more processors configured to receive a first segment of media data, wherein the media data of the first segment comprises a stream access point, receive a second segment of media data, wherein the media data of the second segment lacks a stream access point at the beginning of the second segment, and decode at least a portion of the media data of the second segment relative to at least a portion of data for the first segment. In this manner, the techniques of this disclosure may be used to achieve a Low Latency Live profile for, e.g., dynamic adaptive streaming over HTTP (DASH).

    Abstract: Systems, methods, and devices of the various embodiments enable evolved Multimedia Broadcast Multicast Service (“eMBMS”) network sharing, content sharing, and roaming. The various embodiments may enable Multimedia Broadcast Multicast Service (“MBMS”) service continuity across different public land mobile networks (“PLMNs”) by associating the same MBMS services providing identical content in different PLMNs with each other. In an embodiment, service discovery may be provisioned to a receiver device when or after the receiver device is attached to a PLMN. In an embodiment, content sharing across different PLMNs may be supported by a user service description indicating the different temporary mobile group identifiers (“TMGIs”) of the same service across different PLMNs. In another embodiment, content sharing across different PLMNs may be supported by a user service description indicating the same TMGI for the same service across different PLMNs. In an embodiment, MBMS keys may be shared across PLMNs.

    Abstract translation: 各种实施例的系统，方法和设备实现了演进的多媒体广播多播服务（“eMBMS”）网络共享，内容共享和漫游。 各种实施例可以通过将在不同PLMN中提供相同内容的相同MBMS服务彼此相关联来实现跨越不同公共陆地移动网络（“PLMN”）的多媒体广播多播服务（“MBMS”）服务连续性。 在实施例中，服务发现可以在接收机设备附接到PLMN时或之后被提供给接收机设备。 在一个实施例中，跨不同PLMN的内容共享可以由指示跨越不同PLMN的相同服务的不同临时移动组标识符（“TMGI”）的用户服务描述来支持。 在另一个实施例中，跨越不同PLMN的相同服务的用户服务描述可以支持跨不同PLMN的内容共享，指示相同服务的相同TMGI。 在一个实施例中，可以在PLMN之间共享MBMS密钥。

    Abstract: A method for blackout, retune and roaming enforcement in a cellular network multimedia distribution system. The method includes the steps of receiving a plurality of service regions in the cellular network multimedia distribution system; determining an affiliation of the client with one of the service regions in the plurality of service regions; and, processing a service region specific message based on the affiliation. An apparatus, as well as a computer readable medium having instructions stored thereon, the stored instructions, when executed by a processor, cause the processor to perform the method are also disclosed.

    Abstract: Systems and methods are provided for mitigating interference in a wireless network to facilitate network performance. In an aspect, a method for transmitting wireless data packets is provided. The method includes receiving data packets from a wireless distribution network. The data packets are analyzed to determine if a subset of the data packets are to be suppressed in view of transmitter signal conditions and substituting null packets for the subset of data packets if the subset of data packets are determined to be suppressed.

    Abstract: Various aspects include methods for facilitating digital rights management (DRM) within an electronic device. Various aspect methods may include receiving a first broadcast message, storing a DRM license object extracted from the DRM license-related message, receiving a DRM license request message generated by a content decryption module (CDM) of the electronic device, determining that the DRM license object is associated with the encrypted content received by the electronic device during the broadcast content session based on the identification information included in the DRM license request message received from the CDM of the electronic device, and sending the DRM license object to the CDM of the electronic device. The first broadcast message may be a DRM license-related message generated by a broadcast server. The DRM license request message may include identifier information associated with encrypted content received by the electronic device during a broadcast content session.

    Abstract: In a first configuration, a UE receives, from a service provider, a certificate authority list. The certificate authority list is at least one of integrity protected or encrypted based on a credential known by the UE and the service provider and stored on a smartcard in the UE. The UE authenticates a server using the received certificate authority list. In a second configuration, the UE receives a user service discovery/announcement including a reception report configuration and an address of a server. The UE sends a protected reception report to the server based on the reception report configuration. In a third configuration, the UE receives a protected broadcast announcement and communicates based on the broadcast announcement. The broadcast announcement is at least one of integrity protected or encrypted based on a credential known by the UE and stored on a smartcard in the UE.
