Abstract: Embodiment systems, methods, and devices enable data streams of a broadcast service to be carried in multiple communication sessions in any transport protocol providing file transport information and the transmission of objects, an example of which is File Delivery Over Unidirectional Transport (“FLUTE”). A session description may include a category attribute indicating the type of data carried in such a protocol session. A schedule fragment may include references to a session description for each such protocol session associated with a service. A common listing of configuration parameters may be generated for all such protocol sessions associated with a service. A different listing of configuration parameters may be generated for each such protocol session associated with a service. A flag setting in a diary file may indicate one or more such protocol session associated with a service over which in-band update fragments may be broadcast.

Abstract: An emergency notification service is described that is delivered using an evolved multimedia broadcast-multicast service (eMBMS). An emergency notification is sent out to user equipment (UE) in affected areas. In response to receiving the emergency notification, the UE searches the appropriate emergency multicast service acquisition information for multiple potential types of available emergency content that is provided by the eMBMS system in the network and tunes to the eMBMS to receive the emergency content. In selected aspects, the transmitted information, including the notifications and content may be scrambled using the same cell ID for each of the cells transmitting the same content. This improves the quality of the transmitted signals allowing for more reliable receipt and decoding by the receiving UEs.

Abstract: A system and methods for determining whether to participate in reception reporting procedures for an eMBMS service. Multiple applications on a receiver device can consume the same file download or streaming eMBMS service, and can have conflicting opt in/opt out settings for reporting in middleware. Algorithms are provided that take into account the different opt statuses of applications, and allow middleware components to determine whether to log reception metrics for a service and/or whether a reception report should be uploaded after a service session of the service.

Abstract: A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.

Abstract: A device for processing media data includes one or more processors configured to receive a session description protocol (SDP) message including an attribute that defines a time-shifted buffer (TSB) depth, determine an amount of memory for the TSB based on a value of the attribute, allocate the determined amount of memory to the TSB, and store at least a portion of media data associated with the SDP message in the TSB. The value for the attribute may signal the depth of the TSB in terms of playback time in seconds. The attribute may leverage the extensibility of SDP messages through, for instance, “a=” lines. For instance, the TSB depth attribute may correspond to an “a=tsb-length:” attribute.

Abstract translation: 用于处理媒体数据的设备包括被配置为接收包括定义时移缓冲器（TSB）深度的属性的会话描述协议（SDP））消息的一个或多个处理器，基于TSB的值来确定TSB的存储量 该属性将确定的存储量分配给TSB，并将与SDP消息相关联的媒体数据的至少一部分存储在TSB中。 该属性的值可以以播放时间（秒）表示TSB的深度。 该属性可以通过例如“a =”行来利用SDP消息的可扩展性。 例如，TSB深度属性可以对应于“a = tsb-length：”属性。
