    Abstract: Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.

    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 proxy unit is configured to obtain mapping information that maps an identifier for media data to a resource location based on a service for retrieving the media data, wherein the service defines at least one of a plurality of types of transports for transporting the media data, receive a request for the media data from an application service client, determine whether the service is available, and, when the service is available, cause the application service client to receive the media data from a unit that receives the media data using the service from the resource location, based on the mapping information. In this manner, the application service client may receive media data from the unit (e.g., a middleware unit), which then receives the media data using a service that defines transport according to, e.g., broadcast or multicast transport, or another fashion (e.g., unicast) if the defined transport is unavailable.

    Abstract translation: 代理单元被配置为获得基于用于检索媒体数据的服务将媒体数据的标识符映射到资源位置的映射信息，其中，所述服务定义用于传送媒体数据的多种类型的传输中的至少一种， 从应用服务客户端接收对媒体数据的请求，确定服务是否可用，并且当服务可用时，使得应用服务客户端从接收媒体数据的单元接收媒体数据，使用来自 资源位置，基于映射信息。 以这种方式，应用服务客户端可以从单元（例如，中间件单元）接收媒体数据，该单元然后使用根据例如广播或多播传输或另一种方式定义传输的服务来接收媒体数据（例如， ，单播）如果定义的传输不可用。
