    Abstract: An example client device includes a middleware unit for receiving media data either via a broadcast service or a unicast service, depending on whether the broadcast service is available. The client device also includes a streaming client, such as a Dynamic Adaptive Streaming over HTTP (DASH) client. The DASH client sends requests to retrieve media data via the middleware unit. The middleware unit may cache media data received via the broadcast service, such that even when the broadcast service is not active, if the streaming client requests media data that was previously received via the broadcast service, the middleware unit may provide the media data to the streaming client from the cache, rather than requesting the media data from an external server device specified in the request from the streaming client.

    Abstract translation: 示例性客户端设备包括用于经由广播服务或单播服务来接收媒体数据的中间件单元，这取决于广播服务是否可用。 客户端设备还包括流客户端，例如动态自适应流HTTP over（DASH）客户端。 DASH客户端通过中间件单元发送请求来检索媒体数据。 中间件单元可以缓存经由广播服务接收到的媒体数据，使得即使当广播服务不活动时，如果流客户端请求先前经由广播服务接收到的媒体数据，则中间件单元可以将媒体数据提供给 而不是从来自流客户端的请求中指定的外部服务器设备请求媒体数据。

    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。

    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。

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), that a first condition for performing a handover from the first RAT to a second RAT is satisfied. The UE may determine that the second RAT would trigger a fallback to a third RAT after the handover from the first RAT to the second RAT and that a second condition for performing a handover from the third RAT to the first RAT is satisfied. The UE may refrain from performing the handover from the first RAT to the second RAT based at least in part on the determination that the second RAT would trigger the fallback and the determination that the second condition is satisfied. Numerous other aspects are provided.
