Abstract: Systems, methods, and devices of the various embodiments enable HTTP servers, such as HTTP servers providing segments to DASH clients according to the various embodiments, to pass incomplete versions of segments in response to segment requests from the DASH clients. The various embodiments may enable clients, such as DASH clients, to parse incomplete versions of segments.

Abstract: A device for receiving streaming data includes a broadcast or multicast middleware unit configured to receive the streaming data via a second service and a proxy unit configured to be disposed between the middleware unit and a client application, the proxy unit further configured to receive an indication of whether the streaming data is to be received via a first service or the second service, when the indication indicates that the streaming data is to be received via the first service: disable the middleware unit; and receive the streaming data via the first service, and when the indication indicates that the streaming data is to be received via the second service: activate the middleware unit to receive the streaming data via the second service, wherein the second service comprises at least one of a broadcast service or a multicast service; and receive the streaming data from the middleware unit.

Abstract: Distributed computing is disclosed in which a client device accesses a service announcement for a broadcast service in order to retrieve transport parameters describing a data transmission service. The client device obtains a refresh rate from the service description file, which is separate from the data transmission service, wherein the refresh rate relates to a frequency at which the data transmission service updates data in a data transmission provided by the data transmission service. The client device uses the transport parameters to access the data transmission to receive the data. Once the data is received, the client device will delay any subsequent access to the data transmission to get updated data for a delay time based at least in part on the refresh rate.
