    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: In one example, a client device for receiving information for streaming of media data includes a clock, and one or more processors configured to receive a media presentation description (MPD) for media content, wherein the MPD includes data indicative of wall-clock times at which the client device can retrieve data of the media content from a source device, and wherein the data indicates a synchronization method by which the client device is to synchronize the wall-clock times with the clock, synchronize the clock with the wall-clock times using the method indicated by the MPD, and request data of the media content from the source device using the synchronized clock. A server device or source device may form and provide such an MPD to a client device.

    Abstract: A server device for transmitting media data includes a first unit and a second unit. The first unit comprises one or more processing units configured to send descriptive information for media data to the second unit of the server device, wherein the descriptive information indicates a segment of the media data or a byte range of the segment and an earliest time that the segment or the byte range can be delivered or a latest time that the segment or the byte range of the segment can be delivered, and send the media data to the second unit. The second unit thereby delivers the segment or the byte range of the segment according to the descriptive information (e.g., after the earliest time and/or before the latest time).
