Abstract: Systems, methods, and devices of the various embodiments enable managing a start time of media content in a media receiver device. A processor of the receiver device may receive media content labeled with a transmission time from a sending device. The processor may determine a service construction delay of the media content of the media content. The processor may determine a time offset of the media content based on the service construction delay. The processor may deliver the media content to a streaming media client in the receiver device using the time offset.

Abstract: An example device for processing video data includes a memory configured to store an omnidirectional video stream, and a processor implemented in circuitry and configured to process (e.g., encode, transmit, receive, or decode) a first frame of a set of file format samples of the omnidirectional video stream, the set of file format samples referring to a sample entry, the first frame having a first region-wise packing scheme, and process a second frame of the set of file format samples referring to the sample entry, the second frame having a second region-wise packing scheme different than the first region-wise packing scheme. In this manner, a single omnidirectional video bitstream may include an entire virtual reality (VR) video content with most-requested regions being optimized with a largest number of color samples per unit of area.

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: An over-the-air (OTA) broadcast middleware unit is configured to receive aggregated session description data for a plurality of sessions, wherein each of the sessions transports media data related to common media content, and wherein each of the sessions is transmitted as part of an OTA broadcast, and extract at least some of the media data from the OTA broadcast based on the aggregated session description data. The OTA broadcast middleware unit may further deliver the extracted media data to a streaming client, such as a Dynamic Adaptive Streaming over HTTP (DASH) client.

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).
