Abstract: An example server unit for retrieving media data on behalf of a client device, the server unit comprising: a memory configured to store media data; and a processing system implemented in circuitry and configured to: receive, for the client device, configuration data for a media streaming session for a media presentation to be received via broadcast or unicast, the configuration data indicating that personalization data for the media presentation can be selectively exchanged using a unicast transmission; determine that at least a portion of the personalization data is to be exchanged; and exchange the at least portion of the personalization data via a unicast transmission. The server unit may be a server device separate from the client device or a proxy server included in a middleware unit of the client device.

Abstract: An example device for retrieving media data includes a memory configured to store media data; and a processing system including a decoder implemented in circuitry, the processing system being configured to: retrieve a manifest file indicating a plurality of network locations for at least a first segment of media data and a second segment of the media data, each network location among the plurality of network locations being hosted by a separate physical server device; retrieve at least a first portion of the first segment from a first network location of the plurality of network locations; retrieve at least a second portion of the second segment from a second network location of the plurality of network locations; and provide the at least first portion of the first segment and the at least second portion of the second segment to the decoder.

Abstract: Example in-band delay measurement techniques are described. An example first computing device transmits, to a second computing device, a first data packet, the first data packet including a first time indicator and at least one header extension element. The at least one header extension element includes a header extension element header, the header extension element header having a length of at least one byte. The first computing device receives, from the second computing device, a second data packet, the second data packet including a second time indicator. The first computing device determines a data packet delay associated with the first data packet based on the first time indicator and the second time indicator and transmits an indication of the data packet delay to at least one of the second computing device or a third computing device.
