Selective unicast requests for broadcast and multicast delivery of media data

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.
