Abstract
Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A dynamic MPD can be supplemented by offline descriptor information transmitted OTA at display time so that the descriptor information, e.g., language information, captioning information, and the like, can be immediately presented on a UI.
