Abstract: A user equipment (UE) participates in a coordinate-sharing communication session with at least one other UE that is arbitrated by a server (e.g., another UE participating in the session or an independent server). The UE displays a given visual representation of media content associated with the coordinate-sharing communication session. In an embodiment, the UE receives user input that indicates a selection of at least one coordinate of the given visual representation, and reports the coordinate selection(s) to the server via a coordinate packet. During the coordinate-sharing communication session, the server monitors for coordinate packets from the participating UEs and formats coordinate output frames indicative of selected coordinates at the respective UEs. In another embodiment, the UE receives a coordinate output frame indicative of coordinate selection(s) at the at least one other UE and selectively updates its given visual representation accordingly.
