Abstract

Point to multi-point wireless video delivery. Among a group of receiver wireless communication devices (RXs), one is designated (e.g., as acknowledgment (ACK) leader). Media delivery operational parameters are selected based on the designated RX or based on all or a subset of the RXs. For simultaneous media delivery to multiple RXs, characteristics associated with the designated RX [or all, or a subset or RXs] govern the manner by which communications are made. Different respective RXs may be designated to serve in this role at different times. Wireless delivery of media (e.g., video signaling, audio signaling, etc.) to a group of RXs is effectuated in accordance with modified multicast signaling with a designated leader (e.g., ACK leader). Among a group of devices, a least successful receiving device that still receives media at an acceptable level may be chosen as the designated leader (e.g., ACK leader).
