Patent number: 8774229Abstract: A wireless broadcast system that collects content for distribution over a wireless communication network. The content stream is encapsulated into a stream of transport packets for broadcast over the wireless communication link. The stream of transport packets are simultaneously broadcast as part of an identical signal from a plurality of synchronized transmitters in a single frequency network. A receiver acquires the broadcast signal and synchronizes to the signal. Once the receiver is synchronized to one of the transmitters in the single frequency network, the receiver can receive signals from any, or multiple, of the transmitters in the network without re-synchronizing.Type: GrantFiled: January 12, 2007Date of Patent: July 8, 2014Assignee: WI-LAN, Inc.Inventors: Dennis P.
