ABSTRACT:
A method for distributing a digital motion picture to multiple theaters in a region via terrestrial wireless communication. The motion picture is divided into chunks, and the chunks are transmitted to particular initial seed theaters in the region. To facilitate the initial seeding, downlink bandwidth on various wireless links is dynamically increased. Once the initial seeding is complete, the downlink bandwidth is decreased and is preferably equalized substantially with uplink bandwidth. The theaters in the region are then directed to begin peer-to-peer sharing of the chunks with each other, possibly through use of BitTorrent or other cooperative downloading process from the initial seed theaters. Ultimately, all of the theaters in the region thereby obtain all of the chunks of the motion picture and can conveniently present the motion picture to audiences.
