Abstract
A method is provided to efficiently transport video signals on a wireless network when resources are scarce. In an embodiment, a user's mobile terminal codes the video in multiple layers. If resources are scarce, the mobile terminal reduces current bandwidth requirements by streaming a subset, i.e., one or more of the lower coded video layers only. This streamed video can be viewed by peers and saved on a server. Meanwhile, the higher layers that were not sent are saved on the mobile device. When network resources eventually become available, the saved higher layers only are sent to the destination server that saved the lower layers. The entire video can then be reconstructed on the destination server.
