ABSTRACT:
A method transports a video over a network that includes multiple paths. First, a video is encoded into a base layer, one or more low bit-rate enhancement layers, and one or more high bit-rate enhancement layers using fine-granularity scalability. The base layer and the low bit-rate layers are duplicated into a multiple base layers and multiple low bit-rate enhancement layers, respectively. The high bit-rate layers are partitioned into multiple partial low-bit rate layers, and then each layer is transmitted over a different path of the network to a receiver.
