Combining the advantages of the centralized P2P structure and the data-driven structure with scalable video coding, we propose an adaptive P2P architecture for live video based on scalable wavelet video coding over internet. The core operations are simple: every peer periodically exchanges data availability and bandwidth information with the central server, acting as the centralized index, which selects and sends a set of partners that have expected data to the demanding node. And the central server classifies one peer to a certain level according to the peer’s downloading bandwidth which coordinates with the layer level of the video data encoded using scalable wavelet coding. The peer retrieves correspondingly unavailable data from partners according to availability information.
