Wireless streaming of interactive multi-view video via network compression and path diversity

We formulate a system framework for network compression of interactive multi-view streaming video. The setup comprises a media server that delivers the content over two independent network paths to a client. Our system features a proxy-server located at the junction of the wired and wireless portions of each path. The proxy dynamically adapts the content data sent over the wireless links, in response to channel quality feedback from the client, such that video distortion at the client is minimized. We analyze the performance of our system and contrast its characteristics with dynamic content adaptation at the source and conventional streaming architectures, including scalable video. We numerically simulate the operation of all streaming systems under comparison and establish a close agreement between our analysis and the experimental findings. The proposed system delivers superior video quality over the reference competitors, while enabling notable transmission rate savings, at the same time.
