Abstract:
Transmitting video with portable devices (such as smartphone), over heterogeneous networks with satellite portions, to a Remote Monitoring Host (RMH) represents a hot scientific and technical topic. Unfortunately, heterogeneity often implies impairments such as packet losses, due to errors and congestion, which negatively affect the video quality. To guarantee a satisfactory video fruition at the RMH, an application layer joint coding algorithm for video transmission is presented. It adaptively applies both video compression and encoding to protect the sent video stream, at the application layer, on the basis of the overall network condition estimated in terms of both maximum allowable throughput of the network and quality (packet cancellations or lossiness). A preliminarily performance study, carried out with real implementation of the algorithm, compares the joint coding against fixed schemes.
