Abstract
Methods and apparatus for panoramic multimedia streaming where viewers may control spatial coverage of panoramic video components of multimedia signals are disclosed. A novel flexible streaming server is devised to perform client-specific content filtering in addition to adapting multimedia signals to characteristics of individual client devices as well as to varying capacities of network paths to client devices. The server may distribute software modules to client devices to enable viewers to communicate preferred view regions of a panoramic scene. The server includes a learning module devised to retain viewing-preference data, correlate viewing preference to characteristics of client devices, and determine a default viewing preference for each client device. The server implements computationally efficient schemes of generating and distributing content-filtered multimedia signals to clients. The server may be implemented using hardware processing units and memory devices allocated within a shared cloud-computing network.
