Abstract
A panoramic multimedia streaming server communicatively coupled to numerous client devices of different types enables individual client devices to dynamically select view-regions of interest. A source video signal capturing a panoramic field of view is processed to generate a pure video signal faithfully representing the panoramic field of view. The pure video signal is content filtered to produce multiple view-region-specific video signals corresponding to predefined view regions within the panoramic field of view. Frame samples of the pure video signal are transmitted to a client device to enable selection of a view region of interest. Upon receiving, from the client device, an indication of a view region of interest, a controller selects a specific predefined view region according to proximity of each predefined view region to the indicated view region of interest. A view-region-specific video signal corresponding to the specific predefined view region is streamed to the client device.
