Abstract:
Innovations in stream configuration operations and playback operations for adaptive streaming of panoramic video are described. The innovations include features of adaptive streaming of panoramic video with overlapping sections. For example, a stream configuration tool splits an input picture of panoramic video into overlapping sections. A playback tool reconstructs one or more of the sections. Because of overlap between adjacent sections, for gradual changes in a view window, the playback tool can, in effect, preemptively fetch a new section as the view window moves out of a current section into the new section. By the time the view window reaches a non-overlapping part of the adjacent, new section, the playback tool has retrieved encoded data for the new section and can reconstruct the new section. This hides network latency and stream switching latency from the viewer, and disruption of playback is avoided.

Claim (Index 12):
A computer system comprising one or more processing units and memory, wherein the computer system implements a panoramic video playback tool that includes:\n a view controller configured to:\n determine a view window for playback of panoramic video; \n from among multiple sections of the panoramic video, identify one or more sections that contain at least part of the view window, each of the multiple sections overlapping at least one other section among the multiple sections, thereby reducing incidence of disruption attributable to bitstream switching; and \n for the one or more identified sections, select one or more bitstreams among multiple bitstreams for corresponding video streams; \n a streaming controller configured to request encoded data, in the one or more selected bitstreams for the one or more identified sections, respectively, for an input picture of the panoramic video; one or more input buffers configured to store the encoded data; one or more video decoders configured to decode the encoded data to reconstruct the one or more identified sections for the input picture; a mapper configured to, based at least in part on the one or more reconstructed sections, create an output picture; and an output buffer configured to store the output picture for output to a display device.
