Publication number: 20230073542Abstract: 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 composite pictures. For example, a stream configuration tool splits an input picture of panoramic video into multiple sections and creates multiple composite pictures. A composite picture includes one of the sections as well as a low-resolution version of the input picture. A playback tool reconstructs one or more composite pictures. Under normal operation, the playback tool can use the reconstructed section(s) of the composite picture(s) to render high-quality views of the panoramic video. If the view window dramatically changes, however, or if encoded data for a section is lost or corrupted, the playback tool can use the low-resolution version of the input picture to render lower-quality details for views of the panoramic video, without disruption of playback.Type: ApplicationFiled: September 8, 2022Publication date: March 9, 2023Inventors: Matthew WOZNIAK, Bakkama Srinath REDDY, Amr MARTINI

Patent number: 10666863Abstract: 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.Type: GrantFiled: May 25, 2018Date of Patent: May 26, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Matthew Wozniak, Bakkama Srinath Reddy, Amr Martini
