Document Type and Number:
WIPO Patent Application WO/2019/037706
Kind Code:
A1
Abstract:
The disclosure relates to technology for providing determined future fields of view (FoVs) of a 360 degree video stream in a network having multiple video streams corresponding to multiple FoVs. FoV interest messages including requests for FoVs at time instants of the video stream are collected from viewers of the stream. A sequence of popular FoVs is created according to the messages, each representing a frequently requested FoV at a distinctive time instant. FoV transitions are created according to the FoV interest messages, each FoV transition including a current FoV a time instant and a next FoV of a next time instant, indicating a likely next FoV to be subsequent requested. Future FoVs of future time instants are determined for a user viewing the video stream with a history of requested FoVs of past time instants, based on the history of requested FoVs, the sequence and the transitions.
