Enhanced signaling of regions of interest in container files and video bitstreams

摘要

Systems and methods are provided for specifying regional information, such as priority and priority viewport among multiple recommended viewports, and source and nature. The virtual reality video data can represent a 360 degree view of the virtual environment. In various examples, an area of virtual reality video data is determined, where the area includes a subsection of a 360 degree view. A data structure can be created for the region, where the data structure includes parameters that describe the region. The parameters can include the source associated with the region. Virtual reality video data and data structures may be stored in a file.
