摘要:
Techniques to enable virtual reality content to be delivered using a video codec that operates according to a scalable video encoding standard. Base layer frames for the different views of the virtual reality content are downloaded by a client device. The views are prioritized using a prediction model that assigns priorities based on the likelihood that a corresponding view will be selected within a particular period of time. Enhancement layer frames are then selected and downloaded based on the priorities.
