Efficient streaming of virtual reality content

A processor device for processing Virtual Reality (VR) content, the processor device comprising:

• memory configured to store data;
• one or more processor in communication with the memory and configured to:
• receive tracking information including at least one of user position information and eye gaze point information:
• predict, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed;
• render a portion of the next frame of video data to be displayed at an estimated location in the next frame using the prediction;
• determine, based on the estimated location of the portion in the next frame, a corresponding matching portion in a previously encoded frame;
• and
• encode the portion of the next frame of video data.

A tangible, non-transitory computer readable medium comprising instructions for causing a computer to process Virtual Reality (VR) content, the instructions comprising:

• receiving tracking information including at least one of user position information and eye gaze point information;
• predicting, based on the user tracking information, a user viewpoint of a next frame of a sequence of frames of video data to be displayed;
• rendering a portion of the next frame of video data to be displayed at an estimated location in the next frame using the prediction;
• determining, based on the estimated location of the portion in the next frame, a corresponding matching portion in a previously encoded frame;
• and
• encoding the portion of the next frame of video data
