  • Publication number: 20180227579
    Abstract: A method and system for view optimization of a 360 degrees video is provided. The method includes generating two-dimensional video frame from the 360 degrees video. The macroblocks are generated for the two-dimensional video frame. A foveated region of interest for the two-dimensional video frame is defined based on a given view orientation. DCT (Discrete Cosine Transform) coefficients are generated for the macroblocks. View adaptive DCT domain filtering is then performed on the DCT coefficients using the foveated region of interest. Quantization offset is calculated for the DCT coefficients using the foveated region of interest. The DCT coefficients are quantized using the quantization offset to generate encoded two-dimensional video frame for the view orientation. A new view orientation is then set as the given view orientation and steps of generating, performing, calculating, and quantizing are performed for each view orientation and each video frame to generate view optimized video.

  • Patent number: 9908048
    Abstract: Systems and methods for executing a game presented on a screen of a head mounted display include executing a game. The execution of the game renders interactive scenes of the game on the screen of the HMD. Images identifying a shift in gaze direction of the user wearing the HMD, are received. The gaze shift is detected during viewing of the interactive scenes presented on the HMD screen. Real-world images that are in line with the gaze direction of the user, are captured from a forward-facing camera of the HMD. A portion of the screen is transitioned from a non-transparent mode to a semi-transparent mode in response to the shift in the gaze direction such that at least part of the real world images are presented in the portion of the screen rendering the interactive scenes of the game. The transparent mode is discontinued after a period of time.
