Abstract: Scenes in video images are identified based on image content of the video images. Regional cross sections of the video images are determined based on the scenes in the video images. Image portions of the video images in the regional cross sections are encoded into multiple video sub-streams at multiple different spatiotemporal resolutions. An overall video stream that includes the multiple video sub-streams is transmitted to a streaming client device.

Abstract: Peripheral-vision expanded images are streamed to a video streaming client. The peripheral-vision expanded images are generated from source images in reference to view directions of the viewer at respective time points. View direction data is collected and received in real time while the viewer is viewing display images derived from the peripheral-vision expanded images. A second peripheral-vision expanded image is generated from a second source image in reference to a second view direction of the viewer at a second time point. The second peripheral-vision expanded image has a focal-vision image portion covering the second view direction of the viewer and a peripheral-vision image portion outside the focal-vision image portion. The second peripheral-vision expanded image is transmitted to the video streaming client.
