Abstract: In one embodiment, images of a first user in a video conference are captured with one or more physical video cameras. The captured images are processed to form a three-dimensional (3-D) model of the first user. A location on a display screen is determined where an image of each of one or more second users in the video conference is shown. One or more virtual cameras are positioned in 3-D space. Each virtual camera is associated with a respective second user and positioned in 3-D space based on the location on the display screen where the image of the associated second user is shown. A view of the first user from the perspective of each of the one or more virtual cameras is rendered. The rendered view of the first user from the perspective of each virtual camera is shared with the associated second user for the respective virtual camera.

Abstract: A presentation system includes a remote device with a dynamic storage subsystem that dynamically updates designated storage locations in actual or virtual memory with content for presentation at times associated with the presentation of the updated content by a presentation device. The presentation device, which is connected to the remote device by a data transport connection, accesses the content from the designated storage locations and presents the content as playback data.

Abstract: A computer system includes USB class protocol-aware modules for USB devices as part of a xHCI host controller. The protocol-aware modules serve as accelerators by implementing critical portions of the device class protocols, which includes fetching higher level protocol data directly from client buffers for transmission and delivering decoded data to client buffers on receipt; and emulating a register-based interface for the benefit of system software on the host computer.
