    Abstract: A system and machine-implemented method are described for communicating with a plurality of distributed-input-distributed-output (DIDO) clients. For example, a method according to one embodiment comprises: determining channel state information (CSI) defining a channel state between each of a first plurality of DIDO antennas and each of the DIDO clients; using the CSI to determine distributed-input-distributed-output (DIDO) precoding weights for each of the channels between each of the first plurality of DIDO antennas and the antennas of each of the DIDO clients; using the CSI and DIDO precoding weights to determine link quality metrics defining link quality between each of the first plurality of DIDO antennas and the antennas of each of the DIDO clients; using the link-quality metrics, to determine modulation coding schemes (MCSs) for different DIDO clients; and transmitting precoded data streams from each of the first plurality of DIDO antennas to each of the individual DIDO clients using the determined MCSs for those clients.

    Abstract: A system and method are described for performing motion capture on a subject using transparent makeup, paint, dye or ink that is visible to certain cameras, but invisible to other cameras. For example, a system according to one embodiment of the invention comprises the application of makeup, paint, dye or ink on a subject in a random pattern that contains a phosphor that is transparent in the visible light spectrum, but is emissive in a non-visible spectrum such as the infrared (IR) or ultraviolet (UV) spectrum; using visible light such as ambient light or daylight to illuminate the subject; using a first plurality of cameras sensitive in the visible light spectrum to capture the normal coloration of the subject; and using a second plurality of cameras sensitive in a non-visible spectrum to capture the random pattern.

    Abstract: A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: detecting a maximum data rate of a communication channel between a server and a client; dynamically selecting a tile size for encoding a sequence of images based on the detected maximum data rate; logically subdividing each of the sequence of images into a plurality of tiles sized according to the selected tile size, each of the tiles having a defined position within each of the sequence of images; encoding each tile within each image of the sequence of images using a first compression format or a second compression format, wherein a tile at a particular position of a first image in the sequence of images is encoded using the first compression format and the same tile within one or more subsequent images is encoded using the second compression format.
