  • Systems and methods to enhance spatial diversity in distributed-input distributed output-wireless systems
    Publication number: 20120314649
    Abstract: Systems and methods are described for enhancing the channel spatial diversity in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”), by exploiting channel selectivity indicators. The proposed methods are: i) antenna selection; ii) user selection; iii) transmit power balancing. All three methods, or any combination of those, are shown to provide significant performance gains in DIDO systems in practical propagation scenarios.

  • Apparatus and method for performing motion capture using shutter synchronization
    Patent number: 7605861
    Abstract: A method is described comprising: applying phosphorescent paint to specified regions of a performer's face and/or body; strobing a light source on and off, the light source charging the phosphorescent paint when on; and strobing the shutters of a first plurality of cameras synchronously with the strobing of the light source to capture images of the phosphorescent paint, wherein the shutters are open when the light source is off and the shutters are closed when the light source is open.

  • Method for multicasting views of real-time streaming interactive video
    Publication number: 20090119729
    Abstract: A method includes multicasting by a server center of streaming interactive video/audio streams to multiple destinations via an outbound Internet traffic interface. A given video/audio stream is routed to multiple destinations simultaneously. At least one of the video/audio streams is received at a delay buffer of the server center, the delay buffer storing a replayable portion of at least one of the video/audio streams.
