  • Publication number: 20150326352
    Abstract: A method and apparatus for increasing the data rate and providing antenna diversity using multiple transmit antennas utilize a set of bits of a digital signal to generate a codeword. Delay elements may be provided in antenna output channels, or, with suitable code construction, delay may be omitted. n signals represent n symbols of a codeword are transmitted with n different transmit antennas. At the receiver, the noisy received sequence is decoded. The parallel transmission and channel coding enables an increase the data rate over previous techniques, and recovery even under fading conditions. The channel coding may be concatenated with error correction codes under appropriate conditions.

  • Patent number: 9154975
    Abstract: A system and method supporting access to multimedia information based upon user-defined quality of service criteria is disclosed. A broadband access gateway may coordinate network behavior during the transition of an access device among communication pathways having different available capacities. Adjustments in bit rates and levels of compression may be made based upon the user-defined quality of service criteria.

  • Publication number: 20150264341
    Abstract: A communication system is described that allows co-located viewers to simultaneously consume different media content, such as different video content, via the same display screen, wherein video content delivered to at least one co-located viewer is not visible to the other co-located viewer(s). The communication system comprises an infrastructure that includes multiple pathways for delivering media content from one or more media sources to the eyes of each of the co-located viewers, wherein each pathway passes through the pixels of a pixel array included in the shared display screen. The pathways also include distributed or non-distributed processing circuitry that manages certain resources that are shared among the multiple pathways, wherein such shared resources may include shared display resources (e.g., pixels of the pixel array and light generated thereby) and shared data communication resources (e.g., bandwidth on data communication links and processing resources of nodes located on such links).

  • Publication number: 20150256141
    Abstract: A monoscopic camera comprising one or more image sensors and a depth sensor may generate video based on two-dimensional image data captured via the one or more image sensors and corresponding depth information captured via the depth sensor. The camera may process corresponding audio for the generated video based on the captured depth information. The audio processing may comprise mitigating noise in the corresponding audio, enhancing voice quality in the corresponding audio, and/or enhancing audio quality of the corresponding audio. The camera may be operable to determine, based on the captured depth information, one or more sound paths between a source of the corresponding audio and a microphone utilized to capture the corresponding audio emanating from the source. The processing of the audio may comprise removing portions of the captured audio arriving at the microphone via one or more reflection paths.

  • Patent number: 9118375
    Abstract: Block-encoded transmissions of a multi-antenna terminal unit are effectively detected in the presence of co-channel interfering transmissions when the base station has a plurality of antennas, and interference cancellation is combined with maximum likelihood decoding. More specifically, the signals received at the base station antennas are combined in a linear combination that relates to the channel coefficients between the various transmitting terminal units and the base antennas. By selecting proper coefficients for the linear combination and choosing probable transmitted signals that minimize a minimum mean squared error function, the signals of the various terminal units are canceled when detecting the signal of a particular unit. In another embodiment of the invention, the basic approach is used to obtain an initial estimate of the signals transmitted by one terminal unit, and the contribution of those signals is removed from the received signals prior to detecting the signals of other terminal units.

  • Patent number: 9100640
    Abstract: A monoscopic video camera may capture, via at least one image sensor, two-dimensional video, and may capture, via at least one depth sensor, corresponding depth information for the captured two-dimensional video. The monoscopic video camera may then configure color related processing of video information corresponding to objects in the captured 2D video based on the captured corresponding depth information. Configuring color processing may comprise setting and/or adjusting color information associated with the objects. In this regard, setting and/or adjusting color information may be based on shadow, shade, and/or edge related information associated with the objects, which may be generated and/or modified based on the captured corresponding depth information based on the captured corresponding depth information. Configuring color processing may be based on surrounding regions adjacent to the objects.

  • Publication number: 20150215858
    Abstract: A method and device support the use of background network scanning to enable association with a first and at least a second wireless network, for the exchange of exchange of multimedia information. Representative embodiments of the present invention may sniff radio frequency spectrum and determine at least one characteristic of detected wireless networks having capacity for exchange of the multimedia information. More than one wireless network may be identified for use in exchanging the multimedia information, which may be communicated concurrently over the identified wireless networks. User defined criteria may be employed in adjusting communication of the multimedia information to meet a quality of service level desired by a user. A lack of wireless network capacity may result in adjustments to, for example, protocols used to represent multimedia information, frame rate, and spatial or color resolution, in order to maintain or enable communication.
