  • Publication number: 20110157257
    Abstract: Display systems are described that include an adaptable parallax barrier that filters light passed by a display panel in a manner that allows for the simultaneous viewing of two-dimensional images, three-dimensional images and multi-view three-dimensional content in different display regions. The display system also includes a backlight panel comprising an array of light sources that may be individually controlled to vary the backlighting luminosity provided to the display panel on a region-by-region basis. Since each of the display regions may be perceived as having a different number of pixels per unit area depending upon the type of content being presented, the backlight array enables the brightness of each region to be controlled such that a viewer perceives roughly uniform brightness across all regions. Alternative regional brightness control schemes are also described.

  • Publication number: 20110157327
    Abstract: Techniques are described herein for supporting 3D audio delivery accompanying 3D display supported by viewer/listener position and orientation tracking. For example, audio content is configured to have a spatial orientation that accords with an orientation of a viewer. A spatial orientation of audio content is a configuration of the audio content in which characteristics of respective portions of the audio content, which correspond to respective speakers, indicate an orientation of ears of a viewer/listener with respect to sound source(s) that correspond to (e.g., are depicted in) a three-dimensional view. Such a characteristic may include an amplitude of sound that corresponds to a sound source and/or a delay associated with the sound that corresponds to the sound source.

  • Publication number: 20110158137
    Abstract: Systems and methods are used to adjust, e.g., reduce, current driving a transmitter, i.e., to reduce transmitter power consumption, based on an actual value of a received signal from received along a cable. For example, this is very beneficial to an Ethernet system where the received signal is attenuated by the lossy cable. In this case, the transmitter power consumption can be lowered during a normal application where data is transmitted and received through the cable.

    Abstract: A multi-speed burst mode serializer/de-serializer (SerDes) is configurable and can operate in one of a plurality of operating modes. The plurality of operating modes correspond to the reception of signals from optical network units that operate at different nominal speeds. These various modes of operation can enable a single SerDes design to apply to a variety of speeds and network configurations (e.g., point-to-point or point-to-multipoint). In one example, the design can be initially configured for operation with a single ONT or a network of ONTs at a single speed, or can be dynamically configured during operation for use with a network of ONTs operating at different speeds.
