  • Publication number: 20160127771
    Abstract: In some aspects, the disclosure is directed to methods and systems for transporting multimedia data, such as ultra-high definition (UHD) video data or other video data, via a standard high-definition multimedia interface (HDMI), without requiring an increase in the link bit rate or increasing the number of signaling pairs. Display stream compression is utilized to compress a stream, and a transition minimized differential signal (TMDS) clock channel may be replaced by an ANSI 8b/10b encoded stream carrying additional data with a clock signal embedded within the stream. As this additional channel increases bandwidth by one-third, the systems and methods discussed herein provide four times more effective bandwidth than prior HDMI schemes, allowing UHD video to be transmitted via a signal HDMI link.

    Abstract: Provided are systems and methods for providing enhanced motion detection. One system providing enhanced motion detection includes a smart display, an interface subsystem including a human interface device (HID), and a console having a processor configured to form communication links with the smart display and the interface subsystem and to provide motion detection feedback, using the smart display, to a user of the HID, where the HID is configured to sense motion of the HID and utilize a predictive model to characterize the motion of the HID. One interface subsystem includes a camera to sense motion of a user of the HID. One processor is configured to negotiate a reduced response latency with the smart display.

  • Patent number: 8942259
    Abstract: One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multichannel audio, video, control, timing, closed captioning or other digital data.

  • Publication number: 20080089456
    Abstract: A dual link receiver terminates, recovers, channel aligns, and link aligns a plurality of primary link channels and a plurality of secondary link channels. The plurality of primary link channels and the plurality of secondary link channels are each received, bit recovered, synchronized, decoded, and channel aligned. Then, the plurality of primary link channels and secondary link channels are link aligned. Link alignment operations first determine a relative misalignment between the plurality of primary link channels and the plurality of secondary link channels. A primary link delay is then applied to the primary link channels and a secondary link delay is then applied to the secondary link channels. A difference between the primary link delay and the secondary link delay is based upon the misalignment between the plurality of primary link channels and the plurality of secondary link channels. An enabling circuit precludes an incorrect blanking period indication.

  • Publication number: 20070002965
    Abstract: A dual link transmitter constructed according to the present invention employs a single Phase Locked Loop (PLL) to service both a primary link and a secondary link during dual link mode operations. The structure of the dual link transmitter includes both a primary link PLL and a secondary link PLL. The primary link PLL produces a primary link clock and the secondary link PLL produces a secondary link clock. During dual single link operations, the primary link clock is used to service the primary link while the secondary link clock is used to service the secondary link. However, during dual link operations, the primary link clock is used to service both the primary link and the secondary link.

  • Publication number: 20020163598
    Abstract: The present invention relates to a method of transporting video and audio data. The method includes receiving, by a first transmitter (CE transmitter, for example), a video data stream and an audio data stream. The first transmitter generates a composite data stream from the audio data stream and the video data stream. The first transmitter communicates the composite data stream to a second transmitter (DVI 1.0 transmitter, for example), which in turn transmits the composite data stream to a remote receiver.

  • Publication number: 20020097869
    Abstract: The present invention relates to a system and method for increasing the digital data capacity of a digital video link without increasing the pixel clock rate. The invention uses a shorter blanking period than the standard blanking period, in order to send more data over each channel of the digital video link. By shortening the vertical and horizontal blanking periods, the amount of time in each scan line available for sending data is increased. The inactive video portion of a scan line sent during vertical sync is also used to send auxiliary digital data, which could be additional channels of digital audio or other digital data.
