  • System and method for operating an electronic device having an HDMI port that is shared between HDMI source function and an HDMI sink function of the electronic device
    Patent number: 8966306
    Abstract: A system and method for operating an electronic device having a High-Definition Multimedia Interface port that is shared between an HDMI source function and an HDMI sink function of the electronic device utilizes detecting whether an external HDMI device that is attached to the HDMI port is one of an HDMI source and an HDMI sink. If the external HDMI device is detected as being an HDMI source, the HDMI sink function of the electronic device is enabled. If the external HDMI device is detected as being an HDMI sink, the HDMI source function of the electronic device is enabled.

  • Fast HDMI switching with conditional reset mechanism
    Patent number: 8375150
    Abstract: Various exemplary embodiments relate to a High-Definition Multimedia Interface (HDMI) switch configured to receive notification of a switch from a current HDMI source to a new HDMI source, determine whether the new HDMI source is actively transmitting data, has attempted to access an HDCP register before a predetermined timeout delay since a last HDCP register access, and is transmitting unencrypted data, and based on these determinations, either immediately begin transmission of the HDMI data received from the new source or reset the new HDMI source. In this manner, various exemplary embodiments enable switching between HDMI sources with a reduced delay.

  • Method and circuit for extracting synchronization signals in a video signal
    Patent number: 7705917
    Abstract: The invention relates a method of extracting synchronization signals from an input video signal (Csync) comprising horizontal synchronization pulses at the start of video lines, for generating a horizontal synchronization signal (Hsync), said method comprising:—a calculation step (105) for calculating the duration (D) of the video lines in said input video signal (Csync),—a forcing step (108) for forcing said input video signal (Csync) to an output level, said output level corresponding to the level of said input video signal (Csync) after the horizontal synchronization pulses, said input signal (Csync) being forced between the end of each horizontal synchronization pulse and a moment defined by a first percentage (X1) of said line duration (D), for generating said horizontal synchronization signal (Hsync). Use: Extraction of synchronization signals.
