• 1.What is HDMI ?+


    What is HDMI ?

    HDMI (High Definition Multimedia Interface) means a proprietary audio/video interface transmitting from uncompressed video data, compressed to uncompressed digital audio data through a source device conformed to HDMI.  These source devices include display controller, to a conformable computer monitor, video projector, digital TV,  and digital audio device. HDMI acts as a digital replacement for analog TV standards.

  • 2.What is DisplayPort ?+

    What is DisplayPort ?

    Standardized by the VESA (Video Electronics Standards Association), DP (Display Port) is a digital display interface developed by a consortium of PC and chip manufacturers.Initially, the interface connects a video source to a display device (e.g., computer monitor), and can carry audio, USB, and other forms of data.

  • 3.What is SDI ?+



    What is SDI ?

    SDI (Serial digital interface) is a digital video interface category standardized in 1989 by SMPTE (The Society of Motion Picture and Television Engineers). With a formal impedance of 75 ohms, all the various serial digital interface standards use one or more coaxial cables with BNC connectors.

  • 4.What is DVI ?+

    What is DVI ?

    Developed by the DDWG (Digital Display Working Group),  DVI (Digital Display Working Group) connects a video source (e.g., video display controller), to a display device (e.g., computer monitor) with the hope of producing an industry standard for the transmission of digital video content. 

    DVI-I (Integrated; analog and digital). Single link (18+5) or dual link (24+5)

    DVI-D (Digital): Single link (18+1) or dual link (24+1)

    DVI-A (Analog): Analog signal only (12+5)


  • 5.What is VGA ?+

    What is VGA ?

    VGA (Video Graphics Array) is also called D-sub 15 or mini sub D15. VGA transfers analog signal and is worked on graphics card on computers, monitors and other devices. 

  • 6.What is YPbPr / YCbCr ?+


    What is YPbPr / YCbCr ?

    YUV color model is gathered from the rgb model, using luminance and chrominance to represent the color information, making it image processing- competent.    

    YUV (YPbPr/YCbCr) indicates color difference signals. YPbPr is an analog color difference signal while YCbCr is a digital color difference signal. The processing flow is more straightforward:Analog input signal -> A to D convert -> digital signal -> DSP processing -> digital signal (YCbCr) D to A convert -> analog signal (YPbPr)

  • 7.What is RGB ?+


    What is RGB ?

    RGB model is mixing different wavelengths of light to produce other colors. The initials of the three cumulative primary colors, red, green, and blue form the model name.

  • 8.What is EDID ?+


    What is EDID ?

    Metaformat to display devices to draw their abilities to a video source. Data format is outlined by measurement published by the VESA.EDID data structure contains manufacturer name and serial number, product type, phosphor or filter type (chromaticity data), timings provided by the display, luminance data, pixel mapping data (only for digital displays), and display size.

  • 9.What is HDCP ?+


    What is HDCP ?

    Intel Corporation developed HDCP (High-bandwith Digital Content Protection): a form of digital copy protection, preventing copy of digital audio and video content while travelling across connections.

    Types of connections contain DisplayPort, DVI, HDMI, and less popular/deprecated protocols including GVIF (Gigabit Video Interface) and UDI (Unified Display Interface).The system is designed to stop HDCP-encrypted content from playing on impermissible devices that have been altered to copy HDCP content. A transmitting device examines that the receiver is authorized to receive data before sending data. If so, the transmitter encrypts the data preventing the overhearing while it flows to the receiver.
