    y As demand arises, content providers are using various content protectiontechnologies to prevent unauthorized uses.

    y High-bandwidth Digital Content Protection (HDCP) protects the last stage inthe distribution process, encrypting content transmitted over digital interfaces

    from set-top boxes, DVD players, personal computers and game consoles, todisplay devices such as high definition TVs.

    y Required HDCP for HDMI

    y In this session we discuss about:-

    1.) How it protects content??????

    2.) HDCP License Agreement.

    3.) Authorized test centers.

    if the material being played

    is an unprotected

    Dont encrypt non-HDCP content from non-HDCP sources

    Make sure HDCP recovers after your repeater switches from one source

    to another (with a different timing) and back.

    Make certain that your repeater detects and forwards all hot-plugs to

    up-stream devices, even if the hot-plug signals only last for 100

    milliseconds.

    y Quantum Data has joined forces with other industry leaders to solve the give

    guidelines problem..

    y Last year, DCP released a supplement and compliance test standard. HDCPcompliance currently relies on self-policing.

    y DCP has established a test lab where HDCP licensees can come and testinteroperability with a suite of real products.

    y Quantum Data is following through with a two-pronged solution that includesgrafting HDCP debug and compliance test features onto existing video testinstruments - to help design engineers stem the flow of new non-compliant designsentering the market - and creating new tools to help installers isolate problems with

    legacy products already in the field.

    y Researchers have used theQuantum Data and Panasonic tools to survey a large cross-section of existing products. Their findings helped establish the list of design bestpractices discussed in this article. Researchers also have found and correctedweaknesses in the test equipment and the HDCP compliance test standard

    y Manufacturers who choose to use HDCP need to

    license it from DCP. By doing so, they agree to

    comply with the HDCP License Agreement and

    accordingly, make their products compliant with the

    HDCP specification and compliance rules and

    relevant interfaces such as HDMI,
