Hdcp 2.2 License Agreement

To create a device that broadcasts HDCP content, the manufacturer must obtain a patent license from intel`s subsidiary Digital Content Protection LLC, pay an annual fee and submit to different conditions. [5] [6] [7] The device cannot be developed to copy z.B. It must “destroy attempts to overcome the requirements of content protection”; [7] no high-resolution protected video should be transmitted to non-HDCP receivers; and DVD audio works can only be played in audio CD quality[7] from non-HDCP digital audio outputs (analog audio outputs have no quality limits). The following licenses are available. Please note that the following PDF documents are non-executable documents. You`re only for REVIEW. Provides a license for the use of HDCP Specification 2.x Review technologies. No additional fees are required. Each HDCP device has a unique set of 40 56-bit keys. If they are not kept secret, it goes against the licensing agreement. For each set of values, a specific private key called KSV (Key Selection Vector) is created.

Each KSV consists of 40 bits (one bit for each HDCP key), with 20 bits out of 0 and 20 bits out of 1. As we discussed in a previous blog post, the HDMI specification is not an open standard; You must be licensed by HDMI LLC to be able to implement HDMI in any product or component. COMPANIEs with HDMI LLC licenses are called HDMI adopters. The HDMI license is mandatory if you intend to use your logo to promote/market/market your final product as an HDMI compliance device. Remember that there is no easy licensing fee, the product must also pass a number of HDMI compliance tests. If HDMI doesn`t apply to your device, you don`t need to be a user. Before developing HDMI interfaces, it is important to understand the steps necessary to ensure that your device is properly licensed. The HDCP license is required to purchase HDMI components with HDCP keys. Depending on the HDCP specification associated with the component, you may need to become both HDCP1.x and HDCP2.x-Adopter. Without the license, you can`t buy a component with HDCP encryption, decryption or both.

All HDCP-enabled devices are licensed by Digital Content Protection. This license ensures that manufacturers take appropriate measures to protect transferred content or risk losing their license. Only trusted devices are allowed. If a device violates the terms of the license agreement, its KSV can be added to a retraction list, so future transmitters refuse to send it to the revoked device. On September 14, 2010, Engadget announced the release of a possible HDCP master key, capable of creating device keys that can authenticate with other HDCP-enabled devices, without obtaining the valid key to The Digital Content Protection LLC.
