In accordance with the link below, we must enter into an HDCP-Adopters license agreement if we use HDCP. The full adoption agreement that offers a license for the manufacture of HDCP 1.x components and products as well as for the purchase of hdcp 1.x kits. Each HDCP-enabled device has a unique set of 40-56-bit keys. Failure to keep it secret is contrary to the license agreement. A specific private key called KSV (Key Selection Vector) is created for each value set. Each KSV consists of 40 bits (one bit for each HDCP key), with 20 bits set to 0 and 20 bits to 1. . HDCP strippers remove HDCP information from the video signal so that data can flow freely on a non-HDCP display. At present, it is unclear whether such devices would continue to function if the HDCP licensing body created blacklists of available keys via new media (e.g.B. Newer Blu-ray discs) can be installed, reproduced by another connected device (for example.
B a blu-ray disc player). . 2- No DHCP license is required for the tramitter side. . There is also the problem that all Apple laptop products, presumably to reduce switching time when faced with an HDCP-enabled sink device, automatically enable HDCP encryption via the HDMI/Mini DisplayPort/USB-C port. This is a problem if the user wants to use recording or video conferencing devices further down the chain, as these are the devices that most often do not decrypt HDCP-enabled content (given that HDCP is supposed to avoid copying content directly and such devices could do so). The same applies when the output is not HDCP-oriented content, for example. B a PowerPoint presentation or only the user interface of the device.  Some sink devices may disable their HDCP coverage altogether, which prevents this issue from blocking video conferencing or video recording content. However, HDCP content is not reproduced on many source devices when this is disabled, while the sink device is connected.  Did you return the thread ez.analog.com/docs/DOC-15751 The authors concluded that the linear exchange of hdcp keys is a fundamental weakness and discussed the tracks: Why work with Symmetry Electronics?
