While it has been reported that the Thunderbolt 3 controller (DSL6540 and DSL6340) features an integrated LSPCON to convert one of the DP 1.2 signals provided to the controller into an HDMI 2.0 signal with HDCP 2.2, I was wondering whether the controller also adds HDCP 2.2 copy protection to either the Thunderbolt 3 port (via USB Type-C), the native DP 1.2 port (via USB Type-C), and/or the native DP 1.2 port (via standard DP or mDP) that can be provided by the controller?
As a followup question, having reviewed Volume 1 of the 6th Generation Intel Core Processor Family datasheet, looking on page 44 under note 7 for Table 2-19: "HDMI2.0 implemented via LSPCON device. Only one LSPCON with HDCP2.2 support is supported per processor platform." Does this limitation only affect additional LSPCON for DP 1.2 to HDMI 2.0 w/ HDCP 2.2 conversion, or does it also affect any controller/integrator which may add HDCP 2.2 copy protection? For instance, could a motherboard manufacturer utilize the MegaChips MDCP2800 LSPCON to convert one of the processor's DP 1.2 signals into HDMI 2.0 w/ HDCP 2.2 and also use the Thunderbolt 3 controller to provide HDCP 2.2 support over Thunderbolt 3 and/or native DP 1.2 (assuming such HDCP 2.2 integration is possible for these ports using the Thunderbolt 3 controller, if not, via some other HDCP 2.2 integrator) and allow the user to access all 3 displays (1 HDMI 2.0 one, 2 Thunderbolt 3/DP 1.2 ones) at once with HDCP 2.2 protected content?
The reason I ask this question is because according to this slide provided by Lattice Semiconductor, it seems that Thunderbolt 3 controllers do provide support for HDCP 2.2 over the Thunderbolt ports as well. I would like to confirm this with Intel staff however.
