3.6.1. HDCP Status Signals
There are several signals that are useful to identify the working condition of the HDCP IP cores. These signals are available at the design example top-level and are tied to the onboard LEDs:
Signal Name | Function |
rx_hdcp1_enabled | RX HDCP1x IP Decryption Status 0: Inactive 1: Active |
rx_hdcp2_enabled | RX HDCP2x IP Decryption Status 0: Inactive 1: Active |
tx_hdcp1_enabled | TX HDCP1x IP Encryption Status 0: Inactive 1: Active |
tx_hdcp2_enabled | TX HDCP2x IP Encryption Status 0: Inactive 1: Active |
Refer to Table 34 for their respective LED placements.
The active state of these signals indicates that the HDCP IP is authenticated and receiving/sending encrypted video stream. For each direction, only HDCP1x or HDCP2x encryption/decryption status signals is active. For example, if either rx_hdcp1_enabled or rx_hdcp2_enabled is active, the HDCP on the RX side is enabled and decrypting the encrypted video stream from the upstream video source.
