Depending on the quality and specifications of the audiovisual source, HDCP encryption of digital audio may be required. When HDCP is active, packetized data island transport audio is also encrypted along with the video data per HDCP v1.4. I2S audio transmitted in forward channel frame transport mode is not encrypted. System designers should consult the specific HDCP specifications to determine if encryption of digital audio is required by the specific application audiovisual source.
