I have questions about difference of HDCP version between ADV7511 and ADV7511W.
ADV7511 datasheet says "Compatible with HDCP 1.4."
Also, ADV7511W datasheet says "Compatible with HDCP v1.3."
Why is the HDCP version different between ADV7511 and ADV7511W?
Why does the ADV7511W only support up to HDCP 1.3?
