Zusammenfassung:	Various exemplary embodiments relate to a High-Definition Multimedia Interface (HDMI) switch configured to receive notification of a switch from a current HDMI source to a new HDMI source, determine whether the new HDMI source is actively transmitting data, has attempted to access an HDCI' register before a predetermined timeout delay since a last HDCP register access, and is transmitting unencrypted data, and based on these determinations, either immediately begin transmission of the HDMI data received from the new source or reset the new HDMI source. In this manner, various exemplary embodiments enable switching between HDMI sources with a reduced delay.
