Is there any way to seamless switch between sources on the ADV7850 or to do it quicker? We seem to average around 3-5 seconds.
It really depends on what's getting switched. Here's some of the factors that efffect switching time
1) sink re-locking to new format, usually takes a few frames for the sink to re-lock and show good video
2) If HDCP is active then switching will require HDCP authentification and take a bit of time. For best speeds you need to keep fast switching activated keeping the various HDMI authenticated. This is dependent on how the software sets up the parts and handles the various events. Check out the manual, section 7.15 on fast switching.
How are you testing this? on one of our eval boards or custom hardware?
