Arduino controlled video switch



I wan to build a video switcher with 2 channels, something that has 2 video input (left/right channels) and 1 video output. And control it with Arduino.


The input channels will be 2 dvd player and the output will be a videoprojector.


I don't use normal mechanical relays because of I am afraid of some glitch when I switch the channel, this is the most important thing: the switch must be fluid, no light interruption, no glitch, no flickering.


I've seen in the internet those 2 possibility: NJM2244 and DG542DJ-E3. But I don't know which fits more my needs.


Do they requires some extra regulation? Are the right IC I need?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
