4k60Fps hdmi processing suggestions

I need to process incoming 4k hdmi stream at 60Fps and search for particular symbols in the video stream and alert the user accordingly. Can anyone suggest if any of the nvidea development boards in conjunction with some external hardware is there for this purpose…


Do you mean you want to catch the incoming HDMI stream and check if some symbol if over it? or you want to process a frame to find a symbol before it is sent to display?

These two are totally different.
