I need a chip that can input analog video and have a flag, that shows there is a external video input or not from input analog video terminal. I have known tvp5150 can provide FID or vsync locked in different register model by one pin , but I want to get the two signals by different pins at one time. My question is which chip can provide the two signals at one time? At the same time, I hope the chip has a small size. Thank you!

    The TVP5150AM1 INTREQ could be used to provide a locked state interrupt on pin 27.  See I2C registers COh and C1h.
