I want to use the camera and mic on my iPad to "call" a TV hooked up to Apple TV to deliver a live message to my kids viewing in the basement. How to?

For example: kids are watching videos on ATV in the basement. I want to use my iPad upstairs to send camera video and mic audio to the tv (all networked together of course) to let them know to come up for dinner. Any suggestions - either with standard iPad apps or third party apps?
