It's probably RCA (the red, yellow, and white cords?) judging by the look of it, and considering it's from Fisher Price. I highly doubt they're shipping these things to go through a Blu-Ray player or anything like that. You should be fine with your projection TV. I don't think I've seen more than two TVs without RCA jacks in my life. They started putting them on there before I was born and haven't stopped since. It's a standard.
