On video products intended for consumner TV, AC coupled or DC coupled outputs?

[FusionITR]

I have a general question reguarding generic AV products for consumer TV use. Is the industry standard for video outputs to be ac coupled and for the reciever to handle dc restore (if needed by the rx) the signal? Or is it industry standard to provide a DC bias to the video signal? I would figure that consumner TVs would expect an AC coupled singal by I just wanted to be sure.

It's usually AC coupled, DC restoration is done in the receiving device.
