The client is requesting that I include closed-captioning for broadcast with CEA-608-B selected. The only option in Episode that's even close to that is EIA-608. I did a little research to find out what the CEA and EIA are, but is there a difference in these formats? I also need to provide CEA-708 NADBS, and the only thing close to that on Episode is "EIA-608 + EIA-708". What is what here? Thank you.
