Hello. I have some questions about component video connection. I have heard many types of connections refered to as component video but I have noticed many different configurations I guess you could say. Here are a few I know of. Y Pb Pr Y Ry By Y Cb Cr (also called YUV) RGB I know RGB is different than the rest and not interchangable (although I don't know why) but how about the others. For example. I am looking at getting a line scaler that has a Y Cb Cr input and a Y Pb Pr output. I think my DVD player has the Y Pr Pb output. Are they compatiable? Another line scaler I was looking at has Y Ry By inputs and outputs. Tech support said they are compatible with Y Pr Pb but she didn't sound too sure of her answer. Are they compatatable? Is one progressive scan and the other interlaced. Please help. Thanks. Also, I appoligize if this is in the wrong forum.
