does LA72910V (or any other) chip modulates composite signal ?

[plouf]

hello i am looking for a chip, or simple schematic, tha can take composite color signal as input, modulate it at any frequency
and then some other or same chip that demodulates it back in composite

googling a lot , found LA72910V (https://www.onsemi.com/PowerSolutions/product.do?id=LA72910V) but cannot understand if is that and most important if it can do it in color


does anyone understand that ?
and/or if anyone knows any other chip to do this

thanx

Since the carrier frequency is around 11.5MHz, this IC may handle black and white composite video signals even any bandwidth has not been mentioned.
I think it's used only to send the black and white video signals over a transmission medium such as local electric lines via a transformer.Just a guess..

thanx for the reply

do you know any other chip that modulates composite signal to any frequency and demodulates it back ?
