It might depend on what region the converters are made for as to what the IRE level is. I would imagine the chinese made ones would 0IRE but who knows. Same thing for all the Cypress and rebranded converters from Taiwan. Thats one thing you just dont really know if its set up for NTSC or PAL. Are americal companies such as AVtool, Hall research, Ambery etc getting the same converters as the CYP versions sold in many PAL regions except for different colour casing and power supplies or are those american companies getting Cypress to tweak the black level to suit american market????? so many questions.
I want to get one like thishttp://www.ebay.com/itm/Hall-Researc...item3373e52e83
Just not sure on what brand yet. When i get one i will let you know what its like.
By the way Cypress just emailed me so i took the opportunity to ask them if there are any differences between their componernt converter and the ones they manufacture for the USA companies such as AVtool, Atlona, Hall research etc. I asked if they change the black levels or anything.
I would suspect not because the devices are sold as being NTSC and PAL compatible
