Most new HDTVs do not have an RF input, so if like me you like to use your old retro hardware such as a SNES, Commodore 64 or ZX Spectrum without any modifications on a modern big screen TV you will need a way of converting the RF output of the hardware to a HDMI compatable input.
Most conversion devices available with work in the opposite way to which you need. These devices will take a HDMI input and convert it to an RF signal so you can use new equipement such as PVRS and Amazon fire sticks an use them on an older TV. These devices are NOT what you need. I can be confusing for some what they need and may end up wasting money on the wrong device.
This article is designed to help you find the correct converter and save you the time and money getting the wrong device or cable.
The device that you need is know as an RF Demodulator. This will demodulate the signal back into an analogue video signal then digitise the signal into a format compatable with DVI and HDMI.
Here are some Products that will do the Job.
