Arduino to emulate a 315/433Mhz wireless remote control receiver's output.

I looking for precedence on this one, I haven't found in this forum.

I have a product that uses a common 315Mhz remote control receiver as shown (using 4-button remote and many other wireless devices), and I'd like to emulate the wireless receiver's data output with an Arduino nano, etc. to control the unit.

Meanwhile, I'm going to set up one of the receivers with a UNO or nano to display the output from my remote (also shown) to test. Initially I just want to capture the data from the 4 button remote. These are the type of units im using.
