Intel® NUC systems can be used with Media Center Edition infrared remote controls (and others), like the ones listed in the article below. I am not aware if it will work with your TV’s remote but hopefully other users will comment about their experiences.
As far as I know, the IR commands are saved/mapped in Windows* registry, which can be changed with third party software, such as the ones you mentioned or others.

I advise caution when modifying Windows* registry and/or using third party software.
Unfortunately, the built-in CIR infrared receiver (NUC 5th gen.) does not "understand" the signals - codes - from the Panasonic TV remote control, mentioned above.
I installed WinLIRC and EventGhost with Windows 7 Pro 64 on the NUC. These Software applications do not interprete any infrared signal, which is transmitted from the TV remote control to the NUC. Thus, I am pretty sure that it is a General issue refarding the CIR Nuvoton Receiver. That's the reason, why I deinstalled (deleted completely) Win 8.1 Pro 64 and installed Win 7.
Meanhwhile, I ordered a Pluse Eight HDMI CEC (USB) Adapter to control the Intel NUC with the TV remote control 'indirectly', means via the Viera Link provided by the Panasonic TV.
