My suggestion:

This will give you a list of active input devices
 $ ls  /sys/class/rc/rc*/input*/name
 /sys/class/rc/rc0/input14/name

This will tell you the 'name' attribute for each
 $ cat  /sys/class/rc/rc*/input*/name
 DViCO FusionHDTV DVB-T Dual Digital 4

Then you should be able to write something like this
 $ cat /etc/udev/rules.d/10-persistent-ir.rules
 KERNEL=="event*",ATTRS{name}=="DViCO FusionHDTV DVB-T Dual Digital 4",SYMLINK="input/dvico-remote"

which will create /dev/input/dvico-remote

To test, first find the event number associated with the input

 $ ls -F /sys/class/rc/rc0/input14/
 capabilities/  device@  event9/  id/  modalias  name  phys  power/
 properties  subsystem@  uevent  uniq

 $ sudo udevadm test /class/input/event9
 <buried in the output you should see something like:
   creating link '/dev/input/dvico-remote' to '/dev/input/event9' >
 $ echo $?
 0

Kind regards
