I'm working on a project involving DAT machines (which are wonderful)
that requires control of the machines by a computer (for broadcast
automation). The only control external to the machine is an IR handheld
control. I need to emulate the signal that unit creates and interface
it to my project. 

I opened the unit and found an NEC controller IC and called NEC who
sent me the data sheets. I was disapointed to find that it was a
microcontroller with on-board screened ROM full of sony code to make it
run.  

I have to beleive that there are dumb chips out there that could do
the same thing, or perhaps some alternative. It would be useful to
control many "consumer" products that use infra-red remotes.     

I'm having difficulty finding where to get started. If any of you know
of any app-notes or primers on this type of thing, please let me know.
