I’m looking to make an infrared protocol converter box for my DVR. Any input will do but I need to output XMP-R 62.16 (protocol used for many of the Comcast DTAs and STBs). I’m trying to find some information about the XMP-R (XMP1) protocol but I haven’t seen anything in my searches. Does anyone know if this goes by a different name? I’ve seen the remote codes provided in hex format for use with various IR blasters, but I don’t understand, without seeing the protocol, carrier frequency, and pulse lengths how to translate these values into a signal. If anyone knows where I could find some information on this IR protocol to get me started that would be very helpful. I’ve been searching for a couple of days but haven’t turned up anything conclusive yet.
