What do the abbreviations "MXP" and "FXP" stand for?

What do the abbreviations "MXP" and "FXP" stand for? I understand they are a representation of the quality of recording in terms of data per single frame. But cannot find anywhere what the abbreviations stand for... Thanks.

MXP is 24Mbps, FXP is 17Mbps

BTW, higher bitrate means not as lossy, and generally better quality

Thank you very much! Do you happen to also know what the letters themselves stand for? - Val

I don't think the actual letters have a specific word attached or as a abreviation.  They ae just letters.

Memory capacity	MXP (app. 24Mbps)	FXP (app. 17Mbps)	XP+ (app. 12Mbps)	SP (app. 7Mbps)	LP (app. 5Mbps)
64GB	5 hours 55 min.	8 hours 20 min.	11 hours 30 min.	19 hours 10 min.	24 hours 30 min.

I think in the beginning LP stood for Long Play but I don't know for sure.
