I am sceptical that the MP has been derived from the video arena. Rather, as one of the reviews points out, the RUR process is derived from something the audio recording industry already uses. But that is only one third of the story. Then you also have to consider that the Error Correction Codes for video are much more sophisticated and are not compatible with the Reed Solomon ECC used for the Compact Disc.
Furthermore, the MP uses a flash memory for storing the data that is to be played back. Put RUR, dropping RS-ECC, and playback from flash memory all together, and the MP moves into the unique category. At least from what I have been able to construe.
