UC IR-Code Format

Hello
For Pronto formated IR codes there exists a definition like here:
Pronto Format specs

So the RC-5 Code “1D08” in Pronto is:
0000 0073 0000 000A 001C 0026 003E 0046 001C 0026 001C 0026 003E 0046 003E 0026 001C 0046 003E 0026 001C 0026 001C 0026

The RC-5 Code “1D08” learned by Dock3 gives back:
1;0xF48;12;0
But where can I find a description of this special UC Hex format?
