That signal is NECx1 Device 12.12, with function numbers:
A few UEI remotes send this IR Protocol on setup code Cable/Sat 0539, and the following brands are listed as using this setup code:
Astra, Aura, Eurostar, M&B, Micro Technology, Seg, Skymax, and Starion.
0539 has a different mapping of button label to function number. Vol+ would be sent by the digit 0 button, Vol- by 4, Power by 7, Source is not available, and Mute by 2.
