Looking for clarification on BE 2012 SP2

I hope this isn't too basic a question...

In the article "Backup Exec 2012 revision 1798 Service Pack 2" is the "1798" the version of the Service Pack or the version of Backup Exec to which the Service Pack is applied?

We have run LilveUpdate, and it says that there are no updates available, so I presume that we are at the latest version.

"About Backup Exec 2012" shows:

Backup Exec Serv er: Version 14.0 Rev. 1798 (64-bit)

Thanks!
