Being that - Tradução em português

Hello friends, I couldn't understand exactly this sentence, the use of "being that " seems a little confuse to me!

Being that they didn't vote as the public believed they would, a relatively obscure film walked away with the event's top honor!

I imagine it can be the same as: ( Já que... )

But I know this structure " já que " as " since "

I really do not know whether I'm right or not, but you can help me and i'm sure of it!!!

Thanks in advance!!!!!
