SAP HANA Enterprise vs SAP HANA Live difference

I know that SAP HANA Live is used for real time reporting but I can't see the difference between SAP HANA Live and SAP HANA Enterprise? Isn't Enterprise optimized for real time reporting too? Is SAP HANA Live a small package of SAP HANA Enterprise containing only those tools which support real time reporting? Or these technologies are the same only the marketing name is different?

Thanks
