Dragonborn and Dragon Blood are the same. Just because the Dragonborn Emperors didn't shout doesn't mean they couldn't. The only reaason we as Dovahkiin can shout is because of the absorption of a dragon soul, which the Septim's couldn't get because there were no dragons for them to claim the souls of. And to everyone saying they've researched this, I know this simply from paying attention to people talking in Skyrim (And Paarthurnax).
