Im very familiar with Adobe Transmit. It means you can use just regular Adobe sequences (CUDA and all) and get HD SDI play out thru AJA, BM or Matrox hardware into an engineering monitor or tape machine. Adobe provided a hook for third party vendors to their video stream thus allowing a simpler and more stabile way to send video out to their hardware. It suffers from none of the issues users had with previous version of CS Premiere. Final drivers still pending, but then again CS6 hasnt been released yet. :D
