Introduction to aCVi

aCVi is SingMai's proprietary (and trademarked) method for the long distance transmission of high definition video.

aCVi can transmit high definition video across more than 300m of coaxial or twisted pair cable with near broadcast quality, and longer distances with some small signal degradation.
