It's a fully software-based VHS decoder. It takes the raw signal from a VHS tape, captured with a high speed sampling device, and reconstructs the video on your computer. In theory, this approach should allow higher quality digitization than any physical VHS player - it cuts the analog decoding electronics out of the loop, and it allows you to capture once, then tweak the algorithm and decode many times without disturbing the tape. You could even preserve the raw captures in case better decoding algorithms come out in the future.
