By the other reviews I was more insecure, so I hesitate to buy this part. The adapter works absolutely unproblematic. On one side is the HDMI port, on the other are the 3 RCA analog connections (audio left and right as well as video). The adapter provides the connection between my laptop with an HDMI connector and TV / VCR with Video / Scart connections with me. While a USB cable is supplied for power connection, but for me the adapter receives power via the HDMI port, Remarkably, the converted signal is even better than the original on the laptop monitor, so I now can watch BBC itself in standard quality in very acceptable picture quality over the Internet Filmon service.
