Connect two s-video cables or convert an s-video male port/connector to a female port/connector. Extend the distance of your s-video cable by coupling the two cables together. This flexibility helps you place your DVD player, digital camcorder, satellite system or any s-video component away from your TV monitor. The connector's molded design reduces EMI/RFI interference. Each end of the coupler is 4-pin mini din female; the standard 4-pin for s-video.
