Audio Video Converter is used to convert analog (stereo) and video (composite or S-Video) HDMI digital signal. Ideal in situations where the device has only one output analog AV or S-VIDEO (such as VCR, old models of camera, etc.) And you want to connect to the monitor (projector, TV) with no analog inputs (certain models have only digital inputs HDMI or DVI). IDATE SPDIF-5, as well as RCA and S-Video, also supports HDMI input. This way allows the display of wonderful videos on your HDTV.
