Moving to the right of the HDMI output is the USB 2.0 port. This allows you to connect a USB flash drive, external hard drive, or iPod with audio, photo, or video files.
Just to the right of the USB 2.0 connection is both a Digital Coaxial and Digital Optical audio connection. Either connection can be used. Check your Home Theater Receiver for the type that you have access to.
Next, there are three more types of video output connections offered. First is the Component Video output. This output consists of Red, Green, and Blue connectors. These connectors plug into the same type of connectors on a TV, Video Projector, or AV receiver. The yellow connection is the Composite, or standard analog video output. Just below the Composite video output is the S-Video output. If you have an HDTV the composite or S-video connections are not required, or advisable, as they cannot pass progressive scan or upscaled video. In addition, although the component video conenctions can output progressive scan video, they can only output upscaled video for non-commercial home-recorded DVDs.
Still moving right, are the multi-channel analog audio output connections. These connections allow access to the internal surround sound decoders of the DV-983H. You have the option of using just two channels, 5.1 channels, or the full 7.1 channel outputs.
Finally, on the far right, are the IR in/out connections and the RS-232 connection. These connections allow more efficient integration of the DV-983H within a custom home theater installation with a central remote control system.
Note: I recommend that if you do not have an HDTV with an HDMI or DVI-HDCP connection, that you consider the purchase a different DVD player than the DV-983H, as you will not be able to access the full potential of this player.
