How to Convert Digital Optical to AV

There are several types of digital video (or optical) cables, such as DVI (Digital Visual Interface) and HDMI (High-Definition Media Interface), that are used to transport video signals between devices such as televisions and computers. Although the cables may send audio signals also, many only carry digital video. If you are sending the digital optical signal to an analogue device, you need to convert the digital content to an analogue audio/video (AV) connection.This requires you to connect a digital to analogue cable converter. Thankfully you can find one of these devices at most electronic stores.

  1. 1

    Plug the digital cable into the digital out port on the television, computer, or other device you are using the connection with.

  2. 2

    Insert the opposite end into the "Digital In" port on the converter. You need to make sure you have a converter that matches the cable you are using. If using a DVI cable the converter must be used for "DVI" cables, or if using an HDMI cable the convert must have an "HDMI" port.

  3. 3

    Plug the analogue RCA audio/video cables into the "Video Out" ports on the converter. Make sure the colours of the cables match the same colours on the convert.

  4. 4

    Insert the opposite end of the cables into the "In" port on the device you want to send the digital optical signal to.
