The present invention relates to a multimedia cable.

The present invention relates to a multimedia cable. 2. Description of the Related Art Various display devices including a monitor, a TV, a projector, and the like are connected to various types of external input devices and can receive and output video signals and sound signals.

In particular, since a TV or the like is equipped with an audio output device by itself, in order to connect an external input device to a TV and enjoy video and sound, a TV and an external input device are connected to a video signal transmission cable and a sound signal transmission cable I had to connect and use it.

Most of the flat panel display devices are constituted by a digitizing method. In the past, various types of interfaces (ports or cables) used for connecting external input devices have been widely used. It was not easy to know which cable should be plugged in to which port if you wanted to connect the computer's peripherals.
