<p>A circuit, method and system for determining which type of video signal is to be generated by a media player are described herein. In the described embodiment, the media player has three video ports for transferring different types of video signal with each type of video signal requiring a predetermined number of ports for transferring its video signals, for example s-video requires two video ports. To determine which type of signal to generate, the detection circuit comprises a detector arranged to detect which of the video ports have a load coupled thereto, and is further arranged to control the media player to generate the type of video signal according to the number of ports detected that is coupled with the load.</p> |
