Configurable A/V Jack Signal Direction

This idea is basically to include an option in the TV (or other AV applicance)'s menu. You can set each set of jacks to the direction you need.

For example: If you need to plug in three DVD Players, you can simply set three sets of jacks (assuming the equipment has them) as inputs to receive the signals. If you needed audio/video out, set one set of jacks as an output.

Additional options could include the ability to set the TYPE of signal being accepted. (Composite vs. Component vs. digital audio, etc. - Requires compatible connector on back of set. Those three above use the same connector type and cable...)
