Abstract
An interface system for a television receiver includes an interface connector having a plurality contacts connected to various component circuits in the television receiver. In order to provide various functions for the television receiver, the interface system includes various circuit boards each having a plug connectable with the interface connector. The plug includes a number of contacts equal to or less than the plurality of contacts in the interface connector. Depending on the desired function, the circuit board further includes circuits for providing the function, these circuits being interconnected and connected to the appropriate contacts in the plug for connecting with the appropriate component circuits in the television receiver. The interface system allows the television receiver functions to be modified and/or updated without the need for opening the television and modifying the circuits and/or the wiring to the circuits.
