Abstract: The disclosed embodiments relate to a system and method for modifying video signals. The system may comprise at least one decoder that decodes a video signal that comprises embedded picture setting data, and a video processor that is adapted to detect whether the system is operating in an on-screen display (“OSD”) mode, apply the embedded picture setting data if the system is not in the OSD mode, and withhold the embedded picture setting data if the system is in the OSD mode. The method may comprise the acts of decoding a video signal that comprises embedded picture setting data, detecting whether a system is operating in the OSD mode, applying the embedded picture setting data if the system is not in the OSD mode, and withholding the embedded picture setting data if the system is in the OSD mode.

Abstract: An apparatus and method for controlling a video signal processing apparatus having a browser feature to protect a display device associated with the apparatus against the premature aging effects of screen burn due to an idle display when the browser feature is activated. The method includes the steps of detecting a first user input to a video apparatus, determining whether the first user input activates a browser feature of the video apparatus, and controlling the operation of the apparatus to reduce the screen burn. The operation can include setting a display parameter for the video apparatus to a first predetermined level responsive to determining that the first user input activates the browser feature, or determining an idle time and inactivating the browser feature if the idle time exceeds a predetermined period of time.

Abstract: An electronic system including a connector for an external device such as an infrared receiver includes a signal processor, responsive to the infrared receiver and an electrical isolation device such as an optocoupler, coupled between the connector and the signal processor. Such a system can further include electromagnetic interference suppression circuitry such as a ferrite bead, capacitors coupled to the earth potential, coupled between the connector and the optocoupler. Such a system can also further include electrostatic discharge suppression circuitry resistors coupled between the connector and the optocoupler.
