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.
