1. A non-transitory, processor-readable medium for mitigating IR interference from a display device, the non-transitory, processor-readable medium comprising processor-readable instructions configured to cause one or more processors to:
- initiate a calibration mode;
generate test patterns for display on the display device, the test patterns configured to induce infrared (IR) emissions from the display device;
measure by a television receiver IR emissions during the display of the test patterns;
determine IR emission characteristics;
determine an IR configuration based at least in part based on the IR emission characteristics, the IR configuration comprising settings for IR signaling to mitigate an error rate on received IR signals from an IR remote control caused by the IR emissions, wherein the IR configuration determination further comprises determining for the IR remote control issuing the IR signaling one or more lowest energy requirements at which the error rates on reception are below a threshold;
adding a margin on energy requirement for the IR remote control of at least 10%; and
transmitting the IR configuration to the IR remote control via a backchannel communication path.

Abstract
Various arrangements for monitoring and mitigating infrared (IR) interference from a display device are presented. IR emissions from a display device are measured the IR signaling characteristics may be adjusted to mitigate interference from the emissions. Calibration methods may be used determine display emission characteristics by displaying test patterns and video clips. Characteristics of the display patterns and video clips may be correlated to high IR emissions.

5. A method for mitigating IR interference from a display device, the method comprising:
-
initiating a calibration mode; generating test patterns for display on the display device, the test patterns configured to induce infrared (IR) emissions from the display device; measuring by a television receiver IR emissions during the displaying of the test patterns; determining IR emission characteristics that cause interference with received IR command signals; determining an IR configuration based at least in part based on the IR emission characteristics, the IR configuration comprising settings for IR signaling to mitigate the IR emissions; initiating the IR configuration; scanning incoming programming content currently being displayed with an inactive tuner, wherein the scanning identifies content with image or video characteristics similar to the test patterns that were determined to cause IR emission characteristics that cause interference with received IR command signals; and adjusting the IR configuration to account for the identified content prior to display of the identified content. - View Dependent Claims (6, 7, 8, 9, 10)
