1. A television receiver configured to mitigate IR interference from a display device, the television receiver comprising:
- one or more processors;
a non-transitory memory communicatively coupled with and readable by the one or more processors and having stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to;
monitor for error rates on received IR signals from an IR remote control; and
when the monitored error rates are determined to satisfy a threshold, automatically initiate a calibration mode comprising;
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 sensor at the television receiver, IR emissions during the display of the test patterns;
determine IR emission characteristics;
determine an effect of the IR emission characteristics on one or more commands received from the IR remote;
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 interference from the IR emissions;
initiate the IR configuration;
scan incoming programming content with an inactive tuner, wherein the scanning identifies content with image or video characteristics similar to the test patterns that were determined to cause interference with received IR command signals; and
adjust the IR configuration to account for the identified content prior to display of the identified content.

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.

11. 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 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 (12, 13, 14, 15, 16)
