Measurement of IR emissions and adjustment of output signal
First Claim
Patent Images
1. A television receiver 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;
initiate a calibration mode;
cause a series of images of video content to be displayed on a display device, the series of images to induce infrared (IR) emissions from the display device;
process a measurement of IR emissions during display of the series of images;
determine IR emission characteristics of the measurement of IR emissions;
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; and
initiate the IR configuration to account for incoming programming content to be displayed on the display device with images and/or video characteristics corresponding to the series of images that were determined to cause the IR emission characteristics that cause interference with received IR command signals.

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.
