SYSTEMS AND METHODS FOR USING A REMOTE CONTROL UNIT TO SENSE TELEVISION CHARACTERISTICS

摘要

A system for sensing television characteristics comprises a display device, a speaker, a calibration manager, and a remote control unit, which has a light sensor, a microphone, a transmitter, and logic. The logic is configured to determine, based on the light sensor and the microphone, a value indicative of an amount of time that elapses between emission of sound from the speaker and a detection of the sound by the microphone. The transmitter is configured to transmit a wireless signal based on the value, and the calibration manager is configured to adjust a parameter of a television system based on the wireless signal.
