1. A remote control unit for a television system, comprising:
- a light sensor configured to sense light from an image displayed by a remote television;
a microphone; and
logic configured to measure a sound characteristic of the television system based on the light sensed by the light sensor and sound sensed by the microphone, the logic further configured to transmit a wireless signal based on a measurement of the sound characteristic by the logic.

Abstract
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.
