Videoconferencing calibration systems, controllers and methods for calibrating a videoconferencing system

A method of calibrating a videoconferencing system, the videoconferencing system comprising a first controller in communication with a first codec, and a second controller in communication with a second codec, the second codec connected to the first codec though a videoconferencing connection, the method comprising:

• transmitting, by the first codec, a videoconferencing signal to the second codec through the videoconferencing connection between the first codec and the second codec;
• receiving, by the first controller, a calibration adjustment value from the second controller;
• and
• adjusting, by the first controller, a signal level setting of the first codec using a level adjustment command of the first codec, the level adjustment command determined according to the calibration adjustment value transmitted by the second controller.

A videoconferencing calibration system comprising:

• a first videoconferencing component;
• a first codec in communication with the first videoconferencing component;
• a second codec connected to the first codec via a videoconferencing connection;
• a first controller in communication with the first videoconferencing component and the first codec, the first controller configured to control the first videoconferencing component to transmit a videoconferencing signal to the second codec though the videoconferencing connection;
• and
• an output component coupled between the first codec and the first controller, the first controller configured to control the first videoconferencing component to transmit a local videoconferencing signal to the output component though the first codec, analyze the local videoconferencing signal received at the output component to determine a local calibration adjustment value, and adjust a local level setting of the first codec according to the determined local calibration adjustment value.
