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:

• receiving, at the second codec, a videoconferencing signal transmitted by the first codec to the second codec through the videoconferencing connection between the first codec and the second codec;
• analyzing, by the second controller, the videoconferencing signal received at the second codec to determine a calibration adjustment value by comparing at least one signal level value of the videoconferencing signal to a calibration target according to at least one calibration adjustment rule;
• and
• transmitting the determined calibration adjustment value to the first controller to allow the first controller to adjust a signal level setting of the first codec according to the determined calibration adjustment value.

A controller for calibrating a videoconferencing system, the system including a first codec connected to a second codec through a videoconferencing connection, the controller comprising:

• an input in communication with the first codec for obtaining a videoconferencing signal received by the first codec from the second codec through the videoconferencing connection;
• and
• an output for transmitting a calibration adjustment value to another controller over a network, the other controller in communication with the second codec;
• wherein the controller is configured to analyze the obtained videoconferencing signal received by the first codec to determine the calibration adjustment value by comparing at least one signal level value of the videoconferencing signal to a calibration target according to at least one calibration adjustment rule, and to transmit the determined calibration adjustment value to the other controller to allow the other controller to adjust a signal level setting of the second codec using a level adjustment command of the second codec, the level adjustment command corresponding to the determined calibration adjustment value.
