The I2C protocol allows communications across a "bus" between a master device, multiple masters, and one-or-more slave devices. Two wires are required, supporting communication with up to 112 devices, with one line carrying a clock signal and the other line carrying data. The video shows using I2C on Arduino using the GY-80 board and GY-521 board, both of which has several sensors. The video shows how to communicate with those devices using Arduino Sketch programs.
