Thunderbolt is the latest protocol for peripherals used by Apple on its computers to carry audio, video, data and power over a single cable. The protocol combines Apple’s DisplayPort technology and PCIe into a single connectivity path. The technology can be used to daisy-chain numerous devices, including storage, monitors and broadcast I/O hardware. Thunderbolt ports are currently available on Apple MacBook Air, MacBook Pro, Mac mini and iMac computers. Manufacturers such as AJA Video Systems, Blackmagic Design and Matrox have embraced Thunderbolt technology and have engineered a number of capture and output devices for it.
