Video gets captured uncompressed, meaning its bits and pieces are let out of their cage -- out of the algorithm that packed them tight onto the camera's memory card -- and are shuttled through to a computer without any further loss, whereas without capacity for uncompressed transfer, not many alternatives can substitute sufficiently.
The transfer from the camera to the Shuttle is done through an HDMI cable, and from the Shuttle to the computer can also be by HDMI, but available on the Shuttle is a Thunderbolt port, which is an advanced data-transfer technology that with a 10Gbps capacity is extremely fast. Thunderbolt is also bidirectional and can thus serve as an input and an output. The receiving computer -- or storage device -- must also be equipped with Thunderbolt. Macs were the first of any devices to be equipped, and all Macs are equipped.
Data does not stay in the Shuttle before moving on to the computer. The Shuttle serves as a pass-through only; and at the data's passing through, resolution can be adjusted to arrive in the computer higher or lower. SD can become HD and vice-versa, so that if you have footage from different cameras shot in different resolutions, you can match them up to look the same.
The Shuttle is a capture-and-playback device, more often referred to as an I/O device for its inputs and outputs. Aside from the HDMI and Thunderbolt connections already mentioned, the Shuttle also has analog video ins and outs, as well as HDMI and RCA audio ins and outs.
The Shuttle is portable, allows many conveniences in transferring footage, affords quality transfers, and delivers video to computers in codecs most recognized by popular editing systems.
