The specification allows for USB Type-C cables to be made with no need for extra dongles or converters and allow compatible devices to output video directly from a USB-C device to a TV display. This means that smartphones tablets laptops cameras and any other devices with a USB-C port can be built to directly output video to any TV display with a single cable.

Alt Mode which stands for Alternative Mode allows non-USB signals to be carried through a USB-C cable. Other USB-C Alt Modes support DisplayPort MHL and Thunderbolt. USB-C devices that support these Alt Modes can then with the correct USB-C cable transfer those signals in addition to regular USB data.
