Which interface provides the fastest transfer data rate when capturing high-definition video?

• A. HDMI
• B. USB 2.0
• C. Component video
• D. FireWire

Answer: (A)

High-bandwidth digital transmission wins for HD capture. HDMI is designed to carry uncompressed video (and audio) over a single cable with very high bandwidth, which means it can transfer the large HD data stream in real time without needing compression. USB 2.0 tops out around 480 Mbps, which is far too slow for uncompressed HD video and often forces compression or reduces quality. Component video is an analog interface, so it doesn’t transmit digital data and is more susceptible to noise and degradation, plus it lacks integrated audio. FireWire can handle digital video and offers higher speeds than USB 2.0, but its typical maximum is still below HDMI’s modern bandwidth. For capturing HD efficiently, HDMI provides the fastest data transfer.
