What is GVIF?

GVIF (Gigabit Video InterFace) is a video interface developed by Sony in 1996 for high quality uncompressed video transmission from digital video hardware.

The biggest advantage of this video interface was that it did not need any specific multicore cables or signal super converters but required only cable with twisted pair, transmitter and receiver chips. Video signal could be transmitted over twisted pair at a distance up to 20 meters. Data was transmitted in real time at a high rate with no image quality loss.

In comparison with features of other interfaces available at that time GVIF was a real break-through.
