Interface module for transmitting digital video signal
First Claim
1. An interface module for transmitting a digital video signal comprising:
- a transmitting interface unit having (1) a first 4-core optical fiber cable, (2) a first 4-core male optical connector provided at one end thereof, and (3) a first digital visual interface (DVI) connector provided at another end thereof, said first DVI connector including a light emitting device unit converting RGB signals and clock signals from electrical to optical signals and a built-in display data channel (DDC) signal generating means for outputting identification information associated with a video output display unit and being attached to a first DVI connector terminal of a host device outputting a video signal;
a receiving interface unit having (1) a second 4-core optical fiber cable, (2) a second 4-core male optical connector provided at one end thereof, and (3) a second DVI connector provided at another end thereof, said second DVI connector including a photo detector unit converting RGB signals and clock signals from optical to electrical signals and being attached to a second DVI connector terminal of a video output display unit; and
a 4-core optical cable unit consisting of (1) a third 4-core optical cable and (2) 4-core female optical connectors provided at both ends thereof, the 4-core female optical connectors designed to be engaged with the first and second 4-core male optical connectors,wherein each of the lengths of the first and second 4-core optical fiber cable is greater than or equal to one fourth of the circumference of a circle whose radius corresponds to an allowable bend radius of the first and second 4-core optical fiber cable.

Abstract
An interface module for transmitting a digital video signal includes: a transmitting interface unit which is designed to be connected to a host device for outputting a video signal, and which has a cable connection consisting of a 4-core optical fiber cable and a 4-core male connector provided at one end thereof; a receiving interface unit having a cable connection designed to be connected to a video output display unit and consisting of a 4-core optical fiber cable and a 4-core male connector provided at one end thereof; and an optical cable unit for transmitting TMDS signals consisting of RGB signals and clock signals. The transmitting and receiving interface units are interconnected by the optical cable unit. The transmitting interface unit includes a second integrated circuit outputting identification information (DDC signal) associated with the video output display unit.
