Optical Transmission System Using Relay Adaptor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical transmission systems require long optical cables when two video cameras are used for shooting, as the base station is typically positioned far from the mobile production control room, leading to inefficient cable length and increased complexity.
Innovation Solution
An optical transmission system where the second camera adaptor acts as a data transfer point, allowing one optical transmission cable to connect the base station to the second camera adaptor and another to connect the second adaptor to the first camera adaptor, reducing the total cable length by configuring the system to utilize shorter distances between adaptors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the base station is positioned far from the shooting place (about 1 km) and two video cameras are used, then the coverage area and transmission distance are improved, but the total length of optical transmission cables required increases to 2 km (two 1-km cables)
Solution Approach 1:
The invention introduces an intermediate camera adaptor that serves as a relay station. The first camera adaptor converts the electric signal from the first video camera into an optical signal and transmits it to the second camera adaptor. The second camera adaptor then transmits this optical signal to the base station. This intermediary approach allows the system to achieve long-distance transmission (1 km coverage) while reducing the total cable length required, as the cable is routed through the intermediate adaptor positioned at the shooting location rather than requiring two separate 1-km cables from the base station to each camera.
2Reliability
If two separate optical transmission cables of 1-km length are prepared for each video camera, then reliable signal transmission is ensured, but the cable management complexity and physical space requirements increase
Solution Approach 1:
The invention merges the transmission paths by routing both camera signals through a common intermediate point (the second camera adaptor). Instead of having two separate 1-km cable runs from the base station to each camera, the system combines the paths so that the optical signal from the first camera is transmitted through the second adaptor to the base station. This merging reduces cable management complexity and physical space requirements while maintaining signal transmission reliability through the optical transmission medium.
3Adaptability or versatility
If the base station is positioned 800 m from the first camera adaptor and 500 m from the second camera adaptor, then the operational flexibility and camera placement options are improved, but the conventional cable routing would require excessive cable length
Solution Approach 1:
The invention uses the second camera adaptor as an intermediary relay point that enables flexible camera placement. The first camera adaptor transmits the optical signal to the second adaptor, which is positioned 500 m from the base station. The second adaptor then relays the signal to the base station. This intermediary configuration allows the first camera to be positioned 800 m from the base station while only requiring a 300 m cable segment between adaptors plus a 500 m cable segment to the base station, totaling 800 m of cable rather than the conventional approach which would require much longer cable runs.

AI summary
According to the present invention, in an optical transmission system optically transmitting an optical signal between a first camera adaptor provided to a first video camera, a second camera adaptor provided to a second video camera, and a base station provided at a position remote from the video cameras, the first camera adaptor converts a first electric signal including a video signal component from the first video camera into a first optical signal and transmits the first optical signal to the second camera adaptor. The second camera adaptor receives the first optical signal, converts a second electric signal including a video signal from the second video camera into a second optical signal, and transmits the first and second optical signals to the base station. The base station receives the first and second optical signals, converts the received optical signals into the first and second electric signals, and outputs the electric signals to an external device.
