SDI (Serial Digital Interface) (With BNC connectors and coaxial cables)
S-Video (Super-video)
Component Video
CAT 5 / ethernet (eg video baluns)
USB
Firewire
Wireless systems of transmission?
Research Questions?
– What signals does this cable carry?
– What is the signal quality / strength? (How do we measure this?)
– What is the maximum recommended distance for this cable?
– How easy is it to extend the range of?
- How easy is it to split / duplicate the signal?
– Average Cost? (In Melbourne 2012, per metre?)
– Are there any compatibility issues?
– Advantages / Disadvantages?
– Any other potential issues?
