A.V. Systems Video Distribution And I.R. Integration
External Sources • Cable T.V. and Satellite signals are considered External Sources • These are wide spectrum, broadband • External signals should be distributed via structured cabling using a distribution panel • High quality amplifiers should be used • Splitters should be avoided
Internal Sources • Video generated within the home or building is called “Internal” • Examples are VCR, DVD or demodulated satellite signals as well as closed circuit video camera signals • These should be modulated and mixed with the external signals for distribution
A.V. Systems Infrared Control Universal Remote Programming Systems Integration
Characteristics of I.R. • Infra Red is light that is invisible to the naked eye because it is beyond the normal wavelength that we can see • It is generated by an I.R. L.E.D. • It is detected by I.R. receiver • Serial digital signals are modulated onto the L.E.D. and demodulated after the detector
I.R. Signals • The signal is serial data. • I.R. works on line of sight. • I.R. cannot go through objects • I.R. can reflect as normal light
Distribution • It is sometimes useful to have I.R. transferred between rooms • It is sometimes useful to have I.R. generated in or behind a cabinet and control a device not in “line of sight” • It is sometimes useful to have I.R. control equipment in a cabinet not visible to the handheld remote control
Universal Remote Control and Systems Integration • Pre-Programmed • Learning • Usually only for A.V. Equipment • X-10 R.F. provides “system integration” • I.R. to X-10 converter can be used • X-10 to I.R. can provide programmed I.R. integration
Advanced Remotes • Touch Screen + Hard Buttons • Touch Screen programmable
Complete Control Systems • The high-end • Complete systems integration including theatre, lighting, security.
