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

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
