Comprehensive AV Systems for Video Distribution and IR Integration

This guide covers the essentials of audio-visual systems, focusing on video distribution and infrared (IR) integration. External sources like cable TV and satellite signals must be effectively managed and amplified through structured cabling and distribution panels. For internal sources, modulating signals from devices like VCRs and DVD players is crucial. It also discusses the characteristics of IR technology, including its dependency on line-of-sight and potential for wireless distribution. Advanced remote controls facilitate seamless integration across AV systems, lighting, and security.

Presentation Transcript

  1. A.V. Systems Video Distribution And I.R. Integration

  2. 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

  3. 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

  4. A.V. Systems Infrared Control Universal Remote Programming Systems Integration

  5. 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

  6. 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

  7. 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

  8. Wireless I.R. distribution

  9. Wireless I.R. distribution

  10. In Cabinet Solution

  11. Wired I.R. Distribution

  12. Wired I.R. Distribution

  13. Wired I.R. Distribution

  14. Wired I.R. Distribution

  15. 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

  16. Advanced Remotes • Touch Screen + Hard Buttons • Touch Screen programmable

  17. X-10 and A.V. Systems Integration

  18. Complete Control Systems • The high-end • Complete systems integration including theatre, lighting, security.
