  1. DTV Transition 2009

  2. DTV Transition 2009 • What the DTV transition means for Radio Mic Users

  3. The TV Spectrum • Since June 12th, 2009 the ‘Major TV Broadcasters’ have switched to digital ONLY • A small handful of stations ‘volunteered’ to continue for ‘one month’ as Nightlight Stations transmitting at a reduced power level • Nightlight Stations transmitted a tutorial program on ‘How to switch to Digital’

  4. What happened to the Spectrum • Before the final DTV Switch – Broadcasters were transmitting high power TV signals on two separate TV Channels • One Analog and One Digital (DTV) • This took twice as much of the available Radio Spectrum and left no really useable place to work the RF Mics / RFPL / IFB / etc.

  5. Common Questions • You’ve heard DTV will make your Wireless Mic obsolete • That is not correct – the Wireless RF Mic is a frequency dependent device. • It’s very important to choose a ‘clear channel / frequency’ that should have NO active TV Channel broadcast on it

  6. Common Questions • Selecting a set of Frequencies when knowing what DTV Channels are active in your area • Only open (unoccupied) frequencies should be used. • You should not operate a wireless mic on the same frequency as a local DTV Station

  7. Common Questions • Are DTV Stations a ‘BIG PROBLEM’ ? • DTV Station represent an interference problem the same as ANY OTHER transmitted signal. • Avoid choosing a frequency on an active DTV Channel and you have removed a major source of radio ‘hits’ to your system • Consider the ‘White Space Initiatives’

  8. Things that are good to know… • FCC Rules that affect the Sound Crews using Radio Equipment • Code of Federal Regulations Title 47 • CFR 47 Parts 15, 73, 74 and 97 – What the FCC rules actually say about licensing for radio mics • Where and How to find information on what TV Channels are active in various cities

  9. Things that are good to know… • Why care if the Radio Mic is transmitting on an active DTV Channel • Why should the Sound Crew care about the FCC Rules • Why can’t I Transmit on certain TV Channels like Channels 14, 16 and 20 in specific cities in the US • What’s with Channel 37 being blocked nationwide

  10. Things that are good to know… • What is a Spectrum Analyzer and how to read the display screen • What the transmitted signals look like on the Spectrum Analyzer • What’s so special about Coordinating the actual Frequencies the RF Mics transmit on • Why does it matter what frequency the Radio Mics are on, isn’t the ‘Block #’ good enough to work with

  11. Things that are good to know… • What is • ‘Frequency’ • ‘Bandwidth • ‘Intermod’ • ‘Image Frequency’ • Are all the TV Channels Analog or Digital

  12. Things that are good to know… • Radio Mic Operation and use: • Studio / Set Applications and potential problems • Location Shooting • Pros and Cons of various types Receiver Antennas • What’s happens with RF Mic coax, and the distance of the runs to the antennas

  13. Things that are good to know… • Do you need a Receiver Amplifier for the radio signal, if yes – then where is the most practical place to set it up in your radio system. • Mic Placement – is it really that critical • Why use RF Mics for Plant Mics on Set • How can I use different mics other than a Wireless Lav

  14. History of Communications • The FCC

  15. History of Communications • The FCC • Started with the Communications ACT of 1934

  16. History of Communications • The FCC • Started with the Communications ACT of 1934 • Was made to regulate Commercial and Amateur HAM Radio transmissions

  17. History of Communications • Why Regulate and control both Commercial Broadcasters AND Amateur HAM Radio Stations

  18. History of Communications • Because in the early days of Radio…

  19. History of Communications • Because in the early days of Radio… • Many of the HAM’s (Amateur Radio) Stations were more powerful and had a better quality signal than many early Commercial Broadcast Radio Stations

  20. Most people know that if they watch television the Federal Communications Commission (FCC) is part of their life due to its role in regulating interstate and international communications by radio, television, wire, satellite, and cable.

  21. What people may not recognize is the extent to which every area of their life is intertwined with the communications technologies the FCC has responsibility to regulate.

  22. For example, because almost all electrical and electronic equipment emits radio frequencies, FCC equipment authorization rules protect you when:

  23. You play with a radio-controlled airplane, car or boat,

  24. You play with a radio-controlled airplane, car or boat, • Your teenager upstairs sends their homework assignment to the printer downstairs via your new wireless home network,

  25. You play with a radio-controlled airplane, car or boat, • Your teenager upstairs sends their homework assignment to the printer downstairs via your new wireless home network, • You push the button on your garage door opener,

  26. You heat your breakfast in the microwave,

  27. You heat your breakfast in the microwave, • You lock your car with your remote entry system,

  28. You heat your breakfast in the microwave, • You lock your car with your remote entry system, • You activate your home alarm system before going to bed.

  29. These are just a few of the thousands of ways in which the vital work of the FCC helps facilitate what they define as both personal freedom and the public good.

  30. The formal charge of Congress to the FCC can be summed up in less than 30 words –

  31. Ensure that the American people have available, at reasonable costs and without discrimination, rapid, efficient, Nation- and world-wide communication services; whether by radio, television, wire, satellite, or cable

  32. The day-to-day reality may be that there is no more ubiquitous presence in the lives of most Americans than the FCC-regulated communications industries.

  33. What does this all mean ?

  34. What does this all mean ? • It means the FCC is tasked with being the Agency that regulates ALL Radio transmitting devices

  35. What Constitutes a Transmitter • According to the FCC Rules…

  36. What Constitutes a Transmitter • According to the FCC Rules… • Any electronic device that operates at a frequency of Nine Thousand Cycles or higher is considered a transmitter that falls under the FCC’s Regulation

  37. What Constitutes a Transmitter • According to the FCC Rules… • Any electronic device that operates at a frequency of Nine Thousand Cycles or higher is considered a transmitter that falls under the FCC’s Regulation • That’s just 9 Kilo Hertz ( 9 KHz)

  38. Why cover this info: • So you can understand what the FCC actually does…

  39. Why cover this info: • So you can understand what the FCC actually does… • The FCC is a ‘Regulatory Agency’
