Call C.I.S. To Discuss The New Lutron RadioRa2 Product Line And How It Can Benefit Your Lifestyle

Energy-saving daylight sensing added to Lutron lighting and shading control.

Lutron Electronics has announced product rollouts that will take place this year and next, designed to provide total home control and energy management, mainly via its new upscale HomeWorks QS wired and wireless lighting systems and its mid-market RadioRA 2 wireless lighting solutions.

“We’re really going to focus on control of energy in the home,” says David Weinstein, Lutron’s vice president of sales.

For the first time, HomeWorks QS and RadioRA 2 will feature daylight sensing to automatically adjust lights and shades, based on the amount of sunlight penetrating a space. Occupancy sensing, which Lutron says can save 20 percent or more in lighting energy by automatically shutting off lights when no one is in a room, is also a part of the systems.

Lutron has used daylight sensing in its commercial products, but for the first time is introducing the technology into its residential lines.

Most automated shading in homes is accomplished by programming astronomical clocks to descend shades at certain times of the day to help keep a room cool—or do the opposite to help heat a room.

Lutron’s daylight sensing solution could also enable daylight harvesting—using the natural light to illuminate a room and reduce the need for electrical lighting.

Up to now, electronics installers had to use third-party sensors, and the programming required could be complex, explains Lutron product development manager Richard Black. Installers often used contact closures that descended or raised the shades at certain daylight thresholds. That was a simple solution to a complex issue, so when clouds passed, for example, motorized shades could go up and down too frequently. “There are a lot of settings you have to have to make that work effectively. Now that we have the logic, we can make it work better.”

Lutron also announced Venetian blinds with intelligent tilt alignment, as part of its Avant line. Lutron says the product can tilt the blinds seamlessly, and the company will look to integrate automated tilting via daylight sensing as well. The system can also adjust height of shading as the angle of the sun changes.

Chief among Lutron’s other product announcements are:

-A plug-in appliance module coming in December 2010 to monitor and control appliances are other energy loads in a home.

-Dynamic keypad coming in April 2011 that controls lights, shades, HVAC, audio/video and energy from one spot.

-Venetian wood blinds with intelligent tilt alignment.

-seeTemp intelligent thermostats coming in April 2011.

-An Eco Button that can dim lights and set back the thermostat plus or minus 2 degrees to save energy.

-Integration with iPad and iPhone.

-A phase-adaptive dimmer that automatically senses the load—whether its CFL or LED, for instance—and adjusts the dimming for that.

-A Green Button coming in April 2011 that dim lights, lower shades, sets back temperature, and turns off unneeded appliances via plug-in appliance modules.

-An iPad app in Dec. 2010.

“By adding cooling and heating, in addition to lighting and shading and connected loads, we can control 60 percent of the energy use in the home,” says Weinstein.

Analog Sunset

CIS is Charlotte's Source For Technology Questions and Answers

CIS is Charlotte's Source For Technology Questions and Answers

How concerned should integrators and consumers be about restrictions on component video outputs affecting Blu-ray players?

The impending so-called “analog sunset” has been touted as the next big thing affecting the custom electronics industry.

Whether or not that’s hyperbole, it’s certain that there are things integrators need to know about restrictions being imposed by the Advanced Access Content System (AACS) licensing agreement — especially in regards to Blu-ray playback.

If savvy clients haven’t already begun asking questions about whether or not they should throw out their component cables, they soon will. Integrators need to know what to tell them and how to react.

Right now integrators can allow clients to view content off Blu-ray discs using an analog component video output on a Blu-ray player. But according to the AACS licensing agreement, after Dec. 31, 2010, no new designs may be introduced with hot HD component outputs; existing designs can be manufactured and sold through Dec. 31, 2011. No Blu-ray players with hot HD component outputs may be manufactured or sold after that date, but they can still output SD resolutions through 2013.

That doesn’t mean that you can’t use Blu-ray players made before Dec. 31, 2010, for viewing content off Blu-ray discs using an analog component video output. Meanwhile, in-stock models made before Dec. 31, 2010, with component inputs capable of HD output can continue to be sold through 2013.

“I recently heard a competitor state that they were going to purchase as many older [Blu-ray] players as they could afford to put off dealing with the changes for as long as possible,” says CEDIA chairman Ken Erdmann, owner of Springville, Utah-based Erdmann Electric. “That will not solve the problem and is rather shortsighted.”

Indeed, after January 1, 2011, Blu-ray disc makers can include an “Image Constraint Token” (ICT) that disables HD over component video down-converting the HD capable input to SD while that particular disc is in the drive. Existing discs in a customer’s collection without the ICT, however, will continue to provide HD component output with no change. The token is only disc-based, so discs with no ICT will operate the same as always (allowing 1080i component out).

Erdmann speculates that Blu-ray titles released years earlier could even “include ICT for those titles manufactured after the 2011 implementation date. A client could be very unhappy if they were used to watching a favorite title for years that when they replaced the worn or damaged disc with a newer version of that title it no longer looked as good or possibly would not play at all.”

Is Analog Fading to Black?

“Analog Sunset” is a term that is actually used in the AACS license agreement: ANALOG SUNSET – 2010. With the exception of Existing Models, any Licensed Player manufactured after December 31, 2010, shall limit analog video outputs for Decrypted AACS Content to SD Interlace Modes only. Existing Models may be manufactured and sold by Adopter up until December 31, 2011. ANALOG SUNSET – 2013. No Licensed Player that passes Decrypted AACS Content to analog video outputs may be manufactured or sold by Adopter after December 31, 2013.

Source: The AACS Final Adopter Agreement, available at http://www.aacsla.com.

At the very least, this legal language will leverage installers with some frustration, according to Fred Harding, who does sales and technical support for distributor Capitol Sales.

“It will cause stress for folks who are installing Blu-ray players over the next year who aren’t prepared. Worst case will be down the road, when manufacturers of other HDMI-equipped products stop putting analog outputs on their devices based on economic decisions. In that case, it will be the absence of connections rather than a mandate that hurts. I’d start planning if it were me.”

However, points out Trent Davis, Audio Authority’s product manager, manufacturers alone can’t always decide when to stop putting technology on their devices. He cites, for example, that many components still are required by the FCC to have FireWire ports even though the technology isn’t commonly used anymore.

Still, the AACS provisions will affect integrators that “have used the component video safety net” because they’ll “be forced to come to terms with the HDMI output,” says Erdmann.

“The loss of 1080i video brought about by the implementation of the ICT will be unsatisfactory to our clients. Even worse, integrators unwilling or unable to deliver the best quality video by using the HDMI output might find their clients looking elsewhere to satisfy their desires for the best quality video and audio in their systems. As time goes by and more of the provisions [are] allowed and implemented under the AACS licensing agreement, the unprepared integrator will face even greater challenges.”

Is the Issue Over-Hyped?

Audio Authority, makers of HMDI and component video distribution systems, switchers and adapters, matrix switches, recently issued a whitepaper, “Component Video’s Future: Demystified,” because there is a lot of misinformation out there, says Davis.

He’s not saying it’s much ado about nothing, but he says the facts are becoming blurred amid all the speculation.

The bottom line, according to Audio Authority, is that component video isn’t going away — but its role will be changed, even mitigated. “Some content sources will be experiencing some changes in the way they are required to control component video output, while others are under no threat from pending restrictions,” writes the company.

Extron Electronics, a manufacturer of A/V components including matrix switchers and cables, also issued a whitepaper on the topic, “Analog Sunset Demystified.” The company’s stance is that even with the impending restrictions, “use of legacy components already installed or the design of systems using products that both have analog and digital outputs will be around for quite some time,” says Joe da Silva, director of product marketing.

“A/V integrators have the choice to design systems using a ‘hybrid’ approach or transition all signals to a digital format. The hybrid design for digital and analog distribution can be much more cost effective than an all-digital approach. A/V integrators who incorporate high-definition protected content and playback of Blu-ray disc format into their designs will certainly be influenced by the restrictions associated by AACS provisions.”

What about Content?

The ICT has actually been around for a while, Audio Authority points out, but it’s not known to have been used on a mass-released Blu-ray disc. Let’s take a look at AACS’ specific ICT and Digital Only Token (DOT) language:
SEC. 3, 1.3.2 Content Participants/Providers shall not, prior to December 31, 2010, direct Licensed Content Producers to embed the Image Constraint Token in Licensed Content Products offered for sale or other distribution in a country in which there was a government or quasi-government regulation or equivalent prohibiting the use of an Image Constraint Token, or equivalent, for scrambled or encrypted content as of November 30, 2005.

SEC. 3, 1.4 If Content Participant/Provider has directed that the Image Constraint Token and/or Digital Only Token be set with respect to a particular LCP (Licensed Content Product) Unit, then the fact that such Image Constraint Token and/or Digital Only Token (as applicable) is set shall be disclosed by the Content Participant/Provider to the consumer either (i) on such LCP Unit’s product packaging; or (ii) only in the case of a consumer product, by other reasonable means that allows the consumer to be aware at the point of initial purchase that the Image Constraint Token and/or Digital Only Token (as applicable) is set with respect to such LCP Unit.

1.2.1 Content Participant/Provider may assert the Digital Only Token only with respect to (a) Non-Consumer Products and/or (b) LCP Units Released in a given country within the first six (6) weeks after the first Theatrical Release of substantially similar Digital Entertainment Content in such country, provided that in the event of the circumstances set forth in this part (b), within six (6) months after such first Theatrical Release, Content Participant/Provider shall Release in such country LCP Units containing a version of such Licensed Content Product that does not assert the Digital Only Token.

Audio Authority points out that the DOT only applies to non-consumer content and for licensed content released on Blu-ray disc within six weeks of the theatrical release “with the caveat that non-DOT versions of the content must be released within six months.”

The effects on Blu-ray, however, while significant, aren’t the entire story. Speculation abounds that the AACS licensing agreement affects cable and satellite boxes, media streaming devices, gaming consoles, media centers and computers.

It’s not true, though, says Davis, unless those devices include Blu-ray players. “A DirecTV box, for example, is not an AACS licensed device and is not affected at all by the provisions of the AACS Analog Sunset. It is, however, affected by the FCC’s SOC [Selectable Output Control May 2010] ruling, but the FCC is the authoritative body in that case, not the AACS licensees.”

So, with some help from Audio Authority’s whitepaper and other authorities, let’s take a look at effects on different content sources.

C.I.S. - "We may be a few dollars more than the competition, but we are a million times better."

Cable, Satellite Boxes

These content sources shouldn’t be affected much by the AACS licensing agreement, according to Audio Authority. The Federal Communications Commission (FCC) oversees these components and federal law disallows content providers from turning off component video outputs.

The one exception to this rule, Davis says, is the aforementioned SOC ruling. It “allows deactivation of set-top box analog outputs for very specific content: first-run movies that are still in theaters.”

Meanwhile, the FCC also tells cable and satellite companies not to allow commands to turn off component outputs from being including in their content delivery signals, preventing content providers from restricting output on their own.

So component video should remain applicable to cable and satellite boxes. However, that could change, Harding says. “I think in the future the cable and satellite boxes will drop the jacks based on manufacturing savings. I’m suggesting worrying.”

Erdmann takes a similar stance. “It is my opinion that there is nothing stopping content owners from imposing similar requirements on any provider wishing to provide 1080p video,” he says.

“ICT is inserted in the data stream that allows the decoding of the video and which resolution is allowed where. Any non-HDCP-protected output on any cable or satellite box could have ICT implemented on it. It wasn’t too long ago that we started losing RF outputs on high-definition cable boxes.”

Erdmann has the same skepticism regarding the DOT provision. “I know that DOT is reserved for new business models, but who is to say that cable and satellite high-definition programming would not fall under these new business models? DOT could be used to set day-and-date release information or to limit high-definition content in places where DOT was not in use.”

Davis disagrees that there is nothing stopping content owners from imposing restrictions. “Since the FCC regulates analog outputs of set-top boxes, there’s no reason to believe these sorts of changes will be allowed, and they’ll certainly not go unchallenged. It’s not a decision that’s exclusively in the hands of manufacturers. For example, the FCC made a ruling in 2004 that required FireWire ports be included on future set top boxes, despite the objections of content creators and cable companies.

“The ICT and DOT simply do not and cannot affect cable and satellite TV,” Davis adds. “The entire AACS license applies only to products that use AACS encryption. To imply that cable and satellite companies, whose products are not AACS licensed, are beholden to the industry agreement signed by a bunch of other companies is incorrect.

“Selectable Output Control’ is the appropriate term for cable and satellite set top boxes, and that feature is regulated strictly by the FCC. Only one exception has been made — the SOC can be used on first-run movies that are still in theaters,” Davis continues. “Aside from that, content providers have denied the ability to shut off analog HD outputs for years, and the FCC has given no indication they will relent.”

Media Streaming

Vudu, Apple TV, Roku and other media streaming devices aren’t affected, according to Audio Authority.

Component video should remain applicable to media streaming devices, but again, Harding suggests that this could change.

Erdmann adds that, “As long as you are happy with low-resolution video from those devices it probably won’t have an impact. The fact is we hook these devices up to large flat-panel displays and projectors with HDMI, we purchase HD versions of some titles from iTunes. It is unlikely that our clients who are using these services for content will be happy with anything less than the highest resolutions possible.”

Davis, however, says it’s not an either-or issue. “HD video is available from both HDMI and component outputs on these devices and there are no laws, licensing agreements or other regulations in place that will restrict them at this time.”

Gaming, Media Servers and Computers

Although gaming consoles aren’t affected, in theory, by the AACS licensing agreement, some gaming devices play Blu-ray discs, Audio Authority points out.

Sony’s PlayStation 3, for instance, must abide by the terms of the AACS licensing agreement as it pertains to playing Blu-ray content. However, other functions — including video streaming and gaming – shouldn’t be affected.

Media servers and computers, meanwhile, don’t use a lot of analog outputs anyway, but the AACS licensing agreement won’t seem to require shut-off of VGA and component video outputs.

“Our clients will not be satisfied with anything less than the best performance possible,” says Erdmann, referring to gaming consoles, media servers and computers. “They will have Blu-ray video to compare the video these devices output to. It will not be acceptable to them. Most of these systems have Blu-ray in them already, so integrators must be able to deal with the challenges that come with HDMI.”

Power Conditioning 101: Terms You Need to Know

The APC H15 is available at Custom Installation Services! Authorized APC Dealer In Charlotte & surrounding areas

The APC H15 is available at Custom Installation Services! Authorized APC Dealer In Charlotte & surrounding areas

Get to understand what goes into power conditioning as you prepare to add it to your home theater.

 You don’t want to have your favorite pieces of electronics gear wiped out during the next thunder and lighting storm, right? Or perhaps the next heat wave when your local electrical grid is going haywire?

Plus, we’re guessing you want everything to reach its optimum performance, so you can hear everything you should be hearing out of that new set of speakers. 

Power conditioning and protection products are not going to be the sexiest things in your equipment rack, but they could be among the most important relative to their job. They’ll ensure your gear receives clean electricity, and protect your products from potential damage.  And if you’re having a system installed by a custom electronics pro, you can be sure it will include some sort of power product. 

Because it’s an overlooked category, we asked our friends at SurgeX to give us a glossary of what to know. 

1. Alternating Current (AC) – Electric current that reverses direction periodically, usually many times per second. Used for power distribution because the AC voltage can easily be changed by a transformer. 

2. Ampere (Amp) – The practical meter-kilogram-second unit of electric current that is equivalent to a flow of one coulomb per second. 

3. Avalanche diode – A type of semiconductor component that is normally open circuit until the voltage increases to the point where the device turns on and conducts current. Similar in operation to MOVs but do not degrade with use. Very reliable as long as they are used strictly within their ratings. 

4. Direct current (DC) – Electric current which flows in one direction only through a circuit or equipment. The associated direct voltages, in contrast to alternating voltages, are of unchanging polarity. 

5. Brown Out – The IEEE (IEEE Std 1100-1999) recommends avoiding the use of ambiguous terms such as “Brown Out.” 

6. Capacitance – The property of a circuit element that permits it to store charge. A capacitor is an example of one such circuit element. A capacitor has high impedance at low frequencies and its impedance decreases as frequency increases, which allows it to differentiate between signal frequencies in applications such as crossover networks. 

7. Current – A measure of the amount of electrical charge (in Amps) transferred per unit time. It represents the flow of electrons through a conductive material. 

8. Electromagnetic Interference (EMI) – A general type of electric or magnetic interference which is transmitted by conduction or radiation and can be of a very wide frequency range. 

9. Ground – A conducting connection, whether intentional or accidental, by which an electric circuit or equipment is connected to the earth, or to some conducting body of relatively large extent that serves in place of the earth. 

10. Ground Contamination – The diversion of surge and noise currents to the ground wire, which contaminates the system ground. Surge voltages can couple noise to the ground, which can often enter an audio or video system by causing shield current to flow. 

11. Ground Loop – A potentially detrimental loop formed when two or more points in an electrical system that are nominally at ground potential are connected by a conducting path such that either or both points are not at the same ground potential. 

12. Hertz (Hz) – The unit of frequency in cycles per second. Used to characterize anything from AC power (50 or 60 Hertz) up to cellular phone radio frequencies (Giga-Hertz) 

13. Hospital Grade Receptacle – A receptacle which has a high-impact-resistant face and body, and a higher spring tension in the receptacle contacts. Identified by a green dot on the receptacle face. 

14. IEC – (A) IEC stands for the International Electrotechnical Commission: An “organization that prepares and publishes international standards for all electrical, electronic and related technologies.” (B) Commonly used to refer to one of the 13 power connectors described by specification IEC 60320. Most commonly refers to the C13 and C14 connectors used by most computers and many AC-powered electronic devices to connect the AC power. 

15. Impedance – A measure for the manner and degree a component resists the flow of electrical current if a given voltage is applied. It is denoted by the symbol Z and is measured in ohms. Impedance differs from simple resistance in that it takes into account possible phase offset. 

16. Joules – The standard unit of electrical energy (measured over time). One Joule is equivalent to the heat generated during one second when one Volt is driving one Amp around a circuit. 

17. Linear power supply – One type of power supply inside electronic equipment that converts the 120V AC to the DC required by the circuitry. A type of regulated power supply which utilizes a line-frequency transformer. Linear power supplies regulate their output by generating a higher voltage than needed at the output, then reducing it by converting some of the electrical power to heat. 

18. Metal Oxide Varistor (MOV) – A disc shaped device which is normally open circuit until the voltage increases to the point where the MOV turns on and conducts current. Originally developed to suppress arcing on relay contacts but used extensively in shunt-mode surge protectors. Have a limited lifetime. 

19. National Electrical Manufacturers Association (NEMA) – A US trade organization that develops standards for the electrical manufacturing industry. 

20. NRTL (Nationally Recognized Test Laboratory) – A government certified testing agency (such as MET Labs, Intertek/ETL, and TÜV) that tests and certifies equipment to established safety and test standards. Identical in function to UL certification. 

21. Parallel Connection – Devices connected together so that the same voltage appears across all devices. 

22. Radio Frequency Interference (RF) – Interference which is caused by radio signals. 

23. Root Mean Square (RMS) – The value of an AC voltage or current that delivers the equivalent power that a given DC voltage or current delivers. 

24. Sag – An RMS reduction in the AC voltage, at the power frequency, for durations from a half cycle to a few seconds. Note: The IEC terminology is dip. 

25. Series Connection – Devices connected together in a chain so that the same electric current passes through all devices. 

26. Shunt Connection – (Equivalent to Parallel Connection) 

27. Shunt Mode Surge Protector – A type of surge protector which uses MOVs, avalanche diodes or gas discharge tubes to conduct surge current to the neutral or ground wire. 

28. Spike – The IEEE (IEEE Std 1100-1999) recommends avoiding the use of ambiguous terms such as “Spike”. 

29. Suppression Voltage – The maximum peak voltage that will be seen across the active terminals of a suppressor at a specified waveform and source current. It is the remnant voltage the suppressor “lets through” to protected equipment. Products tested to the UL 1449 Standard are assigned a VPR (Voltage Protection Rating) in a range from 330V to 2500V, based upon the product’s suppression voltage. 

30. Surge (Transient) – The IEEE (IEEE Std 1100-1999) defines “surge” and “transient” to be analogous terms, as defined as: a subcycle disturbance in the AC waveform that is evidenced by a sharp, brief discontinuity of the waveform. 

31. Switch-Mode Power Supply – One type of power supply inside electronic equipment that converts the 120V AC to the DC required by the circuitry. A switch mode supply is smaller and lighter than a linear power supply because it switches the current on and off very fast to generate the DC using a small high-frequency transformer rather than a larger traditional line-frequency power transformer. 

32. Toroidal Transformer – A transformer that is constructed around a magnetic core in a toroidal, or donut shape. This geometry produces a more contained magnetic field, which leads to a more efficient and compact design. 

33. Transient – A subcycle disturbance in the AC waveform that is evidenced by a sharp, brief discontinuity of the waveform. May be of either polarity and may be additive to, or subtractive from, the nominal waveform. 

34. Under Voltage – When used to describe a specific type of long duration variation, refers to an RMS decrease in the AC voltage, at the power frequency, for a period of time greater than 1 min. 

35. Underwriter’s Laboratory (UL) – An independent product safety certification organization that writes standards and tests products. Other NRTLs (Nationally Recognized Test Laboratories) may also perform product testing to ensure compliance with standards written by UL. 

36. Uninterruptable Power Supply/Source (UPS) – A device that provides battery backup power for continuous equipment operation when the electrical power fails, drops, or rises to an unacceptable voltage level. 

37. Volt Ampere (VA) – The standard unit of measurement of apparent electrical power, equal to the product of root-mean-square (RMS) voltage and RMS current. 

38. Watts – The standard unit of measurement of real electrical power, which factors in any phase differences between the voltage and current waveforms.
