A Guide to Digital Video

HDMI, as of today, is much less complicated than DVI, although this new technology is backwards compatible.

A Review of AC Surge Protection and Power Conditioning

SurgeX protection meets the most stringent requirements of the Federal CID, was designed to withstand an unlimited number of category C1 surges as defined by IEEE 62.41-1991, filters out transients, and does not require close proximity to the building-ground to operate with total effectiveness.

A Technical Introduction to Audio Cables

The fact of the matter is that cables do alter the sound going through them, and that it is audible. You do not need to be an expert, or an audiophile, to hear the difference.

A Whole House High Definition Experience

While the digital dust is settling, consider taking a component video switching approach. Three discrete, HD analog RGB signals can be run down some high quality coax for little more than the cost of the wire.

Absolute Power Sells?.Absolutely!

The power conditioning is a great device to ?clean up? the power and should be viewed as an integral part of the overall system.


The fundamental goal in designing a room for motion picture or music is to achieve the sound at the listeners ears that the producer intends. Assuming a flat response from the loudspeakers, this assumes that the room itself does not distort or otherwise alter the frequency response, the relative amplitude or the time arrival of any sound events.

Add Bass Shakers to Feel the Lows

Everyone?s home theater has bass, but with bass shakers, you can ensure that your listeners not only hear the bass, but also feel it.

Adding Heat to Cold, Finished Rooms A Remedy for the Common Cold

Advanced Video Scaling Technology

There are many issues to consider when displaying an image that was originally produced in one aspect ratio, stored and transmitted in another, and ultimately displayed in a third. Unintended geometric distortions of the displayed image can occur if not processed properly. But, with knowledge of the image?s format and the targeted display, an intelligent video scaler can easily produce the desired results ? and ultimately, an enhanced viewing experience.

Ahhh, jus? phone it in! Nokia?s new camera phone makes imaging easy

Once this camera is in place and cellphone service has been arranged, one may view images directly by email or MMS/SMS messaging to your cellphone. The camera may also be instructed to upload (email or MMS) images upon motion detection or when the ambient temperature moves out of a designated range.

Alternative Big-Screen Displays Carbon Nanotechnologies to Usher in New Displays?

The concept of a nanotube TV will give you image quality similar to CRTs (cathode ray tubes), and the best image quality is still found on CRT-TVs.

Am I getting old? - Have my kids made me senile? How did I lose a 3,000+ pound brightly painted obje

Using basic technology, no cord, no batteries, no Global Positioning System (GPS), high impact plastic, a metal ring and a few pictures, these scientists have developed the C-Car car-finding keychain ? it?s embarrassingly simple.

Ambient Health Dashboards

Introducing a new category of home automation appliance: wireless health dashboards Like a weather station, the Dashboard is modular, and comes in various sizes and configurations. Typically it has between 2 and 5 meters or 4"x4" mini-screens. Each meter displays trends in information about four categories that are relevant to your health: 1) aspects of your environment that influence your health, 2) trends about your body, and 3) a log of health-related behaviors.

An Easy Way to Determine Impedance Match Volume Control Settings

When connecting multiple speakers to an amplifier, it's important to stay above the amp's minimum load requirements. Going below an impedance rating can overheat or even damage the amplifier. Fortunately, stereo volume controls with selectable impedance matching provide this means for protection.

An Introduction to DVI and Digital Connectivity

DVI comes in two ?classes?: single and dual link. Just to make things interesting, it is also important to note that DVI comes in three different ?formats?: DVI-D (digital only), DVI-I (digital and analog), and the so-called DVI-A (analog only).
