Differences Between Analog And Digital TV

When you connect VCRs, DVD players and cable TV to your TV, they will send the same basic type of signal. Unless you already own a digital TV, or even if you have digital cable, the cable box is still converting the digital signal into an analog signal, which defeats the purpose of a digital service. As the analog signals travel through the airways, they are not of good quality, so they cannot support high resolution images.

For example, if you compare a lower quality computer monitor, you will have a better resolution than a standard television set. High quality monitors and high quality digital TVs will improve quality by as much as 10 times better than a standard tv.

If you are receiving a digital broadcast and using a digital TV, you can definitely see the difference to a standard analog tv. One advantage of a digital TV, is you do not have to transform the digital service to analog on a digital TV, so you will get the full effect of a digital broadcast on digital television.

Analog And Digital Baby Monitor Types

Advocates of the baby monitor say that these systems allow parents to better meet the needs of their children, as they can see or hear everything that's going on even when they're out of the room. Special devices placed beneath the crib mattress can even track body movement to alert parents of any abnormal activity or Sudden Infant Death Syndrome.

However, critics claim that even the best baby monitors only provide a false sense of security and have not been scientifically proven to benefit babies or parents. It all boils down to parental preference about whether they want to "spy" on their infants or not.

Analog and digital are the two main baby monitor types. Analog monitors transmit signals straight across a frequency band, much like a radio, whereas digital monitors encode the signal prior to transmission for greater privacy. Generally speaking, the digital variety are top-rated, although there's no guarantee that interference can be completely prevented.

Even video monitors can fall prey to interference, particularly from microwave ovens, so it's buyer beware for many of these products. It's important, then, that parents check the warranty policy to ensure they can get their money back or exchange the monitor system, if need be.

There are many different brands of baby monitor systems available today, with some of the most popular being Graco, Philips and Summer Infant. The Philips SCD 589 ($200) has a ton of features and has had many positive reviews, where customers say they suffered no interference.

The Graco iMonitor ($90) has two parent receivers and is also rated good for reception. Similarly, the Summer Infant Secure Sounds ($50) offers a lot of privacy, without all the special features of the more expensive Philips baby monitors.

For pet owners, the Evenflo WhisperConnect Sensa ($50) will detect motion around the baby's crib to alert parents when the cat or dog is nosing around the crib. The high-tech Mobicam ($190) lets parents tape their video monitoring or watch the videos on the TV screen.

Solving Interference Problems With The Philips Baby Monitor

If you've used cheaper baby monitors in the past, then you know how frustrating it can be to hear sirens, car traffic and other babies coming through your baby's monitoring system. Through all the static, it's hard to hear what's going on.

When you're out of the room, it can be difficult to tell if the baby is screaming because it's too hot or too cold to fall asleep too. If only you could talk back to your baby through the baby infant monitor and tell him/her it's okay! All of these problems are solved with the Philips baby monitor.

Sometimes it can be terrifying to hear a sudden, shrill baby screech. Light indicators are a useful feature on the Philips baby monitor, which lets you keep the volume turned off but still see how loud your baby is yelling, depending on how many lights flash.

To soothe your baby from a remote location, a Philips monitor let you speak to your baby through the parental unit, which functions like a walkie-talkie. You can also cue up five 30-second lullabies from your handheld unit or turn on a night light that projects little stars onto the wall.

One of the complaints with the Philips baby monitor is that the charger function doesn't seem to work. The units often don't hold their charge, causing consumers to have to send back monitor system after monitor system.

The rechargeable batteries get fried, regular batteries melt -- it's all around bad news. Other customers say they avoided this problem by using a separate Sony recharging station, instead of the one that came with their baby monitor.

Many problems occurred when purchasers put regular batteries in the unit and also set it in the charging cradle. You must also see that the indicator light comes on when you set the units in the cradle to ensure it's actually charging.
