720p Vs 1080i HDTV

Is 720p vs 1080i worth being concerned about? Yes and no. If you're a consumer looking for a new TV, you can happily ignore the 720p vs 1080i debate because every TV which is described as HDTV or HDTV Ready is required to support both formats.

Surround Speaker Mount

NOTE: You should be aware though that lots of TVs which support 1080i have fewer than 1080 lines and so scale the 1080 signal down. That's not a huge issue as even scaled down 1080i is far ahead of a regular NTSC signal. It is worth bearing in mind that more expensive HDTVs tend to have better scalers than cheaper ones, and this may be an issue.

However, for broadcasters it's a live issue. Should they broadcast 1080 lines of interlaced video or 720 lines of progressive scan? They could just broadcast two signals, one in each format, but that would use up a huge chunk of bandwidth and be hugely expensive for very little gain.

To answer the question, it's important to understand the difference between 720p vs 1080i. A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know as progressive scan (hence the 'p')The quality is like watching 30 photographic images a second on TV. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the 'i'), ie every other lines is displayed for 1/60th of a second and then the alternate lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously.

Most of the time interlacing works fine, but for fast moving images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' effect on-screen. Progressive scan signals don't have this problem and so are better suited to sports.

ESPN puts it like this: 'Progressive scan technology produces better images for the fast moving orientation of sports television. Simply put, with 104 mph fastballs in baseball and 120 mph shots on goal in hockey, the line-by-line basis of progressive scan technology better captures the inherent fast action of sports. For ESPN, progressive scan technology makes perfect sense.'

Bottom line? For us, as consumers 720p vs 1080i is not a debate worth worrying about, so you can relax and focus on all the other criteria on your list when you buy your next HDTV.

What Matters in an RS232, RS422, RS485 Or Fiber Optic Converter

Anyone dealing with serial and USB conversion issues knows that data signal conversion between different protocols can be tricky. Serial data communication originated many years before we came to expect the plug-and-play convenience of modern systems and interface standards. In the past, determining if a device was DTE (data terminal equipment) or DCE (data communication equipment) was an issue, you had to deal with handshaking protocols, and you needed a fairly detailed knowledge of all the various signals. Today's USB, RS232, RS485 and RS422 converters, in conjunction with much smarter software, make things a lot easier, but it's still good to know what you're dealing with. So here are some answers to commonly asked questions.

Surround Speaker Mount

You may see converter vendors advertise SMT circuitry as a selling point. SMT stands for Surface Mount Technology, which allows for significantly smaller currents and thus less heat. Less heat means longer component life and thus higher reliability and lower total cost of ownership.

Surround Speaker Mount

Another question that frequently comes up is whether you can unplug a connector while it is being used. The answer is yes if the converter has a data receiver protection circuit. If you need your converter(s) to be hot-pluggable, make sure whatever you buy offers data receiver protection.

Anytime you deal with converters, you may need end-of-line termination so as to prevent interference on the data line. The problem is that termination increases the load on the data circuit, so it's generally best to use a terminator only at higher data rates (over 19.2hbps or on lines over 200 meters).

While RS-232 cables are pretty standard, people often ask what kind of cable to use for RS-422 and RS-485 connections. The answer is that in most cases inexpensive CAT 5 cables will work just fine. They generally exceed RS-422/RS485 recommendations and are an excellent choice.

Technology changes all the time, and one thing that has changed is the power of COM ports on new computers. Older systems used -12VDC whereas most newer ones use -8VDC. Before you buy, check converter specs to make sure they support the lower voltage. Many new laptops, and even some new desktops, no longer have serial ports and require USB-to-RS232 cables that create a "virtual" COM port. Converters generally work with those cables, but it makes sense to inquire before you buy a converter.

Almost all electronic circuitry is sensitive to electrostatic discharge. The charged capacitance of a human body is actually enough to destroy an integrated circuit in an instant. That's why good converters have static protection circuits. Note, however, that those are not surge suppressors. If you have an outdoor installation, you want to use an opto-isolated converter to protect your computer. Opto-isolators (which, however, require additional power supplies) work by inserting an optical bridge that eliminates transient surges.

Another question that frequently comes up is whether or not to use fiber optic systems. Fiber optics, of course, use light instead of electricity. This means a number of advantages in terms of higher speed, higher bandwidth, and inherent resistance to EMI/RFI and other electrical or radio interference. Fiber optics are best used for long distance communication, such as when RS-232 data must be sent to remote locations. The overhead consists of a special transmitter, the fiber optic cable, and a receiver. Note that fiber optics systems can be single-mode or multi-mode. Single-mode means a single strand of fiber for distortion-free, high-speed long distance communication. Multi-mode cable uses multi-strand fibers and is more prone to signal distortion. Each cable type requires the proper transceivers. Cables can also use either bayonet-style or push-on connectors.

Any time you deal with USB, RS-232, RS-485, RS-422 or fiber optics converters, it pays to do some research and plan ahead. Companies specializing in converters often have downloadable data sheets for all of their products, and that can help tremendously in getting the proper gear.

Fireplace Installation of Plasma and LCD TVs - How Do You Do That?

In considering whether you must or must not install a TV above a fireplace, you must consider many aspects of installation. Listed below is a step by step guide in installing flat panel LCD TVs or plasma TVs above a fireplace. The guide would also answer questions regarding the safety of putting up a TV above the fireplace.

Surround Speaker Mount

A. Do you have plans of using the fireplace again? If yes, then proceed in reading this article for you to learn if you'd want to install your TV above your fireplace. On the other hand, if your answer is no, well certainly you could install any plasma or LCD TV above your fireplace for as long as your wall could support the weight of the mount and of the TV.

Surround Speaker Mount

B. Use a thermometer above your fireplace on a mantel where you're going to install your TV. Get your fire going in full force, if it does not get to or above the TV manufacturer's heat level recommendation, then you are good to go at 90 degrees. If you do not have a thermometer, get your fireplace blazing hot then touch the wall above it to see if it's warm enough and is just okay. If it's too hot to touch, then you probably could not install your TV there.

C. Another consideration aside from heat above the fireplace would be the mantel wall, you'll need to know if the facade has brick that is actually a part of your chimney. If it is a part of your chimney, if you've done a heat test, it should be hot. Most homes built from the 70's have facades. If your fireplace has brick facade, heat is put to small smoke stack that's insulated from heating the surrounding walls. This would protect you from chipping paints and drying walls from totally deteriorating.

D. When you are not sure, call a professional to be able to determine if you could hang your TV above your fireplace. HD installers have installed more TVs above the fireplace from any other companies in the US. Most of the time you could put an LCD TV above a fireplace, however, HD installers will not install big screens if they determine that it is not safe.

The Sound Is As Important As The Picture Of Your TV

Looking at that plasma television, or LCD or DLP television mounted on the wall, what is it missing? Of course you have HDTV connected in some way or another through cable or satellite, but what about the sound? Do you have the surround sound system that makes the entire set-up pop? What good is a great picture if the sound isn't at the same quality level?

Surround Speaker Mount

What do you enjoy about going to the movies besides stepping in sticky stuff as you make your way down the aisle and into your seat? The previews are always a great part of the experience, but the rude kids in the back aren't, so what is missing? Of course it is the big, booming sound that makes you feel like you are in the movie. When there is an explosion on the screen, you expect to feel it. When a rocket blasts off and pushes its way through the atmosphere and into the silence of space, you want to be along for the ride and hearing what is going on is half of the experience.

Surround Speaker Mount

Feeling the rumble and shake and the deep bass of the speakers in the movie theater is part of the experience that you are paying for and part of the experience that make its memorable and enjoyable. So why not have that same experience in comfort at home? You already have the great looking television, now all you need is the great sounding speakers.

While the speaker quality that the manufacturers are installing in their televisions has gotten better, it still doesn't compare to what you can get on the aftermarket or what you should get on the aftermarket. Now, that doesn't mean that you have to go overboard, and if you live in a condo or an apartment, your neighbors will be happy that you didn't go overboard, but you need something that fits the television and fits the room that you will be enjoying that television in.

If the room is large, then you probably need a little more power, if it is a dorm room or a small bedroom, then you definitely don't need to pay for more power if you are never going to be able to use it. This is all pretty evident, but sometimes it's tempting to pick out something that is much bigger than you actually need, just look at that television hanging on the wall.
