The basics of Satellite Radio
Broadcasting digital radio via satellite is not something new and concepts of doings this have been with us for a few years. From the early days of satellite radio, companies like Dish Network have offered digital audio channels as part of their programs. The breakthrough in popularity of satellite radio, however, happened just recently, when the technology became more permissive. Satellite radio was very rare on moving locations, such as boats or cars, mostly because there was the need for some expensive equipment – a tracking dish. This was a strong deterrent which kept satellite radio quite unknown by the general public. Today, however, one can receive digital audio satellite broadcasts by using a small, GPS-like antenna. This greatly increased the feasibility of the satellite radio systems and more and more vehicle owners began considering satellite radios as a good source of music and news.
The birth of satellite radio in the United States
When the U.S. Federal Communications Commission (FCC) allocated a spectrum in the “S” band (. GHz) for the broadcasting of digital radio services in no one thought the amplitude that the system would take in the future. From the initial Digital Audio Radio Service (DARS) things progressed until two companies were given licenses to broadcast digital radio in . These two were American Mobile Radio (today known as XM Satellite Radio) and CD Radio (presently called Sirius Satellite Radio). The fact that satellite radio is nationwide makes it a very attractive media channel, both for commercial and non-profit organizations. The two companies that initiated the development of satellite radio saw the huge potential it had, since it wasn’t confined by the limitations of other terrestrial broadcasters.
Benefits of using satellite radio
Here are some of the most noteworthy benefits of having a satellite radio system:
* No more geographical limitations – since the radio program is broadcast through a satellite you don’t have to switch radio stations every time you leave a certain coverage area.
* The digital quality of the satellite radio has some amazing benefits on its own. There are no noise disturbances that were traditional to FM and AM broadcasts. The transmission is crystal clear and satellite radio receives some valuable points when broadcasting quality is concerned.
* Analog radio stations simply cannot broadcast the full range of sounds available through digital satellite radio.
* Both XM Radio and Sirius Radio can be picked up on all the US territory and they are also available in some parts of Canada and Mexico.
Satellite radio technology
Each of the major satellite radio services uses its own equipment to broadcast the signal to their clients. The competition is tight and customers have to “pick sides” in order to benefit from satellite radio broadcasting. You have to choose your preferred company and purchase adequate receivers for that particular company. Both XM Radio and Sirius Radio provide their clients with different ways of receiving their services. The field where most competition takes place is in the negotiation with the major automobile manufacturers. Both XM Radio and Sirius Radio have deals with the auto industry giants in order to offer their services and equipment as optional on the car models they produce. Other partnerships were created with audio equipment manufacturers, who now offer satellite radio transceivers and matching headsets. The most recent shock in the satellite radio universe was caused by the production of portable MP player-like satellite radio receivers.
The future development of satellite radio
One of the main problems of satellite radio was addressed by the main satellite radio broadcasters. Since you need to be in the line of sight of the satellite to receive the transmission, different problems appeared with mobile satellite radio receivers, especially when different landscaping objects blocked the direct transmission. To solve this, land based devices were installed in order to eliminate the lack of direct satellite transmission. Another interesting aspect related to satellite radios is that they approached their service offers from a different perspective than traditional radio broadcasters. Instead of airing commercials they charge a subscription fee. For many people, this is actually the best alternative, since they get an almost % content broadcast (whether it’s music or talk shows) without the – minutes per hour of annoying commercials. In most cases, the monthly subscription for satellite radio is of around $.
Surround Sound Speakers
When you are building a home theater or surround sound system for your home there are many things that must be considered in order to create the best possible system and solution for the space you have in which to create it. We live in a world where floor space and real estate are premiums and we only give them up begrudgingly. It is very true that the best speakers on the market (even today) are generally stand speakers and they occupy a tremendous amount of prime real estate within your media room or home theater.
For this reason we are seeing technological emphasis placed on improving speaker design and making them smaller more now than at any other time in the history of speakers. This is good news for you as a consumer since it means that there is both emerging technology in these smaller speakers and that you will see lower price in the race to create the best small speakers on the market. For many consumers this offers a win-win situation that is too tempting to pass when shopping. It is important however that you remember to see, or in this case hear, for yourself the quality of these smaller speakers before you make the rather sizeable investment that a good set of surround sound speakers will require.
The good news for those of you are experiencing a little bit of sticker shock over the price tag is that speakers should be the largest investment you make in your total surround sound system by far. They are the most vital components to the overall sound and your entire investment will be wasted in your other equipment if you do not have superior quality speakers in your system.
While the number of speakers will increase the quality and depth of the sound and the overall surround experience, good quality is more important than greater numbers, you can always add more speakers to your collection later. I do urge you to purchase the entire set together if possible however, if you can only purchase (remember there’s a subwoofer involved as well) rather than at first, then I recommend that you do that rather than going with inferior quality in order to get two more speakers.
If you do not purchase your speakers as a complete set you need to make sure that the speakers you purchase later are compatible with the speakers in your surround sound system. In most cases this isn’t a problem if you purchase the same brand and style however if there has been a significant passage of time or shift in technology it could prove problematic.
A typical set of speakers for a . channel surround sound system will include two channel speakers (front left and right), one front center channel speaker, two rear channel speakers (rear left and right) and a subwoofer. A . channel surround sound system adds one more speaker in the center rear and moves the rear left and right speakers of a . system to the side left and right respectively. A . channel surround sound system will add an additional rear speaker and have one on each side rather than one in the center.
The sound is the most important feature of any surround sound system and there are many things that go into creating the perfect sound. When it comes to home theaters and surround sound systems the only way to know for sure that you will be getting what you want for your space is to listen to the sound. You may find that what sounded like sound nirvana in the sound room doesn’t ring so true in your living room. Make sure that the store or website from which you are purchasing has a liberal return policy on components and speakers-especially speakers as they are the most costly components of your surround sound system and the most expensive to replace.
XM versus SIRIUS
The idea of America’s biggest two satellite-radio joining forces has been up in the air for almost four years. Although XM had a year’s start, Sirius came back on the market, eventually with both companies sharing the market in half. So, what’s to choose? XM or Sirius?
First thing’s first. XM and Sirius are based on the same principle, each of them providing music, news, sports, etc. on their channels, but, every service has its ups and downs so we will try to discuss it in this present article. A careful analysis shows that XM Satellite Radio provides a total of streams, where two are premium channels (Playboy and High Voltage), twenty-one are traffic and weather based channels and nine are sport-dedicated ones. On the other hand, Sirius offers a total of streams, the premium streams not being available. Let’s take a closer look now on two – music and news – of the categories that the two major satellites are battling.
Music streams comparison
The number of music streams that both services offer is pretty much the same: on Sirius and on XM Satellite Radio but the difference is not in the number, but in the music genres that the radios offer.
Music – Decades
XM is the absolute champion in providing the music by decades because you can listen to the ’s music, service not available on Sirius. Still, you can listen to the ’s hits together with the current hits on Sirius Satellite Radio, which is an interesting feature.
Music – Country
“Ride’ em cowboy!”. Even if you’re not a cowboy, you can listen to country-related songs on both Satellites. Classic country or country hits are to be heard as well as alternative country or country mixes, the last two features being available only on Sirius Satellite Radio. Regarding the number of streams that both Satellites offer, XM offers a total of five streams and Sirius offers four, the champion in this category being XM due to the quality and the quantity of music being played.
Music – Rock
If you are looking for sex, drogs, and rock and roll, Sirius and XM Satellite Radios can only offer you rock and roll, on a number of streams on XM and streams on Sirius. The rock subgenres are to be found in a large number on the stations, overall each service being very strong in this category.
Music – Dance and Latin
If you want to boogie, you can do that on both Satellites, listening to one of the six streams provided by Sirius or four streams provided by XM. Be careful though, because you can become a clubber maniac! And if you’re strong enough, the Latin pop stream, Mexicana and tropical music streams can really drive you crazy. XM Satellite Radio as well as Sirius Satellite Radio offer three streams.
Music – Other genres
Regarding other genres, both satellites really look up to their prestige, offering hours of hours of music, from Classical to Jazz, even Urban (Sirius feature). Both stations offer high quality tunes, making it worth all the money.
News Streams Comparison
Let’s skip to another interesting topic, news. CNN, FOX, CNBC, Bloomberg, MSNBC and many more news stations are being offered for listening in different languages. The number of streams is again near-by, XM offering a number of news streams, not like Sirius, which offers .
Bottom line
It’s pretty hard to say which station is better, XM and Sirius being tied musically but in news and sports, Sirius holding the edge. To make a little joke, if you are a fan of Stern go with Sirius, if you like Q&A go XM. Anyway, it’s hard to say which one is better, but, what can I say is that both Satellites are worth paying for.
Wireless Security Systems
With crime on the rise, home security systems are a must have. With burglars becoming more and more common, you simply must protect your loved ones as well as your possessions. There are several different types of security systems available for you to choose from. For your home, there are wired and wireless security systems available. Each one has its advantages and disadvantages, along with the differences in price as well.
The driving technology found with both wired and wireless security systems are quite different. Wireless security systems don’t need to be wired through the house; they will instead send transfer messages to the control panel through radio signals. When they were first introduced, wireless security systems were proved to be unreliable when compared to the wired systems. As time went by and more and more people looked into them, wireless systems began to take form.
When compared to wired systems, wireless security systems are a lot easier and more convenient to install due to the fact of there being no wires. Wireless systems can save you a lot of money, time, and effort due to there being no ripping of the floors or walls in your home. Wireless systems on the other hand are more expensive than wired systems and you’ll need to replace their batteries on a periodic basis. The primary advantage to wireless security systems is the fact that they are easy to relocate, meaning that you can easily shift them from one home to another.
Wireless security systems use the same components as other security systems such as the touchpad, control panel, cameras, detectors, and alarms. Wireless systems rely on radio frequencies that are transmitted by the door contacts, windows, and motion activated sensors. The touch pads that are located at the entrances to the home will provide activation and deactivation of the system. In the event of the power failing, a backup system will take over the wireless system and continue to provide security for your home.
To use a wireless system, all you need to do is input the code through the control panel. Normally, this is done prior to entering and leaving your home. Once the code is input into the control panel, the control panel will send remote signals to the rest of the system that will activate the alarms. Depending on the system you have, an alarm will go off either by motion detection or a window or door being opened.
If you look around you can find several different wireless security systems, many of which you can install yourself. Before you buy a system though, you should always consult a professional who can survey your home and suggest the equipment you need. Even though it may cost a bit more money, it will be more than worth it down the road.
What next?
So here you are. You have taken that step and
purchased your dream TV, the plasma screen, and now
you have to decide exactly how and where you are going
to mount it.
First considerations are the size of the screen. Can
it be wall or ceiling mounted or would you prefer for
it to be free standing?
There are several types of fixing that will enhance
the appearance of the screen. First, the wall mount,
which will add about two inches to the depth of the
screen. Mount at eye level for maximum effect.
Perhaps you will be mounting the screen over a
fire-place or in a bedroom (often and higher than eye
level), then you will need the tilt fixing which will
tilt the screen to exactly the right angle for easy
viewing.
The table mount lifts the screen up to four inches off
the table but does look rather sleek and stylish in
today’s modern setting. There is also a cart onto
which a screen can be affixed – great for hospitals or
boardroom meetings – with shelves for video, DVD and
computer connections. The cart can be pulled right up
to the boardroom table enabling all to see the images
at the perfect angle.
Ceiling mounts are available for where space is
limited but is usually used in commercial settings.
There is also an articulated wall mount for the same
purpose but the screen can be pushed flush to the wall
when not in use.
The right mount will add a new dimension to your
plasma screen and will look great in any setting.
Why You Should Use HD Cameras
If you own a camera, as millions of us around the world
do, your probably aware of the fact that there are
many to choose from. The cameras of the past were
black and white, enabling you to take a black and
white photograph that printed out from the camera
right in front of your eyes.
From then, cameras evolved. Digital cameras came
out later on, which the ability to put them on your
computer or even take your camera card to a local
store and have the photos printed out on professional
paper. Over the years, cameras have evolved in so
many ways that it isn’t even funny.
These days, high definition video cameras are
dominating the market. They are relatively new and
quickly catching on, giving you so much you can do
with your camera. Unlike the past, cameras are
now capable of capturing full videos as well, proving
that they are indeed capable of capturing any
memory you can possibly imagine.
High definition video cameras also offer you 20X
zoom lens or more, meaning that you can zoom in
quite a distance on things that you want to capture
up close and personal. For the most part, you can
do things with these cameras that you may have
never before thought possible.
When you capture a picture or video with high
definition cameras, you’ll be very amazed at what
you see. Just like HDTV, the pictures of the
camera are very lifelike. If you have a newborn
baby, a high definition video camera may be just
what you need to capture each and every precious
moment. For this reason and many more, you
shouldn’t hesitate to get a high definition video
camera – that is if you don’t own one already.
Rent Or Buy HD Video Camera
If you are new to HD video cameras, you’ve probably
found yourself wondering if you really need to have
one around. For a majority of people, a HD video
camera represents the best way to capture memories
and pictures with the best technology available today.
For producers or those looking to start their own
productions, HD video cameras may be easier to rent
than to buy. While most HD video cameras cost quite a
bit of money, they may be easier to rent than just to
go out and buy.
If you only plan to use your camera for a few days
or just a short period of time, then renting may be
your best option. Producers and professional
photographers looking to take things to the next
level, may choose rent a HD video camera to test the
waters before making the purchase. If you’ve never
experienced HD before, renting a camera may be the
best idea before you sink a ton of money into buying
one of your very own.
On the other hand, if you take a lot of pictures and
enjoy making videos, buying a camera may be the best
option for you. Even though they cost a lot of money,
these cameras are ideal for anyone who is seeking the
absolute best in technology. These cameras are
nothing like cameras of the past, as they can do so
much more – with a lot better quality.
For the average photographer, a HD video camera may
not be the best purchase. If you are on a budget or
don’t have a lot of money to spend, then this type of
camera is probably going to be out of your league. If
you have a lot of money on the other hand, this type
of camera is more than worth the purchase.
There are several companies that rent out HD cameras,
from many different manufacturers. Normally, those
that rent are looking to try the camera out, or just
needing it for a brief amount of time. Trying out
the camera is a good thing, although it normally leads
to buying it. It can be very difficult to try out
a camera that is this good then not buy it.
When the time comes to test out HD video cameras,
renting is sometimes the best way to go. If you’ve
used these types of cameras in the past, then you
may want to go ahead and buy one. There are several
to choose from, and you really can’t go wrong with
jumping on the band wagon and immersing yourself in
the amazing world of HD.

Plasma lifespan
It used to be said that the new plasma televisions
don’t last as long as normal, and more affordable,
TVs. Well this myth can be laid to rest since some
manufacturers guarantee their sets for up to 60,000
hours of viewing time! That is about twenty seven
years in most homes.
Then there was the story that if you kept the same
image on the screen too long – for an example, a video
game image – then the image would be ‘burned’
permanently onto the screen.
You would see a ghost like image after that. To some
extent this is true, however, after several years of
improvement it was found that the image would
disappear after some time when a moving image was
projected onto the screen.
Considering the price that these screens go for, it
would be a good idea to make sure it has everything
you need. Check how many inputs it has to enable you
to connect your DVD, video, computer etc.
There is nothing worse than scrabbling around pulling
cables in and out of the screen – and it doesn’t do
the screen much good either!
Also, consider the sound quality that you require.
Many sets come with standard speakers or clip-on
extras. Some people prefer to connect the sound
through their own high quality music systems.
It seems a little outrageous that these plasma screens
can cost as much as a second-hand car. However, if you
take care to choose the right one, it can bring many
hours of great entertainment at a standard unsurpassed
to date.
Surround Sound Basics
The importance of surround sound is often overlooked when it comes to building and creating home theater systems. You should never underestimate that power that sound holds over all of our television, movie, and sporting event watching experiences. Movie sound tracks are often used in order to create drama, heighten suspense, and even to enhance moods or themes within the movie. Surround sound is for more than mere movies and television however. This great type of sound also serves to bring great depth to our favorite music
Surround sound gets its name from the fact that you are literally surrounded with the sound. This is a vast improvement over the typical two speaker systems in the days of old (oddly enough not all that long ago). Surround sound works to imitate the ambient noises that we often hear during the course of the day. This is often done for the purpose of art imitating life. By hearing the roll of thunder from every side rather than merely the left or the right we are experiencing the real beauty of surround sound and enjoying the more realistic effects it lends itself to.
When you are looking into surround sound systems for your home or home theater you will come across some terminology that may seem foreign and unfamiliar. Surround Sound 5.1 indicates a system that uses five speakers and one subwoofer in order to deliver the sounds. This sound is often referred to as Dolby Digital. A new term that has been cropping up more and more often in movie circles is THX. This is known as surround sound 6.1, which involves the use of 6 speakers and a subwoofer. The center speaker in this system should be located in the center behind the listener in order to add yet another layer to the sound. Surround sound 7.1 adds yet another speaker to the mix in order to create an even more authentic sound. The more speakers in your surround sound system, the more realistic the sound will be and the better able you will be as an audience member to find your place within the action.
In order to get surround sound you need more than a set of speakers. You will first need a receiver in order to ‘receive’ and process the information and send the digital signals and sounds in the direction they should go. If you are building a home theater you will want to make a good receiver a key investment in your overall system. This is an important component as sound is vital to a true ‘movie going’ experience, which is what a good home theater is meant to imitate.
A good receiver is essential not only for a good home theater but also any surround sound system that you wish to install (many people use these exclusively for gaming as well and they are quite effective for this particular purpose). When it comes to gaming, surround sound can identify your location in the action of the game. This works much like it does when watching movies. The more speakers you have in your system the better able you will be to identify from which direction actions, sounds, and such are being made. In games this can provide important clues that those with lesser sound systems will miss out on. Talk about an edge?
While the main purpose of surround sound is to simply enhance the entertainment experience I can think of very few better things to invest in when it comes to either a home theater or the ultimate gaming computer. Do your homework on the systems that are available and remember that good quality speakers are essential in carrying out the sound properly and you should plan to make a sizeable investment in both the speakers and the receiver or other sound components (if you decide to go that route for even better quality sound). Whatever you are using it for be sure that you play around with the sounds to find the best level for your personal enjoyment of your surround sound system.
