The Ultimate HD DVD Home Entertainment Setup

The home entertainment market was created when the VHS was invented; it brought entertainment to people?s living rooms and bedrooms. The VHS progressed to VCDs and DVDs which became the latest in the home entertainment. The cinema theaters, meanwhile, still had their hold on audiences due to certain unique characteristics such as a big screen, digital sound effects, high amplified sounds, and the entire theater experience. There has been a constant effort to bridge this gap between the theater movie experience and that of the home entertainment system. There have been great technological advancements in this field, and the present home theater systems have brought theater quality of entertainment into people?s home with the invention of high definition technology.

High Definition Technology

The HD or High Definition technology comprises of HD Televisions, HD DVD players, and HD DVDs, which when combined with accessories like high quality amplifiers and speaker systems, provide for an exceptional quality of home theater system. The HD technology is relatively new, but has become very popular among consumers. HD equipment may seem to be expensive to the average consumer at first, but with time, as is true with all other types of technologies, these prices will come down as the usage becomes widespread and more advanced technologies emerge.

High definition televisions have already been around in the markets for some time. HD DVD players were rolled-out in Japan in March 2006 by the Japanese electronics giant, Toshiba Corp. This was followed by their inauguration in the U.S. a few days later, and they are scheduled to hit the UK market by the end of April. There is a lot of excitement regarding this technology, and people are expecting to see a revolution in home theater quality.

HD DVD Players and DVDs

The HD DVD or High Definition DVD was introduced in 2005 and was an adaptation of the existing basic structure of the DVD. The HD DVD has a greater storage capacity and can provide better audio and video quality as compared to a DVD. The HD DVDs are integrated with a state-of-the-art content protection technology which is unique to this medium. The storage capacity is 15 GB for a single layer, 30GB for a dual layer, and 45GB for a triple layer HD DVD. It uses the highly sophisticated compression techniques of MPEG-4 for increased capacity. At the core of the DVD format is a blue laser, having a shorter wavelength (405nm) that allows discs to store data at higher densities that are needed for high-definition movies and television. Toshiba has brought into the market two models of HD DVD players, the HD-XA1 and HD-A1, in the United States, priced at $799 and $499 respectively. The new machines are expected to breathe new life into the home video market and change the way people perceive home theater.

HD TV

The large screen plasma TVs and the LCD TVs have already been in the markets for some time and are widely acclaimed to have achieved high levels of quality. These are TVs that have a wide, flat screen that minimizes visual distortions dramatically. A large variety of screen sizes are available in display sizes ranging from 20? to 65?. They come with very high resolutions varying from 1024x768 pixels, 1280x768 pixels, 1366x768 pixels, and 1024x1024 pixels. The HD TVs are equipped to provide higher levels of brightness and contrast ratios. Brightness can vary from 450cd/m2 to 1,200cd/m2, while contrast ratios are 400:1 to as high as and 10,000:1. All these attributes provide for a greater picture resolution and result in very clear and well defined visual quality.

The audio quality is as important in the audio-visual medium as the picture quality. There are a lot of options available in the market that can constantly cater to high quality listening experience. There are three main systems used in the surround sound system; Virtual Surround, Dolby Digital, and the DTS system. For televisions that are not HD compatible, provisions can be made to make them HD-compliant by minor modifications.

The major brands selling HD TVs in the market are Sharp, Panasonic, Samsung, Sony, Pioneer, Philips, Toshiba, and several others. HD TVs are available in a wide price range of $2000 to $5000, depending on the technology, brand, and features available.

Amplifiers or Home Theater Receivers

The amplifiers or home theater receivers are the hub of a home entertainment system and provide high quality digital-to-analog conversions. They decode and process any type of program material or surround mode of audio. They are capable of passing HD signals by converting all S-video and composite video inputs to the component video. Certain receivers also provide features like digital video recorders that enable viewers to watch and record programs in HD picture quality. The price range of digital amplifiers can vary from $300 to $750.

The Dolby system and the DTS (Digital Theater System) are currently very popular in both the home theater and the movie recordings. The first Dolby digital format (AC-1) was used in 1984, followed by the AC-2 improvement that was used for cinema. The latest, Dolby Digital (AC3) arrived in the cinemas in the year 1992. With the advancements made in the digital technologies, Dolby was later introduced in home theatre systems.

At present there are Dolby 5.1, 6.1 and the latest Dolby 7.1. These names are based on the number of channels provided. These also come with a great variety of speaker systems that include home theater subwoofers, speaker kits, in ceiling, in wall, book shelf speakers, center channel speakers, and floor standing speakers. They are available in a price range of $350 to $1500.

The overall effect of a home theater system is greatly influenced by the type and placement of speakers and the acoustic quality of the room in use. The right equipment combined with the right type of room make for the ultimate home entertainment theater.

Do You Need a Subwoofer?

Since it is tough for small-sized loudspeakers to reproduce frequencies under 40 Hz, and really tough for under 100 dB, people often choose to use a loudspeaker just for this purpose. Hence the subwoofer, a kind of loudspeaker that reproduces bass frequencies ranging most generally from roughly 20 Hz to around 200 Hz. DO you need one? Depends upon how well you want to hear, if your sound is reproduced under 40 Hz.

Subwoofers? drivers, known as woofers, average between 8 and 15, and can run 34 even. And drivers begin at 4; those under 8 generally don?t reproduce lower frequencies with good quality.

Use high-powered amps with subwoofers and an electronic crossover and low-pass filter. There are two types of subwoofers; those with an amp in the subwoofer cabinet (active), and those without the amplifier (passive).

Home Theater

With regards to the use of subwoofers in home theater systems, they come mounted in a sealed enclosure. Some people like to focus attention of their systems around satellite speakers, hiding their subwoofer; hence it may be packaged within the system. Others build the subwoofer into the theater cabinet.

Why the separation? To keep them out of site, for one thing. Plus for sensitivity issues dealing with the areas? sound compatibility and mode. Some people prefer to place the subwoofer near the listener.

Bottom line is, if you want to be able to hear low frequencies, you need a subwoofer. If you don?t care, don?t? worry about it then.

When will this come into play? Lower frequencies are needed with older sound formats, like with vinyl records replaced with digital formats, like CDs, mainly with 5.1 formats Dolby Digital and DTS (where the .1 channel is for the bass frequencies, for the subwoofer), common choice of mixed artists.

Building A Home Theater

Building a home theater is a great way for families who enjoy watching movies on a big screen to save money and provide entertainment at the same time all in the comfort of there home.

A big misconception when you mention the words home theater are they cost to much, but you can have one out of the box for a very reasonable price that in the long run will cost you less than taking the family to the movies every week.

A home theater consists of a big screen TV, surround speakers, DVD, or VCR that duplicate the same experience you would get out of going to the movies.

There a couple ways you can have a home theater. One type home theater is the Out Of Box and the other way is to build your own.

Home Theater In A Box:

This home theater system comes with speakers, surround sound receiver, DVD player, or VCR and some with a DVD/VCR recorder and all you need is the big screen TV, preferably a 27 inch, or larger to create your home theater.

The biggest factor you will notice with In A Box home theater systems is the cost. Some systems you can get for as little as $200.00 which is a great savings when compared to the cost of going out the movies and spending $50.00 plus.

When purchasing one of these systems do not worry about the technical stuff because all the instructions come with easy to follow directions for setting up your home theater.

Although In A Box home theaters are very affordable do not expect perfection in the sound department if you want top quality sound. If this is the case you may want to go a different direction and select your home theater parts separately.

Another factor to consider is that In A Box home theater are not that versatile when it comes to adding plug in components, making multiple connections, or changing the speakers later if you decide you want better quality sound.

Creating A Home Theater Separately:

By creating your home theater with separate components you will save money in the long run and be closer to your expectations of quality and what your needs are.

Start by noting what is the most important to you in a home theater then shop around for bargains and select each piece according to your needs and price you can afford.

Better home theaters have a DVD player with channel programming with special recording features, come with five speakers in the 100 watt range that deliver good sound, sub woofers to pick up bass tones and an amplifier.

When shopping for a quality home theater system do not assume that a high price home theater system is always the best system to buy. For around $700.00 you can get a quality brand name system with DVD and speakers with good quality sound.

When purchasing separately you may want to hire someone to install your system because it can be quite complex for the novice to install.

With either type home theater you can get as extravagant as you want by building a complete theater room, or converting a garage with seating and vending machine, pop corn maker or whatever you desire that is within your budget.

The important thing to remember in selecting a home theater system is your needs. Know what you want in a home theater system and what you are willing to spend for quality and always get a good warranty from the dealer.

Accessorizing And Decorating Your Home Theater

So, you?ve bought the big screen TV, the surround sound speakers and various home theater equipment and you have them installed and ready to go. But what?s missing?

If you?re installing a home theater, you need to think beyond the system components and consider the furniture and accessories you want to add to the room to create a really cool environment for your entertainment pleasure.

Just like decorating any other room, the accessories are what will make your home theater stand out from the crowd. Here?s some things to think about when considering your home theater decor:

1. Think about what kind of look you want in your home theater. If the room is a dedicated home theater, you can pretty much pick whatever look you want. If you want to go with a movie theme, you can do that. If you want Old World elegant with a big screen and speakers thrown in, you can do that too. If the room is serving a double purpose, such as an office/home theater or living room/home theater, then you need to keep that in mind when decorating. Most people wouldn?t want giant, framed movie posters for horror flicks within eyesight of their dining room. And if the room is also used for children?s play, safety considerations might dictate decorating.

2. Choose your theme first - maybe you already have a collection of old movie posters and you want to work around that. Or perhaps, you always wanted an indoor garden of sorts. Either way, picking your theme should be the first thing you do before you rush out to the store to buy accessories. Knowing the theme in advance will help guide the rest of your decisions from colors and wall hangings to furniture and lighting.

3. Start a collection. A popular theme for decorating home theaters is to fill it with old movie memorabilia. This can be really fun to collect and it could even be considered an investment as the items you use may well go up in value. Some things you can collect for your home theater include: movie posters, autographed photos of movie stars, an old fashioned movie popcorn maker, movie props and other memorabilia from old movie ticket stubs to real movie theater seats. One thing to keep in mind when collecting anything is that condition is of the utmost importance so buy the best condition items you can afford. It is better to get 1 item in excellent condition, then to get 10 that are in fair condition.

4. Don?t forget the rooms real purpose when selecting furniture and lighting. Make sure lighting enhances the movie experience. If the room is used for another purpose too, think about a combination of lights to make it work for both instances. Low lighting is ideal for movies, but it?s not so hot for kids trying to do homework on a coffee table. You also want your furniture to be of the utmost in comfort. It wouldn?t be much fun to watch a movie on your expensive new home theater system if you are not comfortable, would it? Luckily, with the selections today, you can get both comfort and style in your home theater furniture.

5. Make your home theater feng shui friendly. Keeping some basic principals of feng shui in mind when designing your room can help you attain a relaxing atmosphere. Don?t put seating with the backs to the doors. Try to set the room up with a nice flow and workable space for walking. Don?t try to cram things into the room that won?t fit properly. Make sure to keep your home theater organized, a room that is filled with piles of junk and a mess will not create a relaxing atmosphere. Instead, it will serve to remind viewers who live in the home of any and all work and projects they need to do. Keep the room decorated and nice, but don?t over pack it with junk. Make sure you hide the wires and have plenty of storage cabinets to put your DVD?s in.

The Top 5 Home Theater Wiring Installation Tips

So now you have your brand new home theater system components sitting in their boxes in front of you and it's go time. You have to somehow connect all of these foreign objects together and make it all work. For many people this is a really intimidating scenario, but actually if you follow a few simple guidelines it doesn't have to be all that difficult. So here are the top 5 tips for home theater wiring installation.

1. This may sound corny but read the manual. I know that there are lots of you folks that prefer to just pick up a screwdriver and dive in, but you cannot believe how much you can mess up by not taking the time here to read the installation instructions through and get a good feel for what you need to do in advance. In fact, you may somehow get the system to work without doing that, but odds are that it will never perform as well as it should simply because a few steps were left out while it was being installed. So save your self the extra grief and just read the wiring installation instruction manual before you get started.

2. Use the correct gauge wire for your installation. Remember that when you have to run wire for longer distances it requires a heavier gauge to be able to successfully transmit the signal. Here is a simple general guideline that you can use: for lengths under 100 feet 16 gauge wire should be adequate, up to 200 feet 14 gauge wire will work and over that you will probably need 12 gauge wire to make sure things work properly.

3. Whenever you are making any kind of home theater wiring installation whether it be from one component to another or from a component to the speakers, make sure that both components are powered off when you connect them. Many is the heartache caused by someone turning on components before making the connections and experiencing high sudden power loads that damage their brand new equipment. Avoid that by always keeping the components powered off as you make wiring connections.

4. Gather your cables and wires together in advance and make sure that they will stretch far enough from each installed component before you begin installation. It's really frustrating to find out that one of your wires or cables isn't long enough after you already have everything else set up.

5. A common mistake that many people make when installing their own home theater setup is stacking the components like the receiver, dvd player, cable box and so on, so closely together that they have no room to breathe. Often they will even put them inside a closed cabinet too, which only compounds the problem. So before laying out your system try to think of a way to provide plenty of air flow between each component which will allow it to run more efficiently, last longer, and perform better.

If you plan ahead to set aside plenty of time for your home theater wiring installation, you should be able to get it done with little problem and frustration if you use the tips provided above.

Can I Afford A Home Theater System?

A lot of us view a home theater system as being something for only the people with lots of money. We see the fun times at the theater, with tiered seating, plush chairs, curtains over the screen and popcorn, hot dogs and drinks in the lobby.

It?s true that only those with plenty of cash (and space) can build their own version of the downtown theater in their home, but that doesn?t mean the rest of us have to suffer with a either going downtown to the theater or making do with the little television in the corner.

Home theater was once exclusively available only to the affluent is now readily available for almost anyone who wants to experience the thrills of the latest movie in the comfort of their own home.

When a person thinks about a home theater, a lot of different ideas might pass through their minds. The fun of watching great flicks at home, the rumble of perfect bass, breathtaking visuals and fun with family and friends.

The one thing that usually doesn?t cross the mind is the idea of saving their hard earned money. Home theaters, after all, can be a very high-priced proposal. When a person contemplates the reality that they are an unnecessary luxury in the home, the outlay seems to be even more awry.

A closer look shows that a home theater system can save a person a large amount of money. It may not always recover its full price tag in savings, but a look at the savings show that a home theater is anything but a extravagant investment.

Did you know that a good quality home theater system can now be had for well under a thousand dollars? If we already have a large enough television, it will cost even less!

You may have to make your popcorn in the microwave, get your cold drink out of the fridge and settle for your favorite recliner chair instead of an uncomfortable cinema seat. You won?t have to put up with the chatting or cell phones of you fellow theater goers, but you can have all the fun and excitement of the home theater experience even if you are not yet one of the income earners.

Home theater isn?t just for the rich and famous, it?s easily within reach for almost anyone!

Consider the price of gas to get to a movie theater. Then consider the price per ticket of each movie. Add to that the probable expenses incurred by purchasing popcorn and soda, or if you are in one of the lucky areas, a cold beer. Tack on the extra cost of some candy to munch on in the movie too.

Now, consider the time you spend going to and returning from the movie and how much you value it. Take that number and multiply it by the number of movies you usually like to see in a year. That is a pretty startling amount isn?t it!

The one time purchase of a home theater system will eliminate most of those expenses. It may also require that you to buy a better quality television or stereo equipment than what you currently have. These better quality products will last longer; not requiring expensive replacement soon will be another area of savings.

The purchase of a home theater system will not only save you money over the long run, but you will be able to watch those favorite movies with theater quality right from the comfort of your own home.

No more going out into blustery weather or blistering heat just to go to the theater.

HDTV? You Aint Seen Nothing Yet!

Remember the Osborn? Or was it the Osborne? Actually, I knew it existed, but didn?t care. This thing was a personal computer. Like we?d ever need one of those? Those new electric typewriters with memory were the rage. THAT was something!

Flash forward and we are upon the reverse engineered UFO goodies. Oh, wait, no, that?s not exactly right.

It?s the dawning of the age of Aquarius, age of Aquarius, Ah QUAR EEEE USSS. Um, no, that was some time ago.

It?s the age of $3 US Gas. Not a good milestone.

The age of HDTV!!! Remember when ?high definition? included the terms ?stems and seeds?? You do? You rascal.

No, this is about High Definition TELEVISION. Personally, I feel the word TELEVISON is so?. Fifties. We need a new one there. So did you jump for the Plasma? Or the LCD projector? The DLP? Have you got the home theater with all the tricked out electronics?

Don?t put your ear directly on the high tech train tracks, then, because there?s another train coming, and you?ll hear it down the line.

UHDV is in the pipeline. On the track. In the lab. In the electron wind. Want to guess? Time?s up. ULTRA HIGH DEFINITION.

Remember the movie where they invent this skull cap that would capture your emotions and immediately the bad guy looped someone having how shall we say ? some very intense happy times? and turned himself into peak experience broccoli? Is that where all this is headed? Not for a while, if ever. HOWEVER: UHDV is close to the detail of 35mm film. With 7680 x 4320 pixels, this isn?t far from the 4K (4,000 scan line) digital projection systems for big-screen movie theaters.

Donald Trump will be able to see how bad his hair looks like never before.

UHDV features 33 million pixels with a 60 frame-per-second (fps) progressive scan format.

NHK, the Japanese broadcasting giant who had HDTV in the 1980s? is behind the UHDV format, but reassures us it may be a long time before home theater UHDV becomes reality. That?s corporate talk for, ?Don?t let the competition know how close we really are!?

With 32 times the bandwidth demands of HDTV, UHDV would be prohibitive for today?s broadcast, cable and satellite technology. NHK?s demo required a data rate of 24 Gbps. That was a few years back in Amsterdam where some people were close to hurling lunch because the moving car video hi-jinx was that real.

How real?

NHK cobbled together a custom camera of four CCD image sensors; then to show the output built a LCoS projector combining four eight-megapixel panels. Data storage, using 16 synchronized HDTV recorders, provided roughly 18 minutes of recording time, using 3.5 terabytes of total capacity and a screen about 12 feet high and 22 feet wide. NHK researchers called this ?the sensation of reality saturation point,? in the hopes of providing a completely immersive experience: 100 degrees of visual field angle, viewing from a distance of three-quarters of the height of the screen (about nine feet) with at least 60 pixels required for each one degree of visual field angle.

And speakers? UHDV offers 24-channel sound, or 22.2, containing vertically arrayed surround sound speakers: nine above ear level, 10 at ear level, three below ear level and two low-frequency subwoofer channels.

The format, according to NHK, is not so much intended for home use as for museums, public spaces and theaters. You tell The Donald.

Once upon a time there was SHOWSCAN. Special effects pioneer Douglas Trumbull had his demo unit in a suburb of Dallas, behind a Chucky Cheese, if memory serves. I saw the demo.

The equipment and the Showscan Film Process of producing and projecting Showscan films are justifiably proprietary and patented. At the time, Showscan?s discovery was hailed as the most significant advancement in film technology since the introduction of sound in the 1929 film ?The Jazz Singer?. (Not the one with Neil Diamond.) However, it remained as little more than a technological curiosity until the company developed new camera, high speed projectors, and built special theaters to showcase the revolutionary Showscan images. There was a catch-22 at work. Theaters weren't equipped for this state of the art projection so they couldn't convince investors to make films in that format. Solution: do it all in house.

I can?t remember the specs but it was scarily real, 3-D, multi channel and way ahead of multi channel? or HDTV. I do remember it ran film through the gate much faster than normal projection speeds.

Today the company?s simulation and specialty theatres are open or under construction in 24 countries around the world, located in theme parks, motion picture multiplexes, expos, world?s fairs, resorts, shopping centers, casinos, museums, and other tourist destinations where somebody wants a rush.

If NHK can even come close, well?

Enjoy your puny HDTV now while you can, citizen.
