High Definition Radio

Just as it has revolutionized the television industry, high definition technology is now changing the way we listen to the radio. high definition radio (HD-radio) makes tuning into your favorite station a whole new experience. Using high definition technology, any station in the country can deliver super, CD-like sound to its audience. high definition technology also makes it possible for listeners to receive information services such as traffic and weather alerts and stock information on their radios.

Pioneered by a company called iBiquity digital, HD-radio was created in response to satellite radio, which, in the mid-90s, posed a real threat to traditional, or analog, radio. HD-radio mixes digital signals and analog signals, a combination that has made it possible for traditional stations to embark on the inevitable conversion to digital. In 2002, iBiquity made its HD-radio technology available to networks around the nation, and many of them jumped at it.

HD-radio offers a host of enhancements to traditional stations, and iBiquity says the following improvements are possible:

-In terms of sound quality, AM radio will sound like FM radio.

- FM radio will have crystal clear, CD-like sound

- Reception will be free of static, free of white noise, and station loss will no longer be a problem.

- special services like On-Demand radio will be possible for listeners with HD-Radio. Wireless services will deliver news and traffic updates.

These upgrades are available to networks for about $250,000. now, about 300 broadcasters are utilizing HD-radio. Thousands more should follow in the next few years. When they do go high def, theyll still be able to broadcast in traditional, analog fashion. The ability to transmit digital signals is a big step for networks, but one that seems inevitable, given the improvements that result. Thanks to HD technology, some stations are now providing different kinds of programming from a single spot on the radio dial.

Fans of traditional radio should embrace HD technology because it delivers better audio quality and more options for listening. HD-radio is also free. Listeners dont have to go through a subscription service to get it, and they wont have to worry about receiving upgrades from their providers. However, listeners will need to purchase special components for HD-radio and find stations that are broadcasting in HD.

Added bonuses with HD broadcasting include the display of weather, news and song info on the screen of the radio. Listeners can also buy music through their HD systems, and theyll have access to special recording options for music. high definition radios are becoming more and more common. Theyre currently priced at about $150. Automobile manufacturers have started to install them in new cars. Plans are even in the works to apply high definition technology to MP3 players and cell phones. What will they think of next?

Choosing Your HDTV Television

To take full advantage of the great number of HDTV stations you can get with your satellite system, you will want a television with a breathtaking picture and mind blowing sound. When shopping for a television today, you have many more options than just a few years ago. From several hundred dollars, to a price similar to that of a new Corvette, you can choose the television to fit your budget and lifestyle.

If you want to watch satellite programming you will need a tv that is at least HDTV ready. Your satellite service provider will supply you with an HDTV tuner. Even if you will not be watching much HDTV programming, there is still a huge benefit to watching a digital television. All HDTV and HDTV ready tv's contain upconversion circuitry that cleans up the picture with even non HDTV signals.

If you watch a lot of movies or dvd's, you might want to purchase a widescreen television. A widescreen tv has a 16:9 aspect ratio screen, as opposed to the traditional television screen with a 4:3 aspect ratio. You can enjoy watching movies on a screen shaped like a movie theater screen, and view non digital programming in a side cropped view, or stretch the picture to varying degrees to fill the screen. All HDTV programming uses the 16:9 aspect ratio.

The least expensive option is the good old fashioned CRT (cathode ray tube) television. It has been around since 1927, and it is the least expensive option. It is built around a single picture tube, and provides excellent contrast and overall picture quality. A higher end picture tube television will actually give a smoother appearance of motion than a flat-panel tv. The primary drawbacks of tube tv's are their immense weight (compared to newer technology), and the considerable depth of the sets themselves, both severely limiting your installation choices. Also, the largest tube television available is 36", so if you need a larger picture, you might want to step up to flat-panel television.

LCD and Plasma screens are the two options available in flat-panel televisions. Both are incredibly thin and lightweight, and can be wall mounted if you choose to do so. An LCD (liquid crystal display) contains thousands of crystals sandwiched between two glass or plastic plates, which are acted upon by electrical current, creating images on the screen. A plasma screen consists of thousands of pixel cells filled with gases that excite phosphors, producing light, and thereby your picture.

The weight of an LCD and a plasma tv are comparable, with the LCD models being slightly lighter in the 40" range. As the screen size approaches 60", the weight of the LCD overtakes that of the plasma screen. The display panel tends to last longer with the LCD than with the plasma models. LCD televisions are not vulnerable to burn-in, also known as image shadowing or ghosting, like plasma screens. burn-in is essentially burned, or worn out pixels in a plasma screen that have been damaged over a period of time and retain color information from static images like network logos, etc... Plasma tv's tend to have more accurate color reproduction than LCD models, and are currently less expensive than a comparable LCD. While the largest LCD tv at this writing is 65", that is likely to change quickly as the technology evolves with the latest innovations in the computer monitor industry. The largest plasma screen television currently produced is the Panasonic TH-103PZ600U103", which boasts a massive 103" screen, and is expected to carry a whopping retail price of about $70,000 when is hits US markets in late 2006.

Remember the old, bulky rear-projection televisions that were almost a yard deep and weighed nearly as much as a VW Bug? Todays digital big screen tv's take up much less space, and a 60" television can weigh under 100 lbs. Digital big screens are capable of brightness that is unmatched by the older CRT televisions, and do not suffer burn-in like the plasma tv's. These digital big-screens also contains a consumer replaceable lamp that restores picture quality to its original brilliance. prices for these sets are very reasonable, usually one half to two thirds the price of a similar sized plasma or LCD television. One disadvantage of the big screen tv's is still size; even with technological advancements, these models take more room for installation than the flat screen televisions, and are not practical for wall mounting. The ideal viewing angle is only achieved straight on, and in a seated position.

For a true movie theater experience at home, a front projection tv may be a good choice. This is a two piece system consisting of a projector and a screen. They offer picture sizes up to 300", and do not include any type of tv tuner, instead displaying signals from a satellite receiver or cable box. The best viewing experience with a front projection setup requires a fairly dark environment, and is definitely not for everyone. However, for cinema lovers, there is no better way to bring your favorite film to life. Pricing for good projectors starts at just under $1000, and screen prices vary according to size, with most models falling somewhere between $300 and $1500.

Whether you watch mainly sporting events, movies, or dvd's, a modern television can give new life to your favorite programming. As technology advances at an astonishing pace, prices for larger and more sophisticated television sets continue to come down. If you do some shopping online and find that you can't quite afford the tv that you want, save money for five to six months; no matter how much or how little you are able to save, chances are you will be able to afford the set you want as prices come down. just don't blow the money you have saved - you might need to build a new room to house the larger set you will be buying in two years.

Six Branches of Yoga

yoga is an ancient tradition from the Eastern world, and these oldest practitioners tended to look at yoga as a tree with six branches. What all six have in common are the asanas (the physical positions and movements), Pranayama (the structured breathing or breath control), meditation and a strong moral code.

1. hatha yoga

In Indian, "ha" means sun and "tha" means moon. hatha yoga refers to these twin energy channels in the body. Its goal is to prepare the body for the more pure state of meditation to come in the 2nd branch. hatha yoga was brought to us by an Indian yogi attempting to purify the body to make it fit for higher meditation. Western yoga is almost completely the hatha yoga branch, and Westerners find mental and physical comfort in the first branch alone.

2. Raja yoga

Raja and hatha Yoga are highly interrelated. Raja means "royal" in Indian, and in the royal tradition, this branch of yoga has eight included branches as follows:

- niyama - self discipline - asana - positions - pranayama - breath control - pratyahara - sensory deprivation - dharana - meditation - samadhi - ecstasy

Raja yoga is often practiced by religious leaders and monastery dwellers. However, anyone can find benefits in the practice of raja yoga.

3. Karma yoga

The basic teaching of karma yoga is that what we do and how we behave today will influence our happiness and fulfilment in the future, or a future lifetime. Understanding this cosmic principle helps us to create our current environment with love and positivity in order to forestall negativity in our future. Practitioners of karma yoga lead a life of selfless devotion and service to those less fortunate.

4. Bhakti yoga

Bhakti is a sanskrit term meaning love of God and mankind. practice of bhakti involves controlling and channeling emotions and having tolerance for all who come into our lives.

5. Jnana yoga

Jnana yoga is the branch of the intellect. Practitioners pursue scholarly paths, usually those of yoga masters or other spiritual traditions. In our Western religious culture, the Jnana yoga practitioner may be likened to the Jesuit priest, the Kabala scholars or Benedictine monks.

6. Tantra Yoga

Tantra yoga prioritizes ritual as the best way to experience the divine. The sanskrit word tantra translates to weave or loom. Rituals in everyday life lead to a recognition of the divine in everyday life which leads, in turn, to a reverent attitude in everyday actions.

Tantra yoga is the most misunderstood of the six branches. The ancient book, "The Kama Sutra" is a well-known example of this misunderstanding of the real goal of tantra yoga. It is a book of sexual positions and techniques, and in Westernized yoga tradition, tantra yoga has become associated almost exclusively with these published sexual practices. Worldwide, however, most schools teaching this branch of yoga recommend celibacy.

When finally understood by Westerners, tantra's ritualizations of everyday events appeal to them. Western civilizations tend to make rituals of everyday events anyway - births, deaths, weddings, going to church, forming clubs, and all the many various ceremonies and celebrations commonly held are all tightly related to tantra yoga rituals.

One of the best things about the six branches of yoga is that you are not limited to just one, or to a series. You can pick and choose what you want to practice when. Follow your own path using yoga as your toolbox.
