How to Wireless Speakers Work?

More and more music lovers are transitioning from the regular conventional speakers to wireless speakers. Regular speakers are still popular and there are people who invested a lot of money in conventional speaker boxes and these are still as great as ever But those in tune with music have began to see a limitation with regular speakers. One of them is the unsightly wires that run from the music receiver or tuner to the speakers. If you have a lot of speakers then the wires can form a tangled mess behind the unit and when it comes time to untangle them the whole exercise can become a major headache. Then there is the risk of someone tripping on the wires and hurting themselves not to mention that if there are little children within the vicinity of the wires they can pull them out and interfere with the sound. In some cases, these cables have started fires in houses and apartments. Thus the strong case to transition to wireless speakers.

Wireless speakers are just normal speakers in appearance but rather than use a transmitter cable from the tuner to the speakers, they rely on radio frequency waves in much the same way a radio or a cell phone works. It is not uncommon to see the speakers, the tuner and a third device whose sole purpose is to transmit the signal. This device, called the transmitter, is connected to the tuner via a cable. An amplifier is also used and this is to magnify the signal and boost its quality. The signal transmitter also has a cable running from it to the electrical outlet on the wall. The frequency range for wireless speakers is the same as that of wireless or cordless phones, about 900MHz. The sound can even travel through walls for a distance of up to 300 feet.

One advantage with wireless speakers is that the sound can actually be transmitted through walls. This means that the speakers need not be in the same room as the tuner. For some, this is especially workable in the event that they want speakers in the bathroom or kitchen or even outdoors. Wireless speakers are also ideal in an zone that has small children or animals in that they can be placed out of range where they cannot access them or interfere with the sound.

Wireless speakers are definitely going to be the way people listen to music in the future even though conventional speakers with their wires are still in use in a lot of homes. One downside of wireless speakers is that they are limited in the distance where the frequency signal can reach. Wired speakers can function regardless of their distance from the tuner as long as the cable can reach them. Also, wireless speakers are subject to sound distortion because the signal is transmitted in the air much in the same way that a radio transmits. This means that if there are other wireless devices within the same vicinity the sound quality may suffer.

New and Improved Digital Cameras

Even digital cameras have evolved over the past few years and useful features have been incorporated to enhance usability. Some pioneering brands like Nikon and Canon have constantly reinvented them on this front and have come out with digitally advanced technologies.

A good photograph depends upon the photographer’s ability and not on the camera. But some of the faults of the digital camera have been hindering the outcome of quality pictures. These shortcomings of the extremely handy digital camera are being constantly worked on. Faults like red eye and reflective images are inherent in digital cameras. Thus features like red-eye reduction are now inbuilt in popular cameras like Nikon digital camera.

The important feature of the digital camera is its ability to view the picture immediately as you capture it. This has resulted in emergence of improved LCD displays. Canon digital cameras have also developed for editing in the digital camera itself. This has made possible to click pictures and edit them immediately as per your need. Digital cameras now also have Bluetooth connectivity for quick transferring of images. Some have also Wi-Fi capability to transfer the image instantly online, this is useful for press photographers who need to release images as fats as possible.

Digital cameras have extendable storage ability unlike film cameras. This helps in storing number of images into the memory card. Now digital cameras support a large memory cards which can offer storage of up to 2 GB. This helps in storing umpteen high quality images and you need not have to worry about lack of space. Some cameras offer face detection, this helps in getting clear images suiting your needs. Cameras are bound to get dust on their lens and this would result in faulty imaging. Some makers have developed a mechanism for removing the minutest dust particle and offering a near complete perfect picture. But such high precisions come at a cost.

You can find digital cameras of all budgets and get the one that meets your needs. You can shop for them online at popular online shopping based websites. They will provide a host of variety and will give detailed description of a product. You can also avail comparison of cameras across brands. You can then choose the one that meets your needs and fits your budget.

Some Points About The Sound Quality Of DVD

DVD or Digital Versatile Disc is a special kind of disc that has a large storage capacity. This disc is mainly used for watching films and music. The sound quality of the Digital Versatile Disc is generally very good. But it depends on the quality of the discs. The more costly the disc you opt for the better will be the sound quality you get from it.

The resolution of DVD sound is better than that of the CD. Even its sound quality is better than that of the CD. It is almost two times better than CD sound. The sound quality of a DVD is very much dependent on the player. To get a good sound you first need a good player. A good player is necessary because only a good player will provide a good sound box. If the sound box is good then it will definitely give a good sound.


DVD sound is mainly of two types. The first is Dolby Digital. It is one of the newest editions in the arena of digital sound. This specific sound is of very good quality. DVDs containing Dolby digital format offer a very realistic sound. This format provides a feeling to the audience that they are experiencing the incident directly, not through a disc.

This format contains one option called surround sound. This gives the listener a feeling that the sound is coming from every direction. Actually in a surround sound format, the sound comes from six different sides. These six sides are, near right, front right, center, near left, front left and the sound that comes from sub woofers. Subwoofers give the sound of low bass. Dolby digital sound is also very popular for films. Many modern cinema halls use this format.

The next is DTS (Digital Theatre Sound). It is a kind of sound that reproduces a theatre like sound. It is almost like Dolby Digital format. However, the sound quality is a bit better than the previous one. This format is mainly of two types. The first is DTS-S which offers four channels. All four of them are matrix encoded. These four channels are, right, left, center, and surround. This system is very much like the standard 35mm optical Dolby stereo. The next is DTS-6 which has six different channels from where sound comes. These six channels are, right, left, right surround, left surround, and subwoofers. This system is very much like 70mm six track magnetic sound.

DTS format is becoming very popular. This format is also used in cinemas. The popularity of the film Jurassic Park also paved the way to its success. The price of this format is also quite reasonable. That is also one reason why people are opting for this system.

If you want very good sound quality from your DVDs, you must have some ideas about the discs. Always buy good discs. Try to opt for the famous brands. The main advantage of good brands is that as they have to maintain a reputation and have to survive in this tough competition, they will never give you any low quality material. It is true that some times they can be a bit expensive. Nevertheless, if you want to get a good output then what is the harm in paying a little more?

Video Goggles Are The New Way To Watch Movies

Video goggles may sound like a futuristic concept, like something out of your favorite science movie, but they are actually one of the most innovative ways to watch movies when you are on commuting on a plane, train, or bus, or when you simply want to watch movies around the house.

The average American spends over 100 hours a year commuting. While most of this commute time is by motor vehicle, a vast majority of business travelers also log in weekly hours on planes, trains, and buses.

The longest and shortest commute states, respectively, are New York and Montana, but when you consider that the shortest is thirty minutes, you can see that this time can really add up, and this statistic does not take into account the time spent by the business travelers and commuters.

This is time that can be spent doing work, reading, and of course, taking a much needed break by watching a favorite movie. In addition, non business travelers in the United States can expect to take at least one plane trip per year, so virtually everyone, then, can benefit from the ability to watch movies privately and on the go.

If you have a video Ipod, you know how convenient it is to be able to download movies online, and take your Ipod with you to watch them wherever you go. Less convenient, however, is the small screen and the sometimes compromised sound quality depending on the type of headphones you have.

Companies that make video goggles have addressed this problem by making eyewear that looks like regular sunglasses, but allows the wearer to watch movies in full screen format, and in some cases, with stereo quality sound. This way, if you don't like the inflight movie, or if the commute has you bored and looking for a distraction, you can literally slip on your glasses and enter your own private movie theater.

You can also use video eyewear to watch movies around the house, which is nice if you want to watch a movie that other people in the house are not interested in. Depending on the model, these glasses allow for peripheral vision correction and have an adjustable viewing range.

It may sound like a futuristic concept, but many major retailers carry these products, and people are taking notice and purchasing them for themselves and as gifts. Video goggles may just replace the way that the family watches TV, together, but separately at the same time.

Why is there no FM Radio For iPhone

iPhones have great amount of features and have tools that are way ahead of standard cell phone. Add this together with its ease of use and great styling, you have a winner. It also comes with the best of Web 2.0 display and toys.

In fact, the iPhone has many things going for it, but does it have FM radio for iPhone? But for some reason when apple were adding the digital camera, web access to Google maps and all the other cool features, the FM radio was not on the list

"Old school?"

Actually the main reason why there is no FM radio for iPhone is that today, the interest in FM radio is less than in the past. The Internet and TV are dominating the market for eyeballs. This is especially true when you consider the target market Apple is aiming at - young people with disposable income.

After all, it is not the fifties or sixties when radio was central to entertainment and information distribution. Now days the Internet is the first step for most people looking to find out information.

Another possible reason why there is no FM radio for iPhone is that the radio is not a very personable device. It can be a disruptive influence in our lives rather an asset. Of course, if the iPhone had been around when the Sony walkman was invented, chances are that there would certainly have been a radio.

In fact, the Sony walkman had become popular with the public before a radio was added to it. This lack of a radio in the original Walkman can be seen as a reason why manufacturers have not included FM radio for iPhone.

Still, you might wonder if the iPhone can have Internet connectivity, then why is there no FM radio? After all, the iPhone is multi-media should have indeed been included. The answer to this may lie in the fact that there is always iTunes to listen to and thus there is really no need.

However, it is only Apple that can best answer that question. The reasons for omitting this feature would no doubt be due to practicality or maybe lack of need. However, consumers have yet to be informed by Apple regarding and so we can only guess as to the reason why.

GPS Tracking Technology Used To Keep Kids In School

Who would have thought school truancy would play a part in the high tech world of gadgets? The Dallas Independent School District (Dallas ISD), that's who. Faced with a dropout rate ranking them seventh among large school districts, according to America's Promise Alliance, and a truancy rate of 15%, the school was not only losing students but also the funds connected with school attendance. It was clear they needed something to stem the leakage. The solution fell into the lap of Bryan Adams High School which is currently using GPS tracking devices in a pilot program to retain their student population.

The GPS tracking devices worn by students are similar to those used by law enforcement keeping tabs on individuals under house arrest, rather than a simpler less obvious GPS tracking watch. Six students, out of the 300 sent to truancy court, from Bryan Adams were chosen to participate in the program. The price tag for the digital age truancy program? $26,000. The investment covers a case worker whose duties include tracking the students, assisting them in their daily activities, as well as providing assistance to families.

The program is proving more cost effective for the state compared to the alternative of detaining repeat truancy offenders in a juvenile detention facility. The program also benefits students by providing a measure of structure, which will translate to a greater ability to become a functioning member of society — like showing up for work on time. This structure is priceless for many of the students enrolled in the program because it is hard for them to create this structure otherwise.

Other than making students show up for class and train for adulthood, the GPS program for truant students hits more personal issues. Most truant students are dealing with more than just running late for class. Issues facing the majority of truant students run the gamut from drugs or alcohol, gang involvement, issues in their family life, or any mix of the above. In the past year, the GPS system helped find a student in the pilot program on the verge of a drug overdose. The program also led case workers to a student that had ditched school and was contemplating suicide. In both situations, a GPS tracking device helped case workers find and assist these students.

Sounds like a great system? Not everyone thinks so. One Texas law maker, as summarized in the New York Times, dislikes the idea since “ankle cuffs used in an earlier version were reminiscent of slave chains.” No one wants to make these students out to be slaves, just to help them. The comment could stem off of the fact that the majority of Bryan Adams High School is non-Caucasian. The high school's representation includes 53% Hispanic American, 32% African American, in addition 62% of the student population is grouped as economically disadvantaged.

In any case it seems Dallas ISD and Bryan Adams High school are trying to do a good thing. They're just using the greatest and latest technology to do so. Who doesn't want help students maintain attendance, graduate high school, and attain prime jobs? Of course, the utilization of GPS technology in improving the systems in place, such as student truancy, needs to be further tested in a variety of situations if we are to fully develop and utilize this powerful technology.
