The advent of Blu Ray is certainly upon us, it is slowly creeping into people’s collections as the high definition video format of choice. Advocates are quick to assert that this new format is not only a better way to watch movies, but a way for collectors to protect their collections from future development; the term being bandied about is ‘future proofing’. But how does the Blu Ray format work? What makes it different from regular DVD?

Blu Ray has been developed with the cooperation of some of the world’s most recognisable technology companies, for instance, Sony, Samsung and Sharp have all been instrumental in this development and all three are likely to push the widespread use of Blu Ray in the future. The disc is physically different to regular DVDs in a number of ways. The reading formulation of the device is unique, using a blue-violet reading system that gives the format its name.

The result of this system is a shorter reading frequency and for the sake of not getting too technical, means that the shorter the wavelength, the greater the capacity of the disc. Whether the Blu Ray disc is single or double layered relates to a storage capacity of around twenty five and fifty gigabytes respectively.

The launch of Blu Ray occurred in 2006 and marked a watershed in the design and development of high definition viewing. Its ingress into the market has been slow at first but this situation is rapidly improving. In the early stages their was a considerable battle between the Blu Ray and HD DVD formats that resembled the eighties battles between Beta Max and VHS.

Blu Ray eventually won this battle due to a wide variety of backers such as movie studious and retailers. These movie studios include giants such as Warner Brothers, Disney and Buena Vista whilst the retailers that jumped aboard consisted of internet marketplaces such as Amazon. With such a large backing it was almost inevitable the Blu Ray would win out, although the competition from Toshiba’s HD DVD was considerable at times.

Since the end of this ‘format war’ Blu Ray has made serious advances in terms of sales. A recent release, Twentieth Century Fox’s Hitman actually experienced a record fourteen percent of sales in the Blu Ray format. While this is still a relatively small number in terms of total percentage, it shows that as the number of players in the marketplace increases, the exposure of this format will also become more widespread.

Critics are quick to espouse that the advancement of BD is limited due to price; the research however tells a different story, one report has stated that while the ingresses into the entertainment market are slow, if compared to DVD in its early years Blu Ray is actually doing better and experiencing a greater level of exposure.

What does the future hold for Blu Ray however? Clearly those involved in its production will be hoping for yet more exposure into the entertainment medium although technologically it is expected that while single and duel layered discs are now on the market; the coming years are likely to bring a quad layered disc holding one hundred gigabytes of data. Even so, development is ongoing, with some companies striving to produce a sextuple layered disc capable of holding almost two hundred gigabytes. In addition the future is likely to bring recordable discs for the recording of HD television programmes and schedules.

With such a strong corporate backing it is unsurprising that Blu Ray has succeeded in winning the format war. Movie buffs now regard BD to be the best and most preferable viewing format whilst also considering it a great way to future proof a collection. Whatever the critics say the development of Blu Ray technology is certain to continue.

Technology specialist Thomas Pretty looks at the development of Blu Ray discs and systems and how it is now possible to have HD movies at home.

Prepaid cell phones are a great option for people who are looking to avoid the hassles involved with signing a contract and the costly expenses that come with overage charges. These days, you can find a lot of prepaid cell phone plans that can rival the service you would get with a traditional service. Many of the large companies who have the typical two-year contract model offer prepaid or pay as you go methods of mobile phone use.

As a result, there is a lot of choice out there. This is good on the one hand, because it means there is competition and a lot of different companies to choose from, but it also makes it difficult to narrow it down to one company and actually make a choice. You also want to try to find the best deal and that involves comparing postpaid and prepaid cell phone offers to each other to find the best value for your precious money.

The last thing you want to do is pay too much and not use all the cellular minutes you pay for. But you also want to avoid paying too little, so you run out of minutes too soon or have to pay expensive overage minute charges.

Most of the well-known cell phone networks offer post paid as well as prepaid plans. It is worth your while to look at the costs of both, as you keep in mind how many minutes come with each plan. Virgin Mobile offers a pay as you go plan that includes the feature of roll-over minutes, which means you get to carry unused minutes over into the next month and use them. Typically, this can be a welcome feature in a post paid cell phone plan, but as an incentive, often you see a company offering this same feature in a prepaid plan. So keep your eyes open for deals like this, where you can get post paid features in a prepaid plan.

Keep in mind that some prepaid providers charge a daily fee for use of their phone minutes. An example is Verizon. So while their prepaid plans may seem like they’re saving you money, you must remember that you will be paying an additional charge for each day you use the phone. In Verizon’s case you pay a dollar a day for use of the phone. Just factor that into your overall calculations and see if it still makes sense and saves you money.

You need to consider numerous factors as you search for the cheapest option for your mobile communications. Look at as many companies as possible and compare and contrast the benefits of each plan. One other thing you should know is that most prepaid cell phone providers do not provide a free cell phone. It is typical for a company to offer a free phone when you upgrade your plan or sign a contract extension. Since there is no contract involved in a prepaid cell phone agreement, that incentive is gone.

Check the prices of the phones that work with each offer. Often you will be able to find a good deal on a cell phone on eBay or Craigslist. It just takes a little time and research. The beauty of the prepaid model is you can screw up and sign up with a service you end up not liking but you don’t have to stay with them because you never signed a contract. Thus, there is no cancellation fee, which can be a total rip-off.

The MP3 or digital audio player has been with us for some time and can now be considered the most convenient and portable method of carrying music around with us. Before the development of the MP3 file format and subsequently a player for this format the most common form of digital music device was the personal CD player, however this had serious limitations, particularly in terms of size where it was restricted to the proportions of the CD.

Attempts were made to introduce a smaller device, taking the form of the Mini Disc player although its use was limited and it did not become as popular as the CD. Today, there is an MP3 player in nearly every home in the modern world; in addition they have been incorporated into mobile phones for ultimate convenience. But what is the history of this little device?

The first digital audio player or DAP was produced as recently as 1997 by a company named Sae Han Information Systems, it was marketed as the MPMan by this South Korean company throughout 1998. It utilised a flash based memory but could only hold a paltry sixteen megabytes of data. The size restrictions of this inaugural device led to the development of a player with a hard drive. Compaq conducted the initial foray and with the cooperation of HanGo Electronics released the PJB-100 (Personal Jukebox), a device that could hold almost 4.8 GB of date, equating to over a thousand songs.

It was from this point onwards that a device was released that would not only revolutionise the design of MP3 players but design in other fields. This was the first generation of Apple’s iPod. In the beginning it was the Macintosh fraternity who used the device but thanks to a simplistic interface and minimalistic styling it soon gained acclaim and grew in popularity. The second generation iPod was a revelation and was now compatible with Microsoft PCs and hence users now had more freedom to transfer their MP3 tracks. Many other manufacturers also got into the act and released players that were similar in function, if not in form to the iPod.

Fundamentally there are two main types of MP3 players on the market today, these are flash and hard-drive based. Flash players have no mechanical parts an instead hold the musical information on a flash memory that is either built into the device or is on a memory card. While in the early years of DAPs flash devices were seen as the more restricted of the two variants, modem technological advancements however have meant that flash players can hold up to around 32 GB. The benefits of flash MP3 players is that they have no moving parts and are hence less susceptible to failure as well as using less power.

Hard drive MP3 players differ from flash variants in the way that they have a mechanical drive that stores the data. The HDD is read by the device to access the music and because the data is stored mechanically they are able to hold larger amounts of data. In some cases hard drive players can hold as much as 250 GB of data; the benefit is that the user is able to carry their entire music collection wherever they go with ease.

Today the MP3 player is one of the most noticeable forms of technology that we see everyday. On the streets, on the plane, train or bus there is almost guaranteed to be someone listening to a DAP, by reducing the size of the personal music player through advances in data retention technology it has been possible to bring portable music to the masses.

Technology expert Thomas Pretty studies the development and history of the MP3 player and how it has revolutionised the way people listen to music.

When most of us think of GPS tracking watches one of two images pop into our mind. The first is that of a child locator that fits on the wrist of child. The second is that of a watch on the arm of an athlete (usually a long distance runner). Both of these watches are essentially the same, but used in very different ways.

The first watch is used almost entirely to track and keep tabs on a child. A concerned parent will outfit their child with a GPS tracking watch just in case the worst were to happen to their child. They feel that it gives them the peace of mind that they need to send their child off to school, or to the park, or to the mall. They often feel that this locating device is exactly what they will want if an abduction or kidnapping were to occur.

Normally watches like this help the parent take back some power that they felt has been stolen from them in our society of parental isolation. They cannot trust their neighbors to keep an eye on their children with them because we are so distanced from those that live around us, especially in suburbia. At a mall with a thousand people in it, your child could become entirely lost and could not see a single familiar face. People might walk by your child without even know that they are lost or in need of assistance.

A child locator watch is exactly what parents need in this circumstance. If they have an internet enabled phone, they can check their provider’s website and find the location of their child to within a few meters. Or, if the watch has a two way communication feature, the parent can call the child’s watch and communicate with their child - letting them know that everything is going to be okay and that they don’t need to worry. They then can get the information from the child that they need to locate them, ending the issue and empowering the parent.

Fitness GPS tracking watches work a little differently than a child GPS tracking watch. Most fitness watches are simply data loggers, gathering and storing information on the watch’s computer to be analyized at a later time. All you need to do with one of these watches is put it on your wrist, strap on your heart monitor (if you model supports one), turn your watch on, and head out on your run.

These watches will do all the work for you, recording your speed, elevation, and heart rate for you to see. They even will record your actual location so that you can integrate it with some mapping software back on your PC. Sometimes this software comes with your watch and sometimes you can use free software like Google Earth, it simply depends on the make and model of your watch.

These watches are good for fitness applications and while they can be used for other things (like analyzing you heart rate when you drive) they are pretty much only good for that.

As you can see, both types of GPS tracking watches provide the same essential GPS tracking function but do so for different purposes. A child GPS tracking watch is logs GPS information and then sends it out for the parent to see. A fitness GPS tracking watch, on the other hand, simply logs information for you to download later. Both have their place in, and both are used differently.

Getting the most out of your gps tracking watch is very important. Need help with finding the right one for your needs? Check out our kids GPS information to help you make your decision.

During the last thirty years, the conference calling services have transformed from being a tool used primarily by large businesses to being something that is widely used by businesses of any size, as well as by private groups and even families. Conference calling has become so common these days that almost all of the new models of cell phones have a built in function that supports small conference calls.

Gone are the days when you had to have some massive, specialized and expensive equipment in order to host conference calls. These days, there is a good selection of low cost teleconferencing equipment that is affordable for virtually any company. Not only that, but there are even small groups and organizations, and even families, who can easily justify the small cost of teleconferencing equipment in order to make it easier for everyone in the group to stay in touch.

There are a number of different conference call equipment systems available on the market today. The conference call equipment that can handle hundreds of people calling into the system can cost thousands of dollars.

Yet, there are also smaller models designed to sit on a conference table, allowing a number of people in the room to hear and talk at the same time. This small teleconferencing equipment can be purchased for less than $100.

No matter what the cost, it does not take long to justify the expense because most of the time conference calls are replacing off-site meetings, which might be across the country or even across the ocean. These days, a teleconference is a very viable alternative to travel and it can save a company thousands of dollars just in a single month, if they are accustomed to sending many employees traveling around the globe on a regular basis.

In addition to buying equipment to host your own teleconference, there are also many teleconferencing services provided by companies that invest tens of thousands of dollars in the equipment. These teleconference services then allow companies to essentially rent their equipment and typically charge a fee based on how long the teleconference will last and how many people will be calling in.

Some of these services provide an 800 number so that the participants can call in without incurring long distance charges. In this instance, the company booking the service pays a “per minute” fee for each person who calls in on the 800 line.

This arrangement is a very good way to conduct conference calls that are held in order to do a sales presentation to prospective clients. Many times, clients will simply not call in to listen to a presentation if they have to pay for the long distance call. Having them call a toll-free 800 number makes a better impression and sends a message to the client about how they will be treated in the long run when dealing with the company.

Many small companies and organizations like to use the conference calling services that are completely free. This allows those in a group to call into a free teleconferencing number at a time that has been reserved by the person organizing the call. There are no fees or charges for using these free services, but in most cases people need to call into a phone number that would incur long distance charges.
