A lot of people are currently very confused as to which format to go for, HD-DVD or Blue Ray, as the current format war continues. Generally members of the public do not know what strengths, weaknesses and unique selling points there are for each. To understand what blue ray is and be better informed as to your choice you need to know what technology actually makes it work, the film studios that are endorsing the format and some over points which we will cover later on. An upgrade could be an expensive wrong move if you do not go into it with your eyes open.
Blue Laser or Red Laser? - That Is The Question
If somebody stopped you in the street and asked "What is Blue ray?" would you be able to answer them? Probably not. The answer to the question actually lies within the question. Generally it is not possible to define a difference between a Blue ray disc and a DVD disc as the look the same, are the same size and shape.Blue ray is called Blue ray because of the fact that it uses a blue (violet) laser to read and record data of all kinds including the likes of video and audio. Smaller and finer technological processes are used which pushes up the initial costs associated with Blue Ray compared to DVD's. We will however see the costs come down quite rapidly over the years to come as the process becomes more common and the technology easier to produce.
Comparison Example Of What Blue Ray Is
Compare it to a standard DVD as you would compare a calculator to a pc. Both of these can perform all sorts of mathematical equations and much but the pc can perform many times faster than a calculator can as it is infinitely more powerful. Using that example with Blue ray, a DVD and a Blue ray disc can perform the same type of operation but Blue ray is capable of outperforming a DVD, doing a much better job in playing better audio and video.
What Movies Can You Watch
Whilst educating yourself on exactly what Blue ray is, it should be borne in mind what films you will be able to purchase in your chosen format. Some of the popular films you can buy are only available on HD-DVD, whilst alot of the others can be obtained on Blue ray. As at January 2008, if you use a Blue ray player you won't be able to watch the 2007 box office hit Transformers. On the other hand the latest Bond sensation, Casino Royale, will only be available on Blue ray (that said, all of the movies are still released on standard DVD, these comparisons are for next generation video format). You can of course obtain a hybrid player which will obviously play both Blue Ray and HD-DVD but film releases are tending to favor one format or the other.
In conclusion you should at least now have a better understanding of what Blue ray is to enable you to make a more informed decision when you ultimately decide which format to upgrade to.
