Are you ready for 3-D TV?

Tuesday, December 23rd, 2008

If you want to know when three dimensional programming would be ultimately functional on television, you need not wait any longer. Answer to this query is ‘now’. However, do not expect it at your door step right now.

On 4th of December, reality went on to shoot the 1st NFL game, which was to get broadcasted in three dimensions. They also moved further with production of U2 concert in 3-D, distributed by ‘National Geographic’, which performed the task of playing in cinemas all over the country.

The good news is that it’s not tough to have created three dimensional programming for television any more. This procedure is, in fact, difficult for cinemas. However, setting of 3D standards is facing loads of technical obstacles at this moment. The situation is so critical that there isn’t any agreed-upon method for transmitting the image ‘over the air’ or through satellite. Besides, there isn’t any prescribed method to decode the image after it reaches television, and to create a three-dimensional effect on television.

The credit of developing a three dimensional camera goes to 3ality. To be precise, 2 cameras are tied to one another. ‘Depth Effect’ differs on the basis of the distance between the two cameras, and the angle between each lens and its partner. By having manipulated the relative positions of the camera, foreground can be extended beyond screen or receded behind it.

If you have found watching a 3-dimensional movie difficult, the main reason isn’t the ‘technique’ used, but lack of perfection in terms of application. 3ality’s sister-concerned in Germany is in to development of a lot of ‘software techniques’ which permit one of the post-production operators to rectify for three-dimensional cameras and mismatched frames that had been placed far apart for having created an image that’s comfortable to see.

If you expect 3-D to resemble reality, you don’t need to hold the breath. While there isn’t any question of the effect creating depth, scenes having ‘planes of depth’ are often created. However, there is little depth inside an object. Hence, 2 people might appear at dissimilar distances, but every figure appears of being flat.

To combat this problem, producers of three dimensions frequently keep camera in motion; by continuously changing shadows and angles. The brain goes on to perceive objects with greater depth. This technique has been used by 3ality in production of U2. Next year would be full of surprises for the tech-savvy people. NBC would be airing the shows, i.e. Chuck’s 3-D episode. Capabilities of 3D would be seen then.

The above-mentioned show, would, however, not show 3ality’s finest work, as Chuck would be shot by making use of anaglyph three-dimensional method. As with three dimensional comic books of the 60s, viewers would be required to put on special glasses with cyan and red filters for seeing the three-dimensional effect. The ‘anaglyph technique’, unlike polarizing three-dimensional system, can’t go with accurate reproduction of colors. This is the reason behind it being not taken positively with regards to future three-dimensional television programming.

5 Simple Tips to Speed Up Your PC

Tuesday, November 25th, 2008

Almost everyone must have experienced the excitement of bringing over a new computer. However most of the people have also experienced very soon that it takes twice as long for the computer to start and additionally it also starts showing error messages and slowly you notice that your computer is has become considerably slow. The reason for slowdown of your computer performance can be due to several reasons. Therefore the first step to resolve these issues is to find out the cause for these issues. Some most frequent and common causes for low performance are


  • Corrupt registry or poor maintenance
  • Fragmentation, capacity issues or hard drive errors
  • Malicious processor functioning (malware, spyware, viruses)
  • Too many processes or programs running


It can be frustrating to deal with slow performing computers and many also end up in spending a lot of money to repair it. However there are a few steps that you can take to not just stop these issues but also enhance the overall performance of your computer.


Run System Maintenance Programs Regularly

This program will check the hard drive for any fragmentation or errors and will remove all the unused files. This can actually go very deep in preventing decreased computer performance when done regularly. These fragmentations means the way files are located on the hard drive and what you see as a single file is actually scattered in different drives. They are totally invisible to you and can reduce your computer performance. Defragement will basically relocate the files in a more effective and precise way. The tool to do this actually comes pre-installed on the computer but there are also more systematic maintenance programs available.  


Check for Malware, Spyware and Viruses Regularly

These viruses can actually cause havoc in any computer and they drastically decrease computer performance. Finding and deleting these malicious software pieces is very important in order to increase the performance of your computer. You can do this through several antisyware or antivirus programs available.


Check for Registry Errors

The registry basically stores all the important settings and information of the computer. As you use the computer and add or remove programs these problems start increasing in the registry. As this registry is essential for programs to run you should regularly maintain or clean your registry through the registry cleaning software available.


Simplify Computer Start-Up

Although you actively use a single program there are several programs running in the background without you knowing. These programs actually install themselves and even start-up automatically with you turn-on the computer. These programs can actually increase the start-up time and so decrease your computer speed. Some ways to resolve these issues is to remove all the unused programs and secondly implement start-up shields. This start-up shield lets you find and control programs running on start-up.


Check RAM

Hardware problems can also cause computer slowdown. The contemporary operating system available is very sophisticated and will require more RAM to run smoothly. Therefore if you have less RAM then it is very easy to upgrade your computer’s RAM using RAM chips and is also very inexpensive.
