New Technology TV

Home entertainment enthusiasts have been anticipating 3D technology for decades. This shouldn't be surprising. After all, once 2D video became standard many people though that the next logical innovation would be 3D video. Comcast has been one of the leaders in this technology. While this 3D technology makes sense logically, it has been fare more difficult to actually implement. There are a number of different technical reasons for this, but it really comes down to the fact that our depth perception- the aspect of human vision that allows us to see in three dimensions instead of only two- is based on the fact that our eyes are a couple of inches apart, thus allowing us to see slightly different views of the same object simultaneously. The human brain interprets these different views into a three dimensional image of the physical object in front of us. Because of this, any video technology that displays things in three dimensions has to project at least two views of the same object at the same time and do so in such a way that each eye of anyone looking at the image will see different views. This can become extremely complicated!

There are a number of different ways that the creators of entertainment technologies have produced 3D images. The one that most of us are familiar with is the technology used in theaters that requires viewers to wear special glasses with polarized lenses. The polarization of the lenses filters that light in such a way as to let different views into each eye. This technology has actually been around since the middle of the twentieth century and is extremely effective though it had a lapse in popularity because of the side effect of headaches among viewers. More recently, this 3D technology has experienced a renewal in popularity thanks to the ability of digital technology to eliminate the headaches.

It's also possible to design an HDTV screen that will project a three dimensional view of an image without the use of glasses. There are several general techniques that can be used to do this, and the lack of agreement in standards has held up the development of this technology.

A third way of creating a three dimensional image is holography. Holography uses lasers to produce what looks like a free standing image in empty space and is able to dispense with a screen in the normal sense. Holography does require some sort of projector though. This is the technique that comes up most often in science fiction, but would be the most difficult to execute using current technology.

There are some things that we can be sure about when it comes to 3D TV technology. One is that we've just begun to scratch the surface of what this technology can do. For example, 3D technology could vastly enhance the promise of virtual reality in the sense that virtual worlds such as Second Life could be that much more real. Another is that we'll see 3D technology play a bigger role in marketing. In fact, with the help of short range radio broadcasts, it may be possible for billboards to project their advertisements into your car!

In any case, while 3D TV technology may be slow to take hold, it will definitely be here to stay once it does. Get ready for all the new innovations by having Comcast television and internet service today!

In this economic climate many people are trying to rein in their spending. One strategy that has been tossed around here and there is to cancel the TV subscription and watch video on the Internet. While this is certainly possible, there are some things that you should know before you go ahead and make such a move.

First of all, it's a good idea to understand how the Internet transmits TV. Like every other kind of data that's transmitted over the Internet, video is sent in packets of data instead of a steady stream of data. Each packet that enters a router on the Internet must wait its turn to be transmitted and some of them are “dropped” or eliminated in the event that there are too many of them being transmitted through a specific route all at once. This means that online video can be choppy- especially when there are a lot of people using the Internet all at once. Also, if there are a lot of people trying to access the same video that you're watching, or even other videos stored on the same server, you'll experience choppiness or have long periods of time when you have to wait for the buffer to fill up before you can watch the video without choppiness. Fortunately some of these problems can be alleviated by having a faster Internet connection such as Comcast, but considering that normal video needs less than 1 Mbps on the receiving end to run correctly, there are times when more bandwidth won't really help anything.

Another thing to consider is that you might not necessarily have the computer equipment available to allow you to watch TV through your computer in a way that will be satisfying to you. For example, if you have a laptop, the screen is likely smaller than will be convenient for you. You'll have to position it very close to you and even if you're okay with that, it will probably be difficult to watch with more than one other person. Even if you have a good sized LCD screen, you should consider the fact that such a screen is probably located on your desk instead of in your home entertainment center. While there are ways around this problem- such as by taking advantage of a Sling media device, an Apple TV, or installing a computer in your home entertainment center; they are likely to be expensive initially and will offset the ability of this change to save you money.

Of course if you're willing to deal with some of the inconveniences of watching TV over the Internet, it can be a good way to get the entertainment that you want while saving you money. The fact of the matter is that when you're watching TV shows online you'll be spending less time watching commercials because in most cases only one commercial is run during a commercial break. On top of that, it could be argued that TV service is more expendable for many of us than Internet service. After all, high speed Internet that you can get with
Comcast is a virtual necessity for work and school, whereas with the help of Internet TV, you can really make do without a dedicated TV serice.
In any case, it's important to take these things into account before giving up your TV service.
