You know most of the time you find yourself downloading all kinds of stuff, including mp4s, mp3s and the like, but what about the technical end of it. What is MP4?

Mp4s or rather the term mpeg-4 was developed by ISO (International Organization for Standardization). It is a format specific for multimedia, the most common uses are for digital audio and video, and it is a certain type of container that holds all this information. It can contain other data as well such as subtitles and still images. You should also note that mpeg-4 is identical to QuickTime MOV format. In fact any kind of data can be inserted into MP4.

MP4 is getting more and more popular. In fact, it is now very popular to people who use the latest iPod players and PSP owners. This type of file compression is now providing a way to store dvd quality movies at a very small size. This type of file compression is known as the MPEG4 format.

Because most users may get confused at the initial concept of what MP4 is, it is what is in the MP4 that is even more confusing since the extension has been used primarily for music tunes and not movies. Therefore, what is stored in an MP4 is more than you can imagine for the most part. In addition, those other extensions have been used for MP4s, (which is audio from an iTunes store), to m4a (which includes such things as chapter markers, images, and hyperlinks). In addition, of course m4b (which has the ability to work with IPODs, where m4a files cannot. So most of the time when you find a file with the extension of mp4 or m4v, then they have both the audio and video aspects.

Let us not forget of course that they can contain codecs as well. Therefore, as you can see there is much to learn about what MP4 is, so let's summarize;

MP4 Can include and contain audio, video and also still images (like pictures), and all kinds of other data, making it a diverse file to use.

MP4 can contain other types of competing technology e.g. ogg, vob, ratdvd, divx media format, Matroska (mkv) and others to name a few.

In addition, how about some of the compatible hardware or software that mp4s can work with? Such as in software: Amarok, Banshee music player, 3ivx, foobar2000, GOM player, iTunes, media player classic, QuickTime player, Realplayer, VLC media player, and so forth, as for hardware: Kiss 1600, apple iPod, PSP (playstation portable), Playstation 3, xbox 360, Nokia.

Therefore, to answer the question what MP4 is, well, it is technology at its best!

Indeed, the MP4 technology can now make entertainment much more convenient than ever before. So, next time you think of downloading your favorite movies to your computer to transfer to your portable multimedia device, try thinking of MP4. just make sure that your multimedia devices are capable of reading the MP4 format.

Make sure you know what you need from a digital camera before you buy!

You might be thinking about making the leap from a regular camera to a digital one but are unsure of what you need. This article should be able to clear up some of the finer points to help you make the best possible purchase for your money and needs.

First, when looking at digital cameras, think about what you really want out of it. Do you want to save time and money on developing costs? You will definitely benefit with just about any digital camera on the market here.

Second, you may or may not know that digital cameras are the best way to go for most any household. The range of features available make a digital camera very cost effective and more than likely you can find the exact type of camera for your needs.

If you are not the best photographer and often end up getting back your developed pictures to find out that you have cut the head off your Aunt Mary, then relax, the digital camera is here to help. For this type of photographer, you will want a camera with a wide screen on the back. This way you see what you are taking a picture of and the best part about it is that you can see the picture seconds later instead of waiting until they are developed, which saves time and money.

If you were looking to print out your pictures to hang on the wall or send to relatives then you would want a digital camera with a high resolution. This is especially important if you tend to have your pictures enlarged.

On the other hand, if you tend to share picture by viewing them on your computer or only on the web, then you really don’t need to be concerned with buying a high resolution camera.

The Macro Feature would be something to look for in a digital camera if you tend to take close up pictures or love to shoot pictures of bugs, coins, or very small objects.

Another consideration is if you are going to be taking pictures of high speed objects or at sporting events. Then you would want to look for a fast burst rate. In addition if you are taking many pictures at night then you would be looking for ISO equivalents or sensitivity settings.

There are many factors in buying a digital camera and like so many events that take place in life, there seems to be a digital camera to match. Read up on the camera that you are considering buying before making the purchase. You just might save yourself some headaches by doing a little research before you buy.

Man has always speculated about what lies beyond his immediate circle of knowledge. Many a journey has been taken and many a new land has been discovered all because of mans curiosity. The uncertainties faced and risks taken in the name of adventures and travel has claimed many lives. Navigation and maps are vital to these activities.

Luckily for us, we live in an age of new and innovative ways for technology to help us and one of them is the GPS system.

global Positioning system (GPS) is a worldwide navigation system formed from a constellation of 24 satellites and the associated ground stations. There can be more than 24 operational satellites; new ones are launched periodically to replace older satellites.

Each satellite orbits continually about the same ground track (as the earth turns beneath them) once per day, at an altitude calculated to ensure the satellite repeats the same track over all points approximately each 24 hours (actually 4 minutes earlier each day).

There are six orbital planes, equally spaced (60 degrees apart), and inclined at about fifty-five degrees with respect to the equatorial plan. The GPS system uses man-made stars as reference points to parse accurate positions to within meters.

The GPS system in its entirety is comprised of a network of satellites, signals, support personnel, ground based hardware and software, which make possible the establishment of ones precise location on the Earths surface. The global Positioning system is funded by and overseen by the U. S. Department of Defense (DOD). While there are many thousands of civil users of GPS world-wide, the system was designed for and is operated by the U. S. military.

The accuracy of location measurements using the global positioning system depends on the GPS receiver. high-end, survey-grade GPS receivers can determine locations precise to within centimeters. but even low-end, handheld consumer receivers, can be accurate to within fifteen meters. GPS receivers have been miniaturized to just a few integrated circuits and so are becoming economical and readily available.

The first commercial global positioning system units were precise for only about 100 meters because the military scrambled the signal--a program called Selective Availability. In the year 2000, the u.s. government removed Selective Availability, improving the accuracy of even basic handheld units to within fifteen meters. Today, with additional information from ground based correction services such as WAAS WAAS (Wide area Augmentation Service) or u.s. Coast Guard differential GPS beacons, accuracy can be improved even further.
