The first success in the creation of a digital video was reported back in the 70s and 80s when with a special effect unit and some time base connectors, an analog video input was digitized. The outcome of such experiments was the improvement of the video quality for manipulation, effects and signal. Bosch also created digital video equipments in the 70s but they remained lab research only until 1986 when the first digital video was created with Sony D-1.

In the first forms of digital video, the analog source remained essential because it served for the digitized encoding that could be read by computers. Little by little, television transmissions adopted the digital video standard when passing from the analog to the digital signal. Soon, the appearance of the non-linear editing systems would mark the evolution of electronics for good. High definition television would not be possible without it.

At present, almost every family has at least one digital video camera, not to mention that the technology is available with all the communications devices we use today. Only the older phone models are camera-less. The more popular concept of camcorder (a device that combines the recorder and the camera) is winning the market as our society depends on the quick quality access to information more than ever. A digital video can be stored and copied without any degradation of the information; after editing, the clarity of the image is the same as at the moment when it was filmed.

Digital video applications are more numerous than just the private use with mobile phones; Internet communications and conferencing systems are the best examples here. The editing process for the applications has been simplified to a very large extent and the Internet abounds in programs, tools and softwares that are provided for free download. Windows Media and MPEG2 are the most common of Internet applications that perform digital video editing.

One can hardly express the full number of applications and the usage extent of digital video technology nowadays. From home applications and corporate business, digital technology has become not only relevant but characteristic of our society. And we can expect to use it in even more evolved forms over the coming decades. Digital video technology can still surprise us!

There is an affluence of professional and amateurish digital videos on the Internet. Whether interested in the idea of private journalism or just attempting to make something of the filmed materials, people keep uploading their digital videos on the world wide web. And this private film trend is intensely encouraged by web sites like YouTube. Any modern mobile phone comes with an incorporated camera; no wonder we get so many digital videos.

Almost all the materials broadcast on television are digital videos because this technology is much more efficient in rendering the quality of both image and sound. Digital videos can be captured with more or less professional equipment, yet, the good part is that they can be improved by editing. The editing part is conducted by means of software tools that allow the transfer and the processing of digitized data onto memory disks.

Digital videos are not difficult to shoot in the amateurish mode as they require no technical skills or knowledge on the part of the user. The electronics of the camera can perform all the tasks automatically. However, professional cameras are usually operated manually in order to achieve high performance in image capturing. Pros really know what they’re doing. We could also say that the combined automatic-manual model is even more popular, because very complex video digital equipments are sometimes difficult to operate.

Thus, some will shoot digital videos to have great memories while others make a profession out of videography. All important events like weddings, child birth, ceremonies, baptisms and corporate receptions require a videography service. Digital videos will later remind people of the event allowing them to re-live the beauty of some special moments. Many videographers also advertise online, which makes them a lot easier to contact.

If you are interested in learning more about shooting digital videos, we recommend either professional training or self-learning methods on the basis of educational materials. No skill is required for taking some basic digital videos with the phone camera, yet, society needs much more than that. Higher quality comes with better equipment, knowledge on shooting angle, exposure and the rest of the professional secrets.

There are barely any electronics items sold these days without the word digital appearing somewhere on the packaging. Great change has been made in the last twenty years regarding digital technology, especially the technologies that relate to home theaters. In days past, a home theater system was thought to be exceptional if you had no more than a big television and rudimentary surround sound. But, with the coming of superior digital technologies, household theaters have become both more sophisticated and more expensive.

Especially in the case of digital LCD projectors, there have been great changes of late. Starting out, the size and price tag alone of projectors made them ludicrous for a possible home theater, particularly given their minimum $50,000 price tag. The vast majority of home theater users weren’t actually in homes.  Initially, it was only universities and major businesses that could afford such costs. A lot has changed in this respect.  Now a days, smaller and less expensive projectors can be bought from any large vendor of electronics. 

The first decision that must be made is where, precisely, you will find room for your DLP projector. The projector you buy must fit the size of the area while also making a suitably sized picture on the screen. You also must determine if you will mount the projector on a table or from the upper surface.

Undoubtedly, the factor that varies the most from model to model is luminosity. In a completely dark room, you can easily get away with a projector with about 1000 lumen. Whereas, if you are in a room with any kind of extra light, you will need greater than 1500 lumen. If you get a projector with too few, you will have difficulties seeing the picture.

The clarity of the picture is usually referred to as resolution.  Many different resolutions exist for home projectors. The worst resolution out right now is called SVGA which sits at 800×600. With a smaller picture size, this resolution is passable, but better resolutions are without a doubt worth the additional money placed on them. Other resolutions include XGA (1024×768), WXGA (1280×768), SXGA (1400X1050), 720P (1280X720), 1080P (1920X1080) AND 1080I. 1080p is the current best when it comes to full HD and produces fantastic picture. For several years, 1080 1080 is a citation to the number of lines of resolution.

As opposed to years past, when household theater DLP projectors would cost you a small fortune, currently there are many cheap projectors available. In some cases, you can snag a projector that elevates your home theater experience to a new level for a maximum of $1500. As soon as you have decided upon your home theater projector, there is still much more work to be completed. To create the perfect home theater experience, you will need a professional audio system and, of course, the most comfortable of comfortable chairs.
