The history of the modern digital video started back in the 70s and 80s when the analog video imput was digitized by means of time base connectors and digital video effects units. The outcome of such experiments was the improvement of the video quality for manipulation, effects and signal. More digital video equipments were created in the Bosch research labs in the 70s but the commercial introduction took longer, with the first digital video available with Sony D-1 in 1986.

The first types of digital video formats depended on the use of an analog source that served as the starting point for the digitized encoding in computer-readable patterns. Little by little, the passage from analog to digital signal became predominant with television transmissions adopting the digital video standards. Soon, the appearance of the non-linear editing systems would mark the evolution of electronics for good. This progress contributed significantly to the introduction of the high definition television.

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. There is hardly any mobile phone model that does not incorporate a digital video camera. 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.

Besides the combined use with mobile phones, digital video has lots of applications with video conferencing systems as well as with communications on the Internet. 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. The most common format for editing a digital video with Internet applications is Windows Media while MPEG2 is exclusively used for DVDs.

It is impossible to exhaust the number of applications and the constant extent of digital video in day to day life. From corporate business use to home applications, 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. There is more in stock with digital video than we may know!

Digital Video Software

A digital video software represents the basic platform for the operation of all tools that perform the editing of materials captured and stored digitally. Every digital video software may come with several versions, but the product descriptions and the information on the features that have been added or improved are conclusive for the operator. The demand for digital video software tools has increased thanks to the wider use of camcorders. Travelers and parents are among the predominant users, yet, not all of them will actually make use of the films they shoot.

You can edit your videos right and home and fully enjoy them with family and friends. You just have to download a free digital video software and set up the editing system. Then, within an hour you should be able to edit the films. However, things go a lot more easily when you are familiar with computers. The software transfers the data from the hard disk of the camcorder, and then processes them without altering the quality of the initial files. The procedure is also known as non-linear editing.

The processing program or the digital video software will then allow you to edit and rearrange the pictures or images just as you want. Thanks to digital encoding you can move to any part of the video during the editing process skipping or cutting some fragments without changing anything from the source materials. This means that if you are not happy with some of the changes, a digital video software lets you go back to a previous work stage. Plus, you can add all sorts of effects to the video.

Thus, with a digital video software both amateurs and professionals can create great transitions between the shots, swirls or ripples. Plus, you can further restore the quality of the pictures by using special cleaning filters. You will add graphics, titles and even animation in a very much similar manner. 3D effects are really great here and lots of network productions rely on them. The digital video software couldn't get more rewarding than this.

Most of the effects mentioned above will be achieved by means of CODECS or compression/decompression algorithms that make video editing possible. The most common of computer CODECS are DV, MPEG and MJPEG, and they are usually incorporated in the operating system. If this not the case, you can download them for free from a large number of sources on the Internet.

Digital Video Recorder

The invention of the digital video recorder has brought a revolution in the way people capture motion pictures. We no longer have to use magnetic tape to shoot a film; plus, video recording is within the reach of the amateur now more than ever. Each average household has at least one basic type of digital video recorder, not to mention the digital cameras incorporated in cell phones, smart phones and PDAs. What is so special about the digital video recorder or DVR?

Well, first of all the digital video recorder replaces the older video camera recorder or VCR by its capacity to record motion pictures directly on a high-capacity hardware drive disk. The storage capacity or size enables a certain mode of operation. Then, typically a digital video recorder can record in 1 hour, 2 hour, 4 or 6 hour mode with a higher or lower impact on the image quality. One other main advantage of traditional VCRs is time-shifting.

A digital video recorder can record a TV program that you will watch later, when you choose. This feature is enabled by the use of the hard-drive that requires no tape for the recording process. For example you can start the digital video recorder for a certain show, then you can pause the program, and be back in 15 minutes and watch it from the beginning. Yet, the digital video recorder will continue to record regardless of what you are watching. This is the most illustrative example of time shifting.

For an optimal operation of the digital video recorder, the user must follow the programming guide so as to be able to select the shows to record. Sometimes interactive menus are also possible allowing you to record a show for an entire season, or just daily or weekly. There are plenty of customization features that you can further take advantage of. And you don't need any technical skills or knowledge to actually create the settings for the digital video recorder.

The DVR will normally include a section with all the saved programs that you can view at any time you want. You just have to navigate through the saved programs and select something to watch. The rewinding and fast-forward features are available similarly to the use of the DVD player. More complex digital video recorder models can record one program while you are watching another, yet, most consumers still use the one tuner model that records only the channel that you are on.

Digital Video Cameras

Get the best features you can afford: this is the major deal with digital video cameras. The sales for electronics have dropped over the last two years because of the financial crisis, which has forced producers and retailers to change their marketing approach and the pricing structure. The offers for digital video cameras can therefore be a lot more rewarding than they used to a couple of years ago. The actual use of the camera is essential when shopping for the right model.

The main categories of buyers for digital video cameras include travelers, film makers and hobbyists, parents with children or who are expecting a baby, retirees and gadget lovers who want to have the latest toy possible. Sometimes a consumer has many other reasons. The problem is that people do not know how to choose their electronics.

Do not rush for a digital zoom because it does not improve the quality of the videos you film with your digital video cameras. They just give you an enlarged version of the best optical zoom that the camera can support. If you really need a zoom, then use some after market add-on lens to enhance the optical abilities. The resulting video will look really great.

The wide angle shooting is an essential feature of good digital video cameras. How far away do you have to be from the subject to shoot a good video? Try to shoot a video with someone next to you and you will see how good the video it is. You can check this feature of the digital video cameras right in the electronics shop, in order to know what you pay the money for. This is not a must-have feature unless you have to shoot at very close angles.

Good digital video cameras have to perform well even in low light conditions. You can check this feature by shooting in the conditions of normal interior lighting not when there are bright lights on the sales floor. Talk to the shop assistant to let you run a demo to check this feature in order to make sure that the camera performs well in all sorts of light conditions.

Digital video cameras are smaller or larger, and you should choose those models that make a good fit. This is one of the reasons why online shopping could be problematic because you cannot hold the device and see how easy it is for you to operate. It all depends on the kind of filming you have to perform, and while sometimes a camera that fits the purse is enough, on other occasions you may have to use a separate bag to carry it around.

Digital Video Surveillance

Digital video surveillance is part of our daily life. The cameras follow us when we go shopping, we get cash from the ATM, when we pay our bills or when we travel by plane. We are so used to their presence that we don't even notice them anymore. Yet, digital video surveillance never sleeps and it provides very serious information for lots of forensic investigations. There may be limitations to the systems and the way they work, but professional digital video surveillance seldom fails.

Lots of companies and institutions depend on digital video surveillance for security purposes. Recorders represent the very core of digital video surveillance equipment, and their design is far from equal in terms of quality. With digital devices the data is digitized and stored on a special disk drive. Such technologies are now implemented almost everywhere replacing the analog video capturing that is obsolete and incapable to cope with the new security demands.

Airports, banks, insurance companies, government agencies, stores and lots of other businesses rely on digital video surveillance. Moreover, such surveillance equipment is also used for ATMs and in homes for personal security purposes. Digital video surveillance is within the reach of the average consumer who can choose a device that corresponds to personal needs. Digital devices are more convenient because of the storage and archiving features.

Thus, a digital video surveillance system allows for quick access to data, as one can access the events randomly, review them or freeze frames from the material. Digital technology is more expensive, yet, for extensive usage it represents the only viable solution as you can write on the disk over and over again. Complex surveillance systems receive images from multiple channels at time, recording the data from several cameras at the same time.

Digital video surveillance for real-time monitoring is a bit more expensive, yet, companies use it in order to constantly monitor activity in areas of high-security levels. Lots of crimes have so far been prevented thanks to the use of digital video surveillance. Mention must be made that such systems are very complex and they require professional installation and constant maintenance. Moreover, special personnel needs to be hired to follow the video images supplied by different cameras in various locations.

Home owners can decide to install digital video surveillance for security purposes. If this is your case too, contact a professional service provider to have everything installed and running according to the specifics of your property.

Digital Video Recording

Digital video recording is performed with a DVR or a PVR, a device that records a show or TV program in a digital format and saves it on a memory hard drive. Digital video recording is possible with a separate stand alone box, but there are many electronics that have the DVR incorporated: this is the case with computers and mobile phones that have built-in digital cameras. There are even television sets that are manufactured with an incorporated digital video recording system.

The time-shifting feature is essential for digital video recording because it allows for the instant replay of the most interesting scenes, advertising skipping and pausing live TV. Microsoft heavily supports the DVR industry by the softwares designed and incorporated in PCs. Digital video recording has now extended to web applications and enjoys a more extensive public support than ever before. To understand the phenomenon it suffices to say that lots of satellite and cable service providers have incorporated digital video recording features in their set-top boxes.

With the growing dominance of digital television, digital video recording gained one further step to massive dominance since the digital stream broadcast by the channel is stored directly on the memory disk. One other major improvement of the functions came with the introduction of the dual tuner in 2003. Thanks to this new feature, digital video recording can be in progress on one channel, while the user watches another one.

Nevertheless, a much bigger progress appeared with the launch of the camcorder that combined the digital video recorder with a camera. Moreover, recording, capturing and editing entered a new phase of evolution. The advantages of such a technology are very numerous, and we have come to use it extensively for a huge number of applications. Almost everybody now uses a camcorder when going on vacation or when trying to capture some very special motion pictures. Amateurish digital video recording has gained predominance.

The great part of digital video recording is that you don't have to be very skilled or have technical knowledge. If you have the right device, then electronics perform most tasks automatically and you can just enjoy them. Professional videographers do take digital video recording at a different level of editing and processing, but they have the tools and the skills to perform very complex jobs with highly evoluated camcorders. Just watch them at work and you'll see that it's an art and a science to shoot great digital pictures with a full manual control of the device.
