Digital Televisions Are Hot Right Now
By Trevor | July 12, 2007
If you remember the days before digital televisions when the whole family would congregate around the old black and white TV set, then you will appreciate how much things have changed in a comparatively short period of time.
Go and visit any of your local appliance stores and you will be amazed at the size of the digital televisions, as well as the clarity of the picture you are looking at.
However, I will admit that the clarity is always good if they are using a digital video source, especially HD.
If you think that there is not much point in changing then you will be amazed and change your mind very quickly.
It is noticeable that the resolution of an analog set is limping behind the superior resolution of a digital television set.
This means that when watching a football match you will be able to take a look at the goal line and not only see the players in amazing detail, but you will be able to tell whose shoes are unlaced and who will most likely trip over those laces at kick-off.

Copying Digital Video : An Easier Option
By Trevor | July 10, 2007
When you are copying digital video films don’t the days of video cassettes seem far off now?
Digital video has almost entirely taken over and those old plastic containers with tape that never lasted seem an age away…
… and what about if you wanted to copy them? You needed two tape recorders and an awful lot of patience. Even then the quality was never that good unless you had professional equipment to use.
It’s a much different story with copying digital video nowadays, I am talking of course about videos that you have recorded yourself!
Copying digital video is a whole new ballgame. There are no international standard issues and files, images, and videos can now be shared almost instantly across the globe.
If you use a camera with a USB port then copying and sending you videos across the web becomes child’s play.
With the help of some editing software you will be able to upload your digital video and then save it to your hard drive in seconds.
From there you can edit your film and send it via email to anyone you desire. Alternatively and perhaps more practically, you can post it to your website and save it as a file to the webpage.
The kind of technology that enables this kind of digital video copying is referred to as streaming video technology.

Digital Video Cell Phones
By Trevor | July 7, 2007
Cell phones have come a long way since the early days when they were bulky machines, you can now even get digital video cell phones quite cheaply.
But camera phones are nothing new, they have been making the headlines recently with kids using them to film bullying scenes.
Not the ideal form of promotion the makers of digital video cameras wanted but it certainly doesn’t seem to have harmed them.
It appears that the future has finally arrived, and it is most certainly here to stay. Did you know that digital video cell phones are now able to display streaming video that is sent over the wireless networks?
One of the first companies to perfect the technology was Samsung. They were first past the post in making the technology cheap and efficient enough to sell to the general public.
The basis for the technology is the MPEG-4 standard, digital video cell phones now allow download of video via email for the owner to view on its small screen.
So who wants to make use of this technology? After all viewing a small screen for any length of time is not easy on the eyes and battery life is quickly drained by video.

Digital Video Cameras Make VHS Obsolete
By Trevor | July 4, 2007
Using digital video cameras together with a home computer and decent editing software, you can produce a motion picture-quality video that would rival Hollywood filmmakers.
After all George Lucas managed it with Star Wars, Episode II. So there is no reason why anyone can’t. George used digital video cameras to shoot the entire movie in digital format, which was the first movie ever made that way.
The old movie films during the 1950’s were typically about 50 feet long, although 100-foot rolls were available in 8mm and what later became known as Super-8.
The quality was far away from what we expect today from modern digital video cameras.
Pictures were subject to shaking, most cameras had no zoom capabilities and making an exact copy was virtually impossible to do at home.
Before long, movie cameras advanced to using video tape. Initially, two versions of tape emerged with cassettes which in the UK were known as VHS and Betamax. .
The first of the digital video cameras was developed by Sony, the Mavica. This was the first digital camera aimed at home use.
The Mavica was actually a movie camera taking still frames, because of this it was only natural for digital movie cameras to evolve from the rapid growth in technology.

Digital Video Technology First Adopted By Television
By Trevor | July 2, 2007
It is hard to believe that modern video technology has only been with us for the past 50 years. So much has changed during that time culminating in current digital video technology that is taken for granted by many.
The first video tape recorder was developed by John Mullin a research engineer who worked for Bing Crosby Productions back in 1951.
Bing Crosby helped to fund the research that created the first recorder, this converted the images from the television cameras into a digital signal and saved them to magnetic tape. The road to the development of digital video technology had begun.
The National Aeronautics and Space Administration switched from analog to digital video technology when they were mapping the moon’s surface in the 1960s.
The digital video images sent back to earth were fed into new computer technology, which was just being developed at that time, to enhance the photos for better visual rendering of the photos.
