Digital Videos (DV) capture images on CCD – Charge Coupled Devices but store them in a high-quality, endlessly reproducible, easily edited, digital format. Currently the most commonly device for capturing videos is the Digital Camcorder.

The quality of the digital video is far superior to the analog counterpart. The images are sharper and the color is richer and more accurate, at least twice as good as the older VHS and almost identical to broadcast quality video as DV uses component color sampling to hold thrice the color information as a conventional analog VHS and S-VHS video.

Time Base Correction stabilizes the picture thereby virtually eliminating video jitters. Error Correction fills in missing video data and provides seamless, professional-looking video.

In a digital camcorder one can instantly change between video capture or playback mode without disturbing any of the other elements and can instantly review the quality of the captured video.

Editing video is greatly simplified because the video can be transferred directly from the camcorder to the computer without conversion using what is called as Firewire connection. It can then be digitally edited on-line and again copied back to a digital tape. Not only it is quick and easy, there is no loss of image quality as there is in the analog world while copying and transferring. In fact, copies of digital videos and copies of copies are still as sharp as the original. Once stored on the computer, you can also easily send short clips as e-mail attachments or post them on Web sites.

Digital videos have audio that’s CD quality, presently the best rated.

There is a convergence between digital still cameras and digital camcorders. Many of the new digital still cameras can capture short video segments and similarly camcorders can also capture digital stills.

DV cameras are smaller than other camera of other formats, with some even slipping into a shirt pocket. DV camcorders store upto ninety minutes of digital video on small DV cartridges, which are a bit expensive. Another feature of these DV’s is that images can be stored not only on digital videocassettes but also on MultiMediaCards known as Flash Cards and the images can be transferred between the two easily.

In its digital mode it stores in excess of 700 still images at 640 x 480 resolution in JPEG format in either of two quality modes. High Resolution mode will store approximately 60 printable images and Standard mode will store 105 images appropriate for email attachments. There are also zoom facilities available, which are normally 10x optical zoom and 40x digital zoom and are backed with an image stabilization system.

Downloading Podcast News

With the rise of podcasting, many individuals and organizations are finding that podcasting is a great way to distribute information, from music and comedy shows to talk shows, even podcast news. CNET is one of the groups that is distributing a news podcast. CNET, being an online technology site, naturally found a niche distributing a tech news related podcast. CNET’s recent podcasts covered such topics as viruses that attack cell phones, problems with Google’s software, China’s web restrictions and the “Great Firewall of China”, and the FTC’s attack on spyware. These news items were distributed in a sound file called an mp3 file that is downloadable to a listener’s computer for listening whenever they wish.

While these files were available straight from CNET’s site, the majority of them are shared through the use of an RSS file. An RSS file is a small piece of XML coding that is downloadable by programs designed to read it. These programs are called podcast clients, and the user can input the address of the RSS files that hold the information on the feed. The feed will contain links to the media files of the podcast, and will download the new updates automatically.

More sites than CNET are finding that podcast news is an expoitable technology. The British Broadcasting Corporation podcasts some of it’s programs, as well as the US radio network NPR. The NPR, because its work is created by a variety of different groups, treats podcasts differently from show to show. The NPR show “This American Life” distributes a podcast of the show through a site called audible.com, which allows feed listeners to subscribe to the feed for a small fee and download the show . The NPR Hourly News show, on the other hand, shares a short 5 minute broadcast that summarizes the news for free. Since the NPR is taking a radio show and converting it into a file that is downloadable by the user, little is lost in the translation. The sound is designed to convey the entire story, and so podcast subscribers are able to treate the podcast as nothing more than TIVO for the radio. ABC’s podcast of the news show Nightline, on the other hand, is simply the sound track from the television show. This has been one of the criticisms of the Nightline podcast, because by merely stripping the sound from what is designed as a television show, much information is not given to the users. Listeners have problems telling who is who because they miss the visual cues that were supposed to be there, and there is no truly easy way to convert the shows.

For this reason, some news shows have been moving from audio podcasts to video ones. They can take the video information directly from the show that is broadcast, lower the visual resolution to shrink the file, and distribute it online as a podcast.
