videoPeople are drawn to video communications. Whether it's a football game on television, a streaming news webcast, or a video recording of the moon landing, video can provide motion pictures, animation, text and spoken words, music, sound effects, and other visual and auditory elements.

The term "digital video" refers to a combination of sounds and/or images that are represented in the form of numbers that can be read by an electronic device. Digital video can be shared through media such as CDs and DVDs, but it can also be shared over networks such as the Internet. Many formats are used to store the files and they are viewed using a player such as QuickTime Player, Real Media Player, and Windows Media Player.

Accessing Remote Collections

We all grew up watching broadcast, cable, or satellite television. Today, there are a number of variations on these options such as on-demand video. All of these systems brought video into the home, school, and library.

The Internet has brought a new option for transmitting video. There are two ways to access remote digital video collections. They can be downloaded or streamed. In some cases, the end user can choose which method they prefer. In others, only one option is available.

Downloaded video is copied from a remote web server onto a computer hard drive, CD, DVD, or other storage device. Many types of files can be downloaded including QuickTime and MPG. Macromedia Flash movies are another option. Downloaded video files can be placed on portable devices or played on the computer.

The major disadvantage of downloading video is speed. It can take hours to download a short video using a slow Internet connection. In addition, the video takes up storage space. The major advantage of downloading is availability. Once the video is on your hard drive it can be viewed over and over again. It can also be inserted into Word or PowerPoint documents and shared off-line.

Streamed video is also downloaded from a remote web server, but the files are only temporarily stored while they are being played. The most popular format for streamed video is Real Media media.

Using Remote Collections

The use of remote video collections is evolving. Until the 1990s, television was the major way to bring programming into your school, home, or library from the outside world. When the web was introduced in the early 1990s, few people had fast enough connections to download video. As a result most downloadable videos are very small video clips rather than full-length programs. With the introduction of faster connections and streaming video, viewing longer programs is now possible. Some people are even purchasing full-length motion pictures online.
