Webcast technology refers to the scientific method, material, and equipment that are used for the entire process from the creation of streaming media content upto a user's view of the webcast content. There are four major roles of webcast technology, which are spread over its entire lifecycle. Webcast technology comes into the picture right from the time of content creation. It is then used to prepare the content for distribution. Webcast technology then aids in the distribution of the content. Finally, webcast technology is used for consumption of the content by the consumer. The above four roles of webcast technology are discussed in detail in the paragraphs that follow.

The webcast technology used at this stage includes cameras, microphones, other recording and editing devices and computer software.
The role of webcast technology in the preparation of content for distribution - This is the stage in whivh webcast technology helps the preparation of content that was created in the earlier stages to make it fit for transmission. The webcast technology used at this stage includes encoders and converters, which compress the content so as to make it suitable for transmission through the distribution system, without choking the bandwidth of the webcast provider or that at the consumers end. Since multimedia files are very large in size, webcast technology reduces their size through the removal of redundant data, as well as to leave out such details as would not significantly affect the quality of the webcast content in a negative manner.
The role of webcast technology for distribution of content: This is the stage at which the webcast streaming media server comes into the picture.
