Webcast - An Effective Means Of Communication Over The Internet
You normally watch on your television set via a cable or an antenna, live or recorded TV programs broadcast from TV stations. Webcasting technology allows you to watch on your Internet connection equipped computer/cellphone, similar programs Webcast by various service providers. The difference in the two is that the former follows a set schedule to which you are bound.
The latter being an on-demand service, provides you complete flexibility.
Webcast means transmission over the Internet or sometimes even purely over an intranet of streaming media to a single recipient or to multiple recipients simultaneously.
This article is about how webcasting is used to communicate over the Internet. Webcasting refers to 'linear streaming media transmission over the Internet'. It is an umbrella term that includes the complete process that begins with pre-production activities, streaming media production/recording, editing, encoding, effective storage on Web servers/CDNs and split-second on-demand retrieval, continuous transmission over the Internet, and ends with download/display on Internet enabled computers/cellphones. Streaming means 'continuous', just as a stream is continuous. Media can include video, audio, graphics, or purely data. Sometimes, you may not be in a position to watch live or recorded music video concerts on TV or radio, because of your busy schedule. In such situations, you need technology that offers you the flexibility to watch such programs at your own convenience on the click of a button. Webcasting technology offers you click-of-a-button flexibility to provide you any archived streaming media based on your demand, which TV or radio stations cannot provide. It can provide you distance education lectures, presentations, how tos, advertisements, radio programs, and television programs. It can also provide you music, video, movies, news, congressional briefings, teletext, Webinars (the Webcasting equivalent of seminars), new product unveilings, ideas, and knowledge or information in any field. Web conferencing is a special form of Webcasting. It requires special video cameras, other equipment, and accessories at the sites of all Web conferencing participants, who may be spread over all over the world. Web conferencing can be used effectively for a discussion between company executives, or as a Webinar. You need special software on your Internet enabled computer that can receive and display streaming media. The other aspect is that the Internet connection you have must preferably be of the broadband variety. That is if you do not want to wait for the period that a slow dialup Internet connection will take to constantly buffer the streaming media on to the relevant software that can display it on your computer. If you follow the above guidelines, and pay the requisite service charges to a Webcast service provider, you will be able to receive virtually any streaming media archived by the service provider, which you may be interested in. From the point of businesses, a Webcast offers an effective communication medium to market and sell their wares to their potential customers or to inform about new products that they may have developed.
