Webcast Programs - Some Important Aspects
Webcasts are used to transmit streaming media to users over the Internet. A wide variety of Webcast programs are broadcast over the Internet.
This article covers various aspects about Webcast programs.
The various Webcast programs streamed to users on demand over the Internet include live and recorded TV and radio programs, live music concerts, live events of interest to users in various fields, distance education lectures, and product advertisements. They also include congressional briefings and important launches of new products and services by businesses.
The difference between programs aired on TV and radio on one hand and Webcast programs is that the latter is an on-demand service, whereas the former follows a set schedule. Webcast programs are displayed on the screens of users' computers in small sized windows, unlike traditional TV programs, which can be displayed in full screen size. Most traditional TV news channels also broadcast the same content also over the Internet. They use the peer to peer network technology to Webcast news programs over the Internet to users. Streaming video is a Webcast technology that is used to broadcast live music band concerts over the Internet to users. This technology is used predominantly to all varieties of Webcast programs over the Internet to users. Another aspect of this streaming media technology is that audio visual streams cannot be saved directly on computers. This means that streaming media are not directly downloadable on hard disks. The cost of Webcasting programs over the Internet to users is either shared by users on a pay per view basis or predominantly by a cartel of sponsors. These sponsors share the cost of the entire Webcasting. The sponsors earn their revenue in turn through advertisements, which popup on users' screens. The cost of Webcast programs is still quite high, although of late their quality has improved quite a lot. This is due to the development and propagation of high speed broadband Internet in the world as well as developments in Webcasting technology.. For the display of Webcast programs on a user's computer, a player (software) is required to be installed on the user's computer. Popular players are Windows Media Player, Real Player, and Flash Video Player. A user can watch a program in the window of a player such as the above three. Some Webcast programs are amenable for being downloaded on the user's computer hard disk. Others cannot be downloaded. Many home users also upload home videos created by them through use of a Web camera to some service providers that distribute them to other users. Such services are predominantly free. There are many more aspects relevant to Webcast programs than can be covered in this brief article. The Internet would be the best place to find out about them.
