What is a videocast or podcast?
A streamed webcast, or videocast, is a format for sharing and distributing video and audio data over the Internet. Digitally encoded video is stored on a server and electronically transmitted (streamed) from the server to a computer or portable device. The user of the computer or portable device can view the video as if they are watching a TV program, with the capability of pausing, rewinding, and fast-forwarding. No permanent data is stored on the computer or portable device.
A non-streamed webcast, or podcast, is a format that allows video and audio data to be transferred over the Internet and then stored on a computer or portable device. The video and audio data can then be viewed or listened to on the computer or portable device at any time. Large files may take awhile to download, depending on the speed of the Internet connection.
