What is Video: Definition and 722 Discussions

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode ray tube (CRT) systems which were later replaced by flat panel displays of several types.
Video systems vary in display resolution, aspect ratio, refresh rate, color capabilities and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcast, magnetic tape, optical discs, computer files, and network streaming.

    Streaming video, how does it work?

    How is live video streamed on the internet? Since live/streaming video of course cannot be a single file. So how? Is it sent in small pieces or does data constantly flow from the source to the viewer? If so, how large is each piece?
