What is Streaming Video

Video Streaming Explained 

Video streaming is a mono directional video transmission method over a data network.Its main purpose is to view video clips or vines and movies directly from the internet on the end users device, which can be a desktop computer, tablet, phone or even a TV( a desktop computer can also be used to stream video collections even from another server located in the home, or remotely over the internet in the cloud. All that would be needed for this is a server with large storage from which to pull the movies)This is a totally different concept from videos which are downloaded on your computer and then you play them at a later date. Streaming video or video streaming is actually when the video content is played immediately after the user presses play. What actually happens behind the scenes is that a small chunk of the video is downloaded in buffer memory, and from there is processed by the video player which is not stored on the computer’s hard drive permanently.

 Buffering Process

So the downloaded video is now in the buffer and playing, but then it starts to glitch, which is a term commonly known as buffering. This happens because the movie which is being video streamed or downloaded in chunks at a time and being played by the player, the internet connection cannot download more chunks fast enough to keep up with the rate at which the player is playing the downloaded chunks in buffer. This glitch or buffering can be really annoying and the only way to solve the issue is to either get a faster internet connection or to allow enough of the video to be downloaded so it can be played by the end users video player at a consistent rate eliminating the need to buffer. So to make the process a success both client machine and server need to be working in tandem so everything is smooth. What is happening is nothing new, streaming has been around for centuries, but its prevalence has is now ubiquitous because of its ease of use and its inexpensive modus operandi respective to a storage perspective. When streaming video and audio the content is being disseminated from a media-server, and is then processed and encoded or decoded by the video player or a web plugin (if you are doing browser based streaming, which is just watching videos over through the browser) into a form which it can understand, the server and end-user player work together to offer the smoothest broadcast of the information possible. Streaming has become extremely common because of recent booming services like Netflix, and hulu, which is used for video transmission and on the audio side, the likes of spotify, BBC radio one and last.fm.
