<p>LarhondaSilverma: </p> <hr /> <div>Streaming technology has made listening to music or watching movies online as easy as turning on the radio or TV. Here is how the technology works.&lt;br&gt;&lt;br&gt;The first music and movie files you could find on the web were just short clips because you had to download the entire file before you decide to could play it. These days, [http://beauhorn.com/forums/users/arthrhpknson Beauhorn official website] on the other hand, you may start playing the file as soon as the first bytes begin to arrive... because of streaming.&lt;br&gt;&lt;br&gt;This immediacy is possible because streaming won't send files on the web the same way as most other files are sent. It uses a different protocol.&lt;br&gt;&lt;br&gt;A protocol is a set of rules defining how two computers connect with each other and just how they send each other data.&lt;br&gt;&lt;br&gt;Most data that's sent over the internet is first broken up into packets (small blocks of data). The packets are sent separately and also are the rejoined at their destination so that the receiver gets the entire file.&lt;br&gt;&lt;br&gt;The sending of most data on the internet is governed by a group of rules called the Transmission Control Protocol (TCP). Streaming however uses the User Database Protocol (UDP).&lt;br&gt;&lt;br&gt;Both of these protocols are quite different. The crucial difference is in how they check for errors.&lt;br&gt;&lt;br&gt;If one packet gets damaged when downloading will be controlled by TCP, downloading will be suspended while that packet is resent. That way, after the download has been completed, you can make sure that you've got the whole data file.&lt;br&gt;&lt;br&gt;When you are streaming files, on the flip side, UDP allows packets to get lost now and then without interrupting the downloading. This is fine because, when an occasional packet is lost, you are unlikely to notice any interruption to the music or movie. But if everything froze very briefly while a lost packet was being resent, you probably would notice the interruption.&lt;br&gt;&lt;br&gt;With streaming technology, you don't have to wait for files to be downloaded entirely before you can begin listening to audio or watching a video. You may listen to a concert on another side of the world in real time, make a video call or watch a movie just like on tv.&lt;br&gt;&lt;br&gt;Streaming video works in a similar way to streaming audio, except that the video has to be separated into its separate audio and video components when it's within the buffer in the RAM.&lt;br&gt;&lt;br&gt;The server that holds the video for streaming will have a video capture expansion card that may capture either a live feed from a video camera or perhaps a pre-recorded video. The capture board turns the analogue signals it receives into digital data and compresses it.&lt;br&gt;&lt;br&gt;At the exact same time, it employs a trick to prevent having to capture more data than it needs as a way to make transmission easier.&lt;br&gt;&lt;br&gt;In the event the camera used to record the video is stationary, ie, it's not panning, the total amount of data created can be reduced. This could be done because all moving images are made up of a series of frames (still images) that change in rapid succession to offer the illusion of continuous movement. The rate is normally 30 frames a second which gives the video a smooth look.&lt;br&gt;&lt;br&gt;The compression system lessens the range of frames needed by comparing adjacent frames and only taking account of pixels that change from one frame to another. It does this by establishing what the background looks like.&lt;br&gt;&lt;br&gt;As long as the camera remains yet, only the changes within the frame, for example the movement of the actors, have to be transmitted. The background only must be transmitted again once the camera starts to pan and also the background changes.&lt;br&gt;&lt;br&gt;Video streaming can even skip frames when your Internet link is slow, which may make the video jerky. Thus the faster your connection, the smoother the video will be.&lt;br&gt;&lt;br&gt;When your computer receives the video signals, it's going to decompress them and load them in to a small buffer in RAM as it does for audio.&lt;br&gt;&lt;br&gt;At this point the signals are split into separate video and audio components that are sent to the video card and sound card respectively, whence they may be output to your monitor and speakers so you can watch the film and hear the sound-track.</div>

Usually I choose songs from my famous films ;). &lt;br&gt;I have two brothers. I like Auto racing, watching movies and Yo-yoing.&lt;br&gt;&lt;br&gt;Also visit my homepage - [http://beauhorn.com/forums/users/arthrhpknson visit]</div>
