Live streaming media is the transmission over the Internet of video of an event as it happens. Streaming is a form of online video in which the site sends video footage to a user’s machine “on the fly” rather than as a complete file. It’s akin to the difference between watching a TV show as it airs and watching a DVD or erotic sex live cameras and stream .
Today, a media stream can be streamed either live or on demand. Live streams are generally provided by a means called “true streaming”. True streaming sends the information straight to the computer or device without saving the file to a hard disk. On-demand streaming is provided by a means called progressive streaming or progressive download. Progressive streaming saves the file to a hard disk and then is played from that location. On-demand streams are often saved to hard disks and servers for extended amounts of time; while the live streams are only available at one time only (e.g., sexwebcam or sex chat and video).
Live streaming media is different than on-demand streaming. With the latter, the content has previously been recorded. The user then accesses it at a time of their choice, though it is still streamed to their machine rather than downloaded as a complete file. YouTube is probably the best known on-demand streaming site.
The quality of live streaming media can be extremely variable. One factor affecting it is the technology the producers of the content have used to produce the streamed file. In some cases it may deliberately be kept to a small window size or low resolution.
The quality is also affected by the amount of bandwidth the website has purchased for transmitting the content. Generally, paid streams will be better quality. This is partly because paid customers are less tolerant of stuttering or low-resolution video. However, it’s also because a site charging for content will know exactly how many people will be watching and thus don’t run the risk of not having enough bandwidth.
Useful – and typical – applications of the “streaming” concept are, for example, long video lectures performed “online” on the Internet. An advantage of this presentation is that these lectures can be very long, indeed, although they can always be interrupted or repeated at arbitrary places.
There are also new marketing concepts. For example the Berlin Philharmonic Orchestra sells Internet live streams of whole concerts, instead of several CDs or similar fixed media, by their so-called “Digital Concert Hall” using YouTube for “trailing” purposes only. These “online concerts” are also spread over a lot of different places – cinemas – at various places on the globe. A similar concept is used by the Metropolitan Opera in New York.
The player loads but the video is stuttering or choppy, what could be the problem?
– In order to view streaming video you will need a broadband connection. Ensure that your connection speed is sufficient by visiting http://www.speedtest.net You should have at least 700Kbps downstream for reliable playback of medium quality video. Changing the quality on the player to low may improve this if you are on a weak internet connection.
– If you are on a wireless connection try switching to a wired connection, or move closer to the wireless router for a stronger signal.
– If you are running other bandwidth intensive programs you may want to quit out of these as they could be taking away from your available bandwidth.
– If you are on a shared internet connection others may be using bandwidth intensive programs that are reducing your available downstream bandwidth
– If you experience video stalling problems only during full-screen mode, try lowering your desktop resolution.
