«How Streaming Works
A very simple analogy to illustrate how streaming works is be that of taking a bath (a 'download') in contrast to a shower (a 'stream'): when taking a bath it's necessary to fill the tub with water to the desired level before getting in, whereas with a shower you can turn on the water and get in straight away!
Typically with a shower the flow rate (or data) is lower but you can actually finish sooner as you don't have to wait so long at the beginning.
With streaming, content can be played even while the data packets are still being sent over the network, so there is no need to wait until a complete file has been fully downloaded. Therefore a song or movie can begin to play after only a very short delay (a few seconds in most cases).
And unlike a download no file is ever stored on the device; instead it has "streamed" through in its entirety but can easily be viewed again by repeating the process. Usually the stream requires consistent throughput (i.e. a steady network without too many variations) to give a good user experience, although some mobile streaming systems such as Vidiator's Xenon Streamer maintain the streaming quality even in varying network conditions that are inherent in wireless networks.
Benefits of Streaming to the Consumers
The key benefits of streaming to the consumer are that it requires no storage on the mobile and allows access to a vast library of content with minimal delay to start playback.
Some streaming servers including Xenon support user-created playlists, to play songs in the desired order or in a randomized shuffle mode. A music streaming service can be considered a network-based MP3 player giving the consumer their own personalized listening service.
With all these advantages, one may wonder why downloading still dominates the mobile music services available today?»
