Abstract: Audio/Video Streaming services enable us to watch videos or listen to music from anywhere and from any web enabled multimedia device like our personal computers or smart phones. All that the user requires other than a personal computer or a smart device are Internet connection and a user account on the service’s website. This will allow users to enjoy music anytime-while driving a car, taking an evening walk etc.. The need for Multimedia streaming arises from the following factors: First, storage capacities of our devices are limited .It is not possible to store all our favourite music/video files in them. Also new songs/videos are being added to the already existing list of millions of songs/videos on a weekly or monthly basis. Therefore, it is more convenient to stream from a service to our personal computers or smart devices connected to the Internet by logging into our account. Also, the need to frequently update the songs/videos on each device independently is eliminated. This saves time and money. Secondly, we are moving towards high quality audio/video. Streaming enables us to consume high quality audio/video without the need of high end hardware on the consumer side. Thus, it leads to reduced reduce hardware cost. We will discuss in this paper, how streaming works and the protocols and codecs associated with audio/video streaming. An improvement over the currently used model is suggested. Finally, we will discuss the challenges and legal issues related with multimedia streaming.
