Streaming video technology lends itself to a wide range of recreational and educational applications—viewing user-produced videos on the Web, webcast delivery of live or on-demand TV programming and movies, interactive business training applications, long distance learning, and more. It allows end users to access content immediately, often using a standard Web browser, and enables media providers to distribute content without the overhead of physical media.
The spread of broadband Internet has allowed streaming media to evolve from jerky, postage-stamp-sized images into smooth and watchable full-screen video—but as technology improves, so do viewer expectations of quality. Streaming video can be affected by a range of network and equipment-related problems that may cause image corruption due to encoding errors, stops and gaps in playback due to buffer underrun, and poor audio-video synchronization.
