Flash is the most common platform for providing audio and video streaming services in FLV format. FlashPlayer works in almost all online environments of personal computers and mobile devices.

FLV (flash live video) is optimised for online playback and live video streaming. It offers high levels of compression and ensures quality. You do not have to install any additional players (RealPlayer, QuickTime, etc.), since the Flash player is already installed in your browser.

There are two ways to transfer video to the web:
  • progressive streaming
  • server streaming

Progressive streaming is suitable for short video clips up to 15 minutes.
In this mode, the first part of the file is transferred to the user, the remainder of the file is saved to a temporary folder. With the help of Flash ActionScript programming language you can easily update content and embed content in the same player.

Advantages:
  • high quality video,
  • no streaming server is needed.

Disadvantages:
  • not suitable for the longer videos since the video must be downloaded to the user,
  • scroll forward/back is not available until the video is fully transferred,
  • protection against unauthorized use is not possible, because the video is transferred and physically stored in the user's computer.

Server streaming is used for playback of long videos and live TV as the file with the video content is not transferred to the user. It allows immediate viewing of the video on any part of the time scale. Scrolling back and forth is possible similar as with a home video player.

Advantages:
  • simultaneous display of video to multiple users,
  • control and monitoring of view statistics,
  • streaming of live video,
  • video on demand,
  • pay-per-view videos (also with DRM protection),
  • playback on mobile devices.
