RealNetworks SureStream SureStream allows different encoding rates to be combined into a single media file. The streaming server will choose the appropriate data rate for the prevailing conditions by negotiating with the player. The lowest rate, called a duress stream, is a backstop, and will be streamed if congestion is very bad. When you are calculating the server disk space, a SureStream file takes the space of the sum of all the components. Because only the Helix Server can extract the correct component, a web server will serve the file in its entirety, including all the different rates. Windows Media Intelligent Streaming This is a similar feature, allowing multiple constant bit rate streams to be encoded and wrapped in a single file. The streaming server will then stream the best rate for the current network conditions. Windows Media Encoder comes with predefined multiple bit rate profiles, but the profiles also can be customized to suit your special requirements. If you want to multicast a file that has been coded at multiple bit rates, only the highest rate will be transmitted. Drawbacks If you want to serve at different rates, then better results can be obtained by encoding a small picture at low frame rates for low bit rate streams, and a larger picture for streams at higher rates. So you may want a 480 360 pixel frame at 30 fps for a 1 Mbits/s stream and 160 120 at 6 fps for an ISDN link. Multiple bit rate encoding has to use the same picture size, so that the player can switch seamlessly between the different rates. The automatic rate-shifters have their uses, but are not a complete answer to serving the same content over very different networks. The big advantage is that the process of changing bit rate is invisible to the user. QuickTime and alternate movies This is a less sophisticated method of offering different bit rates. You can encode a movie as several separate movies encoded at different bit rates, and maybe with different language audio tracks. These are the alternates: The player follows a pointer to the master movie, which then references the alternate movies. The player negotiates with the server to request the correct alternate file for the player settings. 216 The Technology of Video and Audio Streaming
