What is SureStream?SureStream technology gives the best possible playback experience for different types of network connections. With SureStream, you can encode your source file for optimum streaming over, for example, 28.8 Kbps modems, 56 Kbps modems, and 112 Kbps dual ISDN connections. Users with 28.8 Kbps modems receive the stream at the lowest bit rate, while users with faster connections get a stream with better quality because of the extra bandwidth.
A SureStream clip can also "downshift" when a connection gets bogged down. Suppose a viewer starts out receiving a higher bit rate stream through a 56 Kbps modem. If the connection starts to sputter as the network gets crowded, Helix Server automatically downshifts to a lower bit rate stream. The audio or video quality drops with the lower rate stream, but the clip keeps playing. When the interference clears, Helix Server upshifts to the higher rate stream. RealPlayer doesn't need to rebuffer during this shifting. 
NOTE: To use SureStream technology your clips must be encoded using Real Producer or Helix Producer. If you do not have either software, we can encode your clips for a small fee. Contact support for assistance.
