To provide a stream transmitting system for smoothly switching a terminal by shortening a buffering time required for switching the terminal for reproducing streams among a plurality of terminals.

A server 101 transmits a stream of data predictively encoded among frames. The server 101 includes a transmitting data generating section 116 for generating data of one transmission unit by adding at least one differential frame following the key frame that may be individually decoded and for generating a key frame for buffer formed by adding information about data of one transmission unit including a frame number, and an output section 114 for transmitting, at the transmission timing of the key frame, the key frame for buffer generated using the key frame to be transmitted at that transmission timing and for transmitting the desired frame at the transmission timing of the differential frame.
