 This block is mandatory and must be the last block of the stream. Tags are written after this block.
 
+== Streaming ==
+
+This file format can be used for streaming. The "SI" block is used as synchronization marker. The decoder will scan for a "SI" block and check the block CRC. Once the decoder is synchronized, it will start decoding. It's up to the streaming server to choose when to send "SI" block.[[BR]]
+There is currently no way to send tags during playback. This must be changed (a tag block ?).
