/* Dirac packetizer, formed of three parts:
* 1) Bitstream synchroniser (dirac_DoSync)
- * - Given an arbitary sequence of bytes, extract whole Dirac Data Units
+ * - Given an arbitrary sequence of bytes, extract whole Dirac Data Units
* - Maps timestamps in supplied block_t's to the extracted Data Unit
* A time stamp applies to the next Data Unit to commence at, or after
* the first byte of the block_t with the timestamp.
