1.  Introduction

1.1.  Loss Concealment Report Block

   This draft defines a new block type to augment those defined in
   [RFC3611], for use in a range of RTP applications.

   At any instant, the audio output at a receiver may be classified as
   either 'normal' or 'concealed'.  'Normal' refers to playout of audio
