-      <td>The duration of the Block (based on TimecodeScale). When not written, the value is assumed to be the length from the timecode of one Block in a Track, to the next Block for that same Track.  In use this means that this element is only needed at the end of a Track (as there is not other Block available), or when there is a break in a track. An example of a break would be a subtitle that ends before the next one begins, in this case a BlockDuration is used to indicate the length of time the subtitle should be shown.</td>
+      <td>The duration of the Block (based on TimecodeScale). This element is mandatory when DefaultDuration is set for the track. When not written and with no DefaultDuration, the value is assumed to be the difference between the timecode of this Block and the timecode of the next Block in &quot;display&quot; order (not coding order). This element can be useful at the end of a Track (as there is not other Block available), or when there is a break in a track like for subtitle tracks.</td>
