 ### Method of describing bitstream syntax
 
+Each syntax element is described by its name (using only lower case letters
+with underscore characters) and a descriptor for its method of coded
+representation. The decoding process behaves according to the value of the
+syntax element and to the values of previously decoded syntax elements.
+
+In some cases the syntax tables may use the values of other variables derived
+from syntax elements values.
