+/**
+ * The <i>Chunk Offset Box</i> table gives the index of each chunk into the
+ * containing file. There are two variants, permitting the use of 32-bit or
+ * 64-bit offsets. The latter is useful when managing very large presentations.
+ * At most one of these variants will occur in any single instance of a sample
+ * table.
+ *
+ * Offsets are file offsets, not the offset into any box within the file (e.g.
+ * {@link ISO14496_Box_MDAT Media Data Box}). This permits referring to media
+ * data in files without any box structure. It does also mean that care must be
+ * taken when constructing a self-contained ISO file with its metadata
+ * ({@link ISO14496_Box_MOOV Movie Box}) at the front, as the size of the 
+ * {@link ISO14496_Box_MOOV Movie Box} will affect the chunk offsets to the
+ * media data.
+ *
+ * This box variant contains 64-bit offsets.
