+      <para>Those data formats consist of an ordered sequence of 8-bit bytes
+        obtained from JPEG compression process. Additionally to the
+        <constant>_JPEG</constant> prefix the format code is made of
+        the following information.
+        <itemizedlist>
+          <listitem>The number of bus samples per entropy encoded byte.</listitem>
+          <listitem>The bus width.</listitem>
+        </itemizedlist>
+
+        <para>For instance, for a JPEG baseline process and an 8-bit bus width
+          the format will be named <constant>V4L2_MBUS_FMT_JPEG_1X8</constant>.
