        The sample rate is described in the frequency field.
These values is
        dependent of which MPEG standard is used according to the
following table.

        Three bits is not needed in the decoding process at all.
These are the
        copyright bit, original home bit and the private bit. The
copyright has the same
        meaning as the copyright bit on CDs and DAT tapes, i.e.
telling that it is
        illegal to copy the contents if the bit is set. The
original home bit indicates, if
        set, that the frame is located on its original media. No
one seems to know
        what the privat bit is good for.
