1. A compressed domain compression apparatus for video, comprising:

  • a partial decoder that partially decodes an encoded piece of video to generate a partially decoded piece of video data;

    a least significant bit plane removal unit that removes at least one least significant bit plane from the partially decoded piece of video data to generate a modified partially decoded piece of video data; and

    a partial encoder that encodes the modified partially decoded piece of video data to generate fully compressed video data that is more compressed than the encoded piece of video data.
