Is there a difference between decoded picture buffer and coded picture buffer?

When it comes to H.264 video, is there a difference between Decoded Picture Buffer (DBP) and Coded Picture Buffer (CPB), or are they the same thing?

The coded picture buffer is a buffer that contains still compressed video data and is important for rate control of streaming video. The decoded picture buffer contains decoded yuv frames before they are displayed. They are not the same thing.
