When encoding MPEG video, a Closed GOP is one that uses no referenced pictures from the previous GOP at the current GOP boundary. For example the GOP is closed when it starts with an I Frame and subsequent B Frames do not rely on I or P frames from the previous GOP. Also see Open GOP.

In the first sentence above, "When encoding MPEG video, a Open GOP is one that uses no referenced pictures from the previous GOP at the current GOP boundary" I think the word 'Open' should be changed to 'Closed'. This becomes pretty clear if you also read the definition for 'Open GOP'.
