SP vs. LP modes (vs SDL): what the DV spec says? at DVinfo.net

Hi,
I am not into professional Video editing/production, but I have recently read the DV Specs (IEC 61834). So u can say that my interests are mostly academic, but I do not have much practical experience. Only fiddled with a few consumer camcorders.

The standard does not talk about the LP mode (or maybe I did not read carefully), but the few consumer camcorders I have come across allow options to record in SP/LP mode. Are these two recording modes fully compliant to the "SD" spec (IEC 61834-2)? It seems to me that SP recording is fully in accordance with the "SD" spec, and LP is not ... and the difference is in the error codes, system (aux) information, etc. (i.e., the audio/video coding of the two modes are the same). Will appreciate comments/feedback on this

A google search on DV and SDL shows that a few Canon Camcorders support the SDL format (IEC 61834-6). How popular is the SDL format, and do the industry folk think that it will proliferate?
