Default Technical papers for Dolby digital mixing

I've tried to search on dolby site and film-tech but as i found good papers i wasn't able to find answers to some questions.
As DTS had a cross-over filter for surrounds and LFE channel, dolby has not.

I've been told or i've read that dolby digital decoding (as dolby SR) put an low pass filter to the surround channels to avoid too precise effects on that channels. Is that true and if yes, at which frequency ?

The second question is about latency given to surround channels (20ms ?) for Dolby contrary to DTS which doesn't put any latency.

If someone can enlightening me...

thanks


that link provide a good but a little old paper... maybe there are more things like that in the dolby site hidden to innocent eyes..
