the dlcs are essentially the event quests you would have to wait for on a weekly basis on tri to access and would have to do so online.. i.e. you wait a week for the hot deal quest..have it for only that week before it cycles out and you have to wait a week or however long it takes to do it again. on mh3u either capcom or nintendo posts up the the event quest for download..via internet access you download the quest and have it forever and initiate it as you please.
