WORTH NOTING ON TV
SUNDAY Trans-Antarctic Expedition (ABC, 7-8 p.m.): Six trekkers from as many nations will make an unmechanized trip to the South Pole - and it will all be covered live in five specials, beginning with this opener about the preparations and problems before the crew sets out - in the Southern Hemisphere's midwinter. National Audubon Society special (PBS, 8-9 p.m.): From scientists to spectators, they come each year from around the world to see the cranes' springtime arrival at Nebraska's Platte River. ``Crane River'' not only shows why, but deals with the river's dwindling flow and the dangers that poses to birds and people. MONDAY American Masters (PBS, 9-10:30 p.m.): ``Satchmo'' - last of three of specials on jazz greats - takes a personal look at the late trumpeter Louis Armstrong and the worldwide impact of his genius.
TUESDAY The Struggle for Democracy (PBS, 9-10 p.m.): One of the many hard questions history poses for democracy - how to reconcile majority rule with individual rights - is explored from a global viewpoint in ``The Tyranny of the Majority.''
P.O.V. (PBS, 10-11 p.m.): That's filmmaker shorthand for ``point of view,'' and also the name of this interesting series of independent documentaries made from an often strong personal conviction. In this edition, ``The Family Album,'' Alan Berliner edits the home movies of some 60 families - from the '20s through the '50s - to offer a vision of everyday life in America.
