WORTH NOTING ON TV

* SATURDAY

Hall of Fame Game (ABC, noon to 3:30 p.m., EDT): It may not really be pro-football season yet, but true fans can get a whiff of it in the live coverage of this Hall of Fame game.

The teams are the National Football Conference's Atlanta Falcons and the American Football Conference's San Diego Chargers.

The annual contest - traditionally the beginning of preseason pro-football action - takes place at the Fawcett Stadium in Canton, Ohio.

Cops (Fox, 8-8:30 p.m.): Still the most honest and least manipulative of TV's ``reality'' shows, this no-nonsense documentary series - by now one of the more durable on TV - begins its seventh season.

The opening program once again puts cameras in patrol cars - this time with the Los Angeles Police Department. As usual, it proves a highly credible way of conveying the patience and courage required in routine police work. (The middle of the show's three segments involves a seamy episode some viewers may wish to skip.) * SUNDAY

Tour de France (ABC, 1-2:30 p.m.): Highlights of the world's most prestigious bicycle race, a three-week event that ended last Sunday. The focus of this special is on team tactics, the cyclists themselves, and even the French landscape, which some say is half the pleasure of watching the historic event.

Magical World of Disney (Disney Channel, 7-9 p.m.): Two 18th-century boys - an obnoxiously arrogant heir to a minor European crown, and an orphan of the streets named Jemmy - cross paths in a new Disney film called ``The Whipping Boy.''

Based on Sid Fleischman's 1986 novella, the screenplay has the prince deciding to seize Jemmy and make him the official whipping boy. It's an honor Jemmy would just as soon forgo, since its main function is taking the prince's punishment for him. Yet Jemmy's new position leads to adventures shared with the prince, in scenes filmed on location in France, the German woods, and a German castle.
