Robin Williams -- Moment of Silence, Video Tribute at S.F. Giants Game

The San Francisco Giants will honor the memory of comedian Robin Williams during Tuesday night's game against the Chicago White Sox ... and TMZ Sports has learned what the team has planned.

We're told the team will observe a moment of silence before the game in memory of WIlliams. They've also planned a highlight video -- which will be played sometime between innings later in the game -- of various highlights of Williams' appearances at Giants games.

Back in 2010, Williams appeared on the field before game one of the National League Championship Series to rile up the crowd. They went on to win the World Series that year.
