As he gave directions in the case against Mr Travis - charged with 13 indecent assaults and one sexual assault - Judge Anthony Leonard told jurors to forget he was famous as they deliberated their verdicts.
The judge said: "You won't be unaware that the Jimmy Savile inquiry has spawned a number of inquiries into various people who were well known in the 1970s and beyond. During the course of this trial alone Rolf Harris has appeared here and of course Bill Roache has been tried elsewhere.
"The verdicts of the jury in the Bill Roache trial are all irrelevant to your consideration of this case."
Coronation Street star Mr Roache was found not guilty of two counts of rape and four charges of indecent assault following a trial at Preston Crown Court. Mr Harris pleaded not guilty to 12 counts of indecent assault last month.
Judge Leonard told jurors they must ignore those cases, along with any media reports about Mr Travis's well-publicised trial.
"The fact that the defendant is a well-known personality does not change the rules of the way that you try this case.
"You must not allow yourselves to be overawed or deflated by the interest that this case has attracted."
Mr Travis, 68, is on trial under his birth name David Griffin, charged with indecently assaulting 10 women and sexually assaulting another in incidents dating back to 1976.
He denies all the charges, which relate to allegations from when he was working as a BBC DJ, with Classic Gold radio, while appearing on Top Of The Pops and when starring in panto.
The trial was adjourned to Monday when Judge Leonard will continue summing up before sending the jury out to deliberate its verdicts.
