“Courtroom Photographing and Broadcasting Prohibited Except as otherwise provided by a statute or these rules, the court must not permit the taking of photographs in the courtroom during judicial proceedings or the broadcasting of judicial proceedings from the courtroom.”
In recent years, SCOTUS has allowed audio broadcasting of case presentments before their court.
Different court, different rules. For real fun, try practicing in the Commonwealth of Pennsylvania where counties and even Judges have their own unique rules.
