The protest is the latest attempt by the League to win the £178m it is owed by Carlton and Granada's defunct digital broadcaster ITV Digital, plus loss of revenues from sponsorship and the non-televising of the matches.
The High Court case is set to begin later this month as the league attempts to wrest cash from the two ITV companies, which it is owed as part of the abandoned television rights deal its signed with the two.
The money will go to the cash-strapped Football League clubs. Many clubs faced financial ruin when ITV Digital said it could not honour the final two payments of a £315m three-year deal it signed with the league. Bradford City was placed into the hands of administrators soon after ITV Digital collapsed.
However, Carlton and Granada have washed their hands of the deal, saying they never signed a contract making them liable for the £315m deal ITV Digital inked with the league.
Today's action is to be followed by 12 further days of protest. The league has organised for six clubs to take part in the action each day.
League spokesman John Nagle called the action "another opportunity to highlight the outrage that is felt among league clubs".
He said: "We have tried to seek meetings with Carlton and Granada on numerous occasions and been knocked back and it was decided that the clubs would go and see them directly."
Last week, the league signed a new deal with satellite broadcaster BSkyB, although this was at the discounted price of £95m for the next four seasons.
However, many clubs are said to be unhappy with this deal, which gives first division clubs just £500,000 a year, down from the £2.7m a year they had been promised under the ITV Digital deal.
