This year's Royal Dublin Society Kerrygold Horse Show will have "shorter, slicker jumping competitions for visitor and TV viewer alike".
The chief executive of the RDS, Mr Shane Cleary, said it was clear that changes had to be made to the showjumping events as many of the competitions went on for too long or involved too many competitors.
He said both the Kerrygold Nations Cup on the Friday and the Kerrygold Grand Prix on Sunday would see innovations agreed by the society's equestrian committee.
The Nations Cup will be decided on the best aggregate time of three riders in the second round of the competition if there are equal fault totals at that stage. Also, only 30 horses and riders will be taking part in the Grand Prix and they will have to qualify.
The new "slickness" also clearly extends to marketing the Nations Cup because Mr Cleary said tickets for the grandstand were already sold out, as were half the tickets for the Anglesea Stand.
The Industries Hall has also been restored to its 1870s splendour and the corporate hospitality suites in the Grand Stand and Pocket have been refurbished, and a champagne and seafood bar has been established in the completely renovated private pavilion overlooking Ring Two.
Mr Aidan McCarthy, public relations manager of Kerrygold, the main sponsor, said 200 million television viewers would see teams from seven countries compete for the Nations Cup.
He said Britain, Germany, the Netherlands, France, the US, Belgium and Ireland would compete, and individual riders from Mexico and Norway would take part in other competitions.
The prize fund for the show, which runs from Wednesday, August 9th, to Sunday, August 13th, will be £280,000.
The event, which has been running for 132 years, will be formally opened by the Lord Mayor of Dublin, Mr Maurice Ahern, at noon on August 9th.
