Mr Gore will talk about his network, Current TV, during the Alternative MacTaggart Lecture, which was launched in 1997 to give an insight into the future of broadcasting.
Sir David will discuss new BBC documentary Planet Earth and a preview of the series will also be shown.
Armando Iannucci, the man behind shows including The Thick Of It and I'm Alan Partridge, will also give a masterclass.
Former Sun editor Kelvin MacKenzie and Respect party MP George Galloway will take part in a debate which will ask whether it is easier for those with right-of-centre opinions to get airtime on TV.
"This is a great line-up. I am sure they will make waves - and make news," said the festival's advisory chairperson, Alison Sharman.
The three-day festival, which begins on Friday 25 August, is open only to those who work in broadcasting.
