Hi - I know this is not DIY, but there seem to be people here who have knowledge of a lot of issues.
I've just seen the QI DVD "Come Duncing" - in which Steven Fry asks questions and teams compete with their answers. Each team selects their answer, and you then see and hear the correct answer - and the programme somehow keeps a tally of the score. At the end of each section you can see the score for each team, and Fry announces who is the winner. But how? This is just a DVD, being played on a non-recordable DVD player, feeding into a TV set. Does anyone know which wizardry is used to store scores and calculate and compare totals, then presumably selecting which DVD clip to play to announce if the winner was team A or team B?
Cheers
