Hi there, hmm...than u r taking diploma in advertising or degree in advertising? well...it depent on u what u want to learn about TV advertising. A TV advertising actually need graphic advertising + multimedia. for graphic advertising department , they concentrate more in how to apply the product in the commercial ( something like story board ).  well, for multimedia department, they will concentrate more in the making process, like filming, adding music n effect. Thats why u dont need to worry cause in the future, both actually get into one. But if u prefer to take the making process, better take multimedia. Hope that u understand what im telling cause my explanation isnt that good. sorry about that.
