The prospect of enhanced application scenario

Challenge(1/2)

• DMB is being provided to users for free and Because DMB service carrier have to create their revenue by only advertisement fees, DMB services is being operated at a loss until now.

• However, By realizing the importance of mobile TV, mobile operators have begun aggressively data & interactive services to create additional revenue using T-DMB

• We believe that this standardization activities help to create new convergence services between broadcasting and communication below the following.
