Abstract
An apparatus and a method reduce delay when reproducing digital broadcasting in a mobile terminal. More particularly, the apparatus and method reduce a reproduction delay, from having to stand by until an encrypted stream that matches with a traffic key is received, by receiving the traffic key in advance prior to the encrypted stream when a mobile terminal receives encrypted broadcasting. The apparatus includes a controller. The controller receives and stores a traffic key corresponding to an encrypted channel even when not entering the encrypted channel, and deciphers and reproduces the relevant channel using the stored traffic key when entering the encrypted channel.
