Abstract: A multimedia device and a method for controlling the same are disclosed. The multimedia device includes a receiving unit configured to receive a broadcast signal, a display unit, and a controller, wherein the controller may be configured to control the receiving unit to receive a broadcast signal through each channel available for tuning, when a first command for executing auto channel tuning is detected, to verify a presence or absence of an Application Information Table (AIT) in signaling information included in the received broadcast signal of each channel, to extract information on an application related to a specific channel from an AIT, when the AIT exists in signaling information included in a broadcast signal of the specific channel, and to store the extracted information on the application in a memory.
