ABSTRACT:
A DVD (Digital Video Disc) player includes a system controller for controlling an overall operation of the DVD player and an audio/video decoder for decoding DVD bit stream data into audio and video data. The system controller transfers a key input indicative of a menu playback request by a user to the audio/video decoder. The audio/video decoder highlights a selected menu item according to the key input by using highlight information in a control pack of the DVD bit stream and transfers control information for the selected menu item to the system controller. Then, the system controller plays back the menu item according to the control information. The control information includes an executed button number and a button command to be executed.
