Apparatus and method for displaying a television video signal in a mobile terminal

A method for displaying a television video signal in a mobile terminal with a display unit, said display unit comprising a video data display area and a user data display area, said method comprising the steps of:

• in a television mode, controlling a tuner to select a desired channel;
• receiving a television video signal of the selected channel and converting the received video signal into digital video data;
• scaling a size of said video data to a frame size;
• and
• storing video data of a current frame received over said selected channel and user data corresponding to said selected channel in a memory, outputting video data of a previous frame stored in said memory to said video data display area of said display unit in a frame period and then outputting said user data stored in said memory to said user data display area of said display unit upon completing the output of said video data of said previous frame, wherein the storing step comprises the steps of:
• storing said user data into a first memory;
• storing said television video signal into a second memory sequentially on a frame basis;
• storing, into a third memory, a previous frame of said frames stored in said second memory upon said video signal being stored into a second memory sequentially on a frame basis,
• storing, into said second memory, a video signal of a current frame that is output during said scaling step, at the same time, outputting video data of a previous frame stored in said third memory into a video data display area of said display means, and, then, outputting user data of said first memory into a display area of said user data upon completing the output of said video data of said previous frame,
• wherein said outputting step stores a new current frame into said second memory and, at the same time, stores, into said third memory, a frame stored in a second memory as a previous frame prior to said current frame being stored.

A method for displaying a television video signal in a mobile terminal with a display unit, said display unit comprising a video data display area and a user data display area, said method comprising the steps of:

• displaying menus comprising a television mode in response to a menu selection;
• in response to selection of said television mode, controlling a tuner to select a desired channel;
• storing video data of a current frame received over the selected channel and user data corresponding to said selected channel in a memory, outputting video data of a previous frame stored in said memory to said video data display area of said display unit in a frame period and then outputting said user data stored in said memory to said user data display area of said display unit upon completing the output of said video data of said previous frame, said user data comprising menus of said television mode;
• in response to selection of a screen capture menu, outputting a currently displayed picture as a still picture, outputting said still picture to a control unit of said mobile terminal to store the still picture, and then returning to said step of storing video data;
• in response to selection of a screen adjustment menu, rotating and scaling up the currently displayed picture and displaying the resulting picture on said display unit at a full screen size and, in response to reselection of said screen adjustment menu, returning to said step of storing video data to display the original picture;
• and
• in response to selection of an exit menu, exiting from said television mode and entering a communication mode.
