Image data displaying/saving apparatus and method for television with viewer screen display function

PURPOSE: An apparatus for storing/displaying video data of a television having an audience screen display function and a method thereof are provided to display the stored video data on a screen automatically during a power-off state or when switching a channel. CONSTITUTION: A video input unit(214) receives video data. A video memory(211) stores the video data temporarily. The video data of the video memory are stored into a flash memory(212) as video data for an audience screen. When the video data for the audience screen are stored, a memory control unit(210) controls an audience screen display function to store the video data of the video memory into the flash memory. When the video data for the audience screen are output, the video data are copied from the flash memory to the video memory. A video processing unit(202) receives the video data from the video memory to perform a video processing operation. The first switch(208) performs a switching operation between the video input unit and a video input terminal(200) to transmit the video data to the video memory. The second switch(201) performs a switching operation between the video input terminal and the flash memory to transmit the video signal to the video processing unit.
