    Abstract: A video processing apparatus includes a memory to store auxiliary video data therein; a data updating unit to transmit the auxiliary video data to be updated to the memory at a first transmission speed and update the auxiliary video data; a data processing unit having a second transmission speed which is slower than the first transmission speed, as a speed of data transmission to the memory, to read out the auxiliary video data stored in the memory and output it as overlapped with predetermined video data; a switching unit to connect either of the data updating unit or the data processing unit to the memory; and a control unit to control the switching unit so that the data updating unit is connected to the memory, when the data updating unit updates the auxiliary video data. Accordingly, the loading speed of the auxiliary video data can be enhanced.
