Abstract A data processing method and an apparatus thereof, which process EIA-775 OSD graphic data received from the outside based on IEEE 1394 standards by using a combined software/hardware method. The data processing apparatus includes a first data processor, in response to an interrupt control signal, for analyzing predetermined data among graphic data and processing the same to output control data, a second data processor for outputting an interrupt control signal to process the predetermined data when the graphic data, and for calculating a destination address and the size of graphic data excluding the predetermined data to be output according to the control data, and a graphic processor for mixing video data with the graphic data, of which the destination address and the size are calculated. A system bandwidth and the size of a chip can be reduced, and easy modification and debugging can be realized.
