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 using a combined software/hardware method includes a first data processor, in response to an interrupt control signal, for analyzing predetermined data among graphic data received from the outside based on IEEE 1394 standards 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 is received from the outside based on IEEE 1394 standards, 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.
