Abstract

In this paper, we propose the method in which a stream of multimedia data simultaneously transfers to the main memory and the multimedia processor from the network interface card using a conventional system bus. The proposed method can reduce the input/output time of multimedia data and improve the data stream in the system bus. Also, we compared the number of system bus accesses, bus cycles and data transmission time to the number of participants between the proposed method and the conventional methods in the multi-party video conference systems. The comparison results of performance anticipate that the number of bus accesses of the proposed method was reduced by 50%, and the total transmission time was reduced by 75% as much as the conventional method regardless of the relation of the participant numbers.
