| Outline of Final Research Achievements |
The high definition multimedia data is getting larger in these days. In order to transfer such data among information equipment with maintaining the quality, we require high performance communication techniques in Gbps order. Considering the characteristics of multimedia data, this research utilized the entropy reduction that human intuitively performs. Then, this research tried to find a new data compression mechanism that the target throughput in the communication data path was achieved stably. Because the multimedia data is a continuous data stream, we need to develop a new mechanism that continuously transfers without any buffering among the equipment. In this research, combining the cognitive entropy reduction and the stream-based data compression technique, we have developed a new realtime data compression mechanism for the multimedia data.
