In the Computer Systems and Network Engineering Area, research is carried out on configuration technology of information and telecommunication networks, and its elemental technology. Specifically, this area includes fields such as network configuration, network control, network management, switching systems, wireless communication system, mobile communication network, satellite communication network, broadcast system, communication protocol, distributed computing, image coding and etc.
Although the fields in this area were conventionally divided into categories like switching and transmission, wired and wireless, telecommunication and broadcasting, the boundary between them has becoming indistinct in recent years. For example, for switching in the field of mobile communication network, it is necessary to take the characteristic of wireless communication into consideration. Furthermore, communication networks have already started to provide the same services as broadcast networks. Therefore, in the Computer System and Network Engineering Area, in order to achieve these network services, research is carried out by taking consideration from various perspective, without restraining on a single narrow field.

From the perspective of art and engineering towards multimedia, researches are carried out on fields like movie representation, media art, multimedia representation, audio and language information processing, image processing, cyber-space representation and etc. Researches are carried out not only discovering new knowledge in these fields, but also the integration product of art and technology. The representation and archive/distribution of multimedia content such as digital cinema, CG movie, audio/acoustic and etc., together with its human friendly reproduction techniques, and the challenges of integration with existing media are researched from a systematic perspective, including the interrelated research fields.

In this area, the objective is to help students conduct interdisciplinary and professional research, primarily on interrelation of rapid changing socioeconomic aspects of info-telecommunications from the perspective of social institution and policies. Conventionally, socio-economy theory tends to regard information and telecommunication as exogenous condition. Therefore, the field is pre-occupied with abstract debates such as “Information Technology innovation and productivity”, “Asymmetric of information between government, corporations and financial institutions with individuals, households and investors”, and etc. However, the relation of individual economic activities is getting more vivid with info-telecommunication nowadays. Therefore, in this field, in addition to major international thesis and domestic research outcome, the specific challenges arisen through the process of broad introduction of info-telecommunication innovation to social economy is also tackled.
