Research
Our laboratory is studing multimedia communication services. Especially, we is considering the service of audio-visual communication, and if we pay attention to video contents, there are some study issues of contents coding and providing methods according to userbility and data compatibility for any communication environment. Thus, we emphasize the improvement of a video coding schemes and a video distribution model using coded data for future services over network.
More precisely, a hierarchical coding, layer coding and scalable coding for data compression methods and new media services are studied with respect to a video coding method. On the other hand, since the stablility of contents service systems is one of significant issues for streaming , VoD and downloading services, coding control methods and service modeling schems for feasibility of them should be also considered. Consequently, the effect of whole systems must be evaluated as new systems.
Moreover, we focus on the research to pursue patents and to make fundation of industrial progress for ICT generation.
