    This paper describes an approach to the problem of finding songs in some sense similar to a query song. This is a problem of increasing importance, because consumers owning large digital music collections wish to navigate these and to add new songs by searching on-line. The technological approach is described, leading to the description of a simple demonstrator. View full abstract»

    In this paper we introduce our experiences in accessing Web Services (WS) from DVB-H terminals. As client should be as simple as possible, we propose to move its complexity to the DVB-H provider by defining virtual WS. Because of this visualization, the DVB-H provider makes the mobile client independent of the service location or availability and even makes the client QoS-aware. View full abstract»

    Optical disc recording technology using many types of write strategy (WS) has been developed for optical discs. The optimum WS for each disc is determined based on the material of recordable layer, recording speed, specification of the optical heads and so on. Parameters of WS should be determined by accurate tuning for each optical disc. It has been strongly desired to develop an actual auto-writ... View full abstract»
