Examples of promising ISDB services are HDTV (high definition television), a variety of multimedia information and indexes. These services are transmitted using digital signals constructed with the MPEG-2 multiplexing scheme. ISTV (Integrated Services Television) has been developed as an ISDB receiver and experiments have been carried out to investigate services and suitable navigation functions of ISDB receivers. This paper describes the basic concepts of ISDB and ISTV, then discusses services and navigation in ISDB. A menu display function and an EPG display function are powerful navigation tools in ISTV. Examples of ISTV navigation are shown, and a theme for further study is reported.","PeriodicalId":393861,"journal":{"name":"ISCE '97.

In this paper, a body-worn type digital hearing aid (DHA) based on a dedicated DSP chip is developed. A fitting software running on a PC supported by the Win95 OS is also developed. The fitting protocol is based on the NAL-R procedure applied to eight frequency bands, but it is designed to support a curvilinear fitting to cope with the nonlinear perception of hearing-impaired listeners. Preliminary subjective tests regarding the speech intelligibility and perceived quality revealed that the new DHA could be of benefit to hearing aid users.","PeriodicalId":393861,"journal":{"name":"ISCE '97.
