Needs Changing as Multimedia Progresses

In computer communications growing at a higher rate than other fields of progressing multimedia, the users' needs have been largely changing along with exponential advancement of LAN and terminal technologies.

Present Future Needs

Small-amount information transmission Large-amount information exchange Demand for high-speed communication of a large amount of data and information such as video images, typical of high-speed computer communications

Single function Multiple functions Demand for handling composite media of audio, video, and data instead of single media

Averaged service grade Various service grades Demand not only for conventional highly reliable services but for less reliable but reasonable services

Connection type (*1) communications Various communications systems including connection-less (*2) type Demand not only for telephone-based connection communications but for connection-less computer communications

Meter rate Diversified systems including flat rate Demand for flat-rate service independent of the duration of call or traffic
