マルチメディアMUSE : データチャンネルを利用したハイビジョン放送の高機能化

抄録

HDTV test broadcasting using the MUSE system was started in 1991. At present HDTV is broadcasting everyday for 11 hours. The MUSE system transmits sound signals in a digital scheme. The digital signal has a region which enables transmission of data other than sound called a data channel. Using the data channel, new broadcasting multimedia services can be provided. In this paper, service functions for the multimedia service are discussed. An experimental system to evaluate the functions for the service is developed using the MUSE data channel and the HDTV display. Experimental programs are also developed for evaluation tests.
