DATA TRANSMITTER

摘要

PURPOSE:To allow a terminal to quickly and surely recognize desired data by setting a tentative access data area to a desired part of data stored in a central controller. CONSTITUTION:A storage means M1 stores sets of information in the unit of prescribed image and/or audio data such as information divided by each KARAOKE(orchestral accompaniment music). A central controller M2 sends designated data in a prescribed unit to a requested terminal equipment M3 upon the request. A part definitely indicating its data content for each prescribed unit data such as a 'highlight' part of a music is present to the storage means M1 as tentative access data in advance. When a request from the terminal equipment M3 is a tentative access request, the central controller M2 sends only the part of the tentative access data to the terminal equipment M3. The terminal equipment M3 makes a trial listening to confirm the data and sends a main access request to the controller M2, from which the terminal equipment M3 receives all prescribed unit data.
