Abstract
Abstract The data file recording method and reproducing system record musical performance tune signal in the form of MIDI information and background video signal on CD in order to store a number of playing tune signal. The recording method records on CD video information corresponding to and representing the meaning of the words of sheet music by measures. And the recording method records the musical performance information by measures following the video information, wherein the musical performance information includes a measure of MIDI information for playing a measure of a tune in the sheet music and exclusive information for synchronizing the musical performance information with the video information each for measure. The reproducing system comprises pick-up for driving a CD to read-out the data file from the CD, dividing circuit for dividing the data file from the pick-up into musical performance information and video information, playing tune generator for generating playing tune signals according to the musical performance information from the dividing circuit, and video reproducer for reproducing video signals corresponding to and representing the meaning of the words of sheet music by processing the video information from the dividing circuit.

Claim 5
Dependent Claim
211 words
A data file reproducing system for reproducing the video and musical performance information recorded on a CD, the system comprising: means for driving the CD to read out the data file recorded on the CD; means for dividing the read out data file from the driving means into the musical performance information and video information, said video information including a plurality of frame video signals corresponding to and representing the meaning of words in sheet music by measure; playing tune signal generating means for processing the musical performance information from the dividing means to generate playing tune signals; video reproduction processing means for processing the video information from the dividing means to generate frame video signals, said frame video signals having a plurality of images corresponding to and representing the meaning of words of sheet music; and video matching means for controlling the operation of the video processing means according to exclusive information contained in the musical performance information to synchronize the playing tune signal for tune of sheet music with the frame video signal corresponding to and representing the meaning of words of sheet music for each measure, such that as said playing tune signal is reproduced measure by measure said frame video signal is selectively changed after each measure.
Claim 6
Dependent Claim
211 words
A data file reproducing system for reproducing the video and musical performance information recorded on a CD, the system comprising: means for driving the CD to read out the data file recorded on the CD; means for dividing the read out data file from the driving means into the musical performance information and video information, said video information including a plurality of frame video signals corresponding to and representing the meaning of words in sheet music by measure; playing tune signal generating means for processing the musical performance information from the dividing means to generate playing tune signals; video reproduction processing means for processing the video information from the dividing means to generate frame video signals, said frame video signals having a plurality of images corresponding to and representing the meaning of words of sheet music; and video matching means for controlling the operation of the video processing means according to exclusive information contained in the musical performance information to synchronize the playing tune signal for tune of sheet music with the frame video signal corresponding to and representing the meaning of words of sheet music for each measure, such that as said playing tune signal is reproduced measure by measure said frame video signal is selectively changed after each measure.
Claim 7
Dependent Claim
