Multimedia platform for recording and/or reproducing music synchronously with visual images

A multimedia platform for recording at least first music sounds in an information storage medium synchronously with a picture, comprising:

• a first data source producing a first sort of data containing pieces of first music data information representative of said first music sounds;
• a second data source producing a second sort of data containing pieces of video data information representative of visual images of said picture, pieces of first time data information representative of a first time defined from a first viewpoint, and a first time signal representative of said pieces of first time data information;
• a third data source having an information processing capability and connected to said second data source, said third data source executing a computer program so as to realize a plurality of functions, said third data source including
• a clock incrementing a second time defined from said first viewpoint and represented by pieces of second time data information and generating a second time signal representative of said pieces of second time data information,
• a comparator supplied with said first time signal and said second time signal that compares said pieces of second time data information with said pieces of first time data information to determine whether said second time is consistent with said first time,
• a modifier modifying said pieces of second time data information with the negative answer so as to eliminate a time difference between said first time and said second time, and
• a converter converting said pieces of second time data information to pieces of third time data information representative of a third time defined from a second viewpoint different from said first viewpoint;
• a recorder connected to said first data source and said third data source so as to store said pieces of first music data information and said pieces of third time data information in said information storage medium;
• and
• an image generator connected to said second data source for producing said visual images,
• wherein said first data source includes a musical instrument on which said first music sounds are specified and
• a code generating system monitoring said musical instrument for generating said pieces of first music data information specified through said musical instrument,
• wherein said second data source includes a video camera,
• wherein said musical instrument is an acoustic piano, and said pieces of first music data information are produced through a fingering on a keyboard of said acoustic piano, and
• wherein said third data source, said recorder and said image generator form parts of an automatic player piano based on said acoustic piano, and said video camera is connected to said third data source and said image generator through a cable.
